  Q: How to Service and Repair an A/C Accumulator in the Rear Refrigerant System on Dodge Sprinter 2500?

  A:

  You should unhook the negative Battery Cable, then take out the Air Filter in the back A/C evaporator housing. Pull the refrigerant out of the back refrigerant system and take the rear A/C condenser cover off. Separate the rear liquid line from the rear A/C accumulator and remove the O-ring there. Then break the link between the rear A/C accumulator and the rear receiver/drier and toss the O-ring seal there too. Take out the bolt and retaining bracket joining the rear A/C accumulator to the rear A/C condenser housing and pull out the accumulator. Put plugs into the open rear liquid line fitting and close the receiver/drier and accumulator ports with tape. When you put in the new rear A/C accumulator, add the same type and amount of refrigerant oil using the drained oil to see how much you should add. Change the rear receiver/drier, set up the rear A/C accumulator near the rear A/C condenser housing and bolt it to the condenser, tightening the bolt to no more than 25 N.m (18 ft. lbs.). Take the tape or plugs off the rear liquid line fitting and off both the receiver/drier and the accumulator ports on the fuse box. Place the new rear O-ring seal into the receiver/drier, add a small amount of clean refrigerant oil to it and make sure it is the proper R-134a seal. First, put the connecting pipe between the receiver/drier and rear A/C accumulator; then tighten the nut until you reach 35 N.m (26 ft. lbs.). Use clean refrigerant oil to lubricate the next O-ring, put it on the connection fitting and loop the rear liquid line onto the rear A/C accumulator, securing it with 35 N.m (26 ft. lbs.) of torque. After reconnecting the negative battery cable, evacuate the back refrigerant system, add freon, fit the rear air filter and then put the cover over the rear A/C condenser housing.

  Q: How to Remove the A/C Accumulator on Dodge Sprinter 2500?

  A:

  Before pulling the A/C accumulator out, first take out and separate the negative Battery Cable and then collect the refrigerant. After that, detach the Grille and the condenser fan assembly installed at the front of the A/C Condenser. Free the bolt at the right end of the A/C condenser that secures the A/C accumulator and unlink the accumulator mounting bracket from the A/C condenser. Unplug the A/C accumulator from the A/C condenser, then take off and toss the O-ring seals. In case you must, disconnect the bracket holding the A/C accumulator to the heater housing. After that, cover the A/C accumulator and condenser ports with plugs or tape.
