hey sometimes when i go to start my car.. IT makes this really LOUD shreiking noise....and i dont know why...... what i do is just turn it off... take my foot off clutch and then back on.. and it starts?

waht could be the problem?

 

First thought is your alternator belt is slipping, try tighten it up it shouldn't move more than half an inch maximum when you press it firmly, in the middle of it's span.
