Fig. 246: Liquid/Suction Line Assembly with Rear A/C

NOTE: A/C liquid and suction line assembly with rear A/C shown. Front A/C only line assembly similar.

The A/C liquid line is serviced in two sections. The front section of the A/C liquid line is the refrigerant line that carries liquid refrigerant from the A/C condenser to the A/C receiver/drier and is only serviced as an assembly with receiver/drier. The rear section of the A/C liquid line (1) carries liquid refrigerant from the A/C receiver/drier to the A/C expansion valve and includes the high side service port (2) and a fitting for the A/C pressure transducer (4). The rear section of the A/C liquid line is only serviced as an assembly with the A/C suction line (5). When equipped with rear A/C, the A/C liquid and suction line assembly includes connections for the underbody refrigerant lines (3).

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.

The A/C liquid and suction line assembly has no serviceable parts except for the metal gaskets, rubber O-ring seals and the service port valve cores. The O-ring seals used on the connections are made from a special type of rubber not affected by R-134a refrigerant. The O-ring seals and gaskets must be replaced whenever the A/C liquid/suction line assembly is disconnected.

The A/C liquid and suction line assembly cannot be repaired and must be replaced if leaking or damaged.
