How This Part Works

The expansion valve/orifice tube reduces refrigerant flow before it reaches the evaporator, allowing the system to use the refrigerant’s cooling capacity more effectively. Global Parts 3441237 is recommended whenever the A/C system is serviced, especially on Chevrolet Suburban, Cadillac Escalade, Chevrolet Trailblazer, and GMC Envoy platforms with condenser liquid outlet fitment.

Common Problems It Can Address

• Restricted refrigerant flow at the condenser liquid outlet
• Reduced cabin cooling performance after A/C service
• Uneven evaporator feed caused by a worn or contaminated screen
• System contamination found during expansion valve/orifice tube service
• Loss of cooling efficiency in GM truck and SUV A/C systems

Installation Notes

Install during A/C system service and verify the condenser liquid outlet configuration before ordering. Replace the expansion valve/orifice tube as part of a proper refrigerant circuit inspection, and confirm the system is evacuated and recharged according to vehicle service procedures.

Quality Assurance

Global Parts 3441237 is built for the listed GM and Isuzu fitments and follows the manufacturer’s service recommendation for replacement during A/C maintenance.
