I would like to share some tips from my experience. The serpentine belt (alternator belt) has one adjusting bolt, which is a Torx T60 bit, which is spring loaded-eventually the easiest of the two belts. The AC belt has two adjusting bolts as pic's here on this site has noted and describe them as bolts #1 and #2. Bolt #1 was I believe a Torx T45 and reached from the top of the vehicle, and bolt #2 underneath the vehicle is a Torx T40. This AC bolt #2, underneath the vehicle is the PITA working in very tight space. There was enough room underneath for me move the pulley with a finger tip towards the front of the vehicle using one hand to clear a very small amount of space, and the other hand to ease the extension up towards the bolt head.(Of course bold #1 on the AC should already be loose to get this small amount of movement), I was able I to increase my chances of a clearer pathway to get my 3/8 universal and extension at the bolt the head #2. It was still a "very-very" tight space and it took many exhausting attempts getting enough revolutions on bolt #2 to eventually tighten up the AC belt. I hope this little bit of suggested information helps some one.

glad you got it replaced. It was definitely a PITA. Not hard, but frustrating having to work in such a tight spot.
