Product Details

Rein CHR0740 is engineered as an OE-quality radiator coolant hose for European vehicles where factory-style fit and connector design matter. The hose follows the original manufacturer’s dimensions and branch shape, with thermoplastic quick-connect fittings that match the OE configuration. That makes it a practical replacement for a worn, cracked, or leaking upper radiator hose on applications such as the 2008-2014 Volkswagen GTI, 2008-2013 Audi A3, and 2012-2013 Volkswagen Beetle. This part number, CHR0740, is also listed for additional Volkswagen upper hose applications including the Golf, Jetta, and Eos.

This part cross-references Genuine (e.g., 1K0122101KS) for the same application.

Common Problems This Hose Can Address

• Coolant leaks at the upper radiator hose connection.
• Cracked or heat-aged hose material.
• Damaged quick-connect fittings or worn O-rings.
• Poor sealing from reused original connectors.
• Fitment issues caused by non-OE hose shape or branch layout.

Installation Notes

Verify the vehicle’s upper hose routing and connector style before installation. Because this is an application-specific hose, it installs without cutting or reshaping the hose assembly. Inspect mating surfaces, quick connectors, and sealing points for wear before assembly to help ensure a proper seal.
