Cooling System Description

The generator set engine is water cooled. The closed
loop cooling system includes the engine water pump,
which circulates the cooling water, and the engine
thermostat which opens and closes the cooling water
flow to maintain a constant engine temperature.
Depending upon the installation requirements, the fan
may be pusher type that blows air away from the engine
or a suction type that draws air toward the engine.
Hot water from the engine is cooled in a radiator and
then returned to the water pump for recirculation in the

cooling passages of the engine. Depending upon the
generator set model, the radiator may be mounted
in-line (on the front of the engine) or at a remote location
by the coach manufacturer. Components of the cooling
system with an in-line radiator are shown in Figure 3-11
and Figure 3-12. For a cooling system with a remote
radiator, the radiator and its mounting provisions on the
engine are replaced by a belt guard. See Figure 3-13.
Hoses then connect the water pump and thermostat
ports to the remote radiator. Either system may include
an optional overflow tank connected to the overflow tube
from the radiator.
