2889366 - E5020 ENGINE COOLING - Description (Euro 3)
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
other services.The fan therefore only comes on when the
ignition is switched ON.
