ENGINE COOLING CIRCUIT
DESCRIPTION
The generator's engine is fresh water cooled (engine coolant)
by an engine-mounted heat exchanger. Raw water is pumped
through the heat exchanger by a belt-driven, positive
displacement impeller pump. Mtcr the raw water cools the
fuel in the gasdenser and cools the engine coolant in the heat
exchanger, it mixes with the engine's exhaust gases, cools the
exhaust hose, and discharges overboard.
The engine's coolant is circulated by a belt-driven centrifu-
gal-type metal impeller pump mounted on the front of the
engine.

The engine's coolant temperature is thennostatically
controlled.
The engine's cooling system should be drained, flushed out,
and refilled with a fresh mixture of coolant at 750 operating
hours or every two years.
A
CAUTION:
Proper cooling system maintenance is
critical; almost half of engine failures can be traced
back to cooling system corrosion.
