A used genuine OEM Audi 4G0122101BC upper radiator coolant hose / line, pulled from a donor vehicle. This coolant hose—also known as the upper coolant line—routes coolant between the radiator and the engine on Audi models equipped with the supercharged 3.0T V6 (2995cc). If the hose cracks or leaks, the engine can overheat and lose coolant rapidly.
