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.

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

The entire circulating
system should occasionally be flushed
out. To do this open the petcock at the bottom of the radiator
