Removal and Installation

WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

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.

If A/C flushing equipment is available, carry out flushing of the air conditioning system prior to installing a new air conditioning compressor. For additional information, refer to AIR CONDITIONING (A/C) SYSTEM FLUSHING .
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. For additional information, refer to REFRIGERANT SYSTEM FILTERING FOLLOWING AIR CONDITIONING (A/C) COMPRESSOR INSTALLATION .
Install a new evaporator core orifice. For additional information, refer to EVAPORATOR CORE ORIFICE .
Install a new suction accumulator. For additional information, refer to SUCTION ACCUMULATOR .

NOTE:

Installation of a new suction accumulator 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 suction accumulator.
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.

With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING & LIFTING .
Recover the A/C refrigerant. For additional information, refer to REFRIGERANT SYSTEM RECOVERY .
Remove the accessory drive belt from the A/C compressor pulley.
Disconnect the A/C clutch field coil electrical connector.
Remove the compressor manifold bolt and disconnect the compressor manifold and tube assembly.
- Discard the O-ring seals.
  - To install, tighten to 20 N.m (15 lb-ft).
Remove the A/C compressor nut and the 2 A/C compressor bolts.
- To install, tighten to 25 N.m (18 lb-ft).
Remove the A/C compressor.
If necessary, remove the A/C compressor mounting bracket.
To install, reverse the removal procedure.
- If a new A/C compressor is to be installed, the clutch assembly must be transferred from the old unit to the new unit. For additional information, refer to CLUTCH AND CLUTCH FIELD COIL .
- Install new O-ring seals.
- If not filtering the A/C system, lubricate the refrigerant system with the correct amount of clean PAG oil. For additional information, refer to REFRIGERANT OIL ADDING .
Evacuate, leak test and charge the refrigerant system. For additional information, refer to AIR CONDITIONING (A/C) SYSTEM RECOVERY, EVACUATION AND CHARGING .
