Belt squeaking, why???

Belt squeaking, why???
Hi all,
I've got the 5.9 in my truck, and I cannot figure out why the belt is squeaking as much as it is. I can't even hear my exhaust anymore! I replaced the old belt which looked old and was cracked. I figured this would solve my problem. It still squeaks, very loud and constant, no matter what RPM! But if I spray the slightest bit of anything on the belt, it quiets down immediately until it dries again. I stuck a wrench on the tensioner and pulled it tighter while it was running and it did get a little quieter, but not much. I have a little play in my water pump pulley, but its barely anything. None of the other accessories have any play in them, nor do they turn roughly or anything like that. My fan clutch siezed up, so I'm not running a fan until next spring (its plenty cold enough up here) if that makes a difference. I did the whole wooden stick trick to all of the pulleys, and the tensioner was the loudest of them all. I have a new tensioner on the way and I'll be replacing that sometime this week. If its not the tensioner, I have no idea whats causing it. Anyone have any ideas?
Thanks in advance!

This is true! I had a prob. with the tensioner pulley and my regular auto parts store is closed on Sunday. So I went to Advance Auto with no choice . I have replaced my belt before and never once was asked about 6 or 7 grooves or any other BS .(but they asked at Advance which I thought was strange)I left with a 6 groove pulley and luckily noticed it before I put it on. They are selling universal BS , not what goes on your truck as in OEM. Sorry to SeaWalker if thats what you meant. And that was the nail in the coffin to never go to a parts store like that again. Even in an emergency it's not worth it.

Update
I installed the new tensioner assembly today..no change at all, still squeaking very loud! I also checked the belt and it is a 7-rib. I'm starting to wonder if the belt I bought is possibly too wide(?) I got it from Advance Auto, and its width is 63/64" (.984"). I checked at NAPA and their belt measures .947" wide. NAPAs belt is also a little over 1/2" longer. Looks like I'll have to pick up this belt and see if this solves my problem.
Also, the wooden stick thing..It probably has a better name, but it works like a stethoscope. I just used it to listen to all of the pulleys for weird noises.
