How to Service and Repair the A/C Expansion Valve for the Auxiliary Climate Control on Ford Excursion?

You must accomplish refrigerant recovery and discharging before beginning service and repair tasks on the expansion valve of the auxiliary climate control system. Move on to the second step by removing the right-hand rear quarter trim panel access panel along with its associated jack unit. Remove the A/C lines from the A/C evaporator expansion valve before detaching the expansion valve from the core of the evaporator. The installation requires reversing the prior removal steps while using PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or an equivalent product that satisfies Ford specification WSH-M1C231-B for lubricating the O-ring seals. Conclude the process by performing evacuation then leakage testing and system charging.

How to Service and Repair the A/C Expansion Valve on Ford Expedition?

Start the service and repair process of the A/C expansion valve by recovering all refrigerant first. The powertrain control module together with the bracket needs to be removed first. The fitting bolt of the A/C expansion valve needs to be removed followed by O-ring seal disposal before torquing the new bolt up to 8 Nm (71 lb-in). After removing the two bolts from the A/C expansion valve, proceed by discarding its O-ring seals before installing new seals, which should be tightened to 8 Nm (71 lb-in). The repair process involves reversing the removal steps and replacing the O-ring seals along with PAG oil lubrication of the refrigerant system with sufficient clean PAG oil. End the process by evacuating and leak-testing and then charging the refrigerant system.

How to Service and Repair the A/C Expansion Valve on Ford Thunderbird?

The first step for servicing the A/C expansion valve includes removing the evaporator core. First, disconnect the outlet fitting of the evaporator by removing the O-ring seal to save for replacement purposes. Install the new fitting while torquing it to 24 Nm (18 lb-ft) when completed. You should disconnect the evaporator inlet fitting before discarding its O-ring seal, using 24 Nm (18 lb-ft) torque when tightening the new fitting. The installation of new O-ring seals requires lubrication with clean mineral oil according to the manufacturer specifications. The use of refrigerant compressor oil (mineral oil) for R-134a refrigerant system O-ring sealing remains appropriate, but its addition to the R-134a refrigerant system for compressor lubrication should be done with PAG refrigerant compressor oil. A receiver/drier replacement becomes necessary only in cases when a failed A/C compressor or damaged receiver/drier shows signs of contamination.
