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.

Identical to the original. ## 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 | #54,689 in Automotive ( See Top 100 in Automotive ) #30 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 224 Reviews | | Global Trade Identification Number | 00808709557715 | | Included Components | Auto part | | Item Type Name | Drive Belt Tensioner Assembly | | Item Weight | 2.14 Pounds | | Manufacturer | ACDelco | | Material | Rubber | | Material Type | Rubber | | Part Number | 12670574 | | Style Number | 12670574 | | UPC | 808709557715 | | Unit Count | 1.0 Count | | Warranty Description | 24 Month / Unlimited Mile Limited Warranty on parts sold on or after 04/01/18.
