Transmission Cooler Hose, Rein - F10 550i, F13 650i

Transmission cooler hose running from the cooler to a hard pipe and onto the transmission. This hose is used on early models of the N63 V8 engine: 2011-2013 F10 550i and 2012 F12/F13 650i. 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 an OEM transmission cooler hose manufactured by Rein - an original supplier to BMW for many cooling system and engine 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.
