Air Conditioning (A_C) Compressor

• If A/C flushing equipment is available, carry out the A/C system flushing procedure prior to installing a new A/C compressor. For additional information, refer to Section 412-00.
• If A/C flushing equipment is not available, carry out the refrigerant system filtering procedure following A/C compressor installation. For additional information, refer to Section 412-00.
• Install a new Thermostatic Expansion Valve (TXV) , as directed by the A/C flushing or filtering procedure.
• Install a new receiver/drier as directed by the A/C flushing or filtering procedure.

Installation of a new receiver/drier is not required when repairing the A/C system, except when there is physical evidence of contamination from a failed A/C compressor or damage to the receiver/drier. Damage to the receiver/drier includes leaks in the receiver/drier, physical damage to the receiver/drier shell or desiccant, or moisture contamination. Moisture contamination results only from a complete loss of refrigerant, and equalization of the refrigerant system pressure with atmospheric pressure for a period longer than one hour. If even a slight amount of positive refrigerant pressure is present, and physical evidence of contamination from an A/C compressor failure is not present in the system before repairs are carried out, a new receiver/drier should not be installed.

1. 1
   With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Section 100-02.
2. 2
   Recover the refrigerant. For additional information, refer to Section 412-00.
3. 3
   NOTE: The A/C compressor discharge line is held in place by a bracket attached to the lower rear A/C compressor stud-bolt. The A/C compressor discharge fitting cannot be easily disconnected until later in this procedure when the bracket is detached.

   Remove the A/C compressor suction and discharge fitting nuts and disconnect the suction fitting.

   • Discard the O-ring seal and gasket seal.

   • To install, tighten to 15 N·m.

4. Remove the engine cooling fan assembly. For additional information, refer to Section 303-03.

5. Remove the lower radiator air deflector. For additional information, refer to Section 501-02.

1. 1
   Remove the 2 drive belt shield bolts and remove the shield.
2. 2
   Release the tensioner and remove the drive belt from the A/C compressor pulley.

1. 1
   Remove the power steering line bracket nut at the transmission.

   • To install, tighten to 9 N·m.
2. 2
   Remove the compressor-to-condenser discharge line bracket nut from the lower rear A/C compressor stud-bolt and detach the discharge line and power steering line brackets.

   • To install, tighten to 9 N·m.
3. 3
   Disconnect the A/C compressor discharge fitting.

   • Discard the O-ring seal and gasket seal.
4. 4
   Disconnect the clutch field coil electrical connector.
5. 5
   Remove the 2 A/C compressor bolts and the A/C compressor stud-bolt.

   • To install, tighten to 25 N·m.
6. 6
   Remove the A/C compressor.
7. 7
   To install, reverse the removal procedure.

   • Install new gasket seals and O-ring seals.

   • Lubricate the refrigerant system with the correct amount of clean PAG oil. For additional information, refer to Section 412-00.
8. 8
   Evacuate, leak test and charge the refrigerant system. For additional information, refer to Section 412-00.
