Auxiliary Radiator Hose, BMW - F10 550i, F13 650i

Cooling hose running from the auxiliary radiator to the main radiator on 2011-2013 F10 550i and 2012 F12/F13 650i. This hose is used on early models of the N63 V8 engine produced for those years only. These models use the N63 engine, not the N63TU engine that came out in 2013. Note the years as the cooling system was re-designed on the later models.

Rubber hoses are ideal when new, as they allow some movement and flexibility during driving. The only problem is that they begin to degrade as they age, and can eventually fail, leaving you with the potential for loss of control from coolant spilling and/or an overheating situation. Replace your radiator hoses as a preventative measure before they fail in order to save you from further headaches and expenses.

This is a Genuine BMW N63 coolant hose 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.
