2005 Lincoln Town Car A/C Accumulator Parts Questions & Experts Answers

• Q: How to Service the A/C Accumulator in the HVAC System on 2005 Lincoln Town Car?

  A: Begin the service operation on suction accumulators in HVAC systems by first recovering refrigerant. Release the spring lock couplings while removing the O-ring seals through discarding them. The next step involves raising the vehicle after disconnecting the low charge protection switch electric connector. Begin the service by removing the bolts keeping the suction accumulator in place before extracting it from the system. Reinstall the suction accumulator after following the removal steps backward while using new O-ring seals that received oil treatment with mineral oil. The refrigerant system requires clean PAG refrigerant compressor oil at its correct amount with F7AZ-19D589-DA (Motorcraft YN-12-C) or equivalent oil that adheres to Ford specification WSH-M1C231-B. The refrigerant system needs evacuation followed by leakage testing then recharging of refrigerant. The refrigerant compressor oil F73Z-19577-AA (Motorcraft YN-9-A) serves solely for lubricating R-134a refrigerant system O-rings yet must never substitute R-134a refrigerant systems as an A/C compressor lubricant. The replacement of a suction accumulator becomes necessary when direct signs appear showing that its contamination stems from failed A/C compressor equipment and suction accumulator damage.
