Review: Very smooth, very quiet operation, just like factory - I will only buy GM original parts or ACDelco for my 2005 Z71 crewcab. I’ve been down the fraction of the price, can’t pronounce the name parts from desertcart and will not go down that road ever again. OEM is the only way to go. Especially on a part like this that is constantly moving and needs to last 60,000 to 120,000 miles. My previous one (OEM) was on there 116,000 miles. I’ll take that again. So I’ll pay the extra and not repeat this and have to buy another one in a few thousand miles. ACDelco Gold is the ticket. This thing fit perfectly, and zero noise. Smooth as glass operation. My old one was rubbing on the tensioner arm, making a scraping sound.. wore out. The new one looks purty under there. And works great. Always buy OEM, GM original parts or ACDelco only. You won’t be sorry, but trust me. Review: Fits like OEM - Feels and looks like OEM. This item was a breeze to install and had a much smoother operation than my old one that i had been neglecting to change. It gives the engine a cleaner look and eliminated the slight squeal that the old one was starting to make. ## Features - Designed to keep drive belt at proper tension - 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 | B000C9PFJK | | Belt Style | serpentine belt | | Best Sellers Rank | #8,599 in Automotive ( See Top 100 in Automotive ) #2 in Automotive Replacement Belt Tensioners | | Brand | ACDelco | | Brand Name | ACDelco | | Color | Aluminum w/ Black Pulley | | Compatible Devices | Vehicles | | Customer Reviews | 4.6 out of 5 stars 2,592 Reviews | | Global Trade Identification Number | 00021625584454 | | Included Components | Drive Belt Tensioner | | Item Type Name | Drive Belt Tensioner | | Item Weight | 16 ounces | | Manufacturer | ACDelco | | Material | Aluminum | | Material Type | Aluminum | | Number of Items | 1 | | Part Number | 88929140 | | Style Number | 38158 | | UPC | 021625584454 | | Unit Count | 1 Count | | Warranty Description | Limited Lifetime Warranty (Parts Only).

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 ### ⭐⭐⭐⭐⭐ Very smooth, very quiet operation, just like factory *by S***R on May 28, 2026* I will only buy GM original parts or ACDelco for my 2005 Z71 crewcab.
