Global Parts 3412032 A/C Expansion Valve

A/C Expansion Valve for Kia Cadenza and Optima

Global Parts 3412032 is an A/C expansion valve/orifice tube designed to regulate refrigerant flow before it enters the evaporator. By slowing refrigerant at this point, the system can use its cooling capacity more effectively. This part is a direct-fit service component for select Kia Cadenza and Kia Optima applications.

Key Features

• OE-style A/C expansion valve for refrigerant metering at the evaporator inlet
• Fits 2019-2020 Kia Cadenza and 2017-2020 Kia Optima
• Supports proper refrigerant pressure drop across the HVAC system
• Global Parts part number 3412032 for service and replacement matching
• This part cross-references Four Seasons 39612 and UAC EX10676C for the same application

How It Works

The expansion valve controls refrigerant delivery into the evaporator so the A/C system can absorb heat efficiently. On Kia Cadenza and Kia Optima models, a worn or restricted valve can affect cooling performance, system balance, and overall HVAC operation. Global Parts 3412032 is built for the listed vehicle applications and matches common replacement references used in A/C service.

Common Problems This Part Can Address

• Weak or inconsistent cabin cooling
• Improper refrigerant flow through the evaporator
• High-side or low-side pressure irregularities during A/C operation
• Reduced cooling output after HVAC service
• Expansion valve restriction from age or contamination

Installation Notes

Fits 2019-2020 Kia Cadenza and 2017-2020 Kia Optima, N/A. Replace the expansion valve during A/C service when the system has been opened, and verify refrigerant charge, seals, and system cleanliness before returning the vehicle to service. Proper evacuation and recharge procedures are important for stable HVAC performance.

Quality Assurance

Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced to help maintain correct refrigerant control and cooling efficiency.
