A used BMW coolant tank overflow hose (line), OEM part number 7933658, is a genuine factory hose that routes excess coolant from the expansion tank back to the system as pressure and temperature fluctuate. This rubber line is specific to BMW’s 4.4L N63 V8 engine family, found in 750i xDrive, M550i xDrive, and M850i xDrive models. A cracked or collapsed overflow hose can cause visible coolant loss, low-level warnings, or air pockets in the cooling circuit, leading to overheating.
