ok, after having put my old belt back on, the belt is on all the grooves on all the pulleys except for the crank pulley. it is off by one groove. any opinions. i went and returned the belt to advance, and stepped it up a notch and got a dayco instead. should i replace the tensioner? this is an all-of-a-sudden thing. ive gone almost 10k since i replaced my p/s pump and this is the first that anything has happened with any belt.

It shouldn't do that at all. When you put it on, make sure it is on all the pulleys nicely before you release the tensioner.
How does your tensioner feel? Is it nice and stiff, but, springy? (yeah, that sounded good......) if it feels sticky at all, replace it.

the tensioner feels ok, kinda hard to relieve pressure, but i think thats how its supposed to be isnt it?

I assume you cleaned the grooves in all the pulleys? Get the Dayco tensioner. I use Gates belts and never had a problem with squealing, so I don't know what the big deal is , to tell you the truth.

You have the wrong underdrive pulley on there for your model of truck.
Six groove underdrive pulley on a seven groove belt or vice versa.
That's why you are throwing the belt.
If the underdrive pulley is six groove, you can run a six rib belt on all the pulleys, but be sure to set it in the grooves closest to the block, meaning that the last groove nearest the radiator will be bare on all your pulleys, save the crank.
Reverse that if the crank is seven and the others are six, leave the last groove in the crank pulley bare.

That direction is not an issue, it's if it's free enough to apply tension in the opposite direction.
ok, so new update. installed my new dayco belt, and low and behold the belts jumps a rib ONLY on the crank pulley. could it be a bad tensioner, or idler, or what? this has me so stumped..... i need to get this new belt on!
