MAINTENANCE AND ADJUSTMENT 107 Coolant Coolant absorbs excessive heat from the engine and transfers it to the air at the radiator. If the coolant level becomes low, the engine overheats and may suffer severe damage. Check the coolant level each day before riding the motorcycle, also carry out the maintenance and adjustments in accordance with the periodic maintenance chart. Replenish coolant if the level is low. Change the coolant in accordance with the Periodic Maintenance Chart. Information for Coolant To protect the cooling system (consisting of the aluminum engine and radiator) from rust and corrosion, the use of corrosion and rust inhibitor chemicals in the coolant is essential. If coolant containing corrosion and rust inhibitor chemicals are not used, over a period of time, the cooling system accumulates rust and scale in the water jacket and radiator. This will clog up the coolant passages, and considerably reduce the efficiency of the cooling system. WARNING Coolant containing corrosion inhibitors for aluminum engines and radiators include harmful chemicals for human body. Drinking coolant can result in serious injury or death. Use coolant in accordance with the instructions of the manufacturer. Soft or distilled water must be used with the antifreeze (see below for antifreeze) in the cooling system.
