Common Repair Symptoms
- Weak or inconsistent cabin cooling
- Incorrect evaporator refrigerant metering
- A/C pressure imbalance across the system
- Temperature swings from the vents
- Restricted flow caused by a failing expansion valve
Installation Notes
Verify refrigerant type, port style, and vehicle fitment before installation. Inspect the mating surfaces and replace damaged O-rings or contaminated components as needed during A/C service. Confirm the system is clean and properly evacuated before charging to help the new valve operate at the specified superheat setting.
