The engine code can also be found on the vehicle data label and on the crankcase above the transmission.

The engine number consists of up to nine alphanumeric characters. The first part (maximum three letters) represents the "engine code", the second (six digit) is the "serial number". If more than 999, 999 engines with the same engine code are produced, the first of the six characters is replaced with a letter.

Vehicles with Four-Letter Engine Codes

Four-letter engine codes beginning with "C" are used. The first three letters describe the mechanical engine structure and are still stamped on the engine, as before. The fourth digit describes the engine output and torque and depends on the Engine Control Module -J623-. The four-digit engine code is on the type plate, the vehicle data label and the engine/motor control module.
