I think i can pull that baby out in about 15 minutes because i had issues with it before and had to have it tested. The bottom of the alternator sits on a long threaded stud, so you need to pull it forward to clear it. unfortunatly, the rad fans get in the way so you have to remove the 6 10mm bolts for the fan assembly and push the fan assembly up alittle while freeing the alt from the mounting stud. I was able to wiggle the fan assembly enough to clear the pulley, then dropped it down, moving the lower coolant hose over by hand so it can squeaze thrue to clear. I made the mistake of cutting one of fan cover fins the first time because i could not get it to clear and was in a hurry(didn't loosen the fan shroud). since then, i epoxied the fin back on and was able to get the alt to clear the stud the second/third times after, just be moving the fan shroud around, and swinging the alternator around(while on stud)to clear.
May i ask, what is wrong with your alt?
Here's also the FSM method, which is alittle different and not very descriptive(need to remove a bracket, which i did not see).
