The radiator and air conditioner condenser cooling system consists of an electric fan operated at two different speeds:

  • the first speed is activated at an initial engine coolant temperature level or a certain air conditioning refrigerant fluid pressure;
  • the second speed is engaged at a higher temperature or pressure.
The activation of the fan at two different speeds (slow and fast) is achieved by means of two dedicated relays located in the engine compartment junction unit.The fan supply lines are protected by two dedicated fuses located in the engine compartment junction unit.
