  Q: How to service and repair the A/C Accumulator on Dodge Ram 2500 Van?

  A:

  To start working on the A/C accumulator, unhook and separate the cable from the battery negative. Once done, recover all the refrigerant from the system. Remove the screw attaching the A/C accumulator to the bracket and the screw on the A/C accumulator side of the liquid line block fitting, then disconnect the fitting and apply plugs or tape over all exposed connector ends. After that, take out the screw securing the A/C accumulator outlet to the suction line jumper block fitting and detach the A/C accumulator outlet from the suction line jumper block fitting, remembering once more to install plugs in or tape over all open refrigerant line fittings only after separating the A/C accumulator from the engine compartment. Replace the tape or plug from the suction line jumper block fitting and A/C accumulator outlet, line up the A/C accumulator outlet with the suction line jumper block fitting, attach them with a screw and tighten it to 13.5 Nm (120 in. lbs.). Next, open the tape or remove the plugs at the liquid line block fitting and the A/C accumulator inlet, fit the liquid line block to the A/C accumulator inlet and secure it with a screw, keeping 13.5 Nm (120 in. lbs.) tightness. Put the negative battery cable back in place, remove the refrigerant from the system and then charge it. If you replace the A/C accumulator, add 30 milliliters (1 fluid ounce) of the refrigerant oil specified by the car's manufacturer to the refrigerant system.
