Front Suction Line

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. Remove the nut that secures the intermediate suction line fitting to the stud on the front suction line tapping plate.
4. Disconnect the intermediate suction line fitting from the front suction line tapping plate.
5. Install plug in, or tape over the open suction line fitting and the front suction line tapping plate inlet port.
6. Disconnect the front suction line from the compressor and front evaporator valve.
7. Remove the seals from the open suction line fittings and discard.
8. Install plug in, or tape over the open suction line fittings, the compressor inlet port and the expansion valve ports.
9. Remove the front suction line from the engine compartment.
10. If necessary, remove the bolt that secures the compressor portion of the front suction line to the front suction line tapping plate, separate the front suction lines, remove and discard the seal and, plug in, or tape over the open suction line fittings.

INSTALLATION
1. If the compressor portion of the front suction line was separated from the front suction line tapping plate, remove plugs or tape from the suction line fitting, lubricate a new rubber O-ring seal with clean refrigerant oil and install the seal onto the suction line fitting and, install the bolt that secures the compressor portion of the front suction line to the front suction line tapping plate. Tighten the bolt to 5 N.m (45 in. lbs.).
2. Install the front suction line into the engine compartment.
3. Remove plugs or tape from the suction line fittings, the compressor inlet port and the expansion valve ports.
4. Lubricate new rubber O-ring seals with clean refrigerant oil and install the seals onto the suction line fittings.
5. Connect the front suction line to the compressor and front evaporator valve.
6. Remove plugs or tape from the intermediate suction line fitting and the front suction line tapping plate inlet port.
7. Lubricate a new rubber O-ring seal with clean refrigerant oil and install the seal onto the intermediate suction line fitting.
8. Connect the intermediate suction line fitting to the front suction line tapping plate.
9. Install the nut that secures the intermediate suction line fitting to the stud on the front suction line tapping plate. Tighten the nut to 10 N.m (89 in. lbs.).
10. Reconnect the battery negative cable.
11. Evacuate the refrigerant system.
12. Charge the refrigerant system.
