Cooling System - Honda 1992 Accord Coupe Owner's Manual

Cooling System

The engine in your Honda contains a number of aluminum parts.
Therefore, it requires an antifreeze/coolant specifically formulated
to protect the aluminum parts from corrosion. Failure to use a
suitable antifreeze/coolant may seriously shorten the life of the
engine as the result of rapid corrosion damage. Some antifreeze/
coolants, although labeled for use in engines containing aluminum,
may not provide adequate protection for your engine.
Therefore, use only a Honda-recommended antifreeze/coolant.
CHECK WITH YOUR AUTHORIZED HONDA DEALER.
For best corrosion protection, the mixture of coolant and water
must be maintained year-round at 50/50. Concentrations less than
50% coolant may not
corrosion and freezing. Concentrations of greater than 60% coolant
will impair cooling efficiency and are not recommended. Low-
mineral drinking water or distilled water should be mixed with the
antifreeze/coolant. Coolant loss should be replenished by a mixture
containing the proper concentration of antifreeze and water.
Do not mix different antifreeze/coolants.
Do not use additional rust inhibitors or anti-rust products, as they
may not be compatible with the radiator coolant.
ENGINE DAMAGE CAUSED BY IMPROPER COOLANT USAGE IS
NOT COVERED BY THE NEW CAR WARRANTY.
Checking Coolant
Check the coolant level in the reserve tank when the engine is at
normal operating temperature.
If the level is below the MAX
mark, but still visible, add a 50/50
solution of antifreeze and water
to bring it up to MAX.
If there is no coolant in the re-
serve tank, the cooling system
should be checked for leaks and
repaired if necessary. Coolant
must then be added to the radi-
ator.
