Version without climate control

The control unit directly controls the operation of the radiator fan depending on the coolant temperature and whether or not there is a climate control system.

NOTE Since the temperature of the engine is measured by the appropriate sensor there is no longer a thermal contact on the radiator.

Version without climate control

There is an electric fan which switches on when the temperature of the coolant exceeds 95°C.
It switches off with a hystesis of 2°C around the temperature level.
