This is a used OEM Audi Coolant Hose, part number 4M0121448AG, removed from a donor vehicle. This hose is also known as a water hose or radiator hose, and it connects the coolant system components on the 3.0L diesel and gas engines found in the Audi Q7. The part is designed for the 3.0L V6 Diesel (2967cc), the 3.0L V6 Gas Supercharged (2995cc), and the 3.0L V6 Mild Hybrid (MHEV) Turbocharged engines. A failure of this hose typically results in a coolant leak, leading to low coolant levels and potential engine overheating.
