The BMW coolant expansion tank hose/line set (OEM 7634257) is a used genuine part removed from a donor vehicle. This hose set, also referred to as a coolant expansion tank line set, routes coolant between the expansion tank and the engine cooling system. On the 4.4L turbocharged V8, cracks or leaks in these hoses can cause coolant loss and potential overheating.
