Global Parts 3411351 A/C Expansion Valve - Front

A/C Expansion Valve for OE-Style Refrigerant Control

Global Parts 3411351 is an A/C expansion valve/orifice tube that slows refrigerant before it enters the evaporator, helping the system use cooling capacity more effectively. It is a direct-fit service part for select Cadillac CTS, Honda Pilot, Acura MDX, and Honda Odyssey applications.

• OE-style A/C flow restrictor for refrigerant metering at the evaporator
• Helps regulate refrigerant flow in the HVAC system
• Fits 2008-2010 Cadillac CTS, N/A
• Fits 2003-2005 Cadillac CTS, N/A
• Fits 2003-2007 Honda Pilot, Front
• Fits 2001-2006 Acura MDX, Front
• Fits 1999-2004 Honda Odyssey, Front

How It Works

The expansion valve/orifice tube is a key A/C flow restrictor that reduces refrigerant pressure before the evaporator. That pressure drop allows the refrigerant to absorb heat more effectively, which is essential for stable cabin cooling. Global Parts 3411351 is a practical replacement choice when servicing the A/C system on a Honda Pilot, Acura MDX, or Honda Odyssey, as well as select Cadillac CTS models.

This part cross-references DENSO Auto Parts (e.g., 475-0506, 475-2004) for the same application.

Common A/C Problems It May Address

• Weak or inconsistent vent air temperature
• Restricted refrigerant flow through the evaporator circuit
• Reduced cooling performance after A/C service
• System performance issues tied to a worn metering component

Installation Notes

Replace the expansion valve/orifice tube during A/C service, especially when the system has been opened for repair. Verify the vehicle application by year, make, model, and position before installation. Clean the system as needed and follow the correct evacuation and recharge procedure after service.

Quality Assurance

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