How can I get diagram and instruction manual for replacing the alternator belts(2)? No serpentine belt, I can't seem to find any diagrams that show 3 different belt sizes. 1 of those sizes is the 2 alternator belts. They travel around 3 pulleys, including the alternator. I hope that's not to confusing...Sry

I will attach the info below on how to replace the belts, but you basically loosen the adjusting nuts on the alternator and move it in to gain slack in the belt. Please see the attached document that will help with performing this. You are correct that you have three belts, and they are routed as shown below.

Please let us know what questions you have. Check out the images (below). Let us know if you need anything else. Thanks
