Hi, does anybody else's belt tensioner push down? in the diagram the belt is on the bottom of the tensioner which means the tensioner doesn't do anything and the replacement belt is too big. Is it correct to loop the belt over the tensioner so it will pull the tensioner down thus create tension? Could the diagram be wrong or is the tensioner on backwords maybe??? I bought the belt at autozone so maybe wrong belt? HELP PLEASE

Yup…
Sorry just wanted to share, tossed my belt about two weeks ago. I have a smog pump delete and had no idea what belt I should use to replace with no identifying markings on the belt that got tossed. Turns out this smog delete allows you to use the oe belt ~92.3”. With the breaker bar attached to the tensioner seem to recall cranking it towards the air inlet duct btw mines is a ‘90.
Routed as such...

Seems like we loss the OP...
Yup the bearing on the pulley seized up and the heat generated melted the plastic pulley. I ended up borrowing a pulley from another serpentine setup that I had laying in the parts bin. Local store wanted $40 and some change for the replacement part when rockauto had it listed for a fraction of that. Curious question, my original to me on the vehicle had a flanged pulley. The one I sourced locally and happily returned was smooth. We all get caught up with more is bettah, comments on a flanged vs. smooth pulley. My thinking is the flanged pulley would have less likelyhood of being tossed during spirited driving.
