4.6L Engine VIN Derivative and Identification Locations

The engine code letter is the eighth digit of the VIN, which identifies the engine.

Stick-on labels attached to the engine, laser etching, or stampings in the engine block indicate the engine unit number/build code date.

The engine ID number will be located on the front of RH rocker cover or the RH side of oil pan rail (1), and the VIN derivative is located on the engine block in front of the transaxle extension (2).
