A used OEM Audi coolant/water hose, part number 079121055AG, is a genuine factory component for the left side of the engine bay. This hose carries coolant through the turbocharged 4.0L V8 (3993cc) found in models like the Audi S6, S7, and A8 Quattro. A failing hose can cause a visible coolant leak, leading to overheating and potential engine damage.
