Need help w/ Belt Tensioner

My belts have been squeking really badly on start up since I bought the car, the past couple of days it has been doing it close to non-stop. I looked at the tensioner and it was all the way too the loose side. I decided to by-pass the smog filter while im at it...........

I picked up a 85" belt today and will be picking up the 84.5" belt tomorrow (I had to order it). I went ahead and installed the 85" just to see if it would work. It works but the tension is still really really close to the all the way loose range, and Id like it to be more in the middle b/c I figure the belt will stretch a little bit.

Now, the problem is that I had a really hard time forcing t5he tensioner down to get the 85" belt on, I pushed on it by hand until it went on and it took all my strength and leverage. I have NO IDEA how to get the 84.5" belt on. I have a Chiltons manual but all its says to do is put the belt on, no specifics, othe then dont pry on it. How the heck am I supposed to get that belt on there????

Oh ok, so I put the wrench on the bolt that is attatched to the actual pulley, not the bolt that you break to get it to loosen up? Also know as the bolt that would be in the right part of the pic

^^^So take that bolt all the way out. Put a breaker bar into the now empty hole and lift it until the tensioner pops into place. Then put the bolt in and tighten it down??

^^^ Just wanted to say thanks and you were right, it was super easy that way!! I put the 84.5" belt on 2day and all is well. I feel like such a boob not doin that way from the start
