Rear

The suction line (3) is the refrigerant line that carries refrigerant from the rear A/C evaporator to the A/C compressor. The suction line is retained into the liquid line tapping block (4) by a plastic retainer. Models equipped with the rear heating-A/C system include an extension tube (5) that connects the suction line to the underbody line by use of a spring-lock type refrigerant line coupler (6) and a secondary retaining clip (2).

CAUTION: Use only O-ring seals specified for the vehicle. Failure to use the correct O-ring seal will cause the refrigerant system connections to leak.

The suction line has no serviceable parts except for the rubber O-ring seals. 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 suction line is removed and installed.

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