Serpentine Belts

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.
