Belt Tensioner Prob
For some reason my belt seems to keep slipping off of the tensioner. The belt will come half way off and then excrete a loud whistle. Its actually popped completely off a couple times and I've had to perform open heart surgery on the side of the road. What is casuing this?
For reference: 6.0...Radix...3"....and the belt that came with the 3.4" pulley for the ol 5.3

What length belt are you using? I think with a 3.4" you should be running a 112" belt. You now have a 3.0" so you prob need to shorten that up. I have a 111.5" belt on my 3.2" pulley. Engine doesn't matter, they all have the same pulley geometry. Just be happy your not snapping tensioners. I have broken 2 in the last 2 weeks.

I bet you need a 111.0" or 110.5" to keep it from walking off. Just dont go too tight or your alternator bearing will give out...pain in the *** huh?

Mine does it on a WOT run. I nail it and when I let off I lose power steering. It happened once as soon as I stomped it the other time I went from 45mph to about 85mph and when I let off, no power steering. The tensioner broke both times. Could a belt that is too tight cause this? I have the tensioner almost maxed out so when the belt comes off the tensioner travels all the way back to the stop and SNAP!
