This used Audi radiator coolant hose, OEM part number 4F0145923A, is a genuine factory line removed from a donor A6 Quattro. Also referred to as a coolant hose or line, it routes coolant between the radiator and the engine on 3.0L supercharged V6 models. Over time, these hoses can develop leaks or cracks from heat cycling, leading to coolant loss and potential overheating if not replaced.
