Task #24 - Radiator Coolant
The ACE has a liquid cooled engine and therefore you must maintain a proper level of radiator coolant, just like in a car. Honda recommends that you use only Honda HP coolant or an equivalent high quality ethylene gylcol antifreeze containing corrosion protection inhibitors specifically recommended for use in aluminum engines.
NOTICE: Using coolant with silicate inhibitors may cause premature wear of water pump seals or blockage of radiator passages. Using tap water may cause engine damage. Use only low-mineral drinking water or distilled water as part of the anti-freeze solution.
Your ACE comes with a 50/50 solution of antifreeze and distilled water. A higher concentration of antifreeze decreases the performance of the cooling system and is only recommended when aditional protection from freezing is needed. A concentration of less then 40% antifreeze will not provide proper corrosion protection for your aluminum engine. So basically, you should just keep it a 50/50 mixture or buy a pre-mixed product that is equivalent to 50/50.
	The reserve tank is located behind the radiator(4). Check the coolant level in the reserve tank while the engine is at normal operating temperature. It should be between the UPPER(1) and the LOWER(2) level marks. When the coolant level is at the LOWER mark, then add new coolant up to the UPPER mark. Always add coolant to the reserve tank only. Do not attempt to open the radiator cap while the engine is hot. - Changing the Coolant
