How engine cooling system works

coolant cap

Why engine cooling is necessary?

For a car to operate, we know it needs an engine and transmission, among a host of other components. The engine is a combustion engine that needs certain things to make it work, one of which is the engine cooling system. This works with a fluid referred to as engine coolant, which can be plain water, but usually has antifreeze mixed in with the water.

Internal combustion engines produce a sizeable amount of heat which causes the engine components to expand by a certain amount as determined by design and engineering. Having a process to cool the engine, the engine cooling system, keeps that expansion within that certain amount as they designed it, staying within the tolerance range set with the engineering of the design. There are two distinct ways a car engine is cooled. 

What are the two types of cooling systems?

The two types of engine cooling system of cars are: 

  • Liquid Cooling – this system circulates coolant and water through hoses and pipes inside the engine. The coolant and water pass through the hot engine, absorbing the heat generated and cools the engine. The coolant and water go from the engine and goes through the radiator. Then the heat from the coolant and water is transferred to the air that then blows through the exchanger. 
  • Air Cooling – they used this system on older model of cars, and today, there are a select few that use it today. These type of cars operate with an engine cooling without radiator instead of circulating coolant and water through the engine. There are aluminum fins covering the engine block that pull the heat away and a powerful fan forces the air over the fins, cooling the engine by moving the heat to the air. 

For this article, we will focus on engine cooling system that is liquid-cooled. 

Why do you need an engine cooling system?

The prime purpose of engine cooling system is to transfer heat to prevent damaging the engine from the coolant and water boiling and freezing.  If the coolant reaches a boiling point, vapors form, and the heat isn’t transferred properly, allowing the engine metal to heat up to appoint that it could melt. The liquid serves as engine cooling and lubrication for the metal and non-metallic components of the engine and the engine cooling system. 

How is an engine cooled?

There are three vital functions of a car’s cooling system within six key parts.  The three vital functions are: 

  • Removing excess heat from the engine
  • Get the engine at the ideal operating temperature
  • Maintain an efficient operating temperature 

Those vital functions are achieved by using these six key engine parts: 

  • The engine
  • The radiator
  • The water pump
  • The cooling fan
  • The hoses
  • The thermostat 

If you have ever been stuck in traffic on a scorching summer day and have your car overheat, you got a surprise lesson on the importance of an engine cooling system. The following process keeps the engine at the optimum temperature for expanding at that designed and engineered tolerance that we mentioned earlier. 

For the combustion process of an engine cooling system, part of the fuel energy is transformed into heat, which is transmitted to the coolant. The water pump then circulates that coolant through the engine, through hoses that transport the heated coolant to the radiator. There, the heat changes into air and cools it, then pulls that air past the engine. The coolant is returned back to the water pump, and it is recirculated.

How do you diagnose a cooling system? 

Coolant is important to maintain an engine’s temperature. If the engine cooling system doesn’t have any coolant, what happens? The following is likely to happen:

  1. Temperature gauge rises, and warning lights go off.
  2. Engine will shut down on newer cars.
  3. Engine parts are damaged if the car doesn’t have the engine shut down feature. The parts that overheating can affect are cylinder head, piston timing, head gasket, water pump, and bent or warped rods.
  4. Other potential issues resulting from theengine cooling system not having any or enough coolant include steam coming from under the hood and/or out the tailpipe, the hood gets extremely hot, and the inside of the car heats. 

When a newer car runs out of coolant, it won’t cause damage instantly, but if you keep driving it after the gauge indicates the engine is hot, that will damage it. Many new cars today will go into ‘limp mode’ and you can get to a safe place, but it shouldn’t be driven on the roadways in that mode for a long distance. 

How Do You Know Your Car Needs Coolant?

The engine cooling system will give you warning signs before it gets damaged. It is up to the driver of the car to realize the warning signs and get the problem addressed. The common warning signs are: 

  • The temperature gauge creeps upward, or a heat light comes on
  • Car is blowing hot air even with the AC on 
  • Car is using an excessive amount of gas 
  • You notice a sweet odor coming from the car 

As you read this article, you may be asking “How can I cool my car engine?” and for the non-mechanic person, we suggest the following:

  1. Turn the air conditioner off.
  2. Turn the heater on.
  3. Put the car in neutral or park and rev the engine.
  4. Park the car if you’re driving and open the hood.

It takes a car at least thirty minutes for the engine to cool down. After that, you can open the radiator with caution, and add coolant if needed. The best thing you can do is call a professional towing service to get the car and take it to your mechanic to check your car’s engine cooling system and advise you from there the next step.

What Could Cause the Check Engine Light to Come On?

A Check Engine Light

What could cause the check engine light to come on?

When you see the orange-yellow engine block pop up on your car’s dash, it may not be a reason to panic, but it does mean there is a problem with your vehicle’s emission system. Often the problem requires you to get a diagnostic run on the car’s computer to discover what’s causing the check engine light to come on. Some possibilities include:

  • A loose gas cap: Tighten the gas cap to prevent air from seeping in or replace the cap if it’s missing.
  • Faulty oxygen sensor: An oxygen sensor will need to be replaced. 
  • Faulty spark plugs or ignition coils: The plugs, wires, or ignition coils may need to be replaced.
  • Catalytic converter has gone bad: The catalytic converter needs to be replaced. Usually, if the catalytic converter is bad the check engine light will blink consistently. If this happens, pull over and have your vehicle towed to an automotive shop.
  • Bad mass air flow sensor: The sensor will need to be replaced.

When you have a check engine light come on in Schaumburg, IL, you’ll want to get the problem diagnosed and repaired. For quality emissions service, count on the experienced team at Express Auto Repair & Emissions. Book a service appointment by calling 847-895-9131

What does check engine light look like

In most vehicles, the check engine light will be yellow-orange and look like an engine. On some cars, the light will simply say “Check Engine,” or “Service Engine Soon”. Warning lights will vary on each vehicle.

Is it safe to drive your car with the check engine light on?

Whether it’s safe to drive with the check engine light on or not will depend on what the problem with the vehicle is. If the light is steady, this means there is a minor fault in the vehicle’s emissions. In most cases, it is OK to continue to drive the vehicle, as long as other systems like the brakes and lights are working, although you may notice your vehicle will use more gas in some instances. If other dashboard lights come on, you will want to take the car in as soon as possible. 

If your check engine light flashes or blinks, this is a sign of a serious problem, usually a faulty catalytic converter. You will want to get the car to a mechanic immediately. It’s best to pull the vehicle over and have it towed to an auto shop. A bad catalytic converter can overheat and even catch fire. 

What do you do when the check engine light comes on?

Whether the check engine light is steady or flashing, the most important thing to do is not panic. If the light is flashing, however, you do want to pull the vehicle over and have it towed to the nearest shop. But, because the light can mean different things, you should take it in as soon as possible to run a diagnostic, or run a diagnostic yourself if you have a scanner available. The test will show what code is causing the light to come on. You can make decisions about repairs after that. Even if it is a loose gas cap that causes the light to turn on, a diagnostic is always a wise choice to ensure that is the problem.

How do you check a check engine light?

When the check engine light comes on, to determine what’s wrong with your vehicle, you will need to have a diagnostic test run on it. You can purchase various scanners and run the diagnostic yourself or you can take the vehicle to an auto repair shop and have them run the test. Usually, the scanners a mechanic will have will be more detailed than one you purchase yourself. 

Can check engine light mean nothing

Rarely, if ever, will a check engine warning pop up for no reason. Of course, when the light comes on, it doesn’t necessarily mean there is a mechanical failure. It could simply mean your gas cap is loose and needs to be tightened. If you’ve already tightened your gas cap and the light is still on, bring it in to Express Auto Repair & Emissions and we’ll run a diagnostic on it.

Can low oil cause the check engine light to come on?

Low oil pressure is one possible reason why the check engine warning has come on. If there is a low oil pressure problem, the oil warning light normally will also come on. The oil pump could be damaged or the oil was changed improperly and air is circulating through the system.

Will check engine light come on for bad fuel pump

A faulty fuel pump may also cause your check engine warning to come on. As with other possibilities, a diagnostic test can determine if the fuel pump is the problem.

Why Oil Change is Important

Closeup engine oil cap in engine room at modern car. Interior of car.

Learn More About an Oil Change

Each car will have specific maintenance checks that need to be provided every now and then. According to your owner’s manual and condition of your car, there will be guidelines on when to impart certain services such as an oil change for your vehicle. It’s especially important that an oil change is handled in a timely manner as essentially this is what makes your car operate smoothly, without enough oil you can see parts age prematurely and performance issues emerge. As with any car service, make sure to confer with a professional mechanic to see what can be done to help your car. Until then, here is some basic background information concerning an oil change that can prove useful to you.

What happens if you go too long without an oil change?

If you go long enough without an oil change eventually you can experience complete engine failure. When it’s been so long that oil turns into sludge that means it will no longer draw heat away from the engine. This can mean that the engine can eventually overheat enough to seize up or blow a gasket.

What color oil is bad?

Although oil can be very dark or blackened it can still work well. However, with new and clean oil you’ll have an amber color. With engine oil becoming darker this can point towards contaminants being present, high heat, or additives that caused the oil to darken after normal use.

Does low oil affect acceleration?

Low oil won’t provide as much lubrication for mechanical parts to move and operate smoothly. Therefore you may have more sluggish acceleration with your car as well as the feeling that the engine is down on power.

Will your car shake if you need an oil change?

If you require an oil change, the high level of friction of your car’s engine without lubrication can affect the quality of the ride. More specifically, you’ll feel abnormal shaking and vibrations when your car is idling. If you find our car is close to really needing an oil change try to not have your car idle too much until you can get it fixed.

How do you know when your car needs an oil change?

  • The check engine and/or oil change light is glowing
  • There’s a knocking noise or other noise coming from the engine.
  • You smell oil inside the car.
  • You notice dirty and dark oil.
  • There’s exhaust smoke emitting from your hood or inside your car.
  • Mileage is an excessive amount.

What oil change do I need?

With cars that require conventional oil, it’s recommended to have an oil change every 3,000-5,000 miles to maintain mechanics. Although some synthetic oils can last from 10,000-15,000 miles it’s usually a good idea to change it every 7,500 miles.

How often do you really need to change your oil?

An oil change is typically recommended to occur every three months or 3,000 miles whichever comes first. Yet other car models may implement it at even 7,500-10,000 miles later. Ultimately it will depend on the age and make of your vehicle, your driving habits and the type of oil that you use.

How much should an oil change cost?

An oil change can cost anywhere on a minimum of $20-$25 and at most $50-$55. 

Change Oil or Filter

If you’re wondering whether you need an oil change or filter change it’s best to consider the age of your filter. Many car manufactures will usually suggest that you change your oil filter every other time that you have your oil changed while parts and oil manufacturers say to replace it every time you get new oil. 

Will my car run better after an oil change?

An oil change will provide a lot of noticeable benefits such as improving the gas mileage of your car when oil changes are done regularly. Better lubrication of your car between metal parts will increase the engine’s performance and will have it not use as much gas since it will work more efficiently.

Contact Your Local Auto Service Company to Schedule An Appointment

When you require an oil change service it’s best to rely on your local auto repair service company to do the task. Only a professional will be able to provide an inspection as well as other services that may need to be implemented in order to comply with what’s needed for smoother vehicle operations.

How often do you need to rotate your tires?

car with tires properly rotated on the road

Rotation for longer-lasting tires

Car tires are an important part of a vehicle, obviously, because, without them, it couldn’t go anywhere. You have to more than just put tires on your vehicle though, you must take care of the tires for safety and so you get a longer life span from them.

A common maintenance step that many vehicle owners do is get a tire rotation and alignment for their car tires from time to time, or tire rotation with an oil change. We need both combinations to keep a vehicle in good condition and safe.

Are tire rotations important?

Your vehicle is an important and substantial investment, so taking care of it is important to keep it is in running condition and protect the value of it. This includes scheduled maintenance like oil change, fluid check, properly working brakes, making sure the car tires are properly inflated, getting new tires when needed, and tire rotation in between new tire purchases.  

What good does it to have car tires properly inflated or what good does a tire rotation to do for the car? Car tires that are regularly serviced, including make sure they have the right amount of air pressure and having them rotated will give you the maximum tread life and keep your car driving and riding better. Properly inflated and rotated car tires will give you the best performance of your vehicle and maintain its value for future trade-in or for selling.

Your owner’s manual that comes with your vehicle will have a recommended maintenance schedule for car tires, including the rotation service. If you purchased a used car and the owner’s manual isn’t available, the tire manufacturer will have their recommendation or ask your mechanic.

The patter that car tires are rotated is important too. The front axle of the car has a different job than the rear axle, and those jobs create wear on car tires. That tire wear effects a car’s performance, which will wear them out faster, the car uses more gas, and can also affect the safety of a car.

 Do you really have to rotate your tires?

Yes, it is not an upsell of the car dealership or your mechanic. If you think about it for a moment, the car manufacturers and the tire manufacturers will have their guide and recommendation of how often rotating car tires should be done. They both have already sold you their product, right? So, why would they recommend car tires be rotated if they’re not making money from the service?

The usual recommendation to rotate car tires is every 5,000 miles to 10,000 miles. Some cars and some car tires will have a different recommendation, and you may have a personal preference. The number one reason for rotating car tires is for wear and tear to equalize because the front tires typically wear out faster than the rear tires. This is because the outer side of the front car tires takes more pressure when you make turns, especially for parallel parking, three-point turns, and U-turns.

What happens if you don’t rotate your tires?

Good car tires are important for a comfortable ride and as a guarantee for safe traveling. Between you and the road are your car tires and if they are inferior quality or condition, your car’s performance is diminished, as is your safety.

There are several benefits to be had from rotating your car tires, with the main ones being:

  • It preserves your car’s balance, making turns is safe
  • It helps with maneuverability and traction, keeps your car on the road
  • It preserves the tire tread giving you longer tire life expectancy

Tire manufacturers offer a guarantee on their tires and the mileage you can expect from them under normal driving conditions. Having your car tires rotated on a regular basis will give you a better chance of keeping that guarantee held. The main functions of your car tires are:

  • To support your car’s bulk weight
  • To absorb the irregularities of the roadways
  • To provide traction and braking so that you drive safely and come to a safe stop
  • To make your turns safe and smooth

Which way do you rotate your tires?

It depends on whether your car tires are directional or non-directional. With directional car tires, the tread pattern is one-way and optimized for the direction the tires rotate – they are specifically made for either the left side or right side and most tires will have either an arrow or a triangle on each tire’s sidewall indicating the direction it should turn. To rotate directional car tires, exchange the right front tire with the right-back tire and the left front tire with the left-back tire:

With non-directional car tires, the tread pattern is designed so we can mount them on any car wheel. To rotate non-directional car tires, use the crisscross pattern. For rear-wheel-drive cars, move the front tires to the rear on opposite sides, such as front left-to-right rear and front right to left rear.

Can you rotate tires too often?

The basic recommendation for car tires to be rotated is every 6 months or every 10,000 miles, unless you drive less than 7,500 miles annually, which usually coincides with oil changes and can be done at the same time. Some cars the manufacturers recommend the oil change every 15,000 miles, and in that case, you’ll want to get your car tires rotated in between oil changes. The owner’s manual that comes with your car may have different recommendations, and if so, that is the schedule you should follow. Just as your home needs regular scheduled maintenance and check-ups on the HVAC system and roofing, your car needs regularly scheduled maintenance. Your home protects you and your family. Your car does, and is for many people, the main mode of transportation to and from school, work, and more. With that in mind, the importance of things like the oil change and rotation of car tires is obvious. Call 847-895-9131 today for your tire rotation in Schaumburg, IL.

What Is Heater Core In Car?

Inside of Car Air Vent

Learn More About A Heater Core

There are many parts to a car yet for comfortability purposes perhaps the most important area of operations will be with the heating and cooling system. With winter approaching fast it may be time to check up on the heating functions of your car. Essentially, the part of your heater that is most important will be the heater core. Here is where heat will be allowed to disperse throughout your car keeping occupants and drivers warm and crisp. However, like all parts of your vehicle, it may require maintenance or repairs from time to time. When you’re in need of a professional to check out your heater core be sure to get in touch with your local car shop. Here is some background information about heater cores that may prove useful to you in the meantime.

What does heater core look like?

A heater core is a part of a car’s cooling system and looks like a miniature version of a radiator with a grid of little tubes and a waffle-like appearance from the fins that send heat to the rest of the car through vents.

What does a heater core do?

A heater core will disperse the heat throughout the car with the cooling system and will allow your heater and defroster to work. The primary purpose of the heater core is to heat the cabin of the car.

How does my car’s heater core work?

The heater core of a car will work much like the radiator does yet instead of cooling the motor the heat form the coolant will warm the car’s interior. Basically, it will divert the coolant from the rest of the car’s cooling system to heat the interior of your car.

What happens when a heater core goes bad?

Your heater core can exhibit many signs when it starts to go bad, one such sign can be when the inside your car fogs up with condensation. What this usually points to is a leak from the coolant vapor that goes into the cabin of a car when the car heats up as you start driving.

Can I drive my car with a bad heater core?

Usually, a bad heater core will go bad after leaking. This can occur when the heater core uses the engine’s coolant to make heat. With a leak, the amount of coolant to cool the system will be lowered which results in a higher temperature of parts which can ultimately damage the engine of the car.


Car Heater Button

How do you test a heater core? 

  • Turn on the engine to see that heater works.
  • Check the radiator for coolant.
  • Make sure the thermostat is correct.
  • After the engine has been running for a minute or so see if your smell antifreeze in the air coming from the vents. (Faulty heater core)
  • See if small puffs of smoke come out of vents. (Faulty heater core.)
  • Feel the hose of the heater core. (If one is warm while the other is cold, there’s a faulty heater core.)

Can heater core cause leak?

A heating core can leak even in older vehicle models where the heater core is outside of the cabin. It can find it’s way into the cabin and into ventilation ducts which can cause problems down the line.

Can a heater core be flushed?

A heater core can be flushed from the vehicle’s firewall by loosening the clamps and disconnecting the heater hose. Essentially, somewhere along the process of the mamy steps of the flushing method, your system will then be filled with water 1-2 times to flush out the remaining coolant.

How much does it cost to flush a heater core?

A heater core flush service will cost around & $79-$89. Flushing the tubes of the heater core can allow for the coolant to flow more smoothly especially if the heater wasn’t working as well as it usually would.

What does it cost to replace a heater core?

A heater core will cost around $564-$927 for labor and parts. Since the location of the heater core is variable you can see costs being higher for labor. The part itself will actually cost around $80-$234.

How Do I Take Care of My Car in Hot Weather?

A Car Driving Down a Sunny Lane.

How do I prepare my car for summer?

Each season has its challenges when it comes to car care, winter and summer especially, and you’ll want to prepare your vehicle for both. Here, we’ll concentrate on summer maintenance for your car. On your summer car maintenance checklist, you’ll be primarily concerned with your tires, your engine, and keeping your car cool inside and out. Below, are the Top 10 things to put on your “My summer car maintenance” checklist.

Top 10 car summer maintenance tips:

  • Check your coolant: As temperatures soar, so can the heat generated by your engine. Ensure there’s plenty of coolant to prevent the engine from overheating.
  • Check engine belts and hoses: Make sure all of your engine’s belts and hoses are in good shape and secure. Any cracked or worn belts or hoses should be replaced.
  • Check your wipers: While it may rain less in the summer, you need to be prepared for it by making sure your windshield wipers are in good condition. Wipers that are in poor condition can leave streaks over your windshield that may affect your vision. 
  • Check fluid levels: Keep up with your regular oil changes and check other essential fluids like brake fluid, washer fluid, and power-steering fluid. 
  • Check the air conditioning system: Have your air conditioner checked out, and make sure there is enough refrigerant in the system.
  • Check the air filter: Make sure your air filter isn’t clogged with debris. The air filter needs to be changed regularly.
  • Check the tires: You want to make sure your tires are inflated properly and the treads are not worn or cracked. Check for nails or items that could create punctures in the tires.
  • Check the battery: Make sure your battery is securely mounted, and that the terminals and cables are clean and clear of corrosive build-up. Have the battery tested. Extremes of heat and cold can affect the charge.
  • Keep the car clean: Washing the car regularly not only makes it shine, it protects the paint from the sun’s rays. Waxing the car will protect it further.
  • Keep an emergency kit on hand: In case you do have a breakdown, keep an emergency kit on hand that has items like jumper cables, a flashlight with extra batteries, road flares, basic hand tools, a first aid kit, as well as water and non-perishable food.

Along with summer maintenance for your car, make sure to keep up with any preventative maintenance including your factory scheduled maintenance. For the best in car care in Schaumburg, IL, schedule your maintenance services with Express Auto Repair & Emissions by calling 847-895-9131.

How can I protect my car in the summer?

Along with basic summer maintenance for your car, you’ll want to make sure your car is protected from the summer’s heat. One of the best ways to protect your car from heat and harsh sunlight when you are at home is to park it inside your garage or under a covered space. When you are out, try to park it in the shade if at all possible. If can’t park your car in the shade or under a covered space, use sunscreens to cover the interior of the car. Not only will the screen be useful to prevent heat damage to the dash, the steering wheel and other parts of the interior, you’ll be protected from the heat when touching them. Tinted windows are also useful to help keep the heat out.

How do I take care of my car?

While we’ve been concerned with summer maintenance for your car, no matter what season it is, regular maintenance will keep your car in good condition for as long as you drive it. You may ask, What is preventative maintenance on a car? or How do you do preventive maintenance on a car? Keeping your car regularly maintained is generally pretty easy. For the best preventative maintenance, you should follow the maintenance schedule in your owner’s manual. While maintenance schedules will vary depending on the make and model of the vehicle, in general, if you follow these car care maintenance tips, you’ll be on your way to good car care:

  • Get an oil change every 5,000 miles, and check oil levels regularly: While many dealerships or service shops will recommend an oil change every 3,000 miles, most modern engines are generally good for 5,000 miles. You also want to check the oil levels regularly to ensure you have enough oil.  
  • Change the air filter every 10,000 miles: A clean air filter will improve fuel efficiency, prolong engine life, and lower emissions.
  • Rotate the tires every 5,000 to 10,000: Rotating the tires regularly prevents them from wearing out too soon.
  • Wash your car regularly and keep the windshield clean: Washing your car helps protect it from the sun, as well as damage from dirt, grime, as well as the acidity of bird droppings.
  • Check the tire pressure regularly: Driving on underinflated tires can be dangerous, and causes your tires to wear out faster.

When it comes to summer maintenance for your car or regular preventative maintenance, it’s essential to protect your engine from wear and tear. Serious damage or prolonged negligence and wear could require engine rebuilding

What is Coolant System Service?

Hands Pouring Blue Antifreeze Liquid In Car

Avoid Cooling System Repair

How cooling system works in a car involves the use of coolant or antifreeze which prevents boiling points and freezing temperatures in your car which can affect the parts of your system from performance and overheating. It also works with your heating and cooling and can regulate cabin temperatures for comfort as well. It’s important to realize that the cooling system in automobile differs than that with your home or business and have more limited capabilities in comparison. Yet to be fair in that regard it does do the basic job of proving comfort. In order to maintain the performance and integrity of your car’s engine and system, it’s important to stay on top of your coolant levels and vehicle’s standard maintenance requirements so you can avoid the headache of cooling system repair. Here is some information regarding your cooling system that may be of help for your vehicle’s longevity.

Cooling System vs Air Conditioning

A cooling system involves the cooling of air while making it more humid which in turn only cools the air by a few degrees from the ambient temperature. This type of system would better be used in places where the moisture content is less with dry heat as places with high humidity won’t allow this system to be as effective. With an air conditioner, there is more control in variability as it can produce both heating and cooling functions higher or below ambient temperature. An AC has the added benefit of controlling humidity for comfort as well as conditioning the air which makes it good for any climate be it if it’s naturally dry or humid.

How often should I put coolant in my car?

Typically it’s recommended to change your coolant in your car every 30,000 miles, yet your car’s owner’s manual will give you more relevant specifications based on the make and model of your car.  Due to upgrades in car technology and parts, some have improved systems that won’t need a coolant change until after the first 60,000 miles while others can even wait as high as 120,000 miles! As of such, many service shops may recommend that you should do it more often than the maintenance schedule recommends such as every 30,000 or 50,000.

What happens if you dont change coolant?

It’s important to note that your coolant will actually deteriorate over time and no longer help in preventing rust buildup as it’ll by then become acidic. You can simply test to see if it’s still good with test strips that measure acidity. As of such, corrosion with rust can be damaging to the radiator, thermostat, water pump and other parts of the cooling system so it’s important to have your coolant tested at about 50,000 miles. A car inspection will allow you to catch onto the signs of rust, acidity and cooling and boiling points (with a hydrometer) before potential issues develop and impact your system to where you’d need cooling system repair.

How much does it cost to fix a cooling system?

Cooling system repair prices will range depending on the heating and cooling system that you have, the make and model of your car and the extent of damages from neglect. As of such, cooling system repair cost typically cost around $100 if no other parts of your car were affected by neglect and overheating.

What are the signs of low coolant?

Be sure to keep up with the signs that your coolant is low in order to avoid cooling system repair. With higher than normal car temperatures you may start to see the needle indication or digital display start to reach a red zone which indicates low coolant levels. Your coolant is what will keep your radiator from overheating and causing problems with your car so it’s important to keep watch of the temperature gauze meter whenever you’re driving. You may even see a light pop up on your dashboard of wavy lines which point to the coolant levels and temperature of your vehicle.  In hotter weather, your car has more immediate potential to overheating as the surrounding air is hotter than normal so be aware during that season as well. When white smoke comes out of the hood of your car this means that your antifreeze has mixed into the fuel supply or that your engine is now overheating from an issue with the coolant system.  Any trouble with the coolant can affect the heater as well since coolant passes through its core through valves. So if there’s a block with the coolant say with leaves or a leak then this can lead to the heater not responding as well.  A coolant leak can occur inside or outside of the engine and can be seen by leaving a trace on the road that is either pink, orange or green. Since the leaked fluid is toxic be sure to clean it from your floors if near your home so kids and pets are safe. As of such, when you’re in your car or around it you may be able to smell something sweet when a leak occurs. Finally, your engine light is a good indication as any that there are abnormalities with your engine and other parts of your car’s system that makes it operable.

Signs You Need Cooling System Repair

  • Low Coolant Levels
  • Visible Coolant Leak
  • Sweet Smell Indicating Leak
  • White Exhaust Smoke
  • Overheating
  • Rising Temperature Gauge
  • Engine Light

Can you drive a car without coolant?

Your car can still be operable without coolant for a while up to the point where the radiator and engine overheat and fail. Damages won’t be immediate in some cases yet your engine will be working in overtime which will lead to premature wear. Therefore in order to not risk damaging other parts and risking high replacement costs try to stay on top of low coolant level indications and signs. Coolant car service is relatively low and can even be grouped with an oil change if desired. Avoid the headache of auto repair and keep up with your vehicle’s maintenance periodically!

Why is the AC in My Car Not Working?

Tuning the AC Temperature in a Car

Keeping Your Cool in the Heat

Air conditioning plays a vital role in our day to day comfort. With cool, refreshing air available at the turn of a knob, it’s no wonder we so often take this comfort for granted. That’s especially true in our vehicles, where functioning AC plays an even more essential role in our safety.

What happens when that air conditioning breaks down, and how can we (as drivers) figure out what the problem likely is? We’ll be diving into the topic of car air conditioning service and repair today. By the end, you should have a basic idea of how to match symptom to related part failure, and you’ll definitely know when to schedule car AC repair! Let’s get started.

What to Do if AC is Not Cooling

“Why did my car AC stop blowing cold air?!” That’s a question our mechanics here all the time at Express Auto Repair & Emissions. Like certain engine power problems, AC malfunctions can be traced to a variety of potential part failures. That means that answering our question actually requires a little bit of digging.

Below, are a few familiar situations that will help us outline possible explanations. Of course, you could just bring your car straight to the auto maintenance shop, but where’s the fun in that?

Hot Air

What Does it Mean When Your Car AC Blows Hot Air?

Did you know that the air conditioning system operating in your vehicle is actually fairly similar to the one cooling your home? This system relies on a variety of moving parts, but it can only function with sufficient refrigerant. Modern vehicles rely on R-134a, a more environmentally friendly replacement for Freon. Think of it as the blood that allows your AC to thrive, only this cold fluid frequently alternates between liquid and gas states.

One of the common reasons why vehicles lose cooling capabilities is a shortage of refrigerant (many still call it “Freon”). Because the fluid won’t simply run out by itself, there’s usually a leaky part behind the problem. Most mechanics will point towards the compressor as the likely suspect, especially if the hot air is accompanied by loud clanging or squealing sounds.

Another potential cause could be the evaporator, where the refrigerant should cool the air blown by your fan. Just before the evaporator is the expansion valve, which moderates the intake of refrigerant. A faulty valve may check the fluid supply so that too little reaches the evaporator.

No Air

Why Did My Car AC Stop Blowing Air?

An even more serious problem is a complete lack of air coming out of the vents. This could indicate a multiple part failures or a single malfunction that triggered a shutdown. Again, with so many possible explanations, it often takes a professional to discern the true cause of the air conditioner failure.

Below, we’ll highlight our most common reasons for the AC to stop working.

  • Warm Air #1: Faulty Compressor
  • Warm Air #2: Choking Expansion Valve
  • Warm Air #3: Leak Refrigerant Hose or Seal
  • No Air #1: Burnt Out or Broken Blower Motor
  • No Air #2: Faulty Control Module
  • No Air #3: Degraded Relays or Resistors
  • No Air #4: A Failing Accumulator or Receiver-Dryer

Car AC Repair and Service

As you can imagine, different parts come with varying prices and labor requirements. While you could attempt to replace a few minor parts yourself, many parts of the air conditioning system should only be handled by a professional (especially refrigerant and electrical parts). After all, you wouldn’t want to add a hospital visit to your car AC repair cost!

Car AC Repair Cost Estimate

Let’s get to the big question: How much does it cost to get air conditioning fixed in a car? If you are having a noticeable drop in cooling capabilities, you’ll likely need to arrange a checkup and refrigerant recharge. That typically begins in the $100 to $300 range, though a related part replacement (likely in the event of leak) could push your costs into the upper hundreds.

Say your mechanic diagnoses a complete compressor failure under the hood. A part replacement of this size will launch your total into the thousands. At this point, only the most devoted car owners consider car AC repair. Most tend to start shopping for a replacement vehicle.

Why Change Fluids in Your Car?

Car fluids get topped off

We’ve got you covered whether your car fluids need a top off or a complete flush.

There are many features in a vehicle that some car owners take for granted. Your ability to turn smoothly without much force on the wheel. The way your brakes react so quickly when you slam your foot down on the pedal in an emergency. The smooth way your car shifts gears and allows you to continue to accelerate without abrupt stops or interference. All of these features are brought to homeowners through specialty pieces of equipment in your car. But just like your engine needs oil to stay lubricated and function properly, these pieces of equipment require their individual car fluids to ensure they operate at peak performance. But what does that mean for you as a vehicle owner? Which engine parts need car fluids, and which operate on something else entirely? You may not even know if you need to change these different car fluids, or just top them off.

What are My Different Car Fluids?

This can be a confusing thought for people not mechanically inclined. Most vehicle owners know to have their oil changed every 3,000 to 5,000 miles of use. Obviously this varies depending on the make and model of your car. You may have found yourself wondering “What fluids are in my car?” or “What color are the fluids in my car?” If you ever get a fluid leak in Schaumburg, IL, you’ll want to be able to figure out what you’re looking at. Knowing what color every liquid that can leak from your vehicle can help you diagnose the source of a leak quickly, potentially helping you minimize the damage to engine. Knowing the differences of car oil vs transmission fluid can save you money on diagnostics at the mechanic.

  • Light to Dark Brown This is engine oil. In terms of car fluids, this is the life-blood of your engine. It lubricates all of the moving pieces of your engine, and keeps it from degrading quickly. If your vehicle runs out of oil, or leaks too much of it, your engine can break down faster, and you can cause irreparable damage to one of the most expensive components in your car. The color of your oil changes based on time. The closer it is to your last oil change, the lighter the color of brown. The darker it gets, the closer you are to needing an oil change. If it contains sludge, it is supposed to. Most modern oils are made to keep contaminants in the oil itself, not dispersed through the engine. However, it can only do this for so long. That’s why you should pay attention to your driving patterns and owners manual to know when to get an oil change.
  • Pink, Red, or Brown If you have a leak, and the fluid is one of these colors with a thick and oily consistency, then you most likely have a transmission fluid leak. The output shaft seal and axle seal are the common culprits in a transmission fluid leak. Transmission fluid is to your transmission what engine oil is to your engine. It lubricates the moving parts in your transmission to prevent damage and degradation of a very expensive part of your vehicle. It also serves as to cool the transmission during extensive periods of use. If you have an automatic transmission, it also helps transfer power from the engine to the transmission.
  • Dark Red or Reddish Brown This is most likely power steering fluid. It has a thinner consistency than engine oil or transmission fluid. Essentially a pump pressurizes this fluid to help create hydraulic power to assist you in turning your vehicle. Without this, making hard turns would take much more force on the wheel. If you see this fluid, chances are you have a leak in the rack end seals for the rack and pinion power steering mechanism.
  • Pale Amber If it’s in your car and looks like cooking oil, chances are it’s brake fluid. The type of brake fluid in your car varies depending on the braking system. Anti-lock brake systems use glycol-based fluids, while non-ABS systems use silicone based fluids. Brake fluid essentially creates hydraulic pressure in your brake system. It assists your brake rotors to clamp down harder, helping you to brake faster and more effectively. If this leaks it could be a few things, including the brake caliper seals or your flex lines.
  • Bright Yellow or Green If you need to determine what that neon fluid is in your vehicle, it’s probably coolant or antifreeze. These could come from a number of places, including your car’s head gasket, freeze plugs, radiator, and others. These keep your car engine from overheating or freezing up. Moving components always run the risk of succumbing to the elements, and the addition of the proper amount of coolant and antifreeze to your car fluids can be the difference between a safe commute to work or a trip to the mechanic.

Maintenance for Car Fluids

Car fluids keep your vehicle in peak working condition

Give us a call if you’re curious about the condition of your car or car fluids.

Now that you can better determine which car fluids do what, you have to know proper maintenance. Just like oil, your vehicle will eventually need each individual system topped off, flushed, or completely drained and refilled with new fluid.

How do you know if your car is leaking fluid? If you ever look down and notice a pool of fluids underneath your vehicle, there is a good chance you have a leak. This is the most obvious way to determine a leak. Since the engine and other parts aren’t sealed, fluids leaking out of your engine will inevitably end up on the ground where you park. Pay attention to the color and consistency of the car fluids to determine the type of fluid leak, which will help determine the potential point of origin. If you find your car leaking fluid and overheating, there is a good chance you have a fluid leak and should seek repairs immediately to avoid permanent engine damage.

When should you change car fluids? Letting your car fluids go without inspection for too long could require you to need a Sugar Hill, GA auto repair center. This varies depending on the vehicle, the usage, and the system. Transmission fluid requires a complete flush and replacement somewhere between 30,000 miles and 100,000 miles. Some vehicles state you will never need to service this fluid. At the same time, your power steering fluid should be topped off when it seems to be running low. A good indicator is the ease of your turns while driving. If turning becomes more difficult, you could need more power steering fluid.

Mechanic changes car fluids

Our mechanics can get your car back on the road in a quick and efficient manner

What fluids should be flushed in a car? You can feasibly do this to all of your car fluids. Whether or not they require this is a completely different story. While old engine oil is drained away and replaced, a flush of the system can help remove gunk in the system itself. There is no method for car fluid cleaning, but a flush is a way to remove building up in car fluid systems of your vehicle. But how much does it cost to get all your fluids changed? Each of your car fluids will cost a different amount. A system flush will run from 80 dollars to 250 dollars. Throw in the cost of the replacement fluid and it can be more expensive. That’s why you should always do your research before committing to a complete system flush.

Car fluid bubbles could be indicative of an air leak in one of your car fluid systems, which can cause problems further down the road, and be potentially hazardous on the road. Any car fluid leaks could become serious problems further down the line. If one of your systems is leaking fluid on to other parts of your engine, you run the risk of a malfunction, and further problems. Now that you can better determine what your car fluids look like and what they do for your vehicle you’re better prepared in the event of a leak. If you’re in Schaumburg, IL and have a question about car fluids or need a car fluid leak repaired, contact Express Auto Repair & Emissions at 847-895-9131, and we’ll help get your vehicle back in peak operating condition.
