Product Details

Four Seasons 39120 is an A/C expansion valve designed to regulate refrigerant flow into the evaporator on compatible Kia Sportage HVAC systems. This block-type valve uses female FIO insert O-ring inlet and outlet connections, with No. 10 suction ports and No. 6 liquid inlet sizing, making it a precise service part for R134A-equipped vehicles. The Four Seasons Expansion Valve line focuses on direct-fit HVAC flow control components, and this 39120 valve follows that approach for repair work where accurate refrigerant metering is required.

Installation Notes and Tips

Verify the vehicle uses an R134A system and confirm the valve style, port sizes, and mounting layout before installation. Replace sealing O-rings as needed during service, and inspect the A/C system for contamination or debris that could affect the new valve. Proper evacuation, leak checking, and recharge procedures are important after replacement. Fits 1998-2002 Kia Sportage, expansion valve.
