I began hearing a winning noise in my engine when accelerating. I was able to isolate the noise by placing a small hose to my ear and the other end placing it over different areas of the engine (like a stethoscope :D). This allows the noises on the engine to be singled out by their location and enhanced so you're able to hear them better. Once I found out I was at ease as this was a quick and easy fix... desertcart had this pulley in less than 2 days at my doorstep. The installation was very simple and a matter of minutes. This pulley arrived quickly and was able to install it without any issues. It currently works as if was OEM. I haven't heard the belt squeak when the engine compartment gets wet or when starting. It was a great upgrade. I recommend changing your belt as well when replacing a pulley or when reaching 70000 miles. I would recommend this pulley to anyone needing a replacement. I also replaced my belt when changing the pulley.

You just use the #14 bolt from the old Pulley and use the spacer screw on in the back and its a perfect fit. Hopefully its better than the original Steel Pulley. ## Frequently Bought Together - Dayco 89015 6-Groove Flanged Tensioner & Idler Pulley, 70MM Diameter x 28.3MM Width x 12MM Shaft - Dorman 419-5007 Accessory Drive Belt Idler Pulley Compatible with Select Models - Dayco 89372 Tensioner --- ## 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.us/products/11660180-dayco-89015-6-groove-flanged-tensioner-and-idler-pulley-70mm](https://www.desertcart.us/products/11660180-dayco-89015-6-groove-flanged-tensioner-and-idler-pulley-70mm) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-09*
