Expert Recommendation
Why FEBI? In BMW group plastic cooling equipment, Febi is the most reliable brand in the world that offers the same tolerance values as the original part.
Important Application Note: Perform the air bleeding process when the engine is **cold**. Do not apply excessive force when tightening the screw; a quarter turn after the seal sits on the surface is sufficient for sealing. Over-tightening may cause the screw to break and remain in the socket.
