I would like to see pics too. Not sure what the OP used to host the pics but when photobucket stopped offering 3rd party hosting lots of DIY threads became useless.

I hate Photobucket. Harsh words I know, but what a move on their part! A few DIY threads I did on another automotive forum became, as you say, useless.

I fixed mine over the weekend. Just loosened both the top and bottom bolts, used a prybar wiith one hand and re-tightened with the other pulling it as hard I could and done.

No more squeaky belt.

Overtightening a serpentine belt destroys driven components and idler bearings.

Mine has been quite since.

As soon as I went to the Scion 100 amp alternator, mine has quit squealing. The Scion alternator uses a de-coupler pulley, so I think that has something to do with it.

Check out this 'interesting' video...

When I first got my car, it squealed badly, partially because the previous owner put belt dressing on it. I can confirm that delaying ignition does work, at least for belts that squeak when the engine is first started. It did on mine anyway.

The smooth side of the belt on mine was shiny probably from slipping. Increasing tension would not fix it. I took the belt out, lightly sanded it (probably 320 grit emory cloth) on the non-ribbed side to take the shine off, and also sanded the smooth pulley to clean it up. It's now completely totally silent for the first time in years.

mine hasn't squeek for yrs now. Just use a good quality belt and tighten it correctly, not too lose cause it'll squeal or not too tight cause it degrades it and wears out pre-mature.
