Scheme 95: Engine Identification
The vehicle identification number (VIN) (1) is located on the left side rear of the engine block and is typically a 9 digit number stamped or laser-etched onto the engine at the vehicle assembly plant.
- The first digit identifies the division.
- The second digit identifies the model year.
- The third digit identifies the assembly plant.
- The fourth through ninth digits are the last 6 digits of the VIN.
