The engine number ("engine code" and "serial number") is located on the front of the cylinder block at the top -arrow-.
Engine codes beginning with "C" are four letters long.
The first three positions of the engine code stand for displacement and the mechanical engine structure. They are stamped in the cylinder block, including the serial number.
The fourth position represents the engine output and torque and is dependent on the engine control module.
Refer to the Maintenance Tables for the allocations of the engine codes.

The four digit engine code is on the type plate (market-specific), vehicle data label and engine control module.
