2889362 - E5020 ENGINE COOLING - Description (Heater)
Description
The engine radiator cooling system
consists of a fan which operates at two different speeds:
- the first speed is activated at a first coolant temperature
level;
- the second speed cuts in at a higher temperature threshold.
The fan is operated 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 a fuse which protects
numerous other services controlled by the ignition.The fan therefore only comes on when the
ignition is switched ON.
