What It Is Used For
- Replacing a worn or cracked molded coolant hose.
- Restoring coolant flow in an upper radiator hose route.
- Addressing leaks caused by heat-aged EPDM hose material.
- Correcting fitment issues from a hose that no longer holds its molded shape.
Installation Notes and Tips
Verify the hose routing, end diameters, and centerline length against the removed part before installation. Confirm the upper position and molded profile match the vehicle’s cooling layout. Inspect adjoining necks and clamps for wear or corrosion before installing the new hose.
Quality Assurance
