Good value on an accessory belt
New belt, works great and solved the problem with squeaks. I replaced the tensioner at the same time.

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. 🤌

easy install???
hahahaha... what is an easy install fan belt??? Chevy silverado does have a really cool belt system, pull a bunch of parts off then wind up the tensioner and sure it is easy to install. Belt is of good quality and was not and old stock item.

Fit my truck perfectly.
Had a crazy rattle when running my AC. Got under the truck and noticed the AC belt was chewed to shreds and the tensioner was worn plum out. After replacing both I have no issue. Fit a 2000 GMC Sierra 2500
