How do you replace the alternator on a 1998 Chevy S-10 2.2L?

Disconnect the battery then remove the fan shroud. Release the tension on the belt and pull it off the alternator pulley. I use a ratchet with a 3/8" drive inserted into the tensioner pulley for leverage, but I believe they have tool or pry bar for this. The alternator has three bolts keeping it attached, the two on the front are pretty easy to see and remove. On the back side of the alternator is a bracket attching it to the block. There is one bolt (don't remember what size) which is rough to get out. I was able to use a ratchet and deep socket to remove it. ONce I finally got it loose, I disconnected the wiring. Installation is the reverse!
