Section 87 (HVAC Systems (Service Information)): Plumbing: Receiver/Drier-A/C: Installation

WARNING: This page is about a different car, the 2007 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system. See STANDARD PROCEDURE . 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 receiver/drier must be replaced if an internal failure of the A/C compressor has occurred. Failure to replace the A/C receiver/drier can cause serious A/C compressor damage.
NOTE: When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant system. See STANDARD PROCEDURE .
NOTE: If only the A/C receiver/drier is being replaced, add 30 milliliters (1 fluid ounce) of refrigerant oil to the refrigerant system. Use only the refrigerant oil of the type recommended for the A/C compressor in the vehicle.
NOTE: Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is opened. Failure to replace the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.

  4. Connect the A/C receiver/drier to the right end of the A/C condenser.
  5. Install the nut (6) that secures the A/C receiver/drier to the A/C condenser. Tighten the nut to 20 N.m (15 ft. lbs.).
  6. Install the screw (4) that secures the A/C receiver/drier to the radiator and fan shroud (5). Tighten the screw to 5 N.m (44 in. lbs.).
  7. Lubricate a new dual-plane seal with clean refrigerant oil and install it onto the A/C liquid line (2) Use only the specified seal as it is 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.
  8. Install the nut (1) that secures the A/C liquid line to the A/C receiver/drier. Tighten the nut to 20 N.m (15 ft. lbs.).
  9. Install the air cleaner housing and air intake tube.
  10. Install the grille. Refer to INSTALLATION .
  11. Reconnect the negative battery cable.
  12. Evacuate the refrigerant system. See STANDARD PROCEDURE .
  13. If the A/C receiver/drier is being replaced, add 30 milliliters (1 fluid ounce) of refrigerant oil to the refrigerant system. When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant system. See STANDARD PROCEDURE . Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
  14. Charge the refrigerant system. See STANDARD PROCEDURE .
