2889370 - E5020 ENGINE COOLING - Description (GPOWER, Euro 3, BIPOWER, BLUPOWER)

Description

The engine radiator and air conditioner condenser cooling system consists of one fan operated at two different speeds.

• the first speed is activated at a first coolant temperature level or at a certain air conditioner coolant pressure.
• the second speed cuts in at a higher temperature or pressure threshold.

The operation of the fan is achieved by means of two special relays located in the relay and fuse box in the engine compartment.The fan supply line is protected by a special maxifuse, located next to the above mentioned box, whilst the circuit for energizing the relays is protected by the fuse which protects numerous other services controlled by the ignition.The fan therefore only comes on when the ignition is switched ON.
