Audi Coolant Hose / Line with OEM number 8W0121471B is a used genuine part sourced from a donor vehicle. This hose circulates coolant through the cooling system on 3.0L 2995CC V6 engines—both supercharged and turbocharged—found in the S4, S5, and S5 Sportback. Also known simply as a coolant line, it can develop cracks or leaks over time, leading to coolant loss, overheating, and steam from the engine bay. Timely replacement restores proper flow to prevent engine damage.
