  Q: How to Service and Repair an A/C Accumulator on Dodge Durango?

  A:

  To start the service on the A/C accumulator, first disconnect and isolate the negative battery cable, then take out the refrigerant from the refrigerant system. Open the four refrigerant lines at the front and rear block fittings, disengage the block fittings from the A/C accumulator and ensure you install a plug or tape over all the opened lines. After that, remove the single screw holding the A/C accumulator mounting bracket to the front fender wheelhouse front extension, then take out the A/C accumulator from the front of the engine compartment. Secure the bracket and the A/C accumulator to the front extension above the front wheelhouse of the fender only with a temporary mounting screw. Unplug the inlet fitting at the front liquid line block and the inlet of the A/C accumulator and then attach the front liquid line block fitting to the A/C accumulator inlet, screwing it on until the torque dial reads 13.5 Nm (120 in. lbs.). Repeat the previous step on the rear liquid line block fitting, as well as the A/C accumulator outlet, all four to 13.5 Nm (120 in. lbs.). Screw the A/C accumulator bracket firmly until it registers 6.8 Nm of torque (60 in. lbs.). Afterward, plug the battery negative cable back in, empty the system of refrigerant and recharge it. Upon replacing the A/C accumulator, add 1 fluid ounce (30 milliliters) of the proper refrigerant oil specified by the vehicle's maker for the compressor.

  Q: How to Properly Maintain an A/C Accumulator for Optimal System Performance on Dodge Durango?

  A:

  It is necessary to monitor and regulate the refrigerant oil level when working on an A/C refrigerant system to stop the system from working incorrectly and damaging the compressor. An A/C accumulator is required if there was a compression-side failure not fixable by the recharge service, to prevent additional problems. Should you be replacing several parts of your A/C system, use the Refrigerant Oil Capacities chart to see how much oil to add. For an A/C accumulator replacement, only, add 30 milliliters (1 fluid ounce) of the bicycle's recommended refrigerant oil to the A/C compressor. Every time you open a refrigerant line, be sure to change the O-rings and gaskets to reduce the risk of leaks. First, put the accumulator and bracket into the engine area, then insert the right front frame rail bolt and tighten it to 9 Nm (80 in. lbs.). Following that, put the front and rear liquid lines into the accumulator. Remove all of the refrigerant from the system and if a new A/C accumulator has been used, add the right amount of refrigerant oil. After all the checks, make sure to charge the refrigerant to the manufacturer's recommended level.
