Cooling system
Hot climates
In order to retain the corrosion protection and the
higher boiling point, it is essential to use coolant
consisting of water mixed with antifreeze and
corrosion inhibitor (ethylene glycol). This also
applies in countries where the temperature never
drops below 0°C (32°C).
The coolant should always contain 35-55% anti-
freeze and corrosion inhibitor by volume so that
the coolant properties ensure that the coolant
works correctly.
Topping up
Coolant must only be topped up with pre-mixed
coolant. The pre-mixed coolant can either be
concentrate mixed with clean freshwater or pre-
mixed coolant from the factory. Use only pure
fresh water that is free from particles, sludge and
other impurities.
Containers used for mixing coolant must be in-
tended for the purpose and free from any dirt or
contaminants. When the containers not in use
they must be kept closed to avoid collecting dirt
and dust.
Within the coolant change interval, coolant may
only be reused if it has been cleaned of dirt,
sludge and particles. If the coolant is contaminat-
ed with oil or fuel, it must not be reused.
