Suction Line

DESCRIPTION





The A/C suction line is serviced in two sections. The upper section of the A/C suction line (1) is the refrigerant line that carries refrigerant from the A/C evaporator to the A/C accumulator. The lower section of the A/C suction line (2) carries refrigerant from the A/C accumulator to the A/C compressor. The upper portion of the A/C suction line is only serviced as an assembly with the A/C liquid line (5).

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 lower A/C suction line and the A/C liquid/suction line assembly has no serviceable parts except for the rubber O-ring seals (3), metal gaskets (4) and the low side service port valve core. 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 lower A/C suction line and/or the A/C liquid/suction line assembly is removed.

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