BMW B46 B47 B48 Upgraded Aluminium Engine Coolant Hose Flange - BMW 11118511205

This coolant hose flange connects the upper radiator hose at the engine block. This flange is a known failure point and can break by either attempting to disconnect the upper radiator hose or failing on its own. Major coolant leaks on the left side of the engine could be related to this flange.

Our upgraded aluminum flange improves on the original plastic design to ensure maximum reliability in the future.

Includes required seal between the engine block and flange
