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.
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. It is a good practice to inspect all flexible hose refrigerant lines at least
once a year to make sure they are in good condition and properly routed.
WARNING: REVIEW THE WARNINGS AND CAUTIONS BEFORE PERFORMING THE FOLLOWING OPERATION.
REMOVAL
1. Disconnect and isolate the battery negative cable.
2. Recover the refrigerant from the refrigerant system. Refer to: Heating and Air Conditioning, Service and Repair, Refrigerant Recovery, See:
Heating and Air Conditioning/Service and Repair/Refrigerant Recovery
Liquid Line Remove/Install
3. Disconnect the liquid line and/or liquid line jumper refrigerant line couplers at the evaporator inlet and the liquid line jumper, or at the condenser
outlet and the liquid line jumper. See Refrigerant Line Coupler from the procedures. Install plugs in, or tape over all of the opened refrigerant line
fittings.
4. Remove the liquid line and/or liquid line jumper from the vehicle.
INSTALLATION
1. Remove the tape or plugs from the opened refrigerant line fittings on the condenser outlet tube, the liquid line, the evaporator inlet, and/or the
liquid line jumper. Connect the liquid line to the evaporator inlet tube and the liquid line jumper, and/or connect the liquid line jumper to the liquid
line and the condenser outlet tube.
2. Connect the battery negative cable.
3. Evacuate the refrigerant system. Refer to: Heating and Air Conditioning, Service and Repair, Refrigerant System Evacuate, See: Heating
and Air Conditioning/Service and Repair/Refrigerant System Evacuate
4. Charge the refrigerant system. Refer to: Heating and Air Conditioning, Service and Repair, Refrigerant System Charge, See: Heating and
Air Conditioning/Service and Repair/Refrigerant System Charge
