COOLING SYSTEM
135
15.1
Cooling system
B00980-10
The water pump
1
in the engine forces the coolant to flow.
The pressure in the cooling system resulting from heat is regulated by a valve in the radi-
ator cap
2
. The heat expansion causes the surplus coolant to flow into the compensating
tank
3
. When the temperature falls, this surplus coolant is sucked back into the cooling
system. This permits the specified coolant temperature without causing any malfunctions.
125 °C (257 °F)
100167-10
Cooling takes place by means of the air stream and a radiator fan
4
, which is controlled by
a thermoswitch.
The lower the speed, the less the cooling effect. Dirty cooling fins also reduce the cooling
effect.
15.2
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.
