STORING THE CAR-If the car is to
be
stored during cold weather, both the radiator
and engine block must be drained. The drain
valve .for the radiator is located in the lower
right hand corner of the
radia
tor. It is easily
reached by opening hood. A drain valve for the
engine block is located on both sides of the engine
block.
The underseat heater should be drained
by disconnecting both hoses at the heater
.
.
NOTE: The drain valves on ,the engine block have no stop
on,
the valve. Open
with care. Open only enough to permit coolant to flow.
ANTI-FREEZE
When pouring alcohol or volatile type anti-freeze solution in the
radiator, be careful not to get any on the painted finish of your car.
If some should
be
accidentally spilled on a painted surface, rinse it
off at once with cold water to prevent any
damage.
Using the radiator capacities given on page 25 follow the anti-freeze
manufacturers recommendations given on the container as
,
to the
quantity of anti-freeze needed to adequately protect your car to the
expected low
temperature.
NOTE: Kerosene, calcium chloride,
sodium·
silicate, honey, sugar and like
materials are not satisfactory to use In the cooling ..
yst~.
Anti-freeze mixtures.<,re expensive so it is important not to lose
them'
through loose water connections. Before putting them in your radiator
it is a good idea to have the cylinder head gaskets and hose connections
inspected and carefully tightened, or,
if necessary, replaced.
BRAKES
WHEN TO ADJUST BRAKES-Engineers agree that the brakes
on your car need adjustment when the pedal goes within two inches
of the floorboard in making an ordinary stop with standard brakes.
With power brakes adjustment is needed when the pedal goes within
one inch of the floorboard. The reserve on both is needed to allow
for expansion of brake drums when making a fast
stop.
