This used OEM BMW heater core coolant hose / line (part number 6909240) carries coolant between the engine and the heater core, and it was removed from a Z4. When this hose develops a leak, it can cause low cabin heat and coolant loss under the dashboard. Also referred to as the heater core coolant line.
