LINE-A/C SUCTION

REMOVAL

WARNING: REFER TO THE APPLICABLE WARNINGS AND CAUTIONS FOR THIS SYSTEM BEFORE PERFORMING THE FOLLOWING OPERATION. FAILURE TO FOLLOW THE WARNINGS AND CAUTIONS COULD RESULT IN POSSIBLE PERSONAL INJURY OR DEATH.

NOTE: LHD model shown in illustrations. RHD model similar.




1. Disconnect and isolate the negative battery cable.
2. Recover the refrigerant from the refrigerant system.
3. If servicing the rear section of the A/C suction line (9), proceed to Step 4. If servicing only the front section of the A/C suction line (11), go to Step 10.
4. Disconnect the wire lead and connector (3) from the A/C low pressure switch (2) and remove the switch from the A/C accumulator (10).
5. Remove the two nuts (7) that secure the accumulator bracket (8) to the dash panel (5).
6. On LHD models, remove the secondary retaining clip (4) from the suction line spring-lock coupler and using the proper A/C line disconnect tool, disconnect the rear section of the A/C suction line (9) from the evaporator outlet tube (6).
7. On RHD models, remove the nut that secures the rear section of the A/C suction line to the A/C evaporator and disconnect the line from the evaporator.
8. Remove the nut (1) that secures the rear section of the A/C suction line to the A/C accumulator and disconnect the line from the accumulator.
9. Remove and discard the O-ring seals and install plugs in, or tape over the opened refrigerant line fittings and the accumulator and evaporator ports.
10. Remove the nut (1) that secures the front section of the A/C suction line (11) to the A/C accumulator (10) and disconnect the line from the accumulator and remove and discard the O-ring seal.




11. Remove the nut (1) that secures the front section of the A/C suction line (2) to the A/C compressor (3) and disconnect the line from the compressor.
12. Remove and discard the O-ring seals and install plugs in, or tape over the opened refrigerant line fittings and the accumulator and compressor ports.

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.
- LHD model shown in illustrations. RHD model similar.




1. Position the front section of the A/C suction line (2) into the engine compartment.
2. Remove the tape or plugs from the opened refrigerant line fittings and the accumulator and compressor ports.
3. Lubricate new rubber O-ring seals with clean refrigerant oil and install them on the refrigerant 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 front section of the A/C suction line to the A/C compressor (3) and install the retaining nut (1) Tighten the nut to 12 N.m (105 in. lbs.).




5. Connect the front section of the A/C suction line (11) to the A/C accumulator (10) and install the retaining nut (1). Tighten the nut to 12 N.m (110 in. lbs.).
6. If servicing the front section of the A/C suction line only, go to Step 14.
7. Remove the tape or plugs from all of the opened refrigerant line fittings and the accumulator and evaporator ports.
8. Lubricate new rubber O-ring seals with clean refrigerant oil and install them onto the refrigerant line fittings. Use only the specified O-rings 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.
9. Connect the rear section of the A/C suction line (9) to the A/C accumulator and install the retaining nut. Tighten the nut to 12 N.m (110 in. lbs.).
10. On LHD models, connect the spring-lock coupler that secures the rear section of the A/C suction line to the evaporator outlet tube (6) and install the secondary retaining clip (4).
11. On RHD models, connect the rear section of the A/C suction line to the A/C evaporator and install the retaining nut. Tighten the nut to 12 N.m (110 in. lbs.).
12. Install the two nuts (7) that secure the accumulator bracket to the dash panel (5). Tighten the nuts to 4.5 N.m (40 in. lbs.).
13. Connect the wire lead and connector (3) to the A/C low pressure switch (2).
14. Reconnect the negative battery cable.
15. Evacuate the refrigerant system.
16. Charge the refrigerant system.
