15 COOLING SYSTEM 133
401768-10
The coolant is cooled by the air stream and a radiator fan 4, which is controlled by a ther-
moswitch.
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.
