A/C Suction Hose/Line Replacement

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. A good rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times the diameter of the hose. In addition, the flexible hose refrigerant lines should be routed so they are at least 80 millimeters (3 inches) from the exhaust manifold.
1. Disconnect and isolate the battery negative cable.
2. Recover the refrigerant from the refrigerant system.

3. Unplug the wire harness connector from the high pressure cut-off switch.

4. Remove the fastener and disengage the discharge line fitting from the condenser inlet tube. Install plugs in, or tape over all of the opened refrigerant line fittings.
5. Remove the fastener and disengage the suction line from the accumulator outlet tube refrigerant line fitting. Install plugs in, or tape over all of the opened refrigerant line fittings.
6. Remove the fasteners that secure the suction and discharge lines to the compressor. Install plugs in, or tape over all of the opened refrigerant line fittings.
7. Remove the suction and discharge lines from the vehicle.

1. Remove the tape or plugs from the suction and discharge line manifold and the compressor. Install the suction and discharge line manifold to the compressor. Tighten the mounting screw to 22 Nm (200 in. lbs.).
2. Remove the tape or plugs from the refrigerant line fittings on the suction line and the accumulator outlet tube. Connect the suction line to the accumulator outlet tube refrigerant line coupler.
3. Remove the tape or plugs from the refrigerant line fittings on the discharge line and the condenser inlet tube. Connect the discharge line refrigerant line coupler to the condenser inlet tube.
4. Install the bolt that secures the discharge line support bracket to the compressor. Tighten the bolt to 28 Nm (21 ft. lbs.).
5. Plug in the wire harness connector to the high pressure cut-off switch.
6. Connect the battery negative cable.
7. Evacuate the refrigerant system.
8. Charge the refrigerant system.
