Detailed Description

Four Seasons 39356 is an A/C expansion valve used to regulate refrigerant flow into the evaporator, helping maintain proper system balance in the HVAC circuit. This block-type valve uses female suction and liquid connections with sealing washers, and its aluminum construction supports reliable service in R134A-equipped systems. The Four Seasons Expansion Valve line is focused on OE-style replacement parts for common service applications, and this unit is listed as a direct replacement for select Ford Expedition, Lincoln Navigator, Ford F-150, and Ford F-350 Super Duty vehicles.

This part cross-references UAC EX10370C and EX529492C for the same application. The 39356 part number also appears in interchange listings for multiple OE and aftermarket references, making it a practical match when replacing a failed expansion valve in a Ford Expedition or Lincoln Navigator front HVAC system.

What It Helps Fix

• Inconsistent cabin cooling from improper refrigerant metering
• Warm air from the vents when the A/C system is charged but not regulating correctly
• Evaporator performance issues caused by a sticking or restricted expansion valve
• Pressure imbalance in the A/C circuit
• Front HVAC cooling complaints on compatible Ford and Lincoln vehicles

Installation Notes and Tips

Verify refrigerant type, port style, and mounting-hole layout before installation. This valve uses sealing-washer connections and female fittings, so clean mating surfaces and correct seal placement are important for leak-free service. Confirm the system is properly evacuated and recharged after replacement, and inspect related A/C components such as the evaporator, compressor, and lines if the original valve failed from contamination.

Compatible with 2009-2017 Ford Expedition, front; 2009-2017 Lincoln Navigator, front; 2009-2014 Ford F-150, N/A; and 2010 Ford F-350 Super Duty, N/A. For fitment searches, this part is commonly referenced for 2009-2017 Ford Expedition front A/C repair and 2009-2017 Lincoln Navigator front HVAC service.

Quality Assurance

Four Seasons 39356 is listed as meeting or exceeding OEM requirements for the specified applications. The aluminum construction and OE-style configuration support service replacement on R134A systems using the correct port sizes and sealing-washer design.
