2004 Mercury Sable A/C Hose Parts Q&A

• Q: How to service the A/C Hose from the condenser to the evaporator on 2004 Mercury Sable?

  A: The service procedure for the condenser to evaporator line demands a specific use of Refrigerant Compressor Oil F73Z-19577-AA (Motorcraft YN-9-A) to lubricate R-134a refrigerant system O-ring seals but excludes its usage as an A/C compressor lubricant. Users should apply PAG Refrigerant Compressor Oil F7AZ-19D589-DA (Motorcraft YN-12-C) with equivalent properties matching Ford WSH-M1C231-B to perform compressor lubrication. New suction accumulators must be installed when repairing the air conditioning system only when the system shows contamination from failed A/C compressor problems or suction accumulator damage occurs. Removal of the suction accumulator becomes necessary for vehicles running the 3.0L (2V) engine design. Before working on the 3.0L (4V) engine systems first remove all refrigerant and then remove and discard the suction accumulator O-ring seals together with the compressor manifold and tube fitting. Use the necessary tools to disconnect coolant hoses from the degas bottle while removing bolts so that the lower radiator air deflector can be extracted through either five or seven screw removal dependent on equipment type. The condenser to evaporator line needs removal at the condenser by discarding its O-ring seal. 3.0L (4V) vehicles require removal of the bolt and fuel line bracket and fuel line disconnection and a nut and bracket screw removal from the suction accumulator. All vehicles need their condenser to evaporator line spring lock coupling at the evaporator core inlet to be disconnected while removing the O-ring seals. The 3.0L (4V) vehicle owner needs to move the condenser to evaporator line up around the fuel line before fuel line removal. Install new O-ring seals which received mineral oil lubrication during both engine type installations by following the removal procedure in reverse order. The refrigerant system of 3.0L (4V) engines requires a correct amount of freshly cleaned PAG oil for lubrication. Next technicians must conduct an evacuation and leak check before charging the A/C system.
