How to replace the Front A/C Hose on Chevrolet Express 3500?

You need to start by disconnecting the negative Battery Cable and recovering refrigerant from the system before tube evaporator replacement. First disconnect the evaporator tube from both the evaporator and its mounted o-ring seal before removing the radiator grille and the connecting evaporator tube from the condenser. Before removing the evaporator tube from the auxiliary a/c evaporator underbody front tube assembly the vehicle should be raised on safety stands. Begin installation by using a new 525 viscosity refrigerant oil-coated o-ring seal which you should place before attaching the evaporator tube to the condenser and tightening it to 19 n.m (14 lb ft). The radiator grille goes back into place followed by another new o-ring seal applying 525 viscosity refrigerant oil before connecting the evaporator tube to the evaporator while tightening it to 19 n.m (14 lb ft). Connection of the evaporator tube requires the auxiliary a/c evaporator underbody front tube assembly when present. Install it and tighten securely to 19 n.m (14 lb ft). After removing safety stands the vehicle should be lowered while the negative Battery Cable should be reconnecting. The refrigerant should be recharged to the system before leak inspections are performed.

How to service the rear A/C Hose using the A/C Line Repair Kit (J 41425) on Chevrolet Express 3500?

Service of rear heater or A/C lines requires the use of the A/C Line Repair Kit (J 41425) to fix rub-through and collision damage and prevent leakage. Always maintain a proper minimum distance in straight line sections on each side of the spliced area during repair operations. Cut the broken part with a tubing cutter following removal of the damaged section and trim the repair line to equal the original length. Start by lifting the vehicle and identifying the damaged area for replacement line installation. Then obtain a section of new tube. The damaged section requires cutting by a tubing cutter before removal while the replacement line receives this same length modification. Clean line ends with the cleaning pad from the J 41425 A/C Line Repair Kit before applying LOK prep sealant. Put a single drop of sealing compound (J 41425-3) on each line end before inserting LOK fittings while rotating the fittings to spread the compound. Use the tool body J 41425-1 with the right LOK fitting jaws to position over the LOK connectors while maintaining proper alignment. Use a 3/8" breaker bar to hold the tool body while tightening the forcing screw until it reaches the bedding position on the fitting. Verify the LOK fitting installation after loosening the screw and removing the tool body. When performing line sectioning repairs keep replacement lines at the same length while staggering splices if rebonding multiple lines. Finish vehicle repairs by lowering the vehicle and refilling drained fluids before you evacuate then recharge A/C refrigerant systems as part of your line repair process.
