16 COOLING SYSTEM

16.1
Cooling system
B01782-10
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 radiator cap
. The specified coolant temperature is therefore permissible with-
out the danger of malfunctions.
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
cooling effect.
The radiator fan provides extra cooling. It is controlled by a thermoswitch.
16.2
Checking the antifreeze and coolant level
Warning
Danger of scalding
During motorcycle operation, the coolant gets very hot and is under pressure.
–
Do not remove the radiator cap, radiator hoses or other cooling system components when the engine is hot. Allow the
engine and cooling system to cool down. In case of scalding, rinse immediately with lukewarm water.
Warning
Danger of poisoning
Coolant is poisonous and a health hazard.
–
Coolant must not come into contact with the skin, eyes, or clothing. If contact occurs with the eyes, rinse with water
immediately and contact a physician. Immediately clean contaminated areas on the skin with soap and water. If fuel is
swallowed, contact a physician immediately. Change clothing that is contaminated with coolant. Keep coolant out of
reach of children.
Condition
The engine is cold.
