Line-A/C Suction

DESCRIPTION





The A/C suction line (9) is the refrigerant line that carries refrigerant from the A/C evaporator to the A/C compressor. The A/C suction line includes the low side service port (6) and is secured to the A/C expansion valve (7) by the liquid line tapping plate (8). On models equipped with the rear heating-A/C system, the A/C suction line also includes an extension tube that connects the suction line to the underbody lines.

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.

The A/C suction line has no serviceable parts except for the rubber O-ring seals, low-side service port valve and cap. 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 must be replaced whenever the A/C suction line is disconnected.

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