600614-10
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 . Heat expansion causes excess coolant to flow into the compensating
tank . If the temperature falls, the excess coolant is sucked back into the cooling system.
The specified coolant temperature is therefore permissible without danger of function prob-
lems.
