The radiator and air conditioner condenser cooling system consists of two electric fans operated at two different speeds:- the first speed is activated at an intial engine coolant temperature level;- 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 supply line for the fan and the relay energizing circuit are protected by special fuses located in the engine compartment control unit.The fan can therefore only be activated with the key ON.
