How to Tell If a Car Engine Has Been Replaced

If you’re thinking about buying a used car, it’s important to do your research and make sure that the vehicle is in good condition. One of the most important things to check is whether or not the engine has been replaced.

There are a few different reasons why an engine might need to be replaced. Some of the most common reasons include:

• The engine has suffered major damage due to an accident or other incident.
• The engine has worn out due to age or high mileage.
• The engine has been modified or rebuilt to improve performance.

If you’re not sure whether or not the car you’re considering has had its engine replaced, there are a few things you can look for.

Signs That an Engine Has Been Replaced

1. The engine looks newer than the rest of the car.

If you pop the hood and the engine looks brand-new while everything else looks older, that’s a sign that the engine may have been replaced. Of course, it’s also possible that the previous owner simply had the engine detailed, so this isn’t a surefire sign of an engine replacement.

2. The engine has a different VIN number than the rest of the car.

Every car has a unique Vehicle Identification Number (VIN), which is located on a metal plate under the hood. If the VIN on the engine doesn’t match the VIN on the rest of the car, it’s a sign that the engine has been replaced.

3. The engine has a different displacement or horsepower than the original engine.

If you know what the original engine specifications are for the car you’re considering, you can compare them to the current engine specifications. If the displacement or horsepower is different, it’s a sign that the engine has been replaced.

4. The engine has different accessories than the original engine.

The accessories on an engine, such as the alternator, power steering pump, and air conditioning compressor, are typically specific to that engine. If the accessories on the engine you’re considering don’t match the accessories on the original engine, it’s a sign that the engine has been replaced.

5. The engine has a different sound than the original engine.

Every engine has its own unique sound. If the engine in the car you’re considering sounds different from the original engine, it’s a sign that the engine may have been replaced.

What to Do If You Think the Engine Has Been Replaced

Once you’ve confirmed that the engine has been replaced, you’ll need to decide whether or not you still want to buy the car.
