34 COOLING SYSTEM Cooling System The water cooling system is a pressurized forced circulation type When the engine load varies this system controls the engine temperature within narrow limits where the engine operates most efficiently In this way the engine performs stably in various riding conditions and is very durable When the engine is cold the thermostat is closed so that the coolant flow is restricted through the small hole causing the engine to warm up more quickly 1 Water pump Water jacket Water pipe Cylinder Cylinder head Water pipe Cylinder head Water temperature sensor 7 Thermostat 8 Radiator cap 9 Thermostatic fan switch 10 Cooling fan 11 Radiator 2 3 4 5 Coolant Level Inspection Coolant Coolant Deterioration Visually inspect the coolant in the reservoir tank off whitish cotton like wafts are observed aluminum parts in the cooling system are corroded If the coolant is brown iron or steel parts arc rusting In either case flush the cooling system olf the coolant gives off an abnormal smell when changing check for a cooling system leak It may be caused by exhaust gas leaking into the cooling system NOTE Be sure to inspect the coolant at the reservoir tank if the coolant is checked by removing the radiator cap the air must be bleed from the cooling system Situate the motorcycle so that it is perpendicular to the ground on its center stand Remove the seats left knecgrip Pad and left side cover Check the level through the coolant level gauge on the reservoir tank The coolant level should be between the FULL and the LOW marks NOTE Check the level when the engine is cold room or ambient temperature ODo not check the level by removing the cap If the cap is removed air may get into the coolant and lower cooling efficiency
