The radiator and air conditioner condenser cooling system consists of two electric fans 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 comes on at a higher temperature or pressure.The activation of the fans is achieved by means of two specific relays located in the engine compartment junction unit and a third relay located on the duct for the actual fans.The supply line for the fans is protected by two special fuses, located in the engine compartment junction unit.
