A vehicle identification number (VIN) is composed of a unique combination of 17 letters and numbers that identify a specific vehicle. Each of the the letters and numbers stands for something such as the country and year of manufacture; make and model; manufacturing plant name and location and equipment specifications, such as engine size. To find out the engine size of a specific vehicle, you will need to decode the VIN.

Step 1

Navigate to and enter the vehicle's VIN into the designated box.

Step 2

Click "Go" to submit the information to the VIN decoder.

Locate the engine size next to the "Cylinders" heading on the VIN decoder screen.


  • Check your vehicle's dashboard, driver's door jamb, firewall or engine block for the VIN number, or look at the insurance or registration papers for the information. It also might be permanently etched in the glass of the car window.
  • The letters I, O and Q are not used in vehicle identification numbers to avoid confusion.
