Try tightening the mounting bolt on the idler and/or tensioning pullies. This did the trick for a persistent squeek on my 93' Jeep Wrangler.

On some cars, the idler pulley {usually on the belt tensioner) can squeal. If you squirt some WD-40 or similar lubricant on the front of the bearing (engine off), and the noise goes away, it is probably the bearings in the idler pulley. If this is the case, replace the idler pulley, because the noise will come back after the lubricant gets slung out of the bearing.

I also have a Plymouth Laser, I had the same problem and tryed the same things. If the above answers don't seem to work, look at the water pump. In the water pump there are ball bearings the keep it spinning smoothly and when the casing of the bearings give way, the bearings no longer glide over the surface, instead they bunch up and rub against the back of the pulley. If this is the case, you will be able to see the bearings behind the pulley.

How do you adjust the alternator belt in a 1997 Honda Accord to make it stop squealing even when it seems to be tight enough?

Because the alternator puts a load on the engine of several horsepower, the belt must be very tight. However, if it is too tight, the bearings of the alternator shaft will wear out quickly. To tension the belt properly, adjust until there is about 1/2 inch of play in the center of the longest span. If this does not stop the squealing, the belt may have been glazed from being too loose, and needs to be replaced.
