Audi Water Hose Set 4H0122447, also known as the Coolant Hose Set, is a genuine used OEM part removed from a donor vehicle. Designed for the 4.0L 3993CC twin-turbo V8, this set of hoses carries coolant between the engine, radiator, and heater core. Over time, these hoses can develop leaks, cracks, or swelling, leading to coolant loss and potential overheating. Replacing a deteriorated set restores proper cooling system function.
