Cylinder Head Coolant Vent Pipe Upgrade, URO - F10 550i, F13 650i, F02 750i, X5/X6 50i (N63TU)

Coolant leaks near the turbos on the N63TU engine may be traced to this vent pipe for the cylinder heads (it's a big problem on the early N63 which uses a near identical fitting). The Y connection on the factory hose is plastic and prone to cracking and leaking near the turbos. This URO Premium version is upgraded with an aluminum Y connection.

This pipe part number is only for the later N63TU engines used in 2014-2016 F10 550i, 2013-2017 F12/F13 650i, 2013-2015 F01/F02 750i, 2014-2018 F15 X5 50i, and 2014-2019 F16 X6 50i. These models use the updated N63TU engine, not the original N63 engine that came out in 2009. Note the years as the cooling system was re-designed on the later models.

This part is listed by BMW as BMW part number 17127619702 (17-12-7-619-702) and is described as URO Premium Coolant Vent Hose, N63TU.
