5. Using the proper A/C line disconnect tool, disconnect the suction line from the A/C evaporator and remove and discard the O-ring seal.
6. Install plugs in, or tape over the opened suction line fitting and the evaporator port.
7. Remove the nuts that secure the suction lines to the accumulator and to the A/C compressor.
8. Disconnect the suction lines from the accumulator and the A/C compressor.
9. Install plugs in, or tape over the opened suction line fittings and the accumulator and compressor ports.
10. Remove the suction lines from the vehicle.

INSTALLATION

NOTE: Replacement of the refrigerant line O-ring seals is required anytime a refrigerant line is opened. Failure to replace the rubber O-ring seals could result in a refrigerant system leak.

1. Position the A/C suction line into the engine compartment, as required.
2. Remove the tape or plugs from the opened suction line fittings and the A/C accumulator, A/C compressor and A/C evaporator as required.
3. Lubricate new rubber O-ring seals with clean refrigerant oil and install them on the suction line fittings. Use only the specified O-ring seals as they are made of a special material for the R-134a system. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
4. Connect the suction lines onto the A/C accumulator and A/C compressor, as required.
5. Install the nuts that secure the suction lines to the accumulator. Tighten the nuts to 9 N.m (80 in. lbs.).
6. Install the nut that secures the suction line to the A/C compressor. Tighten the nut to 25 N.m (18 ft. lbs.).
7. Connect the suction line spring-lock coupler to the A/C evaporator.
8. Install the secondary retaining clip onto the spring-lock coupler that secures the suction line to the A/C evaporator.
9. Install the suction line into the retaining clip located near the accumulator.
10. Reconnect the negative battery cable.
11. Evacuate the refrigerant system.
12. Charge the refrigerant system.
