Anti-Freeze
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
solutions of Ethylene Glycol marketed under various trade names.
Solutions containing calcium salts or other ingredients which pro-
mote 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 solu-
tions required for protection against freezing at various temperatures:
