Your engine is the heart of your car, so fixing a blown-out or severely damaged one can be a grueling job for even the most seasoned mechanic. You might ask if it’s expensive to fix an engine. No matter how you look at it, typical engine replacement costs will always be high, ranging from $1,700 to $8,000. If you have a low budget, used engines cost $400 to $1,000, while rebuilt ones cost $2,500 to $4,000.

How much should you pay for a new engine? Basically, new engines cost almost as much as the market value of your car. It’s overwhelming, but you don’t have to dive into it unprepared. You can use the figures estimated in this price guide as a benchmark for your budget. Get a professional mechanic to properly diagnose your vehicle’s engine before committing to an engine replacement.

Signs that your engine is failing

Engines can enable cars to travel hundreds of thousands of miles, and they can last a lifetime. So what causes engine failure? Since everything in your vehicle is connected, engine failure can manifest differently. Here are a few things you can look out for:

  1. Check engine light - Almost all modern vehicles have this. The light will detect minor and major issues, so take your car to a nearby mechanic for a detailed diagnosis.

  2. Performance dip - This can mean slower speeds, groaning, or stalling. Once you feel your engine isn’t running smoothly, take it to a mechanic.

  3. Engine knocking - The knocking sound is caused when the air and fuel mixture creates micro explosions inside your engine’s cylinder or when there’s a failing engine bearing and other mechanical issues.

  4. Grinding noises - It’s bad if you hear your engine grinding every time you use it. This means there is a lack of lubrication, which results in metal-on-metal contact among moving parts. 

  5. Exhaust Increase - Much smoke from your vehicle signifies something that shouldn’t be burning in the engine.

What affects the average cost of engine replacement?

Vehicle make and model

Since most cars are made to house a specific engine type and size, the cost of engine replacement will depend a lot on your vehicle’s make and model. Stock engines for a daily driver or economy car are far cheaper than those for SUVs and sports cars. 

Engine condition

You must decide if you’ll get a new, used, or rebuilt engine since product quality will significantly affect your engine replacement cost. 

  • Brand-new is always better, but it’s expensive. 

  • Used engines are cheaper but risky. You’ll need to factor in engine age, mileage, and shipping costs. If it fails, you’ll end up spending more.

  • Rebuilt engines are pricier than used engines but not as expensive as brand-new ones. During a rebuild, your engine is disassembled and inspected. It is then cleaned, and any worn-out or damaged part is restored or replaced to extend the engine’s service life and bring it back up to standard. Proper rebuilding makes your engine seem good as new.

Labor fees

Labor prices depend on where you live and your mechanic’s skill and expertise. Also, since labor is charged by the hour, an engine swap will cost more the longer the job takes. Sadly, there are no standard fees for mechanics to follow. It’s best to find a skilled mechanic and request a quote. 

Additional expenses

What else should you consider when replacing an engine? You might also need the following services: 

  • Belt, pipe, and hose replacement 

  • Water and fuel pump repair or replacement

  • Engine mount replacement 

  • Vehicle electrical repair

If you plan on driving your car for years and it has sentimental value, replace its engine. But if you have the budget, you’re better off buying a new car instead.

It depends on your budget and your appetite for risk. If you have the money to spare and the new engine isn’t more expensive than the car itself, proceed with the transaction. However, an engine rebuild is the next best thing for those with smaller budgets.

Odometers record the miles run on car engines and other components. But thankfully, you don’t have to worry about odometer fraud because replacing your engine doesn’t reset the mileage count.

Most car insurance providers don’t cover engine repair and replacement unless the damage results from an accident. They could shoulder engine replacement costs but also choose to pay you out instead, especially if the component has a very high price.
