Installation Notes and Tips

Verify the vehicle’s refrigerant type, connection style, and port sizes before installation. Replace the valve only after the system has been properly evacuated and inspected, and confirm that the mating surfaces are clean and undamaged. On a 1997 Subaru Impreza A/C repair, matching the block-type layout and O-ring connection style is important for proper sealing and refrigerant control.
