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 malfunc-
tions.
110 °C (230 °F)
The coolant is cooled by the air stream and a radiator fan
which is activated at high temperature.
The lower the speed, the less the cooling effect. Dirty cooling fins
also reduce the cooling effect.

speed is limited.
