A/C Compressor: Installation

WARNING: This page is about a different car, the 2003 Dodge Intrepid, 2003 Chrysler Intrepid, 2003 Chrysler Concorde, and 2003 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: REVIEW THE WARNING AT THE BEGINNING OF THIS ARTICLE BEFORE PERFORMING THE FOLLOWING OPERATION. (Refer to WARNING  ).

Any kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire air conditioning system. Kinks and sharp bends reduce the flow of refrigerant in the system. A good rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times the diameter of the hose. In addition, the flexible hose refrigerant lines should be routed so they are at least 80 millimeters (3 inches) from the exhaust manifold. (Whenever possible).

High pressures are produced in the refrigerant system when the air conditioning compressor is operating. Extreme care must be exercised to make sure that each of the refrigerant system connections is pressure-tight and leak free. It is a good practice to inspect all flexible hose refrigerant lines at least once a year to make sure they are in good condition and properly routed.

NOTE: If a replacement compressor is being installed, be certain to check the refrigerant oil level. (Refer to STANDARD PROCEDURE  ). Use only refrigerant oil of the type recommended for the compressor in the vehicle. (Refer to DESCRIPTION  ).
  1. Position the a/c compressor in the vehicle and install the attaching bolts. Torque the a/c compressor mounting bolts to 28 N.m (21 ft. lbs.)
  2. Remove the plug or cap from the opened refrigerant line fittings. Install new O-rings and lubricate with refrigerant oil. Install the suction line and discharge line fittings to the manifold on the a/c compressor. Tighten the fasteners to 23 N.m (17 ft. lbs.).
  3. Install the drive belts (Refer to ACCESSORY DRIVE ).
  4. Connect the a/c compressor clutch coil wire lead.
  5. Connect the negative battery cable remote terminal from the remote battery post.
  6. Evacuate the refrigerant system. (Refer to STANDARD PROCEDURE - REFRIGERANT SYSTEM EVACUATE  ).
  7. Charge the refrigerant system. (Refer to REFRIGERANT SYSTEM CHARGE  ).
