Global Parts A/C Expansion Valve for Impala

Global Parts part 3411598 is an A/C expansion valve for select Chevrolet Impala and Impala Limited applications. It regulates refrigerant flow before the evaporator so the system can use refrigerant cooling capacity efficiently.

How It Works

This expansion valve slows refrigerant entering the evaporator, helping the A/C system manage pressure and temperature across the cooling circuit. Part number 3411598 is a practical replacement when servicing the HVAC system on a Chevrolet Impala or Chevrolet Impala Limited, especially when the original valve is restricted or no longer meters refrigerant correctly.

Common A/C Problems It Can Address

• Weak cabin cooling
• Uneven evaporator performance
• Restricted refrigerant flow
• Incorrect A/C pressure behavior
• Service-related replacement on a Chevrolet Impala or Impala Limited

Installation Notes

Replace the expansion valve during A/C service when the system is opened. Recover refrigerant, evacuate the system, and verify proper sealing before recharging. Confirm the vehicle application by year, model, and configuration before installation. Part number 3411598 should be matched to the listed fitment for 2012-2013 Chevrolet Impala and 2014-2016 Chevrolet Impala Limited applications.

Quality Assurance

Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced. That guidance supports consistent refrigerant metering and helps maintain proper HVAC system operation after repair.
