This used OEM coolant hose / line (Audi part number 4G0121447BC) was removed from a donor vehicle. It's the genuine factory coolant hose for the 4.0L 3993cc V8 gas DOHC turbocharged engine found in the Audi S6 and S7. As the coolant hose circulates coolant to manage engine and turbo temperatures, a failing part often causes visible leaks, low coolant warning, or overheating.
