By controlling liquid refrigerant delivery, it helps maintain proper system balance in R134A air conditioning circuits. This part is a direct-fit style replacement for front applications on 2015-2025 Ford Transit-150, Transit-250, Transit-350, Transit-350 HD, and 2022-2024 Ford E-Transit, plus 2015-2020 Ford Transit and Transit Custom, and 2018 Ford Transit Connect rear service.\u003c\/p\u003e\u003cp\u003eThis part cross-references UAC EX10497C for the same application. Four Seasons 39550 is also referenced by OE-style numbers used in the same Ford Transit HVAC platform, making it a practical choice when replacing a worn or restricted expansion valve.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Fix\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eWarm air from the vents caused by incorrect refrigerant metering\u003c\/li\u003e\n\u003cli\u003eUneven cabin cooling in Ford Transit front HVAC systems\u003c\/li\u003e\n\u003cli\u003eEvaporator performance issues related to a restricted or sticking valve\u003c\/li\u003e\n\u003cli\u003ePressure imbalance in an R134A air conditioning circuit\u003c\/li\u003e\n\u003cli\u003eService complaints tied to poor refrigerant flow control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the vehicle’s refrigerant type, port style, and mounting layout before installation. This valve uses female sealing-washer connections and is not threaded, so line alignment and sealing surface condition matter during service.
