Audi auxiliary radiator hose / line, OEM 8E0121058, is a used genuine part removed from a donor vehicle. This left-side coolant hose routes fluid to the auxiliary radiator on the 4.2L 4163CC V8 (naturally aspirated) in the Audi S4. When the hose develops cracks or leaks, it can cause coolant loss and overheating.
