What To Do With Deployed Airbags

A Motorist With Deployed Airbags

What to do with deployed airbags

When states first enacted mandatory car seats and seat belts, it was an adjustment for most of us. And once we got past the frustration of being told what to do, again, we come to understand it was for our safety. And so, this safety concern continues with manufacturers required to install air bags and car owners are required to keep them.

How do I get rid of air bags?

The air bag installed on the steering wheel is a part of the steering wheel assembly. Typically, the airbag is attached to a fuse that will need to be disconnected before removing the air bag in a safe manner. For most cars, it can be done within an hour if you have the right tools. 

The air bag removal process can vary with each make, model, and year of a car. The basics, once you have disconnected the battery and the fuse, is to turn the steering wheel to the left for 180 degrees. This should put the other side of the steering wheel on top. Next, position a flathead screwdriver on the right into the hole. This should pop the air bag out where you can grab and pull it out. 

What happens if you remove an airbag?

The first thing you’ll notice when you disconnect or remove an air bag, the dashboard air bag light will illuminate. Next, you should know that any vehicle that falls within the State of Illinois safety inspection process will fail the inspection. 

It is a federal law that car manufacturers must install air bags in any vehicle made after 1999. Whether your car will pass the state’s inspection will be determined if the inspector checks that the air bag is in place and in working order. 

At what speed of impact do airbags deploy?

According to the NHTSA (National Highway Traffic Safety Administration), you will need to reach speeds between eight and fourteen miles per hour before your air bags will deploy upon impact. 

However, the car you’re in doesn’t have to be moving for air bags to deploy. If you’re sitting still in a running car and you’re hit by another vehicle traveling between sixteen and twenty-eight miles per hour, the air bags will deploy. If your car engine isn’t on and you’re hit by another vehicle, the air bags won’t deploy. 

How do I start my car after airbags deploy?

Every car manufacturer has implemented different methods to prevent a car from starting once it has been involved in an accident that caused the air bags to deploy. This is done by programming certain systems automatically disconnects, like the battery, fuel pump, or starter, and sometimes the fuses blow. 

The things that you may notice after an impact that caused the air bags to deploy include: 

  • The engine won’t start
  • Ignition turns but there is no power to anything
  • Ignition doesn’t turn on.
  • Warning lights on the instrument cluster illuminate
  • The SRS malfunction light on
  • The EBS malfunction warning on
  • Fault code for the Engine Control Module engages

Things that you may be able to bypass to get your car started again: 

  • Check the fuse block and replace any blown fuses
  • Check the battery
  • Disconnect the antitheft system

Can you fix airbags once deployed, or is a car totaled if airbags deploy?

No, deployed air bags does not mean your vehicle has to be totaled. But the air bags cannot be repaired, they will need to be replaced. If the cost of replacing the air bags is more than the value of the car, it is up to your insurance company to declare the car a total loss. 

Can I cut off deployed airbags?

If the air bags have been deployed, they cannot be reused, so removing them is the only option. It is best to have an authorized repair facility do the removal, but if you’re needing to drive the car, you can cut them out using a knife or scissors. Be prepared to clean up the power that comes out of the deployed air bags. 

Is a car worth fixing if the airbags deploy?

It depends on the value of your car.  Replacing air bags is expensive, but your car may have a high value. For example, a 2022 Mercedes Benz would be well worth paying to have repaired and the air bags replaced. However, a 1999 Chevy may not be worth as much as it cost to replace the air bags.

Ending With a Frequently Asked Question

Are airbags covered under insurance? If the accident isn’t your fault and the insurance company doesn’t total your car, your policy (or the at-fault driver) insurance will pay for the air bag to be replaced, if you have collision coverage in your policy covering the car. If the at-fault driver doesn’t have insurance, it will be up to your insurance company how to pursue the matter, like suing the other driver.

Is it Worth it to Repair an Engine?

car service, repair, maintenance and people concept - auto mechanic man with lamp working at workshop


Buying a car and keeping it insured are expenses we expect and can budget. But those car engine repairs are an expense that is typically unexpected.  So, can engines be repaired? Maybe, maybe not. 

If your car engine troubles, there may be car engine repair options, depending on the location and severity of the damage. If the engine damage is contained to a part or specific system, repairs may be possible. Like replacing the fan belt or a hose. 

If the problem is with a larger component or system, like the radiator or transmission, a car engine repair may cost more than the car is worth. This is a decision you’ll need to make after talking to a mechanic that knows how to repair a car engine.

What parts are in the engine of a car?

Under the hood of a car are over 30 components and parts that make a car run. Too many to list in this article, but the 5 biggest components are: 

  • The Engine Block
  • Camshaft
  • Crankshaft
  • Cylinder Head
  • Pistons

Any car engine repair needed for these components is when the decision if repair is a viable possibility. 

What is a major engine repair?

Major car engine repair is repairing or replacing the engines, power train, or transmission. This can involve all or part of the following: 

Replacing damaged parts using OEM or equivalent parts, new or refurbished such as: 

  • Piston rings
  • Bearings
  • Gaskets
  • Seals
  • Camshafts
  • Crankshafts
  • Pistons

Major car engine repairs often include reconditioning internal surfaces like the cylinders and/or the cylinder head to give the piston rings a proper seal. A proper seal is needed for how car engines work with the following process: 

  • Cars that have a gasoline engine will have a 4-stroke combustion cycle that converts the gasoline and makes the engine run and puts the car into motion.  Internally the engine has pistons that are connected to the crankshaft with a rod. When the crankshaft revolves, it goes through a cycle of the following steps: 
  • The piston begins at the top and the intake valve opens. This allows the piston to move down, and this allows the engine to take in air and gas in the cylinders, aka, the intake stroke. Then the piston moves up and compresses the gas/air mixture and that compression explodes more power. 
  • As the piston stroke reaches the top, the spark plug sparks and ignites the gas, which charges the cylinder to explode, pushing the piston down. After the piston reaches the bottom, the exhaust valve opens and the exhaust escapes through the tailpipe.

How much does it cost to repair a car engine?

Car engine repair costs can vary from the make and model of the car, and the size of the engine. The biggest factor that will determine the price is the amount and type of car engine repair needed. Replacing a belt or hose is less expensive than replacing a piston or repairing a cylinder.

Is it better to repair or replace an engine?

Replacing a car engine is sometimes a more affordable option compared to a car engine repair. Factors to consider include: 

  • Warranty coverage: If the car is new enough, the engine may be covered by a manufacturer’s warranty. 
  • Insurance coverage: If you have engine insurance, replacing the engine may be the better option, depending on the deductible. 
  • The Cost:  If you don’t have engine insurance or a warranty, car engine repair may be the better option within financial limits. If the car engine repairs are outrageous, buying a new car may be the better option.

If the car has a sentimental value, car engine repair costs may not even be an issue for you. Examples would be if it is your first car and you want to keep it, or if the car belonged to a family member and the car should stay in the family. 

Does car insurance cover engine replacement?

If you have full coverage on your auto insurance and have an accident that damages or destroys the engine, then yes, insurance will pay for car engine repair or replacement, if the accident is your fault. If the accident isn’t your fault and the at-fault driver doesn’t have insurance, your auto insurance will cover car engine repair or replacement. 

Lights, Camera, Action? 

Why is my service engine soon light on? There are several things that this could indicate, which are usually more involved than a routine car engine repair or service. It can be a system failure involving the emission system, fuel system, ignition system, or transmission. 

When this light comes on, pull over and check the gas cap. If it is not secure or has gone bad, this can cause the check engine light to illuminate. After securing or replacing the gas cap, if the check engine light is still illuminated, take your car to your trusted garage, and have the mechanic inspect the engine and transmission. It may be low on oil or have some other issue.

What are the signs of bad brakes?

bad brakes after being removed from a vehicle

Keep Your Brakes in Shape

If there is anything you’re going to skimp on with your car, brake repair is not the one to choose! Running out of gas or needing to jump your battery can be annoying. Not having any brakes is downright dangerous and scary! Just as important as having good tires and air pressure on the ground, you want to make sure your brakes are in good working order too. 

How can you tell you need new brakes?

The brakes on your car are essential for your and your passengers’ safety. They will often work for thousands of miles without any problems. And that can be a problem. They say the squeaking wheel gets oiled. That same thing can be said of brakes. The noisy, malfunctioning brakes need brake repair! 

Most of the time, your car brakes are quietly doing their job. So, what kind of sounds will tell you that you should take your car in for a brake repair job? Here are some tell-tale sounds you should be listening for: 

  • Squeaking: If you’re hearing a high-pitch squeak as you apply your brakes, it is probably because the brake pads are wearing thin. Brakes today have indicators built-in on brake pads that make shrill, squeaking sounds at a certain point. This is your notice that you need either a brake inspection or a brake repair. 
  • Grinding: Okay, what if you can’t get your car in the shop when that squeaking sound starts, what happens? You’ll start to hear a grinding, growling sound. What is the grinding noise when I brake? The brake pads have worn down further. If you wait much longer to get a brake repair job, the caliper and rotors will get damaged, and that brake repair job is going to be expensive! 
  • Responsiveness Reduced: Not only will brakes that are wearing out begin making noise, they also won’t be as responsive, meaning they aren’t going to stop as quickly as they have been. If you’ve noticed you’re having to start stopping sooner than before, or you’re pressing harder on the brake pedal, you need a brake repair service pronto! It may not be the brake pads, it could be the hydraulic lines where the brake fluid flows, or your car could be low on brake fluid. Regardless, if they aren’t working as they should, have them checked. 
  • Pulling: If your brakes are pulling to one side when you press on them, this is an indicator that you need to have them checked. Typically, this will be because the brake pads on one side of your car have worn differently than the other side. It could be the hydraulic lines too. Regardless of the reason, a brake inspection is needed now. 
  • Vibrations: A car will vibrate from time to time as the pistons move up and down rapidly inside the engine. That is not a bad vibration. Regarding the brakes on your car, the vibration is not good. It could be as simple as the front-end needing an alignment, or the tires needing to be balanced. It can also be worn-out pads or rotors. Take your car to get a brake inspection. 

Why is my car shaking when I brake?

As you drive your car, the brake pads accumulate dirt, dust, oil, and more and this can cause the brakes to vibrate when the pedal is pressed. If the rotors are wearing out or the pads are getting thin, excessive heat builds up and warps the rotors, resulting in vibration. A brake job will stop this shaking as the pads are replaced, possibly the rotors. 

How long do brakes typically last?

The average lifespan is 30,000 miles, and with each oil change brake pads are inspected to check for wear.

It isn’t possible to put an exact number on the lifespan of brakes. The average will typically be from 25,000 up to 65,000 miles, with some exceptions up to 80,000 miles. With proper maintenance and as little abuse as possible, 40,000 miles would be the number if you were to give an exact number.

For a safe and legal break job, you must either resurface or replace brake rotors along with pads at the same time. Nowadays most manufacturers only allow 1.5 millimeters to 2 millimeters from new until the replacement of rotors is required. Also, when you resurface the rotors, on average it takes around 15 feet more to stop. With how many people are driving distracted, 15 feet can be the difference between hitting somebody or not, if you have to stop quickly or unexpectedly. This is why we only replace the rotors with the pads at every brake job.

What causes brakes to malfunction?

The three most common issues for malfunctioning brakes are: 

  • Loss of brake fluid. Each time you push on the brake pedal, fluid transfers to the brake disks. If a leak develops in the lines or at the disk, your brakes will malfunction. 
  • The brake cylinder fails. The brake cylinder is a crucial part of a car’s braking system. This is where the brake fluid gets compressed; if the cylinder is bad, your brakes won’t stop. 
  • The brake booster goes bad. This part of the brake system takes the force pressing on the pedal generates and amplifies it. When the brake booster goes bad, the force you push onto the pedal will not produce.

Should you replace all your brake pads at once?

You don’t need to replace all brake pads at once, just the wheels that are bad, two at a time.

What are the symptoms of a bad brake line?

The brake lines are the pipe for the brake system. They are what helps works the hydraulic pressure, taking brake fluid from the master cylinder and sending it to the wheels. Most brake lines are steel because of the high pressure they are put under. There are three things that are telling you that your car needs a brake repair job:

  • Brake fluid leaking: This is the common indicator your brakes are going out. Over time, even though they are made from steel, they can get damaged and wear out, getting a small hole in them and start leaking. A professional brake repair job is needed. 
  • Warning Light: Like the check engine light, never ignore the brake warning light. This is telling you that something is right with the braking system, and you need to get your car to a brake repair shop quickly. 
  • Corrosion: When your brake lines become corroded, this usually means the lines are getting weak and starting to leak or it could be from exposure to the elements. Either way, your brakes need to be inspected. 

What happens when a brake caliper goes bad?

When brake calipers go bad, they will either freeze up or stick. When this happens, you’ll start hearing noises from the damaged part. Ignore getting a brake repair job for too long, the brakes could lock up and keep the wheels from turning. 

What happens if your brake rotors are bad?

When the brake rotors go bad, it can get dangerous driving. Not only is braking delayed, but the handling is affected and that can cause an accident. Once you have a brake repair where the rotors are replaced, your car will handle better.

In Closing

The brake system on a car requires regular routine maintenance and service. Each year as you get your car inspected, they will also inspect the brakes. As the driver, if you notice any of the things we’ve discussed, take your car to a shop as soon as possible for a professional brake repair job.

How often do you need a brake job?

close-up of a driver's shoe on the brakes

How often do you need a brake job?

While we’re concerned about what makes our vehicle go, we also need to think about stopping too. The motor, transmission, wheels, and tires, and all the other components that keep a vehicle are running and moving are important, and so are the brakes. That’s why when the brakes go bad, a brake job becomes a necessity. 

How do you know when your brakes are bad?

A vehicle with bad brakes is dangerous and it can get expensive if not addressed immediately. Some indications that your vehicle needs a brake job are: 

  • Brakes Pads: 

The brakes pads on a vehicle press next to a rotor on the front wheels. This creates the resistance that makes your vehicle stop. Over time, they begin to thin, and they get to a point where they can’t make the friction needed to stop the vehicle. A visual inspection can be done by looking at the spokes of the two front wheels. If you see a thin pad or nothing but metal, it is time for a professional brake job. 

  • Squealing Sounds: 

Newer vehicles today have a small metal piece that will make an irritating sound as brake pads get thin. Once you hear that irritating, shrill screech while depressing the brake pedal, it is time to schedule a brake job.

  • Poor Performance:

If the brakes on your vehicle aren’t working well, take the vehicle in for a brake inspection. This could be what they call a “soft” pedal, meaning that as you press on the brake you aren’t feeling it stopping the vehicle, requiring you to press harder. If the brake pedal is going all the way to the floor before it stops, your vehicle definitely needs a professional brake job. 

  • Vibration

When you press on the brake pedal and you feel it vibrating, this is the brakes telling you that it is time for a brake inspection and a possible brake job. Sometimes the problem is deformed rotors, in which case “turning” them to even them out is all they need. However, by the time this kind of work is needed, a complete brake job may be the better option. 

  • Driveway Puddles

Finding small puddles under your car can mean many things such as a leaking radiator, a leaking transmission, or an oil leak. It can also mean your car has a brake fluid leak, as it can be another sign of a leaking brake line. Can you repair a broken brake line? Yes, taking your vehicle immediately to a professional mechanic who knows how to repair a brake line is recommended. It is often safer with a broken brake line to have them come to collect your vehicle with a town truck instead of risking driving the vehicle. 

  • Pulling

If you feel your car going to one side or the other as you press on the brakes, you need to have your brakes inspected right away. 

  • Metallic Sounds

If your vehicle’s brakes make grinding metal sounds when you press on them you need a brake job now. This indicates they have worn through the brake pads, and if you don’t get them replaced soon, your vehicle is going to need even more extensive brake repairs.

  • Warning Lights

When the anti-lock brake light or “ABS” comes on and stays on, you have a brake problem that needs immediate attention. It may only need brake fluid added, but it should not be ignored. If a “BRAKE!” light comes on, it could be that the emergency brake is still engaged. If both lights are on, call your mechanic to get your vehicle in for a brake job. 

When is brake pad replacement needed?

The average lifespan is 30,000 miles, and with each oil change brake pads are inspected to check for wear.

Keep in mind that your driving habits will affect this, but the average brake life can be as short as 25,000 and up to 80,000 miles. Other factors that determine this are the quality of the brake pads and rotors. An average lifespan is around 40,000 miles.

For a safe and legal break job, you must either resurface or replace brake rotors along with pads at the same time. Nowadays most manufacturers only allow 1.5 millimeters to 2 millimeters from new until the replacement of rotors is required. Also, when you resurface the rotors, on average it takes around 15 feet more to stop. With how many people are driving distracted, 15 feet can be the difference between hitting somebody or not, if you have to stop quickly or unexpectedly. This is why we only replace the rotors with the pads at every brake job.

Can you repair a brake master cylinder?

The master cylinder is one of the most common brake job repairs needed. Over time, these begin to leak around the seal, and most of the time, they can be rebuilt. Each make and model of a car can be different in this regard and depending on how old the master cylinder is and how damaged it is, replacing the master cylinder may be required. 

Can you repair brake hoses?

Brake hoses usually require total replacement rather than a simple brake job when you are having problems with them. They become brittle with time, and repairing them isn’t possible. 

How long does it take to do a full brake job?

Depending on the make and model of the vehicle, a brake inspection will take between thirty minutes to an hour. This will include inspecting the brake pads, rotors, and other components of the brake system. A brake job can take between forty-five minutes to an hour unless the brakes are severely worn and damaged. 

close-up of mechanic working on car brake pads

Coming To A Halt 

So, how much does a brake job cost? It can vary from make and model to make and model; pads, and rotors only start at $345 per axel, and
new calipers start at $175 each. With higher-end cars, the brake job could cost up to $1,000 or more. With that expense, you may be asking how many miles should a brake job last? Your driving habits will affect this, but the average brake life can be as short as 25,000 and up to 80,000 miles. Other factors that determine this are the quality of the brake pads and rotors. An average lifespan is around 40,000 miles.

Will a clogged heater core cause overheating?

close-up of car heater knob

What is the Heater Core?

With fall coming in fast and winter already knocking on the door, you want to make sure your home heating system is in working order right? What about your vehicle’s heating system? It won’t hurt to have it checked out too, cause if your vehicle has a clogged heater core, you are going to have one cold ride to work. 

What is the heater core and why is it so important for helping your vehicle stay warm inside? Let’s review how the heater core works:   

A heater core is like a small radiator, with the key difference being it diverts the coolant in the motor from the cooling system and heats the interior of the vehicle. As the engine runs and warms up the coolant (aka antifreeze), the water pump sends it through the cooling system. It is passed through the main radiator to keep the engine from reaching a boiling point and overheating.

When the heater inside the car is turned on, a valve opens, allowing that heated coolant to flow to and through the heater core. There, a door opens, and the air is directed through the heated heater core. As the coolant reaches 200 degrees, it delivers heat to the vehicle’s interior. Depending on where you have the controls placed, it warms the feet or defrosts the windshield. If there is a clogged heater core, that heat won’t reach your feet or windshield. 

What are the symptoms of a clogged heater core?

If there isn’t warm air coming into your vehicle’s cabin, that would be a possible symptom you have a clogged heater core. However, that isn’t the only indicator you have a clogged heater core. Other indicators would be: 

  • Airflow from the vents is weak or there is no airflow
  • Airflow is cold coming from the vents
  • The floorboard is damp
  • There is the smell of coolant (antifreeze) inside the cabin

Where there is an obvious difference in airflow, it can be the heater core fins are bent or there is a clogged heater core restricting the airflow. The smell of coolant or a wet floorboard usually means the heater core is leaking or there is a hole either in the heater core or a hose connected to the heater core. At this point, the only remedy is to replace the heater core. 

How Do I Know When to Replace a Heater Core?

What happens when a heater core goes out? When the heater core is bad, the coolant isn’t running through the engine as it should, keeping it cool, so a lot of expensive and extensive damage to the engine can happen. So, if you notice any of the following, this could indicate your vehicle has a clogged heater core, or the radiator could have a problem:  

1. Coolant Fluid Leaking Into Floorboard

When there is fluid dripping down from behind the dashboard, that is the worst! Your floorboard is wet, and it smells inside your vehicle.

2. Heating System Not Working 

A broken or clogged heater core will keep the engine heat from transferring to the vehicle heating system to warm the interior. You can diagnose this problem yourself by driving for 20 minutes, then turning the heating system on inside the vehicle.  If the interior doesn’t start getting heat immediately, then you probably have a clogged heater core. 

3. Engine Losing Coolant

A leaking heater core or a  partially blocked heater core will affect the engine’s cooling system. A leaking heater core means the engine isn’t getting the coolant it needs either. Check the radiator for coolant level and if it is low, then there is a leak somewhere in the engine or heating system.

4. Condensation and Fogged Windows 

If there is a clogged heater core, it can’t get hot, and then only cold air will blow through the vents.  If the windows get fogged and steamed up and you can’t get the defroster to clear them, it is a typical indicator of a clogged heater core. If the windows have an excessive amount of condensation, feel the carpeting, and if it is damp the vehicle’s heater core is probably leaking. 

5. Overheated Engine 

While your vehicle’s heating system needs coolant to warm the interior, the engine needs coolant to keep it from overheating. If there is a clogged heater core, it will keep the coolant from flowing through the engine, causing it to overheat.        

How do you unclog a heater core?

There are several maintenance steps your vehicle needs, including flushing the radiator, transmission, and the heater core. The radiator and transmission flushing should be done by a professional mechanic.  The heater core is something you can do yourself, even with minimal mechanical inclination: 

  • Locate the Heater Core: This is found on the vehicle’s firewall and will have two hoses – an inlet and an outlet.  Trace those to the engine.
  • Disconnect the Heater Hoses: Place a bucket under the car then disconnect those hoses from the vehicle’s firewall. There are usually clamps holding them in place that can be removed by squeezing with pliers or loosening screws. Once you disconnect these hoses, you should have water pouring into the bucket. If not, your vehicle either doesn’t have enough coolant and water or you have a clogged heater core. 
  • Apply the Pressure: Connect an air compressor to the outlet house, seal it up with duct tape, and turn the compressor on. Let this “pressurize” the heater core for 10 minutes, and then turn the compressor off. Now, let the system drain into the bucket. 
  • The Water Hose: After everything is drained thoroughly, attach a water hose in the same manner as the air compressor. Turn the water on and it let run through the system 10 to 20 minutes, or maybe longer if your system is dirty. You’ll know when the water starts coming out clear. Now, using the air compressor, blow off the excess water.
  • Reconnect the Hoses: With the flush and pressurizing completed, reconnect the heater hoses using the same clamps and one additional clamp on each for security. 
  • Refill the Coolant: Now add new coolant back into the heater core system through the radiator – a 50:50 ratio of antifreeze and water is recommended. You will need to add some, start the car, and let the fluid get into the system, then add some more. This will ‘burp’ the system, getting all the air out. 

Will a clogged heater core leak?

Yes, and of all the components a vehicle has under the hood and behind the dash, this is the one that will leak inside your car the most.

Can the heater core affect air conditioning?

Not usually – the air conditioning and the heating are two different systems. Your vehicle’s heater relies on the coolant being heated by the engine. The air conditioning, however, uses its own refrigerant.

In Closing

During the winter, while the heater core may seem small, it is a powerful component to your comfort and the operation of your vehicle.  Taking your car in now for “winterizing” is being proactive before winter arrives. This includes flushing the transmission, radiator, and making sure you don’t have a clogged heater core. If you need this kind of help you can reach out to us by calling 847-895-9131.

Car Emissions – What You Need to Know

Busy road with several cars surrounded by car exhaust.

What can cause a car to fail an emissions test?

What happened to the days when we could just get in our cars, start them up and take off without having to worry about car emissions? And for those of us who aren’t sure, what are the emissions of a car anyway? Car emission is what comes out of a car as it is running. Emissions consist of these primary substances: 

  • Nitrogen oxide
  • Non-methane organic gases
  • Carbon monoxide
  • Particulate matter
  • Formaldehyde

What causes car emissions?

Car emissions are the worst contributor to the air pollution problems we have today according to the EPA (Environmental Protection Agency). With that said, what is it that causes these car emissions? The answer is simple – gasoline. Car emissions are explained as simple as that – it is the gasoline you pump into it once a week at the neighborhood gas station that forms the pollution that comes out of the tailpipe. Those same pollutants are escaping from the gas pump too as you gas up your car and as the car engine idles at the signal light. 

How much emission does a car produce?

The average passenger vehicle discharges almost five metric tons of carbon dioxide annually – if it is running properly. With an average fuel economy of just over 20.0 MPG and roads traveled over 11,000 miles a year, each gallon of gasoline in a car will create almost 9,000 grams of CO2. 

Maybe these numbers don’t mean much to you personally. You may be thinking, “I don’t drive 11,000 miles a year,” and maybe you don’t. But many do, and some drive even more. And you’re not the only driver on the road are you? If you were, there wouldn’t be a need for traffic reports at rush hour, or traffic enforcement and wreckers. 

In 2020, the year that we were “quarantined” to our homes, there were still 280 million vehicles on the roadways of America in the 4th quarter. Just for basics, multiply that by 280 million times the 9,000 grams of CO2 discharged in a three-month period. Apparently, not everyone was staying quarantined. 

What happens if your car fails an emissions test?

While there are federal laws about car emissions and testing for them, each state in the country has their own laws that typically follow suit. In Illinois, if your car emissions test fails, it is required to be retested. You’re even given a piece of paper stating that the test showed the car emissions were high and you didn’t get a sticker. 

When this happens, you will have a deadline for getting the problem resolved and the car brought back in for retesting. The State of Illinois provides a limited test extension, during which the garage you visit for your car emission tests will advise you on your next steps.

But what else happens when your vehicle can’t pass the state car emissions testing? Keep the numbers we mentioned above in mind and remember – you’re not the only one on the road. The large amount of gases and solid matter that cars emit are affecting several things, like: 

  • Contributing to global warming
  • Causing acid rain
  • Harming the environment 
  • Harming human health

But maybe this is exaggerated? Or are there facts to back this up? Keep reading and you can make your own conclusion: 

  • Global Warming – Greenhouse gases like carbon dioxide and others are a major part of global warming. Yes, most of the country was buried under snow in early 2021, but there is still proof of global warming everywhere you look. Global warming is affecting farms, nature, sea levels, and wildlife. 
  • Air, Soil and Water – Car emissions and the pollution they create are having a widespread effect on the quality of our air, soil, and water. While the nitrous oxide is a contribution to depleting the ozone layer that protects the Earth from the UV rays of the sun, the sulfur dioxide mixing with nitrogen dioxide is changing our refreshing rainwater to acid rain. That is damaging our buildings, crops, forests, and any vegetation. With oil and fuel spills, even more is seeping into the soil and contaminating the water from our lakes, rivers, streams, and wetlands. Have you noticed your water tasting different over the years? 
  • Human Health – The pollutants from car emissions have a high number of particulate matters that can become airborne, like metals and soot. These are causing eye and skin irritation, aggravating allergies and, as they become lodged in our lungs, more of us are experiencing respiratory problems as well. At ground level, the reactions of hydrocarbons with nitrogen dioxide and sunlight form ozone. While this is beneficial to a point, it can also damage human health by causing breathing difficulties, chest pains, and making us cough more.

What’s Wrong with My AC in My Car?

car ac knob

What does it mean when your car AC blows hot air?

It is only June, but the heatwave of 2021 has started, and now is not the time for anyone’s car air conditioner to quit working!  But then, if it is, getting it to a car ac repair shop now should be a priority, be cause the heat is only going to get worse car ac repair and service shops are just going to get busier. 

The air conditioner in your car is a complex system and if it isn’t blowing cold air, it could be one of these four reasons: 


A car air conditioner needs refrigerant just like the A/C in your home, and if it low or out, then it is going to blow hot air. That refrigerant is like the refrigerant in your HVAC system a liquid that circulates through the A/C system. It contracts and expands as it removes the heat and humidity from inside your car. Without that refrigerant, the other A/C components aren’t able to function.

Why is it leaking? It could be an old hose, a punctured or rusted evaporator. When A/C refrigerant leaks, it doesn’t leave a puddle under your car like an oil leak. The refrigerant, also referred to as freon, evaporates when it is exposed to the air. 

You’ll need a professional car ac repair technician to inspect the system to determine if this is the problem. They do this by injecting a dye into the A/C system which will show them if there is a leak and where, then they are able to repair and recharge the system. 


When a car’s A/C system pulls that heat and humidity out of the car, that refrigerant we mentioned absorbs them. Then, the condenser keeps that refrigerant cool to continue the cooling cycle you know as cold air blowing from the vents. When the condenser isn’t working right, the whole cooling process quits. 

The condenser is located under the hood at the front of your car, usually between the grill and the radiator. The air that flows through the grill help with the cooling and if the condenser has anything blocking it or it becomes clogged, the air can’t the refrigerant cool.

If you have had a fender bender where the grill has been bumped or smashed, the condenser may be broken. Take your car to a car ac repair shop and they can confirm it is the condenser, and install a new one, recharge the system and get your car cooling again. 


The heart of any air conditioning system is the compressor. That is what circulates the refrigerant through the A/C system and if it isn’t circulating the refrigerant, then the condenser isn’t cooling. 

This is a common issue after a long winter where the A/C wasn’t used (who need air conditioning when its 10 below right?). You can prevent this from happening by running your A/C once a month for a few minutes throughout the winter.  Many cars activate the condenser when the defroster is on, so check with your car ac repair shop about your car’s mode of operation. 


When all the components we’ve mentioned here are working, but your  A/C is blowing hot air, then it could be the electrical wiring. Anything from a blown fuse to frayed wiring will keep an A/C system from working as it should.  Your car ac repair technician can evaluate this for you and make any repairs or replacement needed. 

Why do we recommend that you take your car to a car ac repair shop for these issues? Because a professional car ac repair shop will have all the proper tools for car ac repair as well as the experience and knowledge. Remember, the A/C system is a complex system and recharging the refrigerant takes specialized tools and the knowledge to know when it has enough. 

Why did my car AC stop blowing cold air?

When a car air conditioner starts blowing mild cool air or warm air, you’re probably asking yourself, “Why did my car AC suddenly stop working?”.  It can be any number of things, some of which we mentioned above. Any of those things could be damaged, like the condenser we mentioned, or simply just worn out from use.  A few things that and car ac repair technician may find wrong with your car’s A/C could be any of these:

  • The Freon Leaked – a connection, gasket, or hose could be the culprit. 
  • Recharging Needed – all A/C units in cars will loose some freon/refrigerant over time. 
  • Stuck Blend Air Door – a small door that opens/closes the vent system could be stuck closed.
  • The  Compressor Isn’t Engaging – the heart of your car’s A/C system may need to be replaced.
  • Condenser – as we described earlier, where this part is located if vulnerable to getting blocked or broken. 
  • Electrical  – again, mentioned earlier, the wiring could be broken or frayed, or a fuse blown.

What are the symptoms of a bad AC compressor?

The air conditioner compressor in your car is under a lot of stress. It gets turned on, turned off, and these puts a lot of wear and tear on it. After a few years, it can wear it out to where it doesn’t work anymore. A few warning signs that you may need to take your car into a car ac repair shop soon before the compressor is totally gone are: 

  • Strange Sounds: When the air conditioner in your car makes strange sounds, it could be a sealed bearing or a number of the components inside the compressor.  A trained car ac repair technician can diagnose those sounds and determine what is happening, or not happening.
  • Hot Air: When the A/C in your is turned on and blows hot air, this could be the compressor going out.  Again, have a car ac repair technician inspect the system and diagnose the issue. 
  • Fluid Leaking: Anytime your car has fluid leaking, it isn’t good, and that is especially true of the AC compressor. The internal bearings needs that pressurized fluid to work correctly. Your car ac repair technician can determine that is the problem and replace them if possible. 
  • Belt Skipping or Squealing: When your car air conditioning system has a loud squealing sound, it has a belt problem. Take your car to the car ac repair shop before you use the A/C again. 
  • A/C Compressor Clutch Stuck: The clutch on the A/C compress  allows the compressor to work from the engine power, but if that clutch gets stuck or seizes up, then it isn’t getting power. This is definitely something your  car ac repair technician will need to inspect.

Okay, so now you know some possible issues with the A/C system in your car. So, how much does it cost to get air conditioning fixed in a car? The range of  car ac repair costs will vary based on the make and model of your car, and the problem with the A/C. 

General ballpark pricing can range between $200 and as much as $800 or more. When it is the compressor, you can expect that to cost you as much as $1,000 and up.  To have the A/C recharged, that can average between $100 to $150.

Why Does an Engine Stall?

engine stalled on a road

What causes an engine to stall at idle?

Is there anything more nerve raking and worrisome than your car engine stall at the intersection, or in the fast food line?  What is stalling? When a person is stalling, it is usually because we are procrastinating doing something, like washing dishes or filing taxes. When a car engine stalls, this means the car has died. It means you’re not going anywhere until you get it started again. A car engine stall can happen even while you’re going down the road! 

Today, we’re going to answer some questions about Why would an engine stall and what to do when that happen.  Often an engine stall isn’t any major problem, but it could be.  If you know a few things about what causes for a stalled engine, it won’t be as scary if it does happen to you. 

No matter what kind of car you drive, every engine needs 3 key things to operate with a smooth idle:

  • Good air to fuel ratio
  • Sufficient idle speed
  • A strong spark

If a car is lacking any one of these three things, it will stall at an idle. There could be any number of things that cause these three important things not to be working properly.  Some possibilities are the idle air bypass motor, or the idle speed control motor is bad. When these two devices aren’t providing the right idle speed, it can cause the engine to die. Another device that can cause an engine stall is the PCM.

The PCM is the power-train control module, which is a control unit. It works with two other devices: ECU (engine control unit) and the TCU (transmission control unit). If any of these three are working in conjunction with each other, it can cause an engine stall.

What causes rough idle and stalling?

There can several reasons why a car engine is idling rough. Those reasons could be something minor or major, if the engine stalls while idling rough, it could be a bigger problem. In either situation, it isn’t just something annoying and inconvenient and the car should be inspected by a professional mechanic.   Some of the most common reasons for a rough idling and engine stall are: 

  • Fuel Injectors: The fuel injectors could be dirty and not mixing the air and fuel right, cutting back on the amount of fuel is getting to the engine. 
  • Idle Speed:  The idle speed on a car is typically between 600 to 1,000 RPMs. A car that has a rough idle may be the speed setting is incorrect. A professional mechanic can reset this for you. 
  • Vacuum System: Every car has a vacuum system and if it develops a leak, the computer isn’t able to regulate the ratio of the air and fuel mixture, leading to a rough idle and possible engine stall. 
  • Spark Plugs: Spark plugs create the spark that allows a car’s engine to bur the fuel. When they are damaged or have been installed improperly, it can case the car to idle rough.  
  • Fuel Pump: Fuel delivery problems can cause a rough idling car. If the fuel pump is clogged or about to go out, it can’t get the fuel where it needs to be. The car will idle rough and the engine stalls. 
  • Fuel Filter:  Just like the fuel pump, if the fuel filter becomes clogged, it will cause a rough idle and engine stall too.
  • Electrical Components: A car has several electrical components and if any of them fail or are having problems, you can get a rough idle or the engine stalls. The electrical components include the spark plugs, plug wires, coil, or the ignition module.  
  • Airflow Sensor: If the airflow sensor goes bad, it can cause a rough idle because the engine can’t get the right amount of air the computer is telling it needs. This can also lead to an engine stall.
  • Oxygen Sensor:  The oxygen sensor measures if the gas is lean or rich and tells the computer ow to adjust the ratio to the air. When oxygen sensor is bad or dirty, it isn’t sending the right signal to the computer and causes the car to idle roughly and can cause the engine stall.

Why does my car stall when I stop?

An engine stall while a car is stopped could be the air to fuel ration, the fuel not pumping, or something electronic. A common reason why this happens is because there isn’t enough fuel getting to the engine to keep it running while stopped. What should I do if my engine stalls?

burst engine smoking

Is stalling bad for the engine?

Manual shift cars are known more for experiencing an engine stall, but automatic shift cars will stall too.  In the case of a manual shift car, it is usually because you didn’t engage the clutch. Simply restart your car and you’ll be on your way in most cases.  In the case of an automatic shift car, you’ll notice the engine stall when your power steering quits, then the power brakes won’t work. At this point, do your best to coast to a safe place off the road, turn on the hazard flashers and try to restart the engine. If it won’t start, call for help. 

Should you have any of these issues of engine stalling with your car, keep your safety in mind first.  Then get your car to a professional mechanic that will know how to fix a stalled engine. The sooner the better because while it may be a small issue know, ignoring it could allow that small issue turn into something bigger and more expensive.

What are the 7 fluids in a car?

car fluid inspection

The different kinds of car fluids

Well that could be a surprise to a lot of folks!  Who knew there were 7 different car fluids?!  Even the most non-car person will know there is gas and oil, right? What other car fluids are there?  

For the person that isn’t mechanically inclined, it can be confusing and difficult to know which car fluids is which, what it looks like, and where it goes. Here we provide the following list with their general colors so that when you have car fluid leak, colors tell you which fluid is leaking. 

  • Motor Oil: Even for the least mechanical person, basic knowledge tells you that a motor needs lubricating. Low oil levels can be detrimental for your car, so keeping it checked is important. Motor oil is typically a dark brown to black in color, with the black being the worse of the two, meaning it is burnt or dirty.
  • Radiator Fluid: This fluid is found in the radiator and inside the engine. From your perspective, you can only see what is the in radiator, and this is what keeps your engine running without overheating. Radiator fluid is generally green in color and has a sweet like smell, there are newer types of radiator fluid that are red. 
  • Transmission Fluid: The transmission is an important part of what makes a car move and it needs fluid designed for transmissions, it works the same way engine oil works for the motor. Transmission fluid is typically reddish in color. 
  • Power Steering Fluid: A car with power steering needs fluid to lubricate the power steering system for smooth turning operation. Power steering fluid is reddish in color. 
  • Brake Fluid: The braking system in a car is operated by hydraulics and fluid is needed for that hydraulic system to work smoothly. Brake fluid should be a clear-yellowish color, if it is any darker, then you should have a mechanic check your braking system.
  • Air Conditioning Coolant: The coolant in your air conditioning is like an oil that keeps it running smoothly and cooling your car. Over time, it can dissipate, and your air won’t be as cool as it should, even though it is blowing air. It is a clear gas like substance but can be detected with ultraviolet light and appear yellowish. 
  • Windshield Washer Fluid: This may be the last fluid you think of for your car, but it is important because it keeps a clear visibility.  Most windshield washer fluids are blue, there are some pink colored one that include a freon to keep the water from freezing up. When you see blue car fluid leaking, it is probably the reservoir for the windshield washer fluid. 

Is power steering fluid and transmission fluid the same?

In some ways, yes.  Both automatic transmission fluid and power steering fluid are hydraulic car fluids. Automatic Transmission Fluid can be used for power steering fluid, but not the other way around. pump. However, you should check the manual that comes with your car and read the manufacturer’s specifications. Some cars must have automatic transmission fluid and a substitute won’t work. 

What fluid levels should I check in my car?

Each car is different and each fluid in every car is different. The standard schedule for an oil change is every 3,000 to 5,000 miles, however, you need to check the oil more frequently.  Depending on the age of your car, a weekly oil check is sufficient, you could go 10 to 14 days in between oil checks. 

Make sure your car is parked on a level area and only when the motor is cold. Checking the oil while the motor is warm will give you an inaccurate reading. The brake fluid and power steering fluid should be checked while the car is parked on a level area too. When checking the transmission fluid, leave the engine running and have the transmission in neutral. Checking both of these once a month or as recommended by the manufacturer. 

Most auto shops that do oil changes will check all the fluids for you while they have your car. The windshield washer fluid is one that you’ll need to check periodically and add more fluid based on how much you use the wiper system. 

Is it oil or transmission fluid leaking?

Any type of puddle under your car is a sign that your car needs mechanical attention. How quickly it needs it depends on what the leak is from and how bad it is leaking. 

With an oil leak, it generally will not create a puddle under your car, but if it does, do not drive it, call your mechanic. Oil leaks tend to be more of a drip or seepage, and it takes a good amount before it leaves a puddle or spot under the car, then it will be a brownish color in most cases. In a car that has engine problems, the oil could be black. 

A transmission leak can be fairly simple to diagnose by the location of the leak. The fluid is a distinct reddish color to a brownish color. If you aren’t sure it’s the transmission, move your car and place a piece of cardboard or paper where you park. After driving your car for a bit (go to work and back), park over the cardboard or paper. If there is a reddish spot or stain on that paper, you have a transmission leak. 

If you have a car leaking fluid and smoking, where the smoke is coming from is a general idea of what fluid is leaking. Oil leaks will usually have smoke coming from the exhaust area or under the hood.  Oil is one car fluid you’ll know the smell when it leaks. There are car fluids on the market you can add to the oil or transmission that is a stop leak fluid for cars as a temporary fix. 

What color is transmission fluid when it leaks?

A transmission car fluid leak is going to be a reddish brown in color with a thin layer of fluid on top or a  thicker brown layer on top.          

oil change

How do I change the fluid in my car?

The oil and transmission will require you to have your car on a level area and drain the car fluid that is in the car now by removing the oil pan or transmission pan, then remove the oil or transmission filter.  Clean the pan edges off and apply new gasket or sealant on the clean surface.  Replace the filter then replace the pan. Next, add oil or transmission fluid in the amount recommended by the manufacturer. 

For changing brake fluid, simply empty the reservoir, clean out with a rag and add the new brake fluid. There isn’t a screen or pan to remove as there is with oil and transmission fluid changes.  Same is to be said of windshield washer fluid, although that isn’t one of the car fluids that needs to be changes. 

For the radiator fluid, you’ll pull the drain plug out on the bottom of the radiator and allow all the water and antifreeze to run out. When it is emptied, replace the drain plug, and add half and half water to antifreeze or antifreeze that is 50/50. 

When it comes to your car fluids, they each are important and play a significant role in how your car performs. Car fluids like the transmission can cause your car to stall at the worst possible time and car fluids like the oil are important to keep your motor in good condition.  Finding a mechanic you can trust is essential for car ownership.

What is factory scheduled maintenance?

scheduled maintenance light

Upkeep on your vehicle

A new vehicle isn’t cheap these days, even the bottom line of all makes is going to cost you upwards of $5,000. However, one thing they all come within different levels is a factory vehicle warranty and factory vehicle maintenance. The factory vehicle warranty is what comes from the vehicle manufacturer providing you their guarantee that if anything breaks or goes out within a certain time, the dealership will repair or replace it at no charge to you. 

What is the basic maintenance of a vehicle?

The basic factory maintenance can vary from manufacturers to manufacturer, but the overall goal is to keep the vehicle you purchased in top condition. This is done by checking the important components and systems of the vehicle so that it is operating at an optimum level safely. The first scheduled factory vehicle maintenance is usually between 7,500 miles and 10,000 miles. Some manufacturers will suggest the first factory vehicle maintenance at 100,000 miles.  The mileage will vary between manufacturers and the model of the vehicle. 

After the first factory vehicle maintenance, How often should vehicle maintenance be done? Depending on the make and model, the frequency is typically measured by the mileage and can vary on the make and model of the vehicle. The mileage could be anywhere between 5,000 and 10,000 miles, with a few car manufacturers stating 100,000 miles. Other vehicle manufacturers recommend every 6 months. 

What is the basic maintenance of a vehicle?

During a factory vehicle maintenance appointment, the technician will have a factory vehicle maintenance checklist to assure they check the important things such as: 

  • Lights – headlights, brake, and taillights, turn indicator lights
  • Steering
  • Brakes
  • Tires

These are things that provide safety for you, your passengers, and others while driving the vehicle. Some factory  vehicle maintenance appointments will include the following on their checklist:  

  • Coolant Level
  • Oil Level and Oil Filter
  • Air Filter
  • Cabin Filter
  • Tire Pressure

Most vehicle dealerships will include a free car wash and vacuum of the vehicle and offer an upgrade at your expense for an interior detail and exterior wax while you’re there for your factory vehicle maintenance appointment.  They may also offer or recommend that you follow up soon with tire rotation and other vehicle maintenance matters not covered under the factory vehicle maintenance plan. 

Should I take my car to the dealer for scheduled maintenance?

When you purchase a new car, depending on the make and model, there can be several bells and whistles included in the purchase, like factory vehicle maintenance. Do you need to return to the dealership for your factory maintenance and repair though? What if they aren’t close by and you can’t find a time that is convenient? 

In short, no, it isn’t a law to return to the original dealership for your basic factory vehicle maintenance. The regular maintenance you do for any car, new or old, like oil change and tire rotation, can be done at your local mechanic’s shop. You don’t even have to return to that specific dealership for warranty work. 

Yes a vehicle manufacturer’s sponsored dealership is supposed to honor a vehicle warranty irrespective of where the factory vehicle maintenance is completed. However, yes, there is a however to this question. Like anything else, the dealership can find a reason to void that warranty and not acknowledge the factory vehicle maintenance or warranty work was done correctly or by the recommended schedule. 

This becomes a matter of you said – they said and if they don’t have documentation within their files, it doesn’t exist. You can combat this by keeping every receipt of every type of work you have done on your vehicle. Such going to your regular mechanic for an oil change, fluid flush, tire rotation, or other basic maintenance while your vehicle is still under warranty. With your receipts in hand, should the dealership or the sponsoring vehicle manufacturer deny any type of warranty with a service issue, you have proof it was done according to the manufacturer’s factory vehicle maintenance recommendations and requirements.

This includes any warranty work. For example, you’re traveling out of state when your vehicle has a warranty issue. Getting the vehicle back to the original dealership may not be possible, so get your car to a dealership for that model is recommended. Or to a certified mechanic for that make of vehicle. Any receipt for warranty or basic factory vehicle maintenance work should have the vehicle details stated, the date of the work, and detailed description of what was done by the mechanic.

Should I do my own car maintenance?

Again, this is your vehicle and by law, a dealership or manufacturer cannot tell you not to do your own recommended factory vehicle maintenance, and in most cases, especially if you have experience in working on vehicles, you’ll be okay. This is especially true for things like the  brake fluid, oil, power steering fluid, transmission fluid, coolant, tire rotation, etc. 

Then there is the “however” factor again. By doing this work yourself, no matter how meticulous you may be with the work and the materials used, you won’t be using the factory maintenance tools nor will you have any proof of the work done like a detailed receipt. You may have a receipt for the purchase of the oil and other products used, but not that the work was done.  Taking your car to a manufacturer’s approved and the sponsored dealership is always the better option. 

Vehicles today can come with an awesome warranty level. Gone are the days of the basic 10,000 mile warranty, vehicle manufacturers now offer 50,000 to 100,000 mile warranty. Some are extensive warranty, others are basic. 

Still, cars do wear out over time with things breaking down. If you keep your car that long, what should you replace at 100k miles? You should have been doing the following all along, not waiting for the 100,000 mile mark: 

  • Oil and filter change
  • Coolant and transmission flush
  • Checking brake and power steering fluid.

At the 100,000 mile mark, have your mechanic check the following and replace as needed, if they haven’t been already within the last 10,000 miles: 

  • Timing belt
  • Water pump 
  • Brakes and rotors 
  • Tire tread, air pressure, rotate if needed
  • Wheel alignment 

Your vehicle may not be as big of investment at your home, but it is an investment. The better you take care of it, the longer it will last you. Call 847-895-9131 today for your scheduled maintenance in Schaumburg, IL.
