Cooling system
V02698-10
Water pump
1
in the engine ensures forced circulation of the coolant.
The pressure resulting from the warming of the cooling system is reg-
ulated by a valve in radiator cap
2
. Heat expansion causes excess
coolant to flow into compensating tank
3
. When the temperature
falls, this surplus coolant is sucked back into the cooling system. This
ensures that operating the vehicle at the specified coolant temperature
will not result in a risk of malfunctions.
125 °C (257 °F)
400407-10
The coolant is cooled by the air stream and radiator fan
4
, which is
activated depending on the temperature.
The lower the speed, the less the cooling effect. Dirty cooling fins also
reduce the cooling effect.
