Product Details

This Gates Molded Coolant Hose is engineered for lower cooling system routing on select Volkswagen and Audi platforms. The molded design helps match factory hose geometry, while the integrated features support the original cooling system layout found on vehicles such as the Volkswagen Jetta, Golf, and GTI, as well as the Audi A3 and A3 Quattro. Part number 51835 is also referenced by OE-style cross numbers 5Q0122051BF and 5Q0122051CT for the same application.

The Gates Molded Coolant Hose product line focuses on application-specific assemblies that mirror OE requirements, including molded branches, quick-connect fittings, sensors, and restrictor-style components where equipped. This makes 51835 a practical choice when replacing a lower radiator hose on a Volkswagen Golf lower hose application or a Volkswagen GTI lower coolant hose application.
