THE FORD COOLING SYSTEM
Cooling the Engine
19
The Ford engine is cooled by a circulation of water through
the water jackets which surround the cylinders, combustion
chamber and valve seats. The water is circulated by thermo -
syphon ac ion, the flow of water being accelerated by means of
a
centrifugal water pump located in the front of the cylinder bead.
This pump draws the heated water from the engine into the
upper radiator tank where it is cooled by filtering through
the
radiator tubes to the lower tank. The radiator is cooled by
means of the fan located just back of the radiator where it
draws
a current of air around the radiator tubes.
To prevent overheating ke p
the radiator well filled. The
capacity
of he cooling system is three gallons.
Adjusting the Fan Belt
The fan and water pump both operate from the same shaft.
The shaf
is driven by a "V" shaped rubber belt. The belt is
adjusted to thepropertension
when the car leaves the fac -
tory and
this adjustment
should not be changed unless
the belt slips. The adjustment
is easily made by loosening
the generator support to
engine screw and moving the
generator toward you. Do not
tighten the belt more than is
actually necessary to keep
it
from slipping.
Water Pump Packing Nut
Packing is used in forming F uro 9
a water tight connection Tightening Water Pump Shaft
around the water pump shaft. Packing Nut
Should a leak develop, lubri-
cate water pump shaft through water pump lubricator fitting,
then tighten the packing nut. A screw driver is used for this
purpose as shown in Fig. 9. Do not tighten the nut more than
is necessary to stop the leak.
Cleaning t.he Radiator
The entire circulating system should occasionally be flushed
out. To do this open the petcock at the bottom of the radiator
