Detailed Description

Rein Automotive coolant hoses are engineered as OE-quality replacements for European vehicles, with sizing and shape that follow the original hose layout. CHR0904 is built to match the factory connection geometry, including the branch and fitting dimensions needed for a proper coolant path between the flange and water pump. For owners searching for a Volkswagen Jetta coolant hose or Volkswagen Golf engine coolant hose, this part provides a direct-fit service replacement.

The molded EPDM construction is suited for cooling-system use, while the specified end diameters help confirm fitment before installation. Use CHR0904 when replacing a worn, cracked, or leaking hose on the cooling circuit of the listed Volkswagen applications.

Common Reasons for Replacement

• Coolant seepage at the hose or connection point
• Cracking, hardening, or swelling of the hose material
• Loss of cooling-system pressure from a deteriorated hose
• Damaged or aged OE hose assembly on the flange-to-water-pump route
• Service replacement for a Volkswagen Jetta or Golf coolant hose

Installation Notes and Tips

Verify hose routing, end diameters, and the flange-to-water-pump position before installation. Inspect adjoining clamps, flanges, and water pump connections for wear or corrosion, and replace any damaged sealing surfaces as needed. Confirm the hose is seated fully and routed without twist or tension to maintain proper coolant flow.

Quality Assurance
