How to Service and Repair the A/C Hose on 3.7L/4.7L/5.7L Engines on 2007 Dodge Ram 2500?

Make sure you set the refrigerant oil properly before servicing and repairing the liquid line on 3.7L/4.7L/5.7L engines, so the A/C compressor does not get damaged. When swapping multiple A/C parts, make sure you use the Refrigerant Oil Capacities chart for the correct oil dosage. Whenever you work with a refrigerant line, always change the O-ring seals and gaskets to keep leaks from occurring. Homeowners service their A/C liquid lines in two distinct parts. Lay the front section in the engine compartment, remove any old seals or plugs, brush refrigerant oil on the new O-ring seals and insert them into the front liquid line spring-lock coupler using the right O-ring seals for the R-134a refrigerant. Attach the front section to the rear section using the liquid line, fit the secondary retaining clip, engage the line into the body retaining clips, place a new O-ring and gasket onto the front liquid line, attach the fitting to the A/C condenser outlet, fasten it with a nut that you've tightened to 23 Nm (17 ft. lbs.). First, cover the condenser outlet with the plastic piece, then mount the air filter housing bracket and the air filter housing, reconnect the negative battery cable, next evacuate the system, add or remove refrigerant oil as needed and lastly charge the refrigerant system. For the back part, set it in the engine compartment, clean off any tape or plugs, grease the O-ring seals and clip them onto the rear liquid line spring-lock coupler fitting. Connect the end of the rear section to the evaporator tube, fit the secondary clip at the rear, push the line into the body retaining clip, add seals to the front spring-lock coupler fitting, link the back section to the front section of the liquid line, fix the secondary clip, attach the air filter housing mounting bracket and air filter housing, reattach the negative battery cable, evacuate the refrigerant system, add the proper oil and charge the refrigerant system.
