Cooling system

The water pump

in the engine forces the coolant to flow.
The pressure resulting from the warming of the cooling system is regulated by a valve in the
radiator cap . The specified coolant temperature is therefore permissible without danger of
function problems.
120 °C (248 °F)
Cooling is effected by the air stream. The radiator fan provides extra cooling.
The lower the speed, the less the cooling effect. Dirty cooling fins also reduce the cooling
effect.
