Start by evacuate and charge the A/C lines and conduct a leak test on them and drain the cooling system when repairing heater lines.

Use a tubing cutter to cut off the damaged line while cleaning the burrs and grease from at least 19 mm (0.75 in) around the A/C line by using the cleaning pad from A/C Line Repair Kit (J 41425). The A/C line requires preparation with LOK prep sealant while the sealing compound (J 41425-3) needs to be applied as one drop at each line end. After fitting the appropriate component mount the line loop ends and rotate it until an even distribution of sealing compound forms. First position the connector ends properly before inserting the tool (J 41425-1) which covers both the connectors and tubes. Adjust the forcing screw of the tool by using a 1/8 breaker bar until the connector collars reach the center shoulder of the LOK fitting. Following this alignment, remove the tool but confirm the proper installation of the fitting. New lines should be obtained when sectioning the A/C lines before the cutting process begins. Mark and cut the lines while cleaning them afterward to repeat the sealing and fitting process. To conclude the procedure first lower the vehicle then check for coolant needs before sending the system for leak testing and recharging.
