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

• Q: How to Service and Repair the A/C Condenser Core on 2005 Lincoln Town Car?

  A: The HVAC condenser core needs lubrication by using refrigerant compressor oil F73Z-19577-AA (Motorcraft YN-9-A) exclusively for R-134a refrigerant system O-ring seals. This oil must not serve as an A/C compressor lubricant; instead utilize PAG refrigerant compressor oil F7AZ-19D589-DA (Motorcraft YN-12-C) or an equivalent certified for A/C compressor lubrication according to Ford specification WSH-M1C231-B. Conduct a leak test on the A/C condenser core before removing it when leakage is suspected. Replacement of the new suction accumulator becomes necessary only when one discovers accumulation of contaminants caused by failed A/C compressors or damaged suction accumulator components. The first task is to recover the refrigerant followed by removal of the battery then pin-type retainers and radiator upper sight shield. Remove fittings from the condenser unit while throwing away O-ring seals. First remove radiator bracket bolts before finishing the condenser bracket nut uninstallation. Performs the extraction of the A/C condenser core by tilting the radiator. The installation process starts with step-by-step reverse of the removal process while incorporating new O-ring seals treated with mineral oil and completing the system lubrication with PAG oil. Finish the process by evacuating the refrigerant system and performing pressure and temperature checks followed by refrigerant pressurization.
