NOTE: Never race the engine until the oil gauge needle will
stay ·around the midpoint of the gauge.
7. The Chevrolet cooling system is designed to maintain
efficient engine-operating temperatures and to provide adequate
and uniform cooling even under the most severe operating
conditions.
A thermostat placed at the water outlet of the cylinder head
restricts and controls the water circulation as the engine warms
up. The thermostat is rated at 160 degrees.
Truck cooling systems incorporate a by-pass cooling feature
which enables the coolant to circulate in the engine even when
the thermostat stops the flow to the radiator. This helps to
keep the coolant temperature in the engine uniform.
HOT WEATHER OPERATION
Hot weather does not generally present as many problems
as cold weather; however, a little special attention will pay
dividends in the form of economy and convenience.
L Check the radiator regularly for sufficient coolant as the
rate of evaporation is higher in hot weather.
2. Make sure the fan belt is in good condition and properly
adjusted.
3. Keep the radiator area free of bugs and other things that
restrict air circulation.
4. Have the water level in the battery checked at 10-day
intervals or oftener, if necessary.
5. Starting a cool engine in hot weather does not present a
problem and the procedure outlined under "Starting the
Engine" should be followed.
A hot engine 'is easily flooded and may start hard. If the
carburetor is flooded proceed as follows on models equipped
with a manual choke:
a. Turn on ignition.
b. Pull hand throttle knob out about
%".
c. Do not pull choke knob out or step on accelerator.
d. Engage starter without depressing accelerator.
e. When engine starts, release starter, but do not accelerate
engine.
On models with automatic choke, see NOTE on page 18
for procedure to be followed in case of flooding .
