• Description:

  Genuine Ford OEM A/C expansion valve part number HL3Z-19849-D used across multiple Ford platforms running R-1234yf refrigerant. This valve fits 15-22 F-150 trucks without the 3.0L diesel option, plus 17-22 F-250, F-350, F-450, and F-550 Super Duty trucks equipped with the 6.2L gasoline V8, 6.7L Power Stroke diesel, or 7.3L Godzilla gasoline V8, when ordered with manual temperature control. This part supersedes earlier service numbers FL3Z-19849-A and Motorcraft YF-789. The expansion valve meters refrigerant flow into the evaporator core, dropping refrigerant pressure and allowing evaporative cooling to chill cabin air. Internal calibrated orifices and a temperature sensing bulb work together to modulate flow against varying engine cooling demands. When the original valve sticks, leaks, or contaminates after a compressor failure, replacement with this OEM unit restores factory cooling performance. Ford service procedures call for new O-ring seals with every opening of the refrigerant circuit, full evacuation under vacuum, and recharge to the specification listed on the underhood label. Cross-platform fitment between the F-150 and Super Duty platforms is a known characteristic of this part number, so verify your truck's manual temperature control configuration before ordering. Ships in original packaging with Ford parts warranty.
