This genuine Audi upper radiator hose (OEM 8K0121101M) is a factory coolant hose removed from a donor vehicle. Also called a radiator line or upper hose, it circulates coolant between the engine and radiator on models equipped with 1.8L or 2.0L turbocharged four-cylinder engines. Over time, the rubber can crack or the fittings weaken, leading to coolant leaks and potential overheating.
