This used OEM Audi coolant hose (4H0121059H) was removed from a donor vehicle. Also known as a coolant line, it carries engine coolant through the cooling system. This hose is specific to the 3.0L supercharged V6 (EA837) found in the Audi A8 Quattro. A failing coolant hose can develop cracks or leaks, leading to coolant loss and potential engine overheating.
