Detailed Product Information

Rein CHR0665 is engineered to match the original radiator hose layout used on upper cooling-system applications. The hose follows the OE branch shape and connector style, which supports a precise replacement on 2013-2018 Volkswagen Jetta upper and upper main radiator positions, 2014-2017 Volkswagen Beetle upper and upper main radiator positions, and 2014-2017 Volkswagen Passat upper applications. This part cross-references Genuine 5C0122101AA for the same application.

For buyers searching for a Volkswagen Jetta upper radiator hose, Volkswagen Beetle upper coolant hose, or Volkswagen Passat upper radiator hose, CHR0665 provides an OE-style solution built around the original fitment requirements. The black EPDM hose measures approximately 22 inches in centerline length and uses application-specific end dimensions to match the factory routing.

Common Problems This Hose Can Address

• Coolant leaks from a worn or damaged upper radiator hose
• Fitment issues caused by trimming or adapting a universal hose
• Repeat leaks from reusing old quick connectors or O-rings
• Cooling-system service delays from incorrect hose shape or branch layout
• Heat-related hose deterioration in the engine bay

Installation Notes and Tips

CHR0665 is an application-specific hose assembly, so no cutting, refitting, or adjusting of the hose is required. Inspect the mating connections and sealing surfaces before installation, and replace worn quick connectors or O-rings as needed to avoid repeat leaks. Confirm the vehicle position and engine-side routing against the listed fitment before installation on Volkswagen Jetta, Beetle, or Passat models.
