Horrible serpentine squeal after alt. relocation.

I am finishing up a turbo build and have moved the alt to the upper pass. side. When I measured for a new serpentine belt I just cut the old one and measured to 69". While running the motor has a horrible squeal. I have sprayed the belt with water to see if something is out of alignment which doesn't really help. Just noticed the tensioner is bottomed out so I need a smaller belt, but the current belt seems close, not slipping just howling (added tension makes noise go away). How much smaller should I go? 68.5" 68"? If anyone has advice I would like to hear it. I don't want to go so small that it will be a bear to get on. Thanks, Alex

try using a piece of string , run it like a belt and that will give you what you need.

Are you sure that the belt is aligned?

That is the key. If its not aligned then it will make a ton of noise and shred the belt pretty quickly

I'll second that. Relocated alternator to top passenger side and belt tensioner to top drivers side. My tensioner is about maxed out like you said and my belt was squealing like crazy.

I measured and the tensioner needed to come out more. Put two washers for each bolt behind the bracket and no more squealing belt

Belts gotta be tight. If tensioner is bottomed out like out to its most loose point get an inch shorter belt. That should get it tight enough. Run into that at work sometimes with Chevy SUVs that have different amp alternators and stuff. May not feel the difference but when you put load on belt like really cranking on steering wheel or something it screams.
