Scheme 8: Engine Identification

The primary Vehicle Identification Number-VIN derivative for the 3800-L36 and 3800-L67 is stamped or laser etched on the left side of the engine block above the starter motor (1).

Scheme 9

Scheme 9

The secondary Vehicle Identification Number-VIN, derivative for the 3800-L36 and 3800-L67 is stamped or laser etched below the water pump on the engine block (1). The Vehicle Identification Number-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 digit are the last six of the Vehicle Identification Number-VIN.
