General information
Caution
● While the engine is running, never attempt to open the radiator filler cap, the pressurized hot
coolant may shoot out and cause serious scalding injury. No maintenance work is allowed to
perform unless the engine is completely cooled down.
● Refill the radiator with distilled water or specified additives.
● Add coolant to the reservoir.
● The cooling system can be serviced on the motorcycle.
● Never spill the coolant to the painted surface.
● Test the cooling system for any leakage after the repair.
● Please refer to Ch3 for inspection of TW sensor.
