This used OEM Audi Auxiliary Radiator Coolant Hose / Line (4M0145920AD) came off a donor vehicle. It’s the left-side coolant line that circulates fluid through the auxiliary radiator on 3.0L V6 diesel, gasoline, and mild hybrid engines. A cracked hose can cause coolant leaks, low fluid levels, and potential overheating.
