  Q: How to Remove and Install an A/C Accumulator in a Refrigerant System on Chrysler PT Cruiser?

  A:

  First, unhook the negative battery terminal and let it stand a bit before gathering the refrigerant from the refrigeration system. If you can't get the servo control out with the vehicle at ground level, lower the vehicle to reach the servo and the accumulator inside. Unplug the A/C low pressure switch from the wire harness, unfasten the nuts on the suction and liquid lines to the accumulator tube tapping block and remove the lines by discarding their O-ring seals. For the open fitting on the suction and liquid line and the accumulator tapping block ports, use either plugs or tape. Take out the bolt holding the accumulator bracket to the frame rail, plus the two bolts joining the accumulator tubes to the Evaporator tube tapping block and then separate the tubes. Throw out the old gasket. As before, use tape or plugs to seal the holes in the accumulator tube and evaporator. Take out the assembly of tubes by the evaporator and accumulator from under the hood and stand it on a table. Screw out the bolts from the fittings on the accumulator tubes, free the tubes, cast off the O-ring seals and fit the accumulator tubes with new sealing plugs or cover them with tape. Pull the A/C low pressure switch from the accumulator and throw away the O-ring seal. When replacing the accumulator, put 30 milliliters (1 fluid ounce) of refrigerant oil into the A/C system only with the recommended oil for the compressor. Put in the A/C low pressure switch on the accumulator using a new O-ring seal and tighten it manually. After opening the accumulator tube fittings and ports, remove the tape or plugs, lubricate new rubber O-ring seals using clean refrigerant oil and attach them to the accumulator tube fittings, using only the correct R-134a system O-rings. Hook the accumulator tubes to the accumulator, then fasten the two required bolts to 11 N.m (97 in.lbs.). Put the accumulator and tubes in your vehicle's engine area, take off any passage plugs from the open ports, lubricate a fresh gasket with refrigerant oil and connect the gasket to the evaporator tube tapping block. Connect the accumulator tubes to the evaporator tube tapping block, install the two bolts holding them together and tighten them to a torque of 11 N.m (97 in.lbs.). Put the end that secures the accumulator bracket through the hole, line up the notches and torque to 10 N.m (89 in.lbs.). Pull out the tape from opened suction and liquid line fittings and the accumulator tube tapping block, oil the new O-rings, install them on the suitable line fittings and be sure to use only the appropriate O-rings with the system's R-134a gas. Join the A/C suction and liquid lines to the taps on the accumulator tube block, fit the nuts and tighten them to 5 N.m (44 in.lbs). Connect the wire harness connector to the A/C low pressure switch, if there is a vehicle speed control servo, reinstall it, reattach the negative Battery Cable, get rid of the refrigerant and charge the refrigerant system.

  Q: How to Service and Repair an A/C Accumulator on Chrysler PT Cruiser?

  A:

  Begin the service and repair of an accumulator HVAC by recovering the refrigerant from the refrigerant system. Take out the battery negative cable from the car. If necessary, move the vehicle speed control servo so you can reach the accumulator. Take out the low pressure clutch cycling switch from the accumulator. After that, take out the screws that join the suction and liquid line assembly's refrigerant line fittings to the accumulator connector block and remove those fittings. Eliminate the rubber O-ring from the refrigerant line connectors and seal the ports on the accumulator connector block and the fittings with plugs or with tape. Open the screw securing the accumulator mounting bracket to the right side rail and take out the accumulator from its position in the engine space. For the installation, put the accumulator in the engine compartment and use miniature screwdrivers to tighten the mounting bracket screw to 11.3 Nm (100 in. lbs.). Take away the tape and plugs from where the accumulator connects and at the same time, from all R-134a refrigerant line fittings and then lubricate new rubber O-ring seals with clean refrigerant oil and put them on the R-134a refrigerant line fittings. Attach the refrigerant line fittings to the accumulator connector block ports and tighten the screws using 2.3 Nm (20 in. lbs.) as your guide. Install the low pressure clutch cycling switch onto the accumulator and, if the vehicle needs it, reinstall the speed control servo too. Connect the terminal on the battery's negative cable and pull out the refrigerant system. If you change the accumulator, put 89 milliliters (3 fluid ounces) of the recommended refrigerant oil into the system before charging it. At this time, fill the refrigerant system to its optimum operating level.
