Serpentine belt squeaking Sign In

Alternator light came on last night. Took a chance and drove the car home with it on (for about 20 minutes). Found the serpentine belt shredded this morning. Got a mechanic to come change it and now it's squealing loudly. Squeal goes away with water for a few seconds. The mechanic says the alternator is getting really hot and that the alternator may need changing. Could it be that the alternator is overworking to recharge the battery? The alignment looks good and I hope the tension is good as well. The mechanic said the tension is good. Is it safe to drive the car with it squealing like that?

The belt didn't shred on it's own. Something is freezing up and you need to find it or you will be going through the same thing again. Remove the belt and spin each pulley by hand and see which one feels rough. Good chance it is the alternator. It should be obvious if you use a stethoscope.
