A sticker with the "engine code" and "serial number" is also on the intake manifold.
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.
