Detailed Product Description

This radiator coolant hose features a molded construction that ensures a secure and leak-resistant connection between the radiator and engine cooling system components.

Installation Notes and Tips

Ensure the engine is cool before removing the old hose to avoid burns. Verify the hose orientation matches the original part, noting the different diameters on each end.

Inspect surrounding components for wear during installation to maintain overall cooling system integrity.
