Air Conditioning (AC) Compressor

The A/C  compressor has the following characteristics:

• A non-serviceable shaft seal.
• A pressure relief valve installed in the rear of the compressor to protect the refrigerant system against excessively high refrigerant pressures.
• The A/C  compressor uses PAG oil or equivalent. This oil contains special additives required for the A/C  compressor.
• The A/C  compressor oil may have some slightly dark-colored streaks while maintaining normal oil viscosity. This is normal for this A/C  compressor because of break-in wear that can discolor the oil.
• Use the oil adding procedure specified for this vehicle when installing a new A/C  compressor. REFER to Refrigerant Oil Adding .
