Engine Number/Engine Characteristics

Engine Number

The engine code - arrow A - and engine number - arrow B - ("serial number") are located on the rear side of the engine, above the partition of the cylinder block/upper oil pan.






The engine code is also stamped on the right cylinder head and on the cylinder block.

A label with the "engine code" and "serial number" is also affixed to the toothed belt guard.

The first three digits describe the mechanical structure of the engine and are still stamped on the engine. The fourth position describes the engine output and torque. It depends on the Engine Control Module (ECM). Four digit engine codes are found on the type plate and vehicle data label. It can also be read via the ECM.
