A.VI COOLING
GENERAL
Forced feed cooling system
with
vane-type cen-
trifugal pump and thermostat regulated (Fig.
A.VI/1).
The coolant flow
is
cooled through a verticle
tube type radiator core and a fan pulls
cooling
air
through the core.
The cylinder head water pipe houses the fixed·
setting thermostat which, when the coolant is
R V
cold,
blocks
the
flow
of
coolant
to
the radiator
until
the
coolant
warms up
to
correct operating
temperature, as follows:
1.
With
the thermostat closed, the coolant (cir-
culates
only
between pump and engine (by·
pass circuit),
excluding
the radiator.
2.
With
the
thermostat
open, the coolant flows
through the radiator also, thus excluding,
partially
or
In full, the by-pass
circuit.
The
cooling
system capacity is
14
Ots.
(13.3
lit
res).
