Cylinder Head Coolant Vent Pipe, BMW - F10 550i, F13 650i, F02 750i, X5/X6 50i (N63TU)
Y-shaped cooling hose is a potential leak point on N63TU. Genuine replacement for BMW part #17127619702. 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 this hose is plastic and prone to cracking and leaking near the turbos. 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 is a Genuine BMW N63TU vent pipe with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
