Detailed Product Overview

Rein CHE0170 is engineered as a replacement water hose for European vehicles where the factory hose includes molded branches and quick connectors. The hose matches the OE layout, including branch shape and connector style, to help maintain proper routing and sealing in the cooling circuit. For Volkswagen Golf and Volkswagen Jetta applications, this part number supports a clean replacement at the throttle body to cylinder head connection without modifying the hose to make it fit.

This part cross-references OE number 1J0122157DN for the same application. Search terms such as Volkswagen Golf throttle body to cylinder head coolant hose, Volkswagen Jetta branched water hose, and Rein CHE0170 OE replacement hose all point to this exact style of repair part.

Common Problems This Hose Can Address

• Coolant leaks at aged hose connections
• Cracked or hardened EPDM hose material
• Fitment issues caused by reused quick connectors or o-rings
• Extended repair time from trimming or refitting a universal hose
• Cooling system service on a Volkswagen Golf or Jetta with the original branched hose layout

Installation Notes and Tips

Verify the vehicle application, hose routing, and connector style before installation. This hose is application-specific and is shaped for the OE routing, so it should be installed as a direct replacement rather than modified to fit. Inspect mating surfaces and related seals during service to help prevent repeat leaks.
