Engine: Application and ID
Engine Number
The engine number ("engine code" and "serial number") are located at the front of the engine/transmission joint.
A label with the "engine code" and "serial number" is also affixed to the toothed belt guard.
The engine code is also included on the vehicle data label.
Vehicles with a Four Digit Engine Code:
Four digit engine codes beginning with "C" are used. The first three digits describe the mechanical structure of the engine 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 (ECM). The four digit engine code is on the type plate, the vehicle data label and the ECM.
