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. Thanks
