  Q: How to Remove an A/C Accumulator on Dodge Ram 2500?

  A:

  The first step is to separate the negative Battery Cable from the A/C system and only then should you collect the refrigerant from the A/C system. After that, remove the air filter housing cover to get to the A/C accumulator (9). Using a screwdriver, remove the secondary retaining clip (11) from the spring-lock coupler (1) at the A/C suction line and accumulator outlet connection. Make sure to use a correct A/C line disconnect tool (Special Tool Kit 7193 or its equal) to separate the A/C suction line from the accumulator and then remove and toss the O-ring seals. Should your vehicle be equipped, take out the push-pin type retainer from the bracket on the side of the A/C accumulator and put the engine wire harness aside. Loose the bolts (8) that keep the A/C accumulator attached to the bracket (7). Take out the second clip (4) from the spring held in the spring-lock coupler (6) which keeps the accumulator inlet tube (3) fitted to the evaporator outlet tube (5). Again, with the disconnect tool designed for A/C lines, separate the accumulator inlet tube from the evaporator outlet tube and throw out the O-ring seals. Then, fill or block off the opened refrigerant system at each connection and, when replacing a new A/C accumulator, remove the mounting bolts and plastic wire harness bracket if your A/C has one.

  Q: How Can Proper Installation of the A/C Accumulator Prevent System Malfunction and Compressor Damage on Dodge Ram 2500?

  A:

  Inside the A/C accumulator, adjust the refrigerant oil level as low as it will go to prevent any problems with the system and protect the compressor from damage. If the A/C Compressor fails inside the system, the A/C accumulator should be replaced because more damage might happen. Always use the Refrigerant Oil Capacities chart when replacing several AC system components to figure out how much oil to add. Add 60 milliliters (2 fluid ounces) of oil exactly as described in the recommendations. Whenever you remove a refrigerant line from a system, remember to replace both paper and rubber O-rings on the ends. To start, put the plastic bracket for the wire harness and the accumulator mounting bolts onto the accumulator only loosely. Assemble the accumulator onto the dash panel on the engine side, do not tighten the bolts yet. Pull out all the tape and cap-off plugs from the refrigerant system connections. Use clean refrigerant oil to grease new O-ring rubber seals and place them onto their fittings with only the recommended seals for a R-134a unit. Couple the spring-lock portion of the accumulator inlet tube to the evaporator outlet tube and put on the secondary retaining clip. Aim for 6.8 Nm (60 in. lbs.) when tightening the bolts that hold the accumulator. If your wiring allows, fit the engine wire harness retaining clip into the plastic wire harness bracket found on the A/C accumulator. Attach the A/C suction line to the accumulator outlet tube and put on the secondary retaining clip. Put in the air filter housing cover and reattach the battery negative cable. After cooling down the system, empty its refrigerant and then, if the A/C accumulator was changed, add 2 fluid ounces or 60 milliliters of recommended refrigerant oil.
