Genuine Audi lower radiator coolant hose / line OEM 4F0121109F, a used OEM part removed from a donor vehicle. Also referred to as the coolant hose, it routes fluid from the radiator to the engine on naturally aspirated 2.8L and 3.2L V6 models of the A6 and A6 Quattro. A cracked or deteriorated hose can cause coolant leaks and engine overheating, making timely replacement critical.
