Suction Line: Installation

WARNING: This page is about a different car, the 2005 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.

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

Position the A/C suction line(s) into the engine compartment, as required.
Remove the tape or plugs from the opened suction line fittings and the A/C accumulator, A/C compressor and A/C evaporator as required.
Lubricate new rubber O-ring seals with clean refrigerant oil and install them on the suction line fittings. Use only the specified O-ring seals 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.
Connect the A/C suction line onto the A/C evaporator, A/C accumulator and A/C compressor, as required.
If required, install the bolt or nut (depending on engine application) that secures the A/C suction line to the A/C compressor. Tighten the bolt or nut to 28 N.m (20 ft. lbs.).
If required, install the nut that secures the A/C suction line to the evaporator tapping block. Tighten the nut to 23 N.m (17 ft. lbs.).
As required, install the nut(s) that secures the A/C suction line to the A/C accumulator. Tighten the nut(s) to 9 N.m (80 in. lbs.).
Reconnect the negative battery cable.
Evacuate the refrigerant system (Refer to HEATING & AIR CONDITIONING/PLUMBING - STANDARD PROCEDURE - REFRIGERANT SYSTEM EVACUATE) .
Charge the refrigerant system (Refer to HEATING & AIR CONDITIONING/PLUMBING - STANDARD PROCEDURE - REFRIGERANT SYSTEM CHARGE) .
