BMW Coolant Expansion Tank Hose / Line, OEM 7644103, is a genuine used part from a donor vehicle. This hose connects the coolant expansion tank in the engine bay. It fits the BMW X5 equipped with the 2.0L turbocharged plug-in hybrid engine (PHEV). Also known as a coolant line, this component circulates coolant and can develop cracks or leaks over time, leading to coolant loss, low coolant warnings, or overheating. A replacement restores proper cooling system function.
