First off..the smog pump is removed (dont need it in central WI).
Second... when i would turn on the HVAC system, it would squeel. Turned it off... no problem. Well winter is coming up and heat is a must.
This weekend my goal was to fix the squeeling issue. I went to Autozone and got a new belt (Dayco 5060930/ 6PK2360), put it on, and now the sqeeling is much worse, even with the HVAC off.
I checked the tensioner with a 15mm socket before i installed the new belt and it seemed fine to me. The only issue that i see is that, when i try to turn the belt, i get about 1/2 to 3/4 turn on it now.
Does anyone know what could be causing this to happen? wrong size belt? bad tensioner? Im at a loss here...

Automatic tensioner by the way
