Detailed Description

This Gates coolant hose is engineered as a permanent replacement for molded radiator hoses in demanding cooling-system layouts. The flexible design and built-in spiral wire help the hose maintain shape while routing coolant through tight or unusual configurations. For heavy-duty truck and bus service, Gates 26601 provides a practical solution when a standard molded hose does not match the original path. It is a direct-fit style service part for applications that call for a 1.75-inch hose connection and a 6-inch centerline length. If you are sourcing a radiator coolant hose for Ford truck or bus cooling repair, this part number is commonly searched as Gates 26601.

This part cross-references Dayco 81281 for the same application.

Common Cooling Problems It Can Address

  • Cracked or split radiator hose sections
  • Collapsed hose routing under heat and vacuum conditions
  • Incorrect molded hose shape for a heavy-duty cooling layout
  • Coolant leaks at worn hose connections
  • Service replacement needs on truck and bus cooling systems

Installation Notes and Tips

Verify the hose inside diameter, centerline length, and routing path before installation. Match the hose to the original coolant flow path and inspect adjoining necks, clamps, and fittings for wear or corrosion. Because this is a flexible hose with steel reinforcement, proper alignment during installation helps maintain clearance and reduce stress at the ends. Confirm fitment against the vehicle’s cooling system requirements before final assembly.

Quality Assurance

Gates is known for cooling-system components used across heavy-duty service applications. Part number 26601 is built as a replacement coolant hose for radiator service where flexible routing and molded-hose substitution are required.
