theres a loud schreech that comes from my car when i start it and when I am driving it will schreech randomly. I was thinking it was my water pump, but I I had it replaced about 30,000 miles ago shouldn't it last alot longer then that.

Any input would be appreciated thanks.

 

loose belt; either AC/alternator or PS

 

Can you describe the sound more? Is it more like metal on metal scratching or a whining/squealing sound? If yours sounds anything like mine, it could be the throwout bearing.

 

Mine does the same thing. My ac belt needs replacing. Crank your car up with your AC off, and then turn it on while running. If the "screeching" sound is activated by that, then that's your problem.

 

Ya after I messed around with it a little, it turned out to be slippage in my belts lol. I just sprayed conditioning on it and it fixed the problem.
