COOLING SYSTEM 14
81
14.1 Cooling system
F03030-10
The water pump
1
in the engine forces the coolant to flow.
The pressure resulting from the warming of the cooling system is regu-
lated by a valve in the radiator cap
2
. This ensures that operating the
vehicle at the specified coolant temperature will not result in a risk 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.
14.2 Checking the antifreeze and coolant level
Warning
Danger of scalding During motorcycle operation, the coolant gets very hot and is under pressure.
–
Do not open the radiator, the radiator hoses or other cooling system components if the engine or the cooling
system are at operating temperature.
– Allow the cooling system and the engine to cool down before you open the radiator, the radiator hoses or
other components of the cooling system.
– In the event of scalding, rinse the area affected immediately with lukewarm water.
Warning
Danger of poisoning Coolant is toxic and a health hazard.
– Keep coolant out of the reach of children.
– Do not allow coolant to come into contact with the skin, the eyes and clothing.
– Consult a doctor immediately if coolant is swallowed.
– Rinse the affected area immediately with plenty of water in the event of contact with the skin.

– Check the antifreeze in the coolant.
−25 … −45 °C (−13 … −49 °F)
» If the antifreeze in the coolant does not match the specified
value:
– Correct the antifreeze in the coolant.
