How to service and repair the A/C Expansion Valve for auxiliary climate control on Ford Expedition?

The first step for repairing or servicing the A/C Expansion Valve for auxiliary climate control systems in Expedition and Navigator models involves refrigerant recovery. Start by removing the right-hand quarter trim panel followed by disconnecting the A/C Expansion Valve fitting through the removal of its bolt. The service technician should discard the O-ring seals currently in use at this point. The two A/C Expansion Valve bolts should be removed while also extracting the A/C Expansion Valve before discarding its O-ring seals. The installation process requires executing the reversal of removal steps including new O-ring seal installation and proper addition of clean PAG oil to the refrigerant system. To end the process, you need to evacuate and then perform leak tests followed by system charging.

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

Recovery of refrigerant must happen first before performing maintenance or repairs on the expansion valve that serves the auxiliary climate control. Begin by removing the access panel from the right-hand rear quarter trim panel after which you can remove the jack. Remove the expansion valve from its connection to the evaporator core after detaching the A/C lines from the expansion valve mounted on the evaporator. The installation process should begin by performing the removal steps in reverse order while lubricating O-ring seals with PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or an equivalent that fulfills Ford specification WSH-M1C231-B. The A/C system processing ends with evacuation then leak checks that lead to system charging.

Ford A/C Expansion Valve

If you own Ford and want to keep it in top shape, choosing OEM A/C Expansion Valve is a smart move. They are precisely engineered and follow strict factory standards.

FordPartsDeal.com gives you genuine Ford A/C Expansion Valve at some of the affordable online prices without cutting quality. Every OEM Ford part includes the manufacturer's warranty, easy returns, and super-fast delivery. So why wait? Shop now and get your vehicle back to peak condition.

Ford A/C Expansion Valve controls the flow of refrigerant at a precise amount which maintains constant and efficient cabin temperatures. Ford started with the 1903 start-up by Henry to become a world power by introducing the moving assembly line in 1913, reducing the time to build a car by half and making reliable transportation affordable to every family. Ford offers EcoBoost power with frugality, SYNC voice command so motorists can summon music or directions without using their hands and supports it with Co-Pilot360 assistant, which monitors the lanes and brakes under threat. Ford is now going the all-electric route with vehicles such as the F-150 Lightning, and it is demonstrating the capability of big trucks to rocket off without emitting fog through the tailpipe. Through continuous research, Ford continues to refine its lineup with the aim of ensuring that its trips are simpler, safer, and more fun. A/C Expansion Valve injects liquid refrigerant into the evaporator at the correct pressure that allows it to boil immediately, resulting in absorbing cabin heat rather than bogging the compressor or flooding the lines. A/C Expansion Valve responds to changes of load within a few seconds, opening more under blistering traffic at idle and closing under highway cruises, therefore the system does not lure people to sweat or waste fuel by overcooling them. A/C Expansion Valve also protects costly compressors by avoiding slugging of liquid, which stretches the life of the parts and reduces repair expenses throughout the life of the vehicle. Maintained A/C Expansion Valve ensures that all the pressures are maintained regardless of the season outside.
