This BMW heater coolant hose (OEM 9124729) carries engine coolant to the heater core. Also known as a heater coolant line, it's a genuine used part from a donor vehicle. On 3.0L six-cylinder and 4.4L V8 engines in certain BMWs, this hose sees constant heat cycling; a cracked hose leaks coolant and kills cabin heat. Replace it promptly when you spot dampness or white crust near the bulkhead connection.
