A/C Discharge Line: 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: Replace all O-rings and lubricate each with ND-8 PAG oil before installation of component.

Connect the discharge line at the A/C condenser. Tighten retainer bolt to 23 N.m (17 ft. lbs.).
Connect the discharge line at the compressor. Tighten retainer bolt to 23 N.m (17 ft. lbs.).
Install the a/c pressure transducer. (Refer to CONTROLS ).
Plug the harness connector into the a/c pressure transducer.
Connect the negative battery cable remote terminal to the remote battery post.
Evacuate the refrigerant system. (Refer to STANDARD PROCEDURE - REFRIGERANT SYSTEM EVACUATE ).
Charge the refrigerant system. (Refer toREFRIGERANT SYSTEM CHARGE ).
