Diagram of engine cooling system.
There are six major parts to the cooling system
-radiator, thermostat, pressure-type filler cap,
fan, water pump and hose connections. Capacity:
10 quarts (8 Imperial quarts).
RADIATOR CAP
Pressure-type permits 3 to 4
pounds internal pressure, raising boiling point of
coolant 12 to 16 degrees.
"Don't remove
pressure
cap
when
radiator's very hot."
Remove radiator cap
slowly and carefu/Jy
when
engine is hot to prevent inj
u
ry from escaping
steam or scalding water. Remove cap when drain-
ing radiator.
RADIATOR FAN
Four-blade, pull-type, mounted
23
on pump pulley. Tums on a
sealed, pre-lubricated
bearing which needs no additional lubrication.
Allow approximately Y2 inch slack in adjusting fan belt.
THERMOSTAT
Bellows-type, in upper radiator
hose. When engine is first started, the thermostat
remains closed until coolant temperature reaches
approximately 160 degrees. Then bellows expand,
opening valve to permit water circulation.
Note: Install thermostat with bellows nearest
engine.
