DESCRIPTION






NOTE: LHD model with 4.7L engine shown. RHD model and other engines similar.

The A/C suction line (1) is the refrigerant line that carries refrigerant from the A/C evaporator, through the A/C expansion valve (2), to the A/C compressor (3). The A/C suction line includes the low side service port (4).

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 O-ring and dual plane seal, low-side service port valve and protective cap. The seals used on the connections are made from a special type of rubber not affected by R-134a refrigerant. The seals must be replaced whenever the A/C suction line is removed.

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