The eighth character in the Vehicle Identification Number (VIN) identifies the engine. Adhesive-backed labels attached to the engine, laser etching or stampings on the engine block indicate the engine unit number/date code. All engines are stamped with a VIN derivative. For more information on the VIN derivative, refer to VIN Derivative .

The primary (1) and optional (2) location of the VIN derivative for the 3.0L (L46) engine and the 2.5L (LB8) engine is on the lower left front transaxle mounting surface.
