Cooling system
400335-10
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)
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
Scalding hazard
During motorcycle operation, the coolant gets very hot and is under pressure.
–
Do not open the radiator, the radiator hoses or other components of the cooling system when the engine is hot. Allow the
engine and radiator to cool down. If you are scalded, hold the affected part under cold water immediately.
Warning
Danger of poisoning
Coolants are poisonous and a health hazard.
–
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
immediately. Change clothes that have come into contact with coolants. Keep coolants out of the reach of children.
