• Q: How to Service the A/C Accumulator in the HVAC System on 2008 Lincoln Town Car?

  A: The first step for servicing the suction accumulator in the HVAC system includes placing the vehicle in NEUTRAL as well as securing it on a hoist. The service process starts by extracting refrigerant from the system before disconnecting the outlet fitting of the suction accumulator followed by seal removal. The second step requires removal of the suction accumulator inlet fitting by discarding the existing O-ring seals. Unplug the A/C cycling switch electrical connector before removing the three bolts from suction accumulator while tightening these bolts to 15 Nm (11 lb-ft) during reinstallation. To install the suction accumulator run backward from the removal steps while adding fresh O-ring seals and performing the correct PAG oil lubrication of the refrigeration system. The refrigerant system receives three finishing operations: evacuation followed by testing for leaks followed by charging. The suction accumulator needs replacement if you find physical evidence indicating refrigerant-based A/C compressor failure combined with shell damage, physical shell damage, or moisture contamination that occurred due to loss and atmospheric pressure equalization lasting more than one hour. Installation of a new suction accumulator should be avoided when positive pressures from refrigerant remain prior to repairs.
