Identification can be made through the use of the Broadcast Code label on the timing chain housing cover (1) and the use of the partial VIN etched on the left side of the engine block next to the starter (2).
The broadcast code identifies the engine, transmission, and vehicle relationship. The partial VIN identifies the specific vehicle by sequence number.
