Common A/C Issues This Part Can Address

• Weak cabin cooling from incorrect refrigerant metering
• Uneven evaporator performance during A/C operation
• Restricted refrigerant flow caused by a worn expansion valve
• Service-related A/C performance loss after system repair
• Pressure control issues in the evaporator feed circuit

Installation Notes

Replace the expansion valve/orifice tube during A/C service when the system is opened or repaired. Clean the system thoroughly and verify refrigerant charge, seals, and operating pressures before returning the vehicle to service. Confirm vehicle application by year, make, and model before installation.

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.
