A used genuine OEM Audi coolant hose / water hose, OEM part number 4G0121056AH, also replaces 4G0121056AF. This hose routes engine coolant on 1.8L and 2.0L turbocharged four-cylinder engines. Over time, the rubber can crack or develop pinhole leaks, causing coolant loss and potential overheating. A direct replacement for the factory hose on compatible Audi models.
