COOLING SYSTEM
The coolant
is
drawn from the
bottom of the radiator by
the
water
pump which delivers the coolant to
the cylinder block
(Fig.
8) .
As the coolant enters the block, it
travels through cored passages to
cool the entire length of each cylin-
der wall. Upon reaching the rear
of
·•
the cylinder block, the coolant is
A .
directed upward into the cylinder
head where it cools the combustion
chambers, valves, and valve seats on
, "'
its return to the front of the engine.

'
.
At this point, the coolant tl.ows
into the coolant outlet connection,
past the thermostat if it is open, and
irito the top of the radiator. If the
thermostat is closed, a small portion
of tbe coolant is returned to the
water pump for recirculation
.
The.
entire system
is
pressurized to 13-15
psi.
