How to Service and Repair the A/C Hose for 3.7L, 4.7L, and 5.7L Engines on 2008 Dodge Ram 3500?

For all 3.7L, 4.7L and 5.7L engines, make sure to adjust the refrigerant oil level so that the A/C compressor will not be damaged. You should use the Refrigerant Oil Capacities chart to find how much oil is needed when replacing a number of your A/C components. Each time you open a refrigerant line, change the O-ring seals and gaskets to ensure no leaks happen. This line is serviced in two specific sections. Fit the front section into the engine compartment, take off any tape or plugs from its ends, add a touch of clean refrigerant oil to the new O-ring seals and use the fitting's spring-lock for the R-134a refrigerant to secure it in place. Link the from liquid line to the rear liquid line, add the secondary retaining clip, fit the lines into the body clips, apply new lubricant to the front O-ring and gasket, attach the front liquid line to the A/C condenser outlet port and secure everything in place with a tightened nut at 23 Nm (17 ft. lbs.). Fit the plastic cover over the condenser outlet stud, hook up the air filter housing mounting bracket and put on the air filter housing. After that, connect the negative battery cable. Pull out the refrigerant, set the refrigerant oil at the correct level and insert refrigerant into the system. For the back section, set it behind the engine, take off any protective tape or stoppers, coat the seals with lubricant and fit the grooves onto the rear liquid line spring-lock coupler fitting. Bring the rear section and the evaporator tube together, attach the secondary clip, join the line to the body retaining clip, grease the new O-ring seals on the front liquid line coupler fitting and install them, attach the rear section to the front section of the liquid line, add the secondary clip, fit the bracket and the air filter housing, reattach the negative battery cable, evacuate the refrigerant system, level the refrigerant oil and charge the system.
