Lots of great advice here. These guys have it covered.
I did a huge project with my TB/WP change a couple years ago. I swapped to a police alternator, ASP crank underdrive pulley, Alternator OD pulley, and new belts. I didn't do my Tstat because mine isn't all that old, I changed it a few years back and it's got plenty of life left. I wish I had known about the method of removing the alt to get in there from the top, working in a driveway from the bottom sucks.
