Replaced all 3 belts on my 2015 GMC Sierra 5.3l along with a new tensioner. Is a new tensioner necessary? Probably not at ~87kmi but it’s one of those things where while you’re already in there, and it’s easy and cheap to do, just do it. Review: Good GM Part Good Price - Good GM Part, great price discounted for packaging damage, went on easy, quieted front of motor down with this and new serpentine. Went on my 2015 Silverado 1500 5.3 all stock with 130K miles on the original parts. All good 👍👍! ## Features - Helps keep drive belt at correct tension to help maintain proper function - Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE) - GM Genuine Parts are designed, engineered and tested to rigorous standards, and are backed by General Motors. - GM Engineers design and validate OE parts specifically for your Chevrolet, Buick, GMC, or Cadillac vehicle - GM regularly updates production and service part designs to integrate new materials and technologies ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01M1B18MY | | Belt Style | serpentine | | Best Sellers Rank | #99,311 in Automotive ( See Top 100 in Automotive ) #73 in Automotive Replacement Belt Tensioners | | Brand | GM GENUINE PARTS | | Brand Name | GM GENUINE PARTS | | Color | Black | | Compatible Devices | General Motors vehicles | | Customer Reviews | 4.8 out of 5 stars 229 Reviews | | Global Trade Identification Number | 00808709557715 | | Included Components | Auto part | | Item Type Name | Drive Belt Tensioner Assembly | | Item Weight | 2.1 pounds | | Manufacturer | ACDelco | | Material | Rubber | | Material Type | Rubber | | Number of Items | 1 | | Part Number | 12670574 | | Style Number | 12670574 | | UPC | 808709557715 | | Unit Count | 1 Count | | Warranty Description | 24 Month / Unlimited Mile Limited Warranty on parts sold on or after 04/01/18.
