Engine number ("engine code" and "serial number") is located at front on cylinder block at top -arrow-.
Engine codes beginning with "C" are four-digit.
The first three digits of the engine code stand for displacement and the mechanical structure of the engine. They are stamped in the cylinder block, including the serial number.
The 4th digit describes the engine output and torque and depends on the engine control module.

NOTE:

The four digit engine code is on the type plate, vehicle data label and Engine Control Module (ECM).
