Audi Upper Radiator Coolant Hose / Line, OEM number 4G0122101AT, is a genuine used part originally removed from a salvage donor. This coolant hose, also called the upper radiator coolant line, directs coolant from the radiator to the engine on 1.8L and 2.0L turbocharged four-cylinder Audi A6 and A7 Quattro models. When the hose develops a leak, you'll likely notice low coolant levels and potential engine overheating—a common failure on these cars.
