Something that gets neglected on General Motors GMT 900, 2007-2014 trucks is the air conditioner belt. It’s buried deep between the crank and passenger side mounted AC compressor. Mine was totally cracked up and had 210,000 miles on the original. I ordered a belt and tensioner kit from Rock Auto. You can get to it by removing the air inlet tube and top half of the fan shroud, or you can remove the plastic “ skid plate” and come in from the bottom. I already had the stuff removed from the top so I came in from above. Here are some shots of the cracked belt, the new and old tensioner, and a shot of the new Gates belt and the tensioner I installed. This is boring to any pro mechanic but might be interesting to fellow Weekend Warriors. Enjoy.
