AIR CONDITIONING (A/C) COMPRESSOR - 2.5L REMOVAL/INSTALLATION










CAUTION:If installing a new A/C compressor due to an internal failure of the old unit, carry out the following procedures to remove contamination from the A/C system. Failure to remove contamination from the A/C system, if present, will result in poor A/C performance and/or damage to the new A/C compressor and other components. If an A/C Flusher is available, carry out the air conditioning (A/C) system flushing general procedure. See Air Conditioning (A/C) System Flushing. If the A/C Flusher is not available, carry out the refrigerant system filtering following air conditioning (A/C) component installation general procedure. See Refrigerant System Filtering Following Air Conditioning (A/C) Compressor Installation. Install a new thermostatic expansion valve (TXV), as directed by the A/C flushing or filtering procedure.Install a new suction accumulator as directed by the A/C flushing or filtering procedure.
NOTE:Installation of a new receiver/drier is not required when repairing the A/C system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the receiver/drier.
NOTE:If installing a new A/C compressor, the A/C clutch disc and hub, A/C compressor pulley and A/C clutch field coil must be inspected and transferred from the old unit to the new unit if suitable for reuse.
1. With the vehicle in NEUTRAL, position it on a hoist. See Lifting.

2. Recover the refrigerant. See Discharging And Recovery.






3. Remove the RH lower engine splash shield.






4. Release the accessory drive belt tensioner and remove the drive belt from the A/C compressor pulley.

5. Disconnect the A/C clutch field coil electrical connector.

6. Remove the 3 A/C compressor bolts and lower the A/C compressor to allow access to the suction and discharge fitting nuts.

- To install, tighten to 25 Nm {2.5 kgf-m, 18 ft-lbf}.

CAUTION:Do not allow the A/C compressor to hang from the A/C lines or damage to the A/C lines can occur.
7. Remove the A/C compressor suction and discharge fitting nuts and disconnect the fittings.

- Discard the O-ring seals and gasket seals.
- To install, tighten to 15 Nm {1.5 kgf-m, 133 in-lbf}.

8. Remove the A/C compressor.

9. To install, reverse the removal procedure.

- Install new gasket seals and O-ring seals.
- If a new A/C compressor is to be installed, the clutch assembly must be transferred from the old unit to the new unit. See - Service and Repair.
- If not filtering the A/C system, lubricate the refrigerant system with the correct amount of clean PAG oil. See Refrigerant Oil Adding.

NOTE:If installing a new A/C compressor, transfer the shipping caps from the new A/C compressor to the old A/C compressor after the refrigerant oil has been measured.
10. Evacuate, leak test and charge the refrigerant system. See Air Conditioning (A/C) System Evacuation And Charging.
