  Q: How Does the A/C Accumulator Prevent Malfunction and Compressor Damage on Dodge Sprinter 3500?

  A:

  Be sure to adjust the refrigerant oil level in the A/C system, as doing so can prevent the A/C system from failing and your compressor from being damaged. An A/C accumulator needs to be put in if the A/C compressor has an internal issue to prevent more damage. When only the rear A/C accumulator is replaced, you should add 30 milliliters (1 fluid ounce) of recommended refrigerant oil. Be sure to put in new O-ring seals if you remove the A/C accumulator to stop leaks from happening. To begin, uncover any ports on the line fittings and accumulator with your pliers and remove the tape or plugs you see. Clear off any oil from new O-ring seals and then use the appropriate seals for the R-134a system when installing them on the line fittings. Attach the rear A/C accumulator (3) to the end of the rear condenser outlet (1) and to the rear liquid tube (7) and temporarily put on the retaining bolts. Lay the rear A/C accumulator on the rear A/C Condenser (4) and fasten both screws (5). Apply a torque force of 6 Nm (53 in. lbs.) to the bolts joining the rear A/C liquid line and rear condenser outlet line. After the rear A/C pressure transducer (2) is taken out, install it in place and tighten to 10 Nm (88 in. lbs.) and then connect the wire harness connector (6) to the transducer. Place the rear condenser cover on the unit and fit it using retaining screws tightened to 2 Nm (17 in. lbs.). Reattach the negative Battery Cable, remove all the rear refrigerant and if you're putting in a new rear A/C accumulator, add 30 milliliters (1 fluid ounce) of the proper refrigerant oil. The last step is to charge the back refrigerant system.

  Q: How to Service and Repair an A/C Accumulator in the Rear Receiver/Drier System on Dodge Sprinter 3500?

  A:

  To work on the rear A/C accumulator, start with removing the negative Battery Cable, next unscrew the Air Filter on the rear A/C evaporator and finally vacuum the refrigerant from the rear evaporator. After that, take out the cover from the rear A/C condenser housing, unhook the rear refrigerant reservoir from the rear A/C accumulator and toss away the O-ring seal. Take off the liquid line from the rear A/C accumulator and throw away its O-ring. Take out the bolt and retaining bracket joining the rear A/C accumulator to the rear A/C condenser housing and remove the A/C accumulator, then cover both the liquid line fitting and the reservoir and A/C accumulator open ports with plugs or tape. Before fitting the new rear A/C accumulator, drain the refrigerant oil from the old one, record the oil's amount and add an equal quantity of the recommended oil to the new replacement, placing it with the flow arrow pointed in the right direction. Fasten the new rear A/C accumulator against the rear A/C condenser housing, install the holding bracket and torque it to 25 N.m (18 ft. lbs.). Take off the tape or plugs from the liquid line, reservoir and A/C accumulator ports, smear clean oil on a new O-ring seal and fit it over the rear liquid line fitting with the O-ring seal for the system. Screw the rear liquid line into the rear A/C accumulator and tighten it to 35 N.m (26 ft. lbs.). Add refrigerant oil to a second O-ring seal, put it onto the A/C accumulator outlet fitting, then connect the refrigerant reservoir to the rear A/C accumulator, tightening the nut down to 35 N.m (26 ft. lbs.). After replacing the negative battery cable, release the rear refrigerant into the atmosphere, fill the empty rear system with refrigerant, place the air filter at the rear and finish up by attaching the cover to the rear A/C condenser housing.
