This used Audi coolant reservoir (OEM 4F0121403N) is a genuine service part pulled from a donor vehicle. Also known as a coolant tank or bottle, it directly replaces numbers 4F0121403G, 4F0121403C, and 4F0121403R. Designed for the 2.8L and 3.2L V6 engines found in the Audi A6 and A6 Quattro, this plastic tank holds overflow coolant and can develop cracks or leaks over time, leading to low coolant levels and potential overheating.
