There are 3 bolts to get the alternator out. One on the top and two on the bottom. Remove the first bolt that is on the top of the alternator. Use a ratchet with an extension socket to get at the second bolt directly underneath the alternator. This bolt is actually attached to the slider to tighten and loosen the alternator into place. After these two bolts are out loosen the bolt at the bottom that is more towards the front of the alternator. It's a tight place to be working the ratchet but you'll get it.
