1954 Cadillac - GM Heritage Center

RADIATOR FILLER CAP
The radiator filler cap is located under the hood. The coolant level
should be checked at least every 2,000 miles, with the engine cold.
Care should be taken not to lose coolant when chocking.
A SAFETY PRECAUTION
Avoid removing the filler cap while the
engine is hot, as coolant may spray out.
However, should it become absolutely
necessary to do so, rotate the cap toward
the left until the first stop is reached and
allow pressure to escape. Then turn again
to the left to remove. Be sure the cap is
turned tightly when re-installed.
ENGINE EFFICIENCY AND PROTECTION
DEPEND ON PROPER COOLING
The cooling system of your Cadillac engine has been designed to
maintain pre-determined temperatures for efficient operation. On
Series 60 and 62 models equipped with heaters, the normal
capacity of the system is approximately twenty-two quarts.
The Series 75 capacity is 24½ quarts.
The cooling system requires regular attention. The proper coolant
level is two inches below the top of the filler neck when the
engine is cold. Keep the system leak-proof by having all connections
tightened regularly. Have your Authorized Cadillac Dealer
clean and flush the system twice a year for the best efficiency.

CADILLAC COOLING
SYSTEM INHIBITOR
Your Cadillac, when delivered to you,
contains a charge of Cadillac Cooling
System Inhibitor, a special chemical that
retards the formation of rust and scale
and reduces the possibility of water pump
squeal. Regardless of the season, a fresh
charge of Inhibitor should be added whenever
the system is drained and refilled,
even when an antifreeze containing
Inhibitor is being used. Cadillac Cooling
System Inhibitor is recommended because
of its effective action, and because it can
be safely used with any standard antifreeze.
Your Cadillac Dealer has it.
BEFORE THE MERCURY DROPS TO
FREEZING . . . HAVE YOUR CAR
PROTECTED WITH ANTIFREEZE
Cadillac factory engineers recommend using either a permanent
glycol-type or an alcohol base antifreeze, such as denatured
alcohol, methanol or propanol.
Kerosene, other oils or solutions containing calcium chloride,
magnesium chloride, sodium silicate or other inorganic salts are
not satisfactory for use in your Cadillac 1 car cooling system.
INSTALLING ANT1FREE7E
The cooling system should be thoroughly
cleaned, inspected and serviced
for winter operation before installing
antifreeze. Regular inspection of the
entire system to prevent leaks should
be made frequently after the antifreeze
is installed —especially the hose connections,
cylinder heads and water pump.
Cadillac Heating Systems are so
located that they do not drain, even
when the hoses are disconnected, unless
air pressure is applied. Do not rely on
draining to prevent freezing in cars
using Heating Systems; be sure to get
antifreeze into the heater cores to prevent
winter damage to the system.
Because your car is equipped with
windshield washers, the addition of a
proper mixture of Cadillac Windshield
Washer Solvent is advised at this time.
