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.
