How It Works

The expansion valve meters refrigerant into the evaporator at a controlled rate, helping the A/C system manage pressure drop and cooling performance. For Chevrolet Corvette and Cadillac XLR service work, part number 3411873 is a practical replacement when the original valve is being serviced or replaced.

Common A/C Issues It May Address

• Weak or inconsistent cabin cooling
• Improper refrigerant metering at the evaporator
• A/C performance loss after system service
• Restricted refrigerant flow in the HVAC circuit
• Service replacement for worn expansion valve components

Installation Notes

Verify the vehicle year and application before installation. For 2005-2010 Chevrolet Corvette and 2004-2009 Cadillac XLR models, confirm the system contains OEM inline filter 3441242. Replace the expansion valve/orifice tube during A/C service as recommended by the manufacturer, and evacuate and recharge the system according to factory procedures.

Quality Assurance

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