Original BMW Engine Coolant Outlet Flange for BMW 335d and X5 xDrive35d (2009–2013)

The Original BMW engine coolant outlet flange is the plastic connector on the left side of the engine block that carries coolant out of the M57N2 diesel in the BMW 335d and X5 xDrive35d. BMW's parts data names it simply a connector. It weighs 78 g, is made in Germany, and has been in production since March 2007. Because the body is plastic, years of constant heat cycles can stress-crack it and open a serious coolant leak. On any engine, an outlet flange like this sits where hot coolant leaves the block, joining the internal passages to the hoses that run toward the radiator.

Original BMW Parts carry a 24-month parts warranty.

This number replaced the earlier connector 11-12-2-247-744. BMW marks the change as exchangeable retrospectively, so the current part is the correct replacement on cars that left the factory with the older number. BMW's parts data lists the same connector across M47N, M57, and M57N2 diesel applications. For the cars PMB supplies it for, the relevant applications are the E90 335d and the E70 X5 diesel, both with the M57N2 engine.
