Cylinder Head Coolant Vent Pipe, Rein - F10 550i, F13 650i, F02 750i, X5/X6 50i

Coolant leaks near the turbos on the N63 engine may be traced to this vent pipe for the cylinder heads. The Y connection on the original hose was plastic and prone to cracking and leaking near the turbos. This hose addresses this weakness with an upgraded metal fitting!

This coolant pipe / hose was used on early models of the N63 V8 engine: 2011-2013 F10 550i, 2012 F12/F13 650i, and 2009-2012 F01/F02 750i. These models use the N63 engine (N63A), and not the N63TU engine that came out in 2013. Note the years as the cooling system was re-designed on the later models. 

This is an OEM N63 vent pipe manufactured by Rein Automotive - an original supplier to BMW for this part, as well as many other engine and cooling components. As an OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
