MAINTENANCE WORK ON CHASSIS AND ENGINE 55
Cooling system
400242-10
The water pump in the engine forces the coolant to flow.
The pressure resulting from the warming of the cooling system is regulated by a valve
in the radiator cap
. The specified coolant temperature is therefore permissible with-
out danger of function problems.
120°C (248°F)
Coolant ( P. 82)
Cooling is effected by the air stream.
The lower the speed, the less the cooling effect. Dirty cooling fins also reduce the cool-
ing effect.
Checking antifreeze and coolant level
Warning
Danger of scaldingಗThe coolant gets very hot when the motorcycle is driven and is under high pressure.
ಥ Do not open the radiator, radiator hoses or other cooling system components when the engine is hot. Allow the engine and
cooling system to cool down. If you scald yourself, hold the affected area under cold water immediately.
Warning
Danger of poisoningಗCoolants are poisonous and a health hazard.
ಥ Avoid contact between coolants and skin, eyes and clothing. If fuel gets into your eyes, rinse immediately with water and
contact a doctor. Wash affected skin areas immediately with soap and water. If coolant is swallowed, contact a doctor im-
mediately. Change clothes that have come into contact with coolants. Keep coolants out of the reach of children.

ಥ Stand the motorcycle upright on a horizontal surface.
ಥ Remove the radiator cap.
ಥ Check antifreeze of coolant.
-25… -45°C (-13… -49°F)
» If the antifreeze of the cooling liquid does not meet specifications:
ಥ Correct antifreeze of coolant.
ಥ Check the coolant level in the radiator.
Coolant level
above radiator fins. 10mm (0.39in)
» If the level of the cooling liquid does not meet specifications:
ಥ Correct the coolant level.
Alternative 1
Coolant ( P. 82)
Alternative 2
Coolant (mixed ready to use) ( P. 82)
ಥ Refit the radiator cap.
