2004 Lincoln Town Car A/C Accumulator Parts Questions & Experts Answers

• Q: How to Service the A/C Accumulator in the HVAC System on 2004 Lincoln Town Car?

  A: The refrigerant service requires initial recovery before servicing a suction accumulator of an HVAC system. Disassemble spring lock couplings before getting rid of the needed O-ring seals. The service requires detachment of the low charge protection switch electrical connector followed by lifting the vehicle. Begin by disassembling the suction accumulator through removing its securing bolts then removing the component. Install the new suction accumulator by doing the reverse of the removal steps while using fresh O-rings that received PAG oil lubrication. The refrigerant system requires proper application of clean PAG oil followed by lubrication. Evacuate the system through the final step followed by leakage testing and then performing the system recharge. The application of F73Z-19577-AA Refrigerant compressor oil must remain limited to R-134a refrigerant system O-ring seals and must not be used for A/C compressor lubrication. However, A/C compressor lubrication demands PAG refrigerant compressor oil F7AZ-19D589-DA or its equivalent which satisfies Ford specification WSH-M1C231-B. A new suction accumulator needs installation exclusively when physical signs point to damaged suction accumulator components or based on failures of the A/C compressor system.
