15 COOLING SYSTEM 132
15.1 Cooling system
B00765-10
Water pump 1 in the engine circulates 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 malfunctions.
