Cooling system

1
The water pump in the engine keeps the cooling liquid in circulation.
The cooling liquid is cooled by the air stream. Therefore, the cooling effect
is reduced when the traveling speed is reduced. Dirty radiators additionally
reduce the cooling effect.
A mixture of 40% anti freeze liquid and 60% water is used as coolant. How-
ever, the anti-freeze protection must be at least -25° C (-13° F). This mix-
ture offers anti-freeze protection but also good corrosion protection and
should therefore not be replaced by pure water.

COOLANT FOAMING
Pressure induced by heating of the coolant in the system is controlled by a
valve in the radiator cap 2 ; a water temperature rising up to 120° C (248° F)
is admissible, without fear of problems.
Checking coolant level
The coolant should be 10 mm (0.4 in) above the radiator fins when the
engine is cold (see illustr.). In the event of the coolant being drained, always
fill and bleed the system.
