Compressor Replacement

REMOVAL PROCEDURE

IMPORTANT: When replacing a failed compressor it will be necessary to inspect the expansion orifice tube for material build up. Clean or replace as necessary. Refer to Expansion (Orifice) Tube Replacement.




1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging.
2. Remove the drive belt.
3. Raise the vehicle. Refer to Lifting and Jacking the Vehicle.
4. Remove the right front wheelhouse splash shield. Refer to Front Fender Liner Replacement.
5. Disconnect the electrical connector from the compressor.
6. Remove the EVAP canister purge solenoid valve from the compressor mounting stud.




7. Remove the compressor hose assembly from the compressor.
8. Remove and discard the sealing washers.




9. Remove the bolts that hold the compressor to the oil pan.
10. Remove the compressor idler pulley bolts
11. Remove the compressor.

INSTALLATION PROCEDURE

IMPORTANT: NEW A/C compressors are shipped WITHOUT poly-alkylene glycol (PAG) oil.




1. If a new A/C compressor is being installed, add 60 ml (2 oz) of PAG oil to the compressor.




2. If reinstalling the OLD A/C compressor perform the following:
Drain, measure and record the amount of PAG oil from both the suction and discharge ports and the crankcase in the A/C compressor.
If the measured amount of PAG oil drained Is less than or equal to 60 ml (2 oz), add 60 ml (2 oz) of new, clean PAG oil to the A/C compressor. If the measured amount of PAG oil drained is greater than 60 ml (2 oz), add the same amount of new, clean PAG oil to the A/C compressor.

NOTE: Refer to Fastener Notice in Service Precautions.

3. Install the compressor crankcase oil drain bolt (1) to the replacement compressor

Tighten
Tighten the compressor crankcase oil drain bolt to 20 N.m (15 lb ft).

4. Install the compressor and loosely install the compressor to idler pulley bracket bolts.
5. Loosely install the oil pan to compressor bolts.

Tighten
5.1. Tighten the compressor-to-idler pulley bracket bolts to 50 N.m (37 lb ft).
5.2. Tighten the compressor-to-oil pan bolts to 50 N.m (37 lb ft).




6. Install NEW sealing washers on the compressor ports.
7. Install the compressor hose assembly.

Tighten
Tighten the hose bolt to 33 N.m (24 lb ft).




8. Connect the compressor electrical connector.
9. Install the EVAP canister purge solenoid valve to the compressor mounting stud.
10. Install the right front wheelhouse splash shield. Refer to Front Fender Liner Replacement.
11. Lower the vehicle.
12. Install the drive belt.
13. Evacuate and charge the refrigerant system. Refer to Refrigerant Recovery and Recharging.
