What It Is Used For

• Restoring refrigerant metering after an A/C service event
• Addressing uneven evaporator cooling in GM compact vehicles
• Replacing a restricted or worn expansion valve during system repair
• Supporting proper refrigerant flow control in the evaporator circuit
• Servicing A/C systems on Chevrolet Aveo, Aveo5, Pontiac G3, and Pontiac Wave models

Installation Notes and Tips

Verify the vehicle’s model year and design revision before ordering, especially on 2011 Chevrolet Aveo and Aveo5 applications noted as first design with O-ring. Inspect the A/C system for contamination, leaks, and damaged seals before installation. Because the manufacturer recommends replacing the expansion valve/orifice tube each time the A/C system is serviced, confirm the rest of the system is clean and properly evacuated before recharging.

Quality Assurance

Global Parts supplies this expansion valve as a service replacement for the listed GM and Isuzu applications. The manufacturer notes that the valve is intended to be replaced during A/C service to help maintain proper system operation.
