Review: Works just fine. - Bought this for my 2005 mustang gt 4.6. Fits perfectly and works great. Same quality as the local auto parts store but a little cheaper if you don’t mind waiting a couple of days. I wasn’t in a hurry at all so worked out perfectly for me. Would recommend. ## Features - Helps keep the drive belt properly aligned and routed.Material:steel - Some ACDelco Gold parts may have formerly appeared as ACDelco Professional - Premium aftermarket replacement part - Manufactured to meet specifications for fit, form, and function for General Motors vehicles as well as most makes and models ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000C9KQSA | | Best Sellers Rank | #5,773 in Automotive ( See Top 100 in Automotive ) #1 in Automotive Replacement Idler Pulleys | | Brand | ACDelco | | Customer Reviews | 4.6 4.6 out of 5 stars (2,451) | | Date First Available | October 10, 2007 | | Exterior | Machined | | Is Discontinued By Manufacturer | No | | Item Weight | 10.2 ounces | | Item model number | 38001 | | Manufacturer | ACDelco | | Manufacturer Part Number | 88909582 | | Model | ACDelco - Idler Pulley (B) (38001) | | OEM Part Number | 88909582 | | Product Dimensions | 3.6 x 3.6 x 2 inches | ## Images ![ACDelco Gold 38001 (88909582) Idler Pulley - Image 1](https://m.media-amazon.com/images/I/61jExXH38UL.jpg) ![ACDelco Gold 38001 (88909582) Idler Pulley - Image 2](https://m.media-amazon.com/images/I/61RYDd83nIL.jpg) ## Questions & Answers **Q: Why is it important to have belts and hoses replaced periodically?** A: If a drivebelt or radiator coolant hose fails while driving, you won’t be able to continue driving — and additional engine damage may occur if the engine overheats. **Q: How long do belts and hoses typically last?** A: Lifespans of belts and hoses vary based on factors including the climate and driving habits, but generally a drivebelt (also known as a serpentine belt) lasts about 50,000-100,00 miles, while radiator coolant hoses can last about five years. **Q: What are signs the drivebelt needs replacement?** A: A worn drivebelt can slip while the engine is running, causing high-pitched squealing or chirping sounds. 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 ### ⭐⭐⭐⭐⭐ Smooth Performance and Excellent Build Quality *by M***L on November 20, 2025* This ACDelco Gold idler pulley is top‑notch.

The pulley is good quality but wasn’t the problem. ## Frequently Bought Together - ACDelco Gold 38001 Idler Pulley - ACDelco Gold 38158 Drive Belt Tensioner Assembly with Pulley, Aluminum w/ Black Pulley --- ## 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.co.th/products/3240565-acdelco-gold-38001-88909582-idler-pulley](https://www.desertcart.co.th/products/3240565-acdelco-gold-38001-88909582-idler-pulley) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-10*
