COOLING SYSTEM

14.1
Cooling system
400415-10
The water pump with a 3D water pump wheel

in the engine ensures forced circula-
tion 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
radiator cap

. The heat expansion causes the surplus coolant to flow into the com-
pensating 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 con-
trolled by a thermoswitch.
The lower the speed, the less the cooling effect. Dirty cooling fins also reduce the cool-
ing effect.
14.2
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.
Condition
The engine is cold.
The radiator is completely full.

–
Rest the motorcycle on its side stand on a horizontal surface.
–
Check the coolant level in the compensating tank.
The coolant level must be between MIN and MAX .
» If there is no coolant in the compensating tank:
–
Check the cooling system for leaks.
x
Info
Do not operate the motorcycle!
–
Add coolant/bleed the cooling system.
x
( p. 81)
» If the coolant level in the compensating tank does not meet specifications, but
the tank is not empty:
–
Check the cooling system for leaks. x
–
Fill the cooling system compensating tank. ( p. 80)
14.3
Filling cooling system compensating tank
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.
–
Avoid contact between coolant and skin, eyes and clothing. If it gets into your eyes, rinse immediately with water and con-
tact a doctor. Wash affected skin areas immediately with soap and water. If coolant is swallowed, contact a doctor immedi-
ately. Change clothes that have come into contact with coolants. Keep coolant out of the reach of children.
