Line-A/C Suction

NOTE: LHD model with 4.7L engine shown in illustration. 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).

CAUTION: Use only seals specified for the vehicle. Failure to use the correct seals will cause the refrigerant system connections to 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 and installed.

If the A/C suction line is found to be leaking or damaged, it must be replaced.
