How to Service and Repair the A/C Hose on Lincoln Navigator?

The first requirement to repair or service the HVAC hose/line involves executing the Refrigerant Discharging and Recovery Procedure. The A/C evaporator core spring lock coupling must first be disconnected from the condenser to evaporator line then the A/C condenser core lower line needs its nut removed. The HVAC service requires you to disconnect the A/C condenser core lower line followed by nut removal from the tube bracket and suction accumulator/drier bracket clamp bolt removal. You must remove the evaporator to condenser tube as the final step. The installation process leads in the opposite direction of the removal sequence while applying PAG Compressor Oil or equivalent WSH-M1C231-B specified by Ford. Finish by executing the Evacuation and Charging Procedure.

How to Service and Repair the A/C Hose in the Compressor Manifold and Tube Assembly on Lincoln MKZ?

Refrigerant recovery should precede hoisting the vehicle to NEUTRAL position. Follow this procedure to remove the lower engine splash shield when present then detach the compressor manifold from the A/C compressor through bolt removal before discarding gasket seals with a new installation torque to 15 Nm (11 lb-ft). The service requires removing the two coolant reservoir hose retainers from the assembly and unbolted the washer reservoir filler neck, then reinstalling it with 6 Nm (53 lb-in). After removing the fitting nut on the compressor manifold and tube suction fitting the installation can begin with a new gasket seal. The new installation should be tightened to 15 Nm (11 lb-ft). The procedure also includes disconnecting and removing the condenser inlet fitting nut with the discard of the gasket seal followed by a new installation torque to 15 Nm (11 lb-ft). The compressor manifold and tube must be rotated counterclockwise for 3.5L vehicles to move vertically into position between the exhaust manifold shield and alternator before uninstallation. Vehicle owners operating 3.0L models should proceed with caution to prevent striking the A/C lines against any obstruction. The installation process ends when you complete the reverse procedure through the removal process while also adding new gasket seals followed by lubricating the refrigerant system using the proper amount of clean PAG oil before conducting an evacuation, leak test and charge on the refrigerant system.

Also apply new O-ring seals that received pre-lubrication in the same oil. The refrigerant system requires evacuating then leak testing before charging its components. The suction accumulator needs replacement when physical contamination reveals from a malfunctioning A/C compressor or succeptor damage occurs.

Q: How to Service and Repair the A/C Hose in the Compressor Manifold and Tube Assembly on Lincoln MKZ?
A: Refrigerant recovery should precede hoisting the vehicle to NEUTRAL position. Follow this procedure to remove the lower engine splash shield when present then detach the compressor manifold from the A/C compressor through bolt removal before discarding gasket seals with a new installation torque to 15 Nm (11 lb-ft). The service requires removing the two coolant reservoir hose retainers from the assembly and unbolted the washer reservoir filler neck, then reinstalling it with 6 Nm (53 lb-in). After removing the fitting nut on the compressor manifold and tube suction fitting the installation can begin with a new gasket seal. The new installation should be tightened to 15 Nm (11 lb-ft). The procedure also includes disconnecting and removing the condenser inlet fitting nut with the discard of the gasket seal followed by a new installation torque to 15 Nm (11 lb-ft). The compressor manifold and tube must be rotated counterclockwise for 3.5L vehicles to move vertically into position between the exhaust manifold shield and alternator before uninstallation. Vehicle owners operating 3.0L models should proceed with caution to prevent striking the A/C lines against any obstruction. The installation process ends when you complete the reverse procedure through the removal process while also adding new gasket seals followed by lubricating the refrigerant system using the proper amount of clean PAG oil before conducting an evacuation, leak test and charge on the refrigerant system.

Q: How to Service and Repair the A/C Hose from the Evaporator to Compressor Suction Line on Lincoln Town Car?
A: The service process for the evaporator to compressor suction line starts with proper recovery of refrigerant. Eject the suction line by disconnecting its spring lock coupling that starts with the suction accumulator and concludes at the compressor manifold and tube assembly. Installation of the evaporator entails an opposite removal method after properly applying clean PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or an equivalent that fulfills Ford specification WSH-M1C231-B. Also apply new O-ring seals that received pre-lubrication in the same oil. The refrigerant system requires evacuating then leak testing before charging its components. The suction accumulator needs replacement when physical contamination reveals from a malfunctioning A/C compressor or succeptor damage occurs.
