223002795 - E5020 ENGINE COOLING - DESCRIPTION (Climate control system, MY 2005)

The radiator and air conditioner condenser cooling system consists of two electric fans operated at two different speeds:- the first speed is activated at a first engine coolant temperature level and a certain air conditioning refrigerant fluid pressure;- the second speed is engaged at a higher temperature.The fans are operated by two relays in the engine compartment junction unit and a remote control switch near the fans.The supply line for the fan and the relay energizing circuit are protected by special fuses located in the above control unit.The fans can therefore only be activated with the key ON.
