Global Parts 3411790 A/C Expansion Valve - Front

Honda and Acura A/C Expansion Valve

Global Parts 3411790 is an A/C expansion valve for select Honda and Acura applications. It meters refrigerant flow before the evaporator so the system can use cooling capacity efficiently, making it a direct-fit service part for common HVAC repairs on the Honda Pilot, Honda Ridgeline, and Acura MDX.

How It Works

The expansion valve reduces refrigerant pressure and regulates flow as the refrigerant enters the evaporator. That pressure drop helps the evaporator absorb heat more effectively, which is essential for stable cabin cooling. Global Parts 3411790 is a practical replacement when servicing the A/C system on a Honda Pilot, Honda Ridgeline, or Acura MDX.

Common Repair Symptoms

• Weak or inconsistent A/C cooling
• Incorrect refrigerant metering at the evaporator
• Compressor cycling concerns related to flow restriction
• Uneven vent temperatures in the cabin
• HVAC service needs on Honda Pilot, Honda Ridgeline, or Acura MDX models

Installation Notes

Replace the expansion valve during A/C system service when the system is opened for repair. Verify the vehicle application by year, make, model, and position before installation. Proper evacuation, leak checking, and refrigerant recharge procedures should be followed 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.
