A used genuine OEM Audi upper radiator coolant hose, OEM part number 8K0121101J. This hose, also known as a coolant line, carries hot coolant from the engine to the radiator for heat exchange. It's designed for 3.0L and 3.2L V6 engines, including the supercharged 3.0L. A common failure symptom is a visible crack or leak at the hose's connection points, which can cause overheating and coolant loss.
