How to service and repair the A/C Hose from the compressor to the condenser on 2009 Mercury Grand Marquis?

The first step before servicing any part involving the compressor to condenser discharge line involves collecting the refrigerant. First disconnect the condenser inlet fitting by removing its nut while discarding both the O-ring seal and gasket seal and during new fitting installation ensure proper torque of 15 Nm (133 lb-in). After disconnecting the A/C pressure transducer electrical connector remove the compressor discharge fitting nut and detach the fitting according to the direction. Seal replacement should follow using new components and applying 15 Nm (133 lb-in) torque during installation. Protection of the A/C system starts with compressor-to-condenser discharge line removal. Installation of the new line requires following the removal steps in reverse order using new gasket seals and O-ring seals together with the correct amount and clean PAG oil for lubrication. As a final step you need to evacuate the refrigerant system while conducting leak tests before charging the system.
