belt? alternator? pls reply because it's anoying !!!!! is that I can fix
for myself or have to bring it in?? and if i bring it in, have any idea
what would be the cost ????

It's probably a fan belt slipping. Check the tension on the belts when the
engine is cold and let us know which of the belts has the least amount of
tension on it. You may be able to solve the problem by visiting a auto
store such as NAPA and buying a spray product that might be named "belt
dressing" or "belt spray". You could spray it on the belt that is slipping
and it should make the screeching sound go away. Another way to identify
the slipping belt is to raise the hood and watch the belts as someone else
starts the car. Make sure that you don't touch anything under the hood
while the engine
is running. Let us know which of the belts is slipping if the belt spray
does not solve the problem.

Worn/loose accessory drive belt;fairly easy to replace yourself.
Not very expensive to have someone replace it for you.

I agree with the other posters that a slipping belt is likely the
problem. A distant second hypothesis might be a hung up starter
solenoid. It makes a distinctly different sound that still might be
called a screech.

The explanation of why the belt stops screeching after a short time
(if that is what it is) is that as rubber warms up, it shrinks. (Most
substances expand when heated. Rubber shrinks).

I would not advise using belt dressing unless it is an emergency
situation. Get the belt properly tensioned or replaced.
