The OEM BMW Coolant Expansion Tank Hose, part number 7648187, is a used genuine line removed from a donor vehicle. Also referred to as the coolant expansion tank line, this hose routes coolant between the reservoir and the engine, keeping the cooling system pressurized. Over time, the plastic fitting or rubber can crack, leading to coolant loss, overheating, and potential engine damage. This specific hose fits 3.0L turbocharged I6 and 4.4L turbocharged V8 engines.
