The Audi 5N0122073AA Coolant Hose / Line is a used genuine OEM part, removed from a donor vehicle. This hose carries engine coolant between the turbocharged 2.0L (1984cc, EA888 family) engine and the cooling system on the Audi Q3 and Q3 Quattro. Over time, coolant hoses can develop cracks, swelling, or leaks, leading to coolant loss and potential overheating. A failing hose often leaves visible stains or a sweet smell, and may cause the low-coolant warning to illuminate.
