About the Molded Coolant Hose Product Line

The Molded Coolant Hose line by Gates focuses on precision-engineered hoses that feature molded shapes and integrated connectors to fit specific vehicle applications. This product line enhances coolant system reliability by reducing the risk of leaks and simplifying installation with modular components such as branches and quick connectors.

With multiple centerline length measurements (13.5 mm, 22 mm, and 343 mm) and consistent inside diameters of 17 mm (0.68 inches) on both ends and 21.7 mm (0.855 inches) on the branch, this hose supports efficient coolant flow and system integrity.

Common Applications and Problem Solving

  • Replacement of worn or cracked radiator coolant hoses on Jaguar S-Type
  • Resolving coolant leaks caused by deteriorated or damaged hoses
  • Maintaining proper coolant circulation to prevent engine overheating

  • Addressing coolant system failures related to hose fitting or connection issues

Installation Notes and Tips

Ensure the engine is cool before removing the old coolant hose to avoid burns. Verify that the hose ends and connectors match the vehicle’s specifications. The molded design and integrated female quick connector simplify installation, but proper seating and secure attachment are essential to prevent leaks. Inspect all clamps and fittings during installation and replace if necessary.
