Scheme 36: Engine Identification (LAF, LEA, or LUK)
Scheme 36: Engine Identification (LAF, LEA, or LUK)

Identification can be made through the use of the Broadcast Code label on the engine (1) and the use of the partial VIN etched in one of two places - the primary location is on the starter motor flange (2). The secondary location is the oil filter bowl.
