I have a 93 Lumina with the 3.1 in it and 176,000 miles. I went to go to the store today and it started squeeling bad and couldn't turn the wheel. Got the car back down the driveway and raised the hood. The pulley on the bottom of the engine seems to have come out a bit and caused the belt to slip off. I believe this is the pulley for the cam shaft, but am not completely sure. I can tap the pulley back on, but once I start the car again it comes right back off. I tried tightening the bolt that holds the pulley on, but the bolt doesn't move either way. Is this something that can be fixed? If so, how does one go about fixing it? Any help or suggestions would be greatly appreciated.
