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 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
