Cooling system

The water pump in the engine circulates the cooling liquid. However, the
cooling liquid can only circulate properly if the cooling circuit contains no air
bubbles.
Bleeding of the cooling system is therefore required
a) after adding more than 0.25 l cooling liquid and
b) after refilling the entire cooling system.
(see Bleeding the cooling system).

Some models are equipped with a thermostat
its operating temperature more quickly. When the engine is cold, the liquid
coolant circulates in the cylinder and the cylinder head. As soon as the coo-
ling liquid has reached a temperature of approximately 55°C, the ther-
mostat opens and the cooling liquid is also pumped through the two alumi-
num radiators.
The cooling liquid is cooled by the air stream. This means that the cooling
effect decreases with the travelling speed. Dirty radiators additionally
reduce the cooling effect.

A mixture of 40% anti freeze liquid and 60% water is used as coolant.
However, the anti-freeze protection must be at least -25° C (-13° F). This
mixture offers anti-freeze protection but also good corrosion protection and
should therefore not be replaced by pure water.
