A used genuine Audi coolant/water hose, OEM number 8W0121449AN, also superseding 8W0122449AS. This hose routes coolant through the 3.0L V6 (supercharged or turbocharged) engine bay. Over time, these hoses can crack or develop pinhole leaks, leading to coolant loss and potential overheating if not replaced promptly.
