COOLING SYSTEM 17
195
17.1 Cooling system
E01111-10
Water pump
1
in the engine ensures forced circulation of the
coolant.
The pressure resulting from the warming of the cooling system is
regulated 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 malfunc-
tions.
110 °C (230 °F)
H02680-10
The coolant is cooled by the air stream and a radiator fan
4
,
which is activated at high temperature.
The lower the speed, the less the cooling effect. Dirty cooling fins
also reduce the cooling effect.
Info
If the cooling system overheats, the maximum engine
speed is limited.
