How to Service the A/C Expansion Valve on Mercury Mariner?

Begin recovery of refrigerant before working on the thermostatic expansion valve (TXV). Disconnect the TXV fitting by rotating its nut and then take off the parts including all gasket seals. Eliminate the two TXV bolts first along with the TXV from the system while getting rid of its O-ring seals. Following uninstall steps, tighten the TXV stud to 6 Nm (53 lb-in) before adding the TXV fitting nut. Put new gasket and O-ring parts in place and finish the process by taking the air out of the system and checking for leaks before adding refrigerant. A new receiver/drier must replace the old unit when physical signs show a broken A/C compressor or receiver/drier damage.
