This used OEM Audi coolant hose / line (4H0121062B) was removed from a donor vehicle. Designed for the 4.0L V8 twin-turbo engine found in the Audi A8 Quattro and S8, this genuine hose carries engine coolant between components. Over time, the rubber can develop cracks or become brittle, causing coolant leaks that may lead to overheating if not addressed.
