Audi Coolant / Water Hose, OEM part number 06E121545C, is a genuine used hose from a donor vehicle. This hose carries engine coolant between components in the cooling system. A common failure symptom is a visible crack or leak, which can cause overheating and low coolant levels. It fits multiple 3.0L V6 engine configurations, including the 3.0T supercharged and diesel turbocharged variants found in Audi A4 through Q7 models.
