Scheme 14: Engine Identification

The Vehicle Identification Number - VIN derivative (1) for 3900 LZ9 is stamped or laser etched on the front and left side of the engine block. The Vehicle Identification Number - VIN derivative is nine digits long and can be used to determine if a vehicle contains the original engine.

  1. The first digit identifies the division.
  2. The second digit identifies the model year.
  3. The third digit identifies the assembly plant.
  4. The fourth through ninth digits are the last six digits of the Vehicle Identification Number - VIN.
