REMOVAL & INSTALLATION
See Figures 1, 2 and 3
This procedure requires the evacuating and recharging of the A/C refrigerant. An approved recycling/recovery machine is needed to do this. If you do not have the proper certification in addition to the necessary equipment, you must consult a certified professional to evacuate the system before you start the procedure, and recharge the system when the job is complete.
- Determine whether your particular A/C system uses R-12 or R-134a refrigerant. Most vehicles have identification stickers placed in the engine compartment and on certain components of the A/C system to alert you to which type of refrigerant is used.
- Have the A/C refrigerant properly evacuated using an approved recovery/recycling machine.
- Disconnect the negative battery cable.
- Remove the accessary drive belt(s). Inspect the condition of the drive belt(s) and replace if cracked or worn.
- Tag and remove the refrigeration line retaining bolts from the A/C compressor. Remove the lines and O-ring from the compressor. Discard the O-rings. Once removed, cap both the open line end and compressor end, if reinstalling the compressor, to prevent debris from entering the A/C system.
- Unfasten the compressor electrical harness.
- Loosen and remove the compressor retainer bolts.
- Remove the compressor from the vehicle.
- If you are reinstalling the compressor, drain the refrigerant oil from the compressor to determine the amount of clean oil needed when installing later. Rotate the pulley several times to get as much oil as possible.
- Add the exact amount of clean refrigerant oil to the compressor. If the compressor is new, read the directions that came with the unit to determine if it has oil added already.
- Position the A/C compressor to the bracket on the engine and secure in place with the four retainer bolts. Tighten the bolts to 22-30 ft. lbs. (30-40 Nm).
- Fasten the electrical harness to the compressor.
- Remove the plugs from the refrigerant lines and compressor, if reinstalling the old compressor, and attach the refrigerant lines to the compressor using new O-rings with a light coating of clean refrigerant oil. Tighten the line bolts to 13-17 ft. lbs. (17-23 Nm).
- Install the drive belt(s).
- Connect the negative battery cable.
- Charge the A/C using an approved recovery/recycling machine.
- Run the A/C system and check to make sure it functions correctly.
