Easy fix for Squeaky / Squealing Belt

I've never posted here before but thought this might be of help for some of you. I have almost 90k miles on my wife's Yaris and since about 50k miles, the belt squeaks every now and then. I decided to tighten it myself and to my surprise there is no tensioner. You are just supposed to pry on it while tightening. After doing so, it was not much better. So I brought it to my local Toyota dealership and had them put a new one on thinking they would be able to do it right since this is the first time I've seen a belt without a tensioner. I picked up the car and the brand new belt squealed worse than it ever did before. So I went home and made my own tensioner. Here are a few pictures of what I did. I just got some angle iron and cut 2 pieces about 1.5" long each and drilled two holes in each. Put a couple bolts in and made my own tensioner. No more squealing. Angle iron can be picked up at Home Depot or Lowe's for a couple bucks. You just tighten down the two bolts on the alternator slider and have the two pieces about 1" apart. Then put a bolt through the two L brackets and start tightening. You can put washers in between them if you want to space them out further and not tension the belt as much. Don't over tighten, but this is a sure fire way to not have it squeak anymore.
