Question about Toyota Yaris
I just removed the alternator from my 2008 Yaris. The belt was squealing and thought I could put a little more tension on the belt by adjusting the alternator. I actually found the bottom mount bolt loose. I put about a 1/4 turn on it but it still wobbled. I took the bolt out and the mount hole seems elongated as is the hole on the alternator. Is this normal? If not how is it fixed.

That should be right if it is an idler pulley. On belts that do not have idler pulley you will have to loosen lock bolt on adjuster. Like alternator

I have not seen this vehicle but, the center bolt or nut that holds the tensioner to the block is backed off two turns first.
Then the adustment bolt (most are accesed from under the vehicle) can be adjusted to give enough slack to install the new belt.
If this is still too tight, remove one of the two or two of the three bolts that mount the Alternator to allow for another 1/8" and install the belt.
Then remount the Alternator.
Then readjust the tension bolt.
Finish with the bolt or nut that mounts the tensionor to the block.
