HUGE PROBLEM--- Please Help--

Greetings to all,

    I am a first time poster here.  My wife has a 96 Grand Am, we have
had relatively few problems with it and it has been a great car for
us.  Today was another story.  While I was driving I stopped to make a
u turn, when I did the car stalled suddenly.  I restarted it with no
problem, however the power steering was gone and there was a red
battery indicator on the dashboard that was on. Realizing there was a
problem I began driving to a spot where I could safely stop the car.
While I was driving, which was no more than half a mile and a few
minutes I noticed the temp gauge climbing dangerously high. I stopped,
turned the car off and got out to find there was coolant leaking from
where appeared to be the overflow.  I also noticed that the belt that
p***** through the alternator was seriously loose, as in I could
remove it was little effort if I needed to.

  That is where we stand.

    I know that it not alot of info, but any ideas?

  Thank you to any and all who can reply.

  Jamie
