Specifications

The cooling system on your Cadillac has been designed to maintain
the predetermined right temperature for efficient engine operation,
and to protect your engine from the adverse effects of overheating.
The capacity of the system is 25 quarts.
The cooling system requires regular attention. The proper coolant
level is one inch below the bottom of the filler neck. Keep the system
leak-proof by having all connections tightened regularly. Have your
Cadillac Authorized Service Station clean and flush the system at
least twice a year, or every 6,000 miles.
® Cadillac Cooling System Inhibitor
Your Cadillac, when delivered to you, contained a charge of Cadillac
Cooling System Inhibitor, a special chemical that retards the forma-
tion of rust and scale. A fresh charge of Inhibitor should be added
whenever the system is drained and refilled, regardless of summer
or winter or whether an anti-freeze containing Inhibitor has been
used. Cadillac Cooling System Inhibitor is recommended because of
its effective action, and also because it can be safely used with
any standard anti-freeze.

Cadillac recommends the following available commer-
cial materials, which may be used for preparing anti-
freeze solutions to be used in automobile radiators:
denatured alcohol, methanol, propanol, ethylene glycol,
and distilled glycerines.
Kerosene or other oils, or solutions containing calcium
chloride, magnesium chloride, sodium silicate, or other
inorganic salts, honey, glucose or sugar, are not satis-
factory for use in the cooling system.

* Before Installing Antl-Freeze
The cooling system should be thoroughly cleaned, in-
spected, and serviced for winter operation. This insures
removal of all iron rust and scale. It is advisable to
install new hose for the radiator and heater when
ethylene glycol and glycerine solutions are used. Hose
previously swollen by water absorption has a tendency
to shrink when these materials are used, thus causing leaks. Regular
inspection of the entire system, to prevent leaks, should be made
frequently after the anti-freeze is installed, and special checks made
on hose connections, cylinder head, and water pump.
The Automatic Heating System (installed as an accessory when
ordered) is so located that it does not drain, even when the hose is
disconnected, unless air pressure is applied. Do not rely on draining
to prevent freezing on cars using this Heating System; be sure to
get some anti-freeze into the heater cores.
