2.4 Cooling Circuits
12M33 series gas engine is equipped with 2 cooling circuits.
a) High temperature cooling circuit to cool:

Cylinder block and cylinder head

Turbocharger

Engine oil through oil cooler
The internal circuit is designed for self-degassing.
To provide effective engine protection against freezing, chemical and galvanic corrosion,
cavitation and depositing, it is IMPERATIVE to use the recommended coolant as defined
in the 6.1 Coolant Recommendation . The high temperature coolant pump is located at
the engine’s front side (See item 2 of the above picture).
b) Low temperature cooling circuit:
The low temperature cooling circuit cools the charged air and gas.
