How to remove compressor on Dodge Durango ?

3.7L & 4.7L Engines



The compressor may be removed and repositioned without disconnecting the refrigerant lines or discharging the refrigerant system. Discharging is not necessary if servicing the compressor clutch or clutch coil, the engine, the cylinder head, or the generator.


NOTE
See illustration for parts reference.

  1. Recover the refrigerant from the refrigerant system.
  2. Disconnect and isolate the negative battery cable.
  3. Remove the accessory drive.
  4. Disconnect the wire harness connector from the A/C compressor clutch coil.
  5. Remove the nuts that secure the A/C suction line and A/C discharge line to the A/C compressor.
  6. Disconnect the A/C suction and discharge lines from the A/C compressor and remove and discard the O-ring seals and gaskets.
  7. Install plugs in, or tape over, the opened refrigerant line fittings and compressor ports.
  8. Remove the bolts (1, 2, and 3) that secure the A/C compressor (4) to the mounting bracket (6).
  9. Remove the A/C compressor from the engine compartment.

    Install bolt (1) and hand tighten.
    Tighten bolt (3) to 40 Nm (30 ft. lbs.).
    Tighten bolt (2) to 55 Nm (41 ft. lbs.).
    Tighten bolt (1) to 55 Nm (41 ft. lbs.).

  3. Remove the tape or plugs from the opened suction line fitting (2) and the discharge line fitting (3) and the compressor ports (4).
  4. Lubricate new rubber O-ring seals with clean refrigerant oil and install them and new gaskets onto the suction and the discharge line fittings.
    NOTE
    Use only the specified O-rings as they are made of a special material for the R-134a system. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.

  5. Install the A/C suction and discharge lines onto the A/C compressor.
  6. Install the nuts (1) that secure the suction and discharge lines to the A/C compressor. Tighten the nuts to 23 Nm (17 ft. lbs.).
