Installation Notes

Replace the O-rings during service and verify the sealing surfaces are clean before assembly. Confirm the vehicle uses R134 refrigerant and match the valve to the exact BMW application, including front-position and climate-control notes where listed. Evacuate and recharge the system to specification after installation, then check for leaks and proper vent temperature.
