Installation Notes and Tips

Use this hose as a direct replacement for the upper radiator hose assembly on the listed Volkswagen and Audi applications. Confirm the hose routing, connector style, and branch layout against the removed part before installation. Because the assembly is application-specific, it is designed to install without cutting or reshaping.

For best results, inspect mating surfaces and replace worn seals or connectors as needed during cooling system service. Verify that the quick connect fitting seats fully and that the hose is routed away from heat sources and moving components.
