Anti-Freeze - Hudson Terraplane Special 1935 Owner's Manual

OWNER'S MANUAL
After thoroughly flushing the cooling system, the addition of Terraplane Hudson Rust
and Corrosion Inhibitor to the water will neutralize the action of any compound which
may not have drained out. It will also prevent corrosion of the cast iron, aluminum and
other metals in the cooling system. The practice of using the Inhibitor in the cooling
system is particularly advantageous for engines equipped with aluminum cylinder heads.
Terraplane Hudson Radiator Cleaner and Inhibitor can be obtained from any Autho-
rized Terraplane and Hudson Dealer.
Before putting any anti-freeze in the cooling system, it should be thoroughly cleaned,
all hose connections and gaskets checked for leaks, and the water pump packing replaced
if necessary.
The types of anti-freeze recommended are: Alcohol, Glycerine and solu¬tions of
Ethylene Glycol marketed under various trade names.
Solutions containing calcium salts or other ingredients which promote electrolytic
action should be avoided. They will cause serious corrosion of aluminum alloy as well as
the solder joints of the radiator. Also avoid the use of solutions containing glucose or
honey, as they will tend to clog the system; and of kerosene or fuel oil which, when hot,
liberate inflammable vapors.
The following table gives the quantities of the recommended solutions required for
protection against freezing at various temperatures:
