on a 2000 v6 Astro you need to disconnect negative side to battery, remove the air filter housing by loosening the ring clamps to the throttle body, snap off cover, lift out air filter, pull entire unit up off pegs, then remove upper half of fan shroud, theres 7 bolts holding it and they're 10mm. Move top hose out of way before pulling up, it has a couple rubber things holding it it needsto clear. Then put the end of a socket extenion without a socket on it into the square hole below idler where belt is at your extreme left when facing engine, attach a ratchet to it and a bar for leverage and pull and belt will come off. Same thing when you put it back on. Change it if its been on a year or two. There are two bolts at bottom of alternator 13mm i think, and one on backside you'll have to remove the doghouse to get to. A couple of electrical connections back there also.
