It is possible it a pulley but I would start buy jest puting a diferant belt on the car. I put 2 belt on my car this winter to fix a belt noise but I jest use auto parts store belts don't rembered where I got them but after changing it was good.
So the chirping is more than likely my radiator fan. The thing about my fans is that they're always on. Someone must have wired them to a relay located in the engine bay's fuse box that causes the fans to come on when the key is turned to ACC.
What is the reason why someone would do this? Can I make it so that the fans come on automatically vs on at all times? How about a switch to turn the fans on at will?
As for why they would have the fans ran that way is going to be either because they wanted to keep the motor(water temp) cooler and they did not want to send ECM off to have reprogrammed (if I rember right the 1993 ECM is diferant so you have to have a chip burned or programmed) or the fans wouldn't work so they jumped them.
