COOLING SYSTEM
The cooling system consists of an engine cooling
module, thermostat, coolant, and a water pump to
circulate the coolant. The engine cooling module may
consist of a radiator, electric fan and motor assembly,
shroud, radiator pressure cap, coolant recovery sys-
tem (CRS), hoses, and clamps.
• When Engine is cold: Thermostat is closed, cool-
ing system has no flow through the radiator. The
coolant bypass flows t h r o u g h the engine only.
• When Engine is w a r m : Thermostat is full open,
coolant flows through the radiator and flows through
the heater to water pump.
Its p r i m a r y purpose is to m a i n t a i n engine temper-
ature i n a range t h a t w i l l provide satisfactory engine
performance and emission levels under a l l expected
driving conditions. I t also provides hot water (cool-
ant) for heater operation. I t does this by transferring
heat from engine metal to coolant, moving this
heated coolant to the radiator and heater core, and
then transferring this heat to the ambient air.
The coolant flow circuit is shown i n (Fig. 1).
RADIATOR
The radiators are cross-flow types (horizontal
tubes) w i t h design features t h a t provide greater
strength as w e l l as sufficient heat transfer capabili-
ties to keep the engine satisfactorily cooled.
