This is a used OEM BMW coolant overflow vent hose, part number 8602676, removed from a donor vehicle. Also known as the coolant overflow line, this hose vents excess pressure and hot coolant from the expansion tank back to the system. A failure here can cause a visible coolant leak or steam under the hood, particularly on 4.4L V8 turbocharged engines.
