Replace the alternator in your Toyota Corolla 1.8 l and eliminate the squeal! 

For months now, my son has been complaining about a squealing noise when he started his 2010 Toyota Corolla. He took it to Toyota and they said the squeal was coming from the water pump. I changed the water pump but the squeal remained. My back yard mechanic diagnosis was that the bearing in the alternator was wearing out causing the squeal.
I was correct. In this video I will show you how to change out an alternator in a 2008-13 Toyota Corolla 1.8l.
