How to Find Engine Size on Car

Introduction

The engine size of a car is an important factor to consider when purchasing or maintaining a vehicle. It affects the car’s performance, fuel efficiency, and emissions. If you’re not sure what engine size your car has, there are a few ways to find out.

1. Check the Vehicle Identification Number (VIN)

The VIN is a unique 17-digit code that identifies your car. It can be found on the driver’s side door jamb, under the hood, or on the vehicle registration card. The VIN contains a lot of information about your car, including the engine size. The engine size is typically located in the 5th or 6th character of the VIN.

For example, if the VIN is 1G1FB14Y25Y123456, the engine size is 5.0 liters. This is because the 5th character of the VIN is “5,” which corresponds to a 5.0-liter engine.

2. Check the Owner’s Manual

The owner’s manual for your car will contain a lot of information about the vehicle, including the engine size. Look for a section in the manual that discusses the engine specifications. The engine size will typically be listed in cubic centimeters (cc) or liters (L).

For example, if the owner’s manual says that the engine size is 3,000 cc, this means that the engine has a displacement of 3,000 cubic centimeters. This is equivalent to 3.0 liters.

3. Check the Engine Code

The engine code is a unique code that identifies the specific engine that is installed in your car. It is typically located on a metal plate on the engine block. The engine code can be used to look up the engine size in a reference book or online database.

For example, if the engine code is LFX, this corresponds to a 3.6-liter V6 engine. You can find this information by searching for the engine code online or in a reference book.

4. Measure the Engine Displacement

If you have access to the engine, you can measure the engine displacement yourself. This is done by removing the spark plugs and using a piston stop to measure the distance from the top of the piston to the top of the cylinder. The engine displacement is calculated by multiplying the bore (the diameter of the cylinder) by the stroke (the distance the piston travels up and down) by the number of cylinders.

For example, if the bore is 90 mm, the stroke is 84 mm, and there are 6 cylinders, the engine displacement would be 3,498 cc. This is equivalent to 3.5 liters.

Conclusion

Finding the engine size of your car is a relatively simple task. By following the steps outlined above, you can easily determine the size of your engine.
