To install:


CAUTION
If the A/C compressor is being replaced, be certain to adjust the refrigerant system oil level. Failure to properly adjust the refrigerant oil level will prevent the A/C system from operating as designed and can cause serious A/C compressor damage.


CAUTION
The A/C accumulator and the A/C liquid line must be replaced if an internal failure of the A/C compressor has occurred. Failure to replace the A/C accumulator and the A/C liquid line can cause serious damage to the replacement A/C compressor.


NOTE
When replacing multiple A/C system components, see the Refrigerant Oil Capacities chart to determine how much oil should be removed from the new A/C compressor.


NOTE
Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is disconnected. Failure to replace the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.

  1. If the A/C compressor is being replaced, 2.1 ounces (60 milliliters) of refrigerant oil must first be drained from the new A/C compressor. When replacing multiple A/C system components, see the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant system. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
  2.  
  3. Position the A/C compressor into the engine compartment.
  4.  
  5. Install the three bolts that secure the A/C compressor to the engine. Tighten the bolts to 18 ft. lbs. (25 Nm).
  6.  
  7. Remove the tape or plugs from the compressor ports and the refrigerant line fittings.
  8.  
  9. Lubricate new rubber O-ring seals with clean refrigerant oil and install them and new gaskets onto the refrigerant line fittings. 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.
  10.  
  11. Connect the A/C discharge line and the A/C suction line to the A/C compressor.
  12.  
  13. Install the nuts that secure the A/C suction and discharge lines to the A/C compressor. Tighten the nuts to 15 ft. lbs. (20 Nm).
  14.  
  15. Connect the engine wire harness to the control valve.
  16.  
  17. Install the accessory drive belt.
  18.  
  19. Install the splash shield onto the right side frame rail.
  20.  
  21. Lower the vehicle.
  22.  
  23. Reconnect the negative battery cable.
    CAUTION
    Do NOT run the engine with a vacuum pump in operation or with a vacuum present within the A/C system. Failure to follow this caution will result in serious A/C compressor damage.

  24.  
  25. Evacuate and charge the refrigerant system.
