Ok, what am I missing to adjust the a/c V belt? Loosened all I could see and I see more slot....I'm gonna get a big stick in a minute!

Looking for how many bolts to loosen and where should I be prying from? (1992 E350) gotta run the defrost and thats making the AC turn on and slapping the fan

 

Did you get to the small 3/8'' bolts on the backside bracket?? I use a 1/2'' breaker bar in the square slot to adjust it.

 

What? Bolts on the backside? Where? Dark out now but when the sun comes up.....I'm gonna throw down on this beast!
