• Q: How to Service and Repair an A/C Expansion Valve on 2006 Dodge Charger?

  A: Before working on the A/C expansion valve, first remove all the refrigerant and take out the negative battery cable. Release the bolt that joins the refrigerant line bracket to the left front shock tower before removing the left side engine mounting nut and second refrigerant line tapping nut. Unplug the wire harness from the A/C pressure transducer, then disconnect both the A/C suction and liquid lines from the expansion valve and put both out of the way. Remove the dual plane seal from the suction and liquid line fittings and seal the holes with either plugs or tape. Unscrew the two bolts attaching the A/C expansion valve to the tapping block, then take out the valve plus the foam seal and throw out the dual plane seal from the fittings on the evaporator tube, also covering the openings. For installation, remove any tape or plugs from the evaporator tube fittings and expansion valve ports, add light clean oil to the dual plane seal, put it onto the fittings and make certain to properly use the seal and refrigerant oil called for in the instructions. Connect the A/C expansion valve to the evaporator tube tapping block using two bolts screwed to 11 N.m and then you can remove any covering on the suction- and liquid-line fittings. Place a new dual plane seal on the fitting covers and install them, finally connecting the suction and liquid lines to the valve. Attach the tapping block to the expansion valve with the nut, tightening them to 23 N.m. After that, set the bolt connecting the refrigerant line bracket to the shock tower to 11 N.m. Link the wire to the A/C pressure transducer, place the negative cable back on the battery, evacuate the refrigerant system and finally charge it.
