AIR CONDITIONING (A/C) COMPRESSOR
Removal and Installation
CAUTION: If installing a new air conditioning compressor due to an internal failure of the old unit, you must carry out the following procedures to remove contamination from the air conditioning system.
- If A/C flushing equipment is available, carry out flushing of the air conditioning system prior to installing a new air conditioning compressor.
- If A/C flushing equipment is not available, carry out filtering of the air conditioning system after a new air conditioning compressor has been installed.
- Install a new evaporator core orifice, 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 suction accumulator is not required when repairing the air conditioning system except when there is physical evidence of contamination from a failed A/C compressor or damage to the suction accumulator.
1. With the vehicle in NEUTRAL, position it on a hoist.
2. If flushing of the air conditioning system has not been carried out, recover the refrigerant.
3. Remove the cooling fan motor and shroud.
4. Remove the bolts and the drive belt cover.
5. Remove the drive belt from the A/C compressor pulley.
6. Disconnect the field coil electrical connector.
7. Remove the bolts and position aside the power steering line.
- To install, tighten to 13 Nm (10 lb-ft).
8. Remove the 3 compressor bolts and lower the A/C compressor.
9. Loosen the compressor manifold bolt and remove the A/C compressor.
- Discard the O-ring seals.
- To install, tighten to 21 Nm (15 lb-ft).
10. To install, reverse the removal procedure.
- If a new A/C compressor is to be installed, the clutch and clutch field coil must be transferred from the old unit to the new unit.
- If filtering of the refrigerant system is not to be carried out, lubricate the refrigerant system with the correct amount of clean PAG oil.
11. If filtering of the refrigerant system is not to be carried out, evacuate, leak test and charge the refrigerant system.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
