The upper radiator coolant hose, OEM part number 8W0122101BH, is a genuine factory-original component designed for optimal performance in various Audi models, including the A4, A4 Quattro, A5, A5 Quattro, and A5 Sportback from years 2017 to 2023. This essential water hose facilitates coolant flow from the engine to the radiator, ensuring effective temperature regulation and preventing overheating. Common issues resolved by replacing a worn or damaged hose include leaks, reduced coolant circulation, and engine overheating. It is critical to note that this part should be paired with new couplings as related components cannot be reused.
