The radiator and condenser cooling system consists of an electric fan, for versions with air conditioning, 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 fan is operated by means of two specific relays located near the engine compartment junction unit.The fan supply line and relay excitation circuit is protected by a dedicated fuse located in the above control unit that protects many other ignition-operated services.The fan can therefore only be activated with the key ON.
