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. ## Frequently Bought Together - ACDelco Professional 38103 Drive Belt Tensioner Assembly with Pulley - ACDelco Gold 6K960 Standard V-Ribbed Serpentine Belt --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/404683745-acdelco-38103-professional-automatic-belt-tensioner-and-pulley-assembly](https://www.desertcart.hk/products/404683745-acdelco-38103-professional-automatic-belt-tensioner-and-pulley-assembly) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-09-23*
