Product Details

The Four Seasons 39265 expansion valve regulates refrigerant flow into the evaporator so the rear air conditioning system can maintain proper cooling performance. Its block-type design, No. 10 suction inlet and outlet sizing, and No. 6 liquid inlet with No. 8 liquid outlet sizing support the factory-style layout used on the listed Volvo XC90 rear system applications. The Four Seasons Expansion Valve line focuses on service replacement parts that match OE-style fitment and system requirements, and this part follows that approach for the XC90 rear HVAC circuit.

This part cross-references UAC EX529474C for the same application.

What It Helps Address

• Rear A/C air that is warm or not cooling evenly
• Refrigerant flow issues at the evaporator inlet
• Erratic cabin temperature control from a restricted valve
• System performance loss after A/C service or component replacement
• Fitment-related replacement needs on Volvo XC90 rear HVAC systems

Installation Notes and Tips

Install the valve in the rear HVAC location specified for the vehicle application and verify all O-ring sealing surfaces are clean before assembly. Replace damaged seals as needed, confirm the system is charged with R134A, and evacuate and leak-check the system after installation. Always match the part to the vehicle’s rear A/C configuration before service.

Quality Assurance

Four Seasons 39265 is listed as meeting or exceeding OEM requirements for the specified applications. It is built as a direct-fit replacement for rear A/C service on the confirmed Volvo XC90 fitments.
