Additionally, it can show cracks and fraying around the edges or a glazed (shiny) appearance. They’re signs it’s time to change the belt. **Q: What about the tensioner pulley?** A: The tensioner pulley complements the drivebelt and is also subject to wear and possible replacement. Signs it may need replacement include squealing sounds or, if the bearing is failing, a grinding sound while the engine is running. **Q: What are signs of a failing radiator hose?** A: A worn or failing radiator coolant hose often develops cracks that lead to leaks. Evidence for that includes drips or puddles beneath the radiator or engine, along with the odor of coolant. The engine may also overheat. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as it should *by A***R on March 6, 2026* Good quality product ### ⭐⭐⭐⭐⭐ Excellent tensioner *by R***K on April 20, 2026* Excellent tensioner.
