How to service the rear auxiliary evaporator outlet and inlet A/C hose on 2004 Lincoln Aviator?

The first step for servicing the rear auxiliary evaporator outlet and inlet line includes using a hoist with the NEUTRAL gear selection position and following the component removal sequence. The service technician should remove and recover the refrigerant before taking off the spare tire. The service process requires you to follow the provided sequence for removing components. The only acceptable use of F73Z-19577-AA (Motorcraft YN-9-A) Refrigerant Compressor Oil exists for R-134a refrigerant system O-ring seals and not as A/C compressor lubricant. Users should operate the A/C compressor with PAG Refrigerant Compressor Oil F7AZ-19D589-DA (Motorcraft YN-12-C) or a similar product that fulfills Ford specification WSH-M1C231-B. The replacement of the air conditioning receiver/drier should only be done when evidence shows failure during the A/C compressor operation or extensive receiver/drier damage. New O-ring seals that receive clean mineral oil must become part of disconnected A/C fittings before reinstallation. The installation completion requires following the reversal of your removal steps while using proper PAG oil to lubricate your refrigerant system before evacuation and leak testing and final refrigerant charging process.
