Recovering the refrigerant is the first step before you replace the A/C liquid hose/line. To work on the FWG fitting, use a M13 Hex wrench to unfasten the a/c line to the expansion valve first, remove the suction line block from the expansion valve, plug the suction line and move it out of harm's way, ensuring all the other lines, including the expansion valve and condenser fittings are capped or plugged. Neil Taylor explained to remove the liquid line fastener at the receiver/drier and then unscrew the short receiver/drier line if stock removal is called for. After that, get rid of the bracket fastener on the receiver/drier and remove the bracket from the strut panel, but as you do, remember to pull out the two plastic fasteners underneath. Release the fastener holding the liquid line at the condenser, remembering that the radiator upper crossmember prevents direct access and so has to be removed first. After removing the liquid line mounting clamp fastener near the service port, disconnect the liquid line fastener from the receiver/drier and take out the liquid line, always capping the fittings to keep moisture from getting into the refrigerant system. All bends in the refrigerant lines should be smooth and a minimum of ten times as large as the refrigerant tubing before being used for installation and the flexible lines should be routed at least 80 millimeters (3 inches) away from the exhaust manifold. Place the liquid line in the vehicle and then screw on the liquid line fitting to the receiver/drier; tighten the fastener to 13.6 Nm or 10 ft. lbs. Put the liquid line mounting clamp fastener near the service port, tighten it to 6.8 Nm (5 ft. lbs.) and then tighten the liquid line fastener at the condenser to 23 Nm (17 ft. lbs.). Fit the bracket from the receiver/drier to the strut panel, slide the short receiver/drier line into place and tighten its fastener to 13.6 Nm (10 ft. lbs.). Connect the a/c line to the expansion valve, then fasten the retaining bolt to 23 Nm (17 ft. lbs.). After all that, it's time to remove the refrigerant and put it back in the system.
