GENERAL DESCRIPTION
The cooling system on all 1954 Cadillac engines
is a low capacity type, made possible by the small
cylinder head area exposed to flame and by high
mechanical
and combustion efficiencies,
which
decrease the amount of heat transferred to the
coolant. This allows a large amount of heat energy
to be converted into useful power to increase
engine efficiency.
The radiator cores are of the tube and center
construction. Water passages are wideandstraight
with smooth interiors to permit maximum coolant
flow and also effective cleaning of the radiator.
Pressure in the cooling system is controlled by
a pressure operated vent type radiator cap which
prevents the coolant from reachfng the overflow
pipe.As a pressureof 12 to 15 pounds is required
to open this valve, the boiling point of the solution
is raised and there is less likelihood of loss of
coolant, particularly volatile anti-freezes.
The water pump is centrally mounted at the
front of the cylinder block to assure even distri
bution of the coolant to both banks. The pump is
driven by a belt, which also drives the generator.
The coolant
is drawn from the bottom of the
radiator and delivered to both cylinder blocks
simultaneously. The coolant circulates around the
cylinders and up through drilled holes to thecylin
der heads. After circulating through the heads, the
coolant flows through the thermostat housing which
is located at the top of the water pump. Fig. 13-1.
A thermostat is used on all 1954 series cars to
control water temperature by restricting the flow of
coolant from the cylinder heads to the radiator when
the engine is cold.
When the thermostat is closed, the coolant from
the cylinder heads is drawn through a by-pass in
the pump body and recirculated through the cylinder
blocks. When the engine is sufficiently warm, the
thermostat will open and coolant will flow hack to
the upper radiator tank where it is cooled as it is
drawn through the radiator core, to the bottom, to
repeat the cycle. Air is drawn through the radiator
core by a four blade fan on 1954 -62 and
603
series
cars and a five blade fan on 75 and 86 commercial
cars.
