DESCRIPTION AND OPERATION
The system is of the full flow type with a centrifugal pump.
The thermostat, located in the cylinder head, controls the
flow through the system maintaining the proper
temperature.
The coolant flow is from the bottom of the radiator to the
pump which delivers it to the cylinder block. It then flows
through the cored passages to cool the entire length of
each cylinder wall. Upon reaching the rear of the cylinder
block, the coolant is directed upward into the cylinder head
where
seats.
it cools the combustion
chambers, valves and valve
The coolant from the cylinder head flows past the
thermostat, if it is open, through the coolant outlet housing
and into the top of the radiator.
Another passage in the head routes the warm coolant
through the intake manifold to help atomize the fuel
mixture, and then through a hose to the inlet hose of the
water pump.
