Engine coolant maintains normal operating
temperatures. Coolant flow is as follows:
Coolant is drawn from the radiator by the cool-
ant pump. It is pumped through the oil cooler,
and the engine block, up to the cylinder heads,
and into the thermostat housing. The coolant
then passes through a deaerator elbow and back
to the radiator. The deaerator elbow swirls the
coolant to remove air. This air is vented back to
the auxiliary tank.
The auxiliary tank provides for coolant overflow
from the radiator. The tank also vents air out
through its cap.
