Global Parts 3411520 A/C Expansion Valve

A/C Expansion Valve for Toyota Prius Applications

Global Parts 3411520 is an A/C expansion valve for select Toyota Prius, Prius V, Prius Plug-In, and Pontiac Vibe applications. It meters refrigerant flow before the evaporator so the system can use refrigerant cooling capacity efficiently.

• OE-style A/C expansion valve for HVAC refrigerant control
• Fits 2010-2015 Toyota Prius
• Fits 2012-2017 Toyota Prius V
• Fits 2012-2015 Toyota Prius Plug-In
• Fits 2010 Pontiac Vibe
• Part number 3411520 for direct reference

How It Works

This expansion valve reduces refrigerant pressure and regulates refrigerant delivery into the evaporator. That control is important for stable vent temperatures and consistent A/C performance in Toyota Prius and Prius V systems. This part cross-references DENSO Auto Parts (e.g., 475-2107) for the same application.

Common A/C Problems It Can Address

• Weak or inconsistent cabin cooling
• Improper refrigerant metering at the evaporator
• Erratic A/C outlet temperatures
• Reduced system efficiency after A/C service
• Expansion valve wear in Toyota Prius, Prius V, and Prius Plug-In HVAC systems

Installation Notes

Verify the vehicle year and model before ordering. Replace the expansion valve/orifice tube during A/C service when the system is opened, and inspect related HVAC components for contamination or restriction. Confirm the correct refrigerant service procedure for the vehicle before recharging the system.

Quality Assurance

Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced. Part number 3411520 is cataloged for the listed Toyota Prius, Prius V, Prius Plug-In, and Pontiac Vibe applications.
