How to service and repair A/C Hose pipes using the A/C Line Repair Kit (J 41425) on 2003 Chevrolet Suburban 1500?

The A/C Line Repair Kit (J 41425) serves to address rub-through, collision damage and leakage in the system for heater and A/C pipe service and repair operations. You need to maintain correct minimum length in the straight line portions on both sides during the process of sectioning the rear A/C or heater lines. When fixing straight heater or A/C lines you need to recover or drain the cooling fluids respectively. Begin by elevating the vehicle before you find the damaged area and obtain a suitable replacement line. A tubing cutter should trim away the damaged part while the new line needs to reach the same dimensional length. The user must utilize the cleaning pad from the A/C Line Repair Kit (J 41425) to remove burrs and grease while ensuring the ends stay 19 mm (0.75 in) clean. The sealing process begins with LOK prep sealant and requires one drop of sealing compound (J 41425-3) on each end before inserting the line ends into the LOK fitting. Twist the fitting one complete rotation to distribute the sealing compound before placing the appropriate LOK fitting jaws on the tool (J 41425-1) and position it over the LOK connectors to ensure their position in the counter bore. The tool operator should use the provided 3/8 inch breaker bar to hold the LOK fitting tool while turning the forcing screw until the connector collars settle onto the center shoulder. Release the forcing screw before taking out the tool and check that the LOK fittings have been set correctly. Rephrase the procedure for the opposing A/C line end before lowering the vehicle and perform coolant refilling operations followed by the repair procedure for the AC system if necessary. Line sectioning repair procedures require the same steps while implementing multi-line splice stagger and ensuring all replacement lines have equivalent lengths.
