Pretty much let u know what u needed to do in the very first reply you got.... if that was not enough... come on man.... i have not come across a manual on removing the alternator other than what is in the TSRM and if u need more help than that..... then everyone here is right and you probably shouldnt touch it.
You really only loosen two bolts. the one on the slide piece and the one on the mounting bracket after that the alternator will drop and u have more than enough slack to remove the belt....
