A used genuine Audi Radiator Coolant Hose (OEM 4H0121101AD) is a right-side coolant line removed from a donor vehicle. This hose circulates coolant between the radiator and the 4.0L twin-turbo V8 found in Audi A8 and S8 models. Over time, the rubber can crack or the quick-connect fittings can leak, leading to coolant loss and overheating.
