How to Know if Car Engine is Changed

There are a few reasons why you might need to know if a car engine has been changed. Maybe you’re buying a used car and want to make sure the engine is original, or maybe you’re having engine problems and want to rule out the possibility that the engine has been swapped with a different one.

Whatever the reason, there are a few ways to tell if a car engine has been changed.

1. Check the VIN

The VIN (Vehicle Identification Number) is a unique 17-digit code that is assigned to every car. It can be found on the car’s title, registration, and insurance card. The VIN contains information about the car’s make, model, year, and engine type. If the VIN on the car you’re inspecting does not match the VIN on the title or registration, it’s possible that the engine has been changed.

2. Check the engine block

The engine block is the main part of the engine. It contains the cylinders, pistons, and crankshaft. The engine block is usually stamped with the engine’s serial number. If the serial number on the engine block does not match the serial number on the title or registration, it’s possible that the engine has been changed.

3. Check the engine mounts

The engine mounts are the rubber or metal parts that attach the engine to the frame of the car. If the engine mounts are new or look different from the other mounts on the car, it’s possible that the engine has been changed.

4. Check the engine wiring

The engine wiring is the electrical system that connects the engine to the rest of the car. If the engine wiring is new or looks different from the other wiring on the car, it’s possible that the engine has been changed.

5. Check the engine computer

The engine computer is the brain of the engine. It controls the engine’s fuel injection, ignition, and timing. If the engine computer is new or looks different from the other computers on the car, it’s possible that the engine has been changed.

If you’re not sure if the engine in a car has been changed, it’s best to have it inspected by a mechanic. A mechanic will be able to tell you for sure if the engine has been changed and, if so, what type of engine it is.

Additional Tips

• If you’re buying a used car, ask the seller for the car’s maintenance records. These records can show you if the engine has been serviced or replaced.
• If you’re having engine problems, take the car to a mechanic for a diagnosis. The mechanic will be able to tell you if the engine problems are due to a problem with the engine itself or if they are due to another problem with the car.
• If you’re still not sure if the engine in a car has been changed, you can have the car inspected by a VIN verification service. These services can compare the VIN on the car to the VIN on the title and registration to tell you if the engine has been changed.
