It is very common for this expansion tank to get brittle and crack over time, leaking coolant, causing overheating, and potentially stranding you on the side of the road. The constant hot/cold temperatures and positive pressure of the cooling system stress the plastic until eventually a crack develops. If you are replacing any other part of the cooling system in the E65, we suggest inspecting and replacing this tank as a preventative measure.
This is an expansion tank manufactured by Rein (CRP) Automotive - an original supplier to BMW for many cooling system 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.
