Removal & Installation

Print


CAUTION
Refer to the applicable warnings and cautions for this system before performing the following operation. Failure to follow the warnings and cautions may result in serious or fatal injury.


NOTE
The A/C compressor may be removed and repositioned without discharging the refrigerant system or disconnecting the refrigerant lines in order to service other engine components.

  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Disconnect and isolate the negative battery cable.
  4.  
  5. Recover the refrigerant from the refrigerant system. Refer to Maintenance, Discharging The System.
  6.  
  7. Raise and safely support the vehicle.
  8.  
  9. Remove the splash shield from the right side frame rail.
  10.  
  11. Remove the accessory drive belt. Refer to Accessory Drive Belts, removal & installation.
  12.  
  13. If equipped with the 5SE12 A/C compressor, disconnect the engine wire harness (1) from the compressor control valve (2).
    WARNING
    If equipped with the 6SEU16 A/C compressor, be sure to disconnect the tie strap that secures the control valve wire lead to the engine wire harness prior to removing the compressor. Failure to disconnect the tie strap may result in damage to the wire harness, wire lead, and A/C compressor.

  14.  
  15. If equipped with the 6SEU16 A/C compressor, disconnect the tie strap that secures the compressor control valve wire lead to the engine wire harness and disconnect the wire lead from the harness.
  16.  
  17. Remove the nuts (4) that secure the A/C discharge line (5) and the A/C suction line (6) to the A/C compressor (3).
  18.  
  19. Disconnect the A/C discharge and suction lines from the A/C compressor and remove and discard the O-ring seals and gaskets.

To install:


WARNING
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.


WARNING
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.


NOTE
The 5SE12 A/C compressor is shown in illustrations.

  1. If the A/C compressor (1) is being replaced, some refrigerant oil must first be drained from the new A/C compressor. If equipped with the 5SE12 A/C compressor, drain 2.4 oz (70 milliliters) of refrigerant oil from the new compressor. If equipped the 6SEU16 A/C compressor, drain 2 oz (60 milliliters) of refrigerant oil from the new 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 3 bolts (2) 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 (5) and the A/C suction line (6) to the A/C compressor (3).
  12.  
  13. Install the nuts (4) 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. If equipped with the 5SE12 A/C compressor, connect the engine wire harness (1) to the compressor control valve (2).
    WARNING
    If equipped with the 6SEU16 A/C compressor, be sure to correctly route the control valve wire lead up to the engine wire harness and install the tie strap. Failure to install the tie strap could result in damage to the wire harness, wire lead, and compressor.

  16.  
  17. If equipped with the 6SEU16 A/C compressor, connect the control valve wire lead connector to the engine wire harness and install tie strap that secures the wire lead to the engine harness.
  18.  
  19. Install the accessory drive belt. Refer to Accessory Drive Belts, removal & installation.
  20.  
  21. Install the splash shield onto the right side frame rail.
  22.  
  23. Lower the vehicle.
  24.  
  25. Connect the negative battery cable.
