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 labelled 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 provide sufficient protection against corrosion and freezing. Concentrations of greater than 60% coolant will impair cooling efficiency and are not recommended. Lowmineral 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 reserve tank, the cooling system should be checked for leaks and repaired if necessary. Coolant must then be added to the radiator. RESERVE TANK

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 labelled 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
provide
sufficient
protection
against
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.
