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

Great HD replacement belt

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. 🤌
