Remove the serpentine belt by going clockwise with a 3/8 breaker bar on the belt tentioner UNDER the truck (I had to use my 1/2" breaker bar with a 3/8" adapter). Have someone remove the belt off the alternator as you remove tension under the truck (jack the truck up just a bit to fit) there is a square 3/8" for a socket ratchet to fit into on the tentioner underneath. Then remove the 2 - 13mm bolts on the alternator on top of the truck (under the hood). They are long bolts and rather tight, I loosened them with a breaker bar and then air ratcheted them out the rest of the way. Even with my cheap $20 air ratchet and $40 compressor, it does the job because there is not much room in there. Now pry the alternator loose with a BIG screwdriver, side by side until it's flopping around a bit. Then remove the 1/2" nut off the alternator wire and remove the wire. Now the fun part, getting it out of the engine compartment. It comes out BACK first, take the bolt to the wire out first and the entire black rear towards you (barely enough room). The pulley will be facing towards the engine and wiggle back and forth until it slides out. Good luck on the arm cuts! I didn't put my new one back in yet but I am sure it will be fun. Tom.
