Sidewall Refrigerant Lines

REMOVAL
The rear refrigerant lines for the optional rear A/C system is serviced in four sections. The liquid line for the optional rear A/C system uses a spring-lock refrigerant line coupler which requires the use of a 3/8 inch quick-disconnect tool (part of Special Tool, A/C Line Disconnect Kit 7193).

WARNING: REVIEW THE WARNINGS AND CAUTIONS IN THE FRONT OF THIS SECTION BEFORE PERFORMING THE FOLLOWING OPERATION.

1. Recover the refrigerant from the refrigerant system.
2. Disconnect and isolate the battery negative cable.
3. Disconnect the suction line from the rear expansion valve outlet port.
4. Disconnect the liquid line from rear solenoid valve inlet port.
5. Remove the seals from the open liquid and suction line fittings and discard.
6. Install plugs in, or tape over the open liquid and suction line fittings and, the rear solenoid and expansion valve ports.
7. Remove the interior trim panel from the right quarter panel.
8. Disconnect the fittings that secure the rear refrigerant lines to the sidewall refrigerant lines.
9. Remove the seals from the open liquid and suction line fittings and discard.
10. Install plugs in, or tape over the open liquid and suction line fittings.
11. Remove the bolts that secure the two refrigerant line retaining blocks to the vehicle sidewall.
12. Carefully pull the rubber refrigerant lines out from the sidewall.
13. Remove the sidewall section of the rear refrigerant lines from the vehicle.

INSTALLATION
1. Install the sidewall section of the rear refrigerant lines to the vehicle.
2. Carefully route the rubber refrigerant lines through the sidewall.
3. Install the bolts that secure the two refrigerant line retaining blocks to the vehicle sidewall. Tighten the bolts to 5 N.m (45 in. lbs.).
4. Remove plugs or tape from the open rear and sidewall refrigerant line fittings.
5. Lubricate new rubber O-ring seals with clean refrigerant oil and install the seals onto the rear-to-sidewall refrigerant line fittings.
6. Connect the fittings that secure the rear refrigerant lines to the sidewall refrigerant lines. Tighten the liquid line fitting to 16 N.m (142 in. lbs.). Tighten the suction line fitting to 30 N.m (22 ft. lbs.).
7. Install the interior trim panel from the right quarter panel.
8. Remove plugs or tape from the open sidewall liquid and suction line fittings and, the rear solenoid and expansion valve ports.
9. Lubricate new rubber O-ring seals with clean refrigerant oil and install the seals onto the sidewall refrigerant line fittings.
10. Connect the liquid line to the rear solenoid valve inlet port.
11. Connect the suction line to the rear expansion valve outlet port and reinstall the rear A/C evaporator panel and duct.
12. Connect the battery negative cable.
13. Evacuate the refrigerant system.
14. Charge the refrigerant system.
