The owner must properly handle the coolant to prevent it from freezing, engine overheating and corrosion. Use only a high quality ethylene glycol antifreeze that contains corrosion inhibitors and is recommended for use in engines with aluminum cylinder blocks. (CM. LABEL ON THE ANTIFREEZE CONTAINER).
To prepare an antifreeze solution, use only distilled water or drinking water with a low mineral content. Water containing high levels of minerals or salts can damage the aluminum engine block.
The use of coolant with silicate corrosion inhibitors may cause premature wear of the cooling system pump or clogging of the radiator channels. Using tap water in the cooling system may cause engine failure.
The cooling system of this model motorcycle is filled at the factory with a 50% solution of antifreeze and distilled water. This coolant composition is recommended for most temperature conditions and provides good corrosion protection. Higher antifreeze content will reduce the efficiency of the cooling system and should only be used in extremely cold environments. If the antifreeze concentration is less than 40%, it is impossible to provide sufficient protection of the cooling system from corrosion. At temperatures below zero, you should regularly check the cooling system and, if necessary, increase the antifreeze concentration (maximum up to 60%).
The coolant expansion tank is located on the left side under the fuel tank. Check the coolant level in the expansion tank (1), when the engine is warm and the motorcycle is in an upright position. If the coolant level is below the LOWER mark (3), unscrew the screws (4) remove the expansion tank cap (5) and remove the expansion tank cap (6). Add coolant to the UPPER mark (2). Always add coolant to the expansion tank only. Do not attempt to add coolant by opening the radiator cap.
If the expansion tank is empty or there is significant loss of coolant, check for coolant leaks and have it repaired by an authorized Honda dealer.
