(All 125/150 models)
Water pump
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
. 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.
