15.1
Cooling system
M00787-10
Water pump
in the engine circulates the coolant.
The pressure resulting from the warming of the cooling system is regulated by a valve
in radiator cap
. 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 cool-
ing 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.
Warning
Danger of poisoning
Coolant is poisonous and a health hazard.
–
Coolant must not come into contact with the skin, eyes, or clothing. If contact occurs with the eyes, rinse with water imme-
diately and contact a physician. Immediately clean contaminated areas on the skin with soap and water. If fuel is swal-
lowed, contact a physician immediately. Change clothing that is contaminated with coolant. Keep coolant out of reach of
children.
Condition
The engine is cold.
