15 COOLING SYSTEM 223
15.1 Cooling system
400415-10
The water pump with a 3D water pump wheel

in the engine ensures forced circulation
of the coolant. The heat exchanger enables faster warming of the engine oil at the start of a
journey and better heat dissipation for the engine oil during the journey.
The pressure in the cooling system resulting from heat is regulated by a valve in the radia-
tor cap

. The heat expansion causes the surplus coolant to flow into the compensating
tank

. When the temperature falls, this surplus coolant is sucked back into the cooling
system.
401167-10
Cooling takes place by means of the air stream and a radiator fan

, 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 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.
