check all your other pullies to make sure they are not seezed up. like your water pump power steering even your emmision pump if you still have it.

I'll bet that you didn't get the belt tight enough. Loosen off the pivot bolt on the bracket, slide a prybar in the bracket hole and push HARD against the alternator. Now tighten the pivot bolt back up. Sometimes with a new belt it helps to get a buddy to help you.

I would also take close at your alternator pulley. Make sure it turns freely and doesn't make any grinding or whining sounds when you spin it by hand. Maybe the reason you lost your first belt is because your alternator pulley is losing it's bearings and getting hot after a while.......

actually I think I need a new alternator becuase the pulley is warped(mabe its the shaft or somthen else) is there a way to repair this or just get a new one?

SO when you spin the pulley does it wobble around? It could be a lot of different things, but if it's the pully itself and not the shaft you may be able to unbolt the pulley and buy a new one. I guess the solution to your problem depends on how your alternator is built.
