    • The overload protection takes over when the rubber element on the belt pulley loosens because the torque is excessive (for example, if the A/C compressor runs with resistance) and the belt pulley runs freely without driving the A/C compressor.
      NOTE:

      Under certain conditions (for example, rough engine idle), rubber element of pulley can disengage without a malfunction existing at compressor or in refrigerant circuit.

  5. A/C Compressor
    • Clean the A/C compressor driveshaft before setting the belt pulley on it
