Fits 2007 Chevy Silverado 1500 5.3L
Changed both AC & Serpentine belts on my 2007 Chevy Silverado 1500 5.3L. Perfect fit, good quality! No noises, easy installation. Gates belts, ACDelco packaging.

This is the a/c belt only, the lower green not the main serpentine.
This is only the lower and not the main serpentine belt. The returns are mainly this being why. Also. The belt is a gates product. IMO superior to Delco products for this type of application. Gates is made in Canada and Mexico. Delco is hit or miss origin. Part numbers are the same for this HD belt between the two. Do not freak out it's a gates belt! Be happy. It's a better product. This is a green gates fleet runner HD belt. The best. 🤌

Fits well on AC drive of my truck, no squeals or slippage 5 moths so far. Lasted longer than the Main Serpentine belt of the same type and brand.

Simple install and nicely built and feels solid.
This literally took me ten minutes to replace. I have all tools needed so I didn’t struggle trying to figure out what was needed. A 15 millimeter socket and a 3/8 ratchet to relieve the tension on the belt to replace old belt. Easy project.
