REMOVAL
Any kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire air conditioning system. Kinks and sharp bends reduce the
flow of refrigerant in the system. High pressures are produced in the refrigerant system when the air conditioning compressor is operating. Extreme
care must be exercised to make sure that each of the refrigerant system connections is pressure-tight and leak free.
1. Disconnect and isolate the battery negative cable.
2. Recover the refrigerant from the refrigerant system. Refer to: Heating and Air Conditioning, Refrigerant, Service and Repair, Refrigerant -
Recovery, See: Refrigerant/Service and Repair/Refrigerant - Recovery
3. Remove the screw that secures the front liquid line block fitting to the inlet of the filter-drier, and disengage the fitting from the filter-drier. Install
plugs in, or tape over all of the opened refrigerant line fittings.
4. Disconnect the front liquid line refrigerant line coupler at the condenser outlet. Install plugs in, or tape over all of the opened refrigerant line
fittings.
5. Remove the front liquid line from the engine compartment.
6. Disconnect the wiring connector from the Pressure Transducer on the rear liquid line.
7. Remove the screw that secures the rear liquid line to the outlet of the filter-drier and disengage the fitting from the filter-drier. Install plugs or tape
over the opened refrigerant line fittings.
8. Remove the screw from the rear liquid line fitting at the expansion valve. Plug or tape over the opened refrigerant line fittings.
9. Remove the rear liquid line from the vehicle.

1. Remove the tape or plugs from the refrigerant line fittings on the front liquid line and the condenser outlet. Connect the front liquid line to the
condenser outlet.
2. Remove the tape or plugs from the front liquid line block fitting and the filter-drier inlet. Install the front liquid line block fitting to the filter-drier
inlet and secure the connection with a screw. Tighten the mounting screw to 13.5 Nm (120 in. lbs.).
3. Install the rear liquid line into the vehicle.
4. Remove any plugs or tape installed over the connections.
5. Install the rear liquid line to the expansion valve.
6. Install the rear liquid line to the filter-drier and secure the screw. Tighten the screw to 13.5 Nm (120 in. lbs.).
7. Connect the wiring connector to the Pressure Transducer on the rear liquid line.
8. Connect the battery negative cable.
9. Evacuate the refrigerant system. Refer to: Heating and Air Conditioning, Refrigerant, Service and Repair, Refrigerant - Evacuate, See:
Refrigerant/Service and Repair/Refrigerant - Evacuate
10. Charge the refrigerant system. Refer to: Heating and Air Conditioning, Refrigerant, Service and Repair, Refrigerant - Charge, See:
