Post up a picture...not exactly sure what you're dealing with. Are you getting proper tension with just the right length belt?

 

subscribed...having the same issue.

 

Hard to tell from the angle but I had a similar setup on my old motor. I remember getting more belt wrap than that.

 

Actually its about the same wrap so maybe check pulley alignment since it looks like its not rubbing even... Here are some pics of the old setup

 

my pulleys are inline.
i do know the more i tighten the belt the less it squeals. but as stated above...i don't want to damage the alternator bearing.

 

What are the pulleys made from? What are the surfaces like?

What are the diameters as compared to stock?

 

Mine does the same thing. With the tensioner. Only squeals for a few seconds. Only on a COLD start. Stock pulleys, new belt, new idler, Was told it was because of my 130 amp alternator on a Vortech bracket...

 

Anybody with the squeak using a good year gator back belt?

I'm having the same issue at start up and feel it may be the generic autozone belt.

 

Gates Greenback here...

 

same problem

i have the march power steering and a/c delete kit, using the stock belt tensioner and it too squeals badly first starting and slightly just about every time after.

 

I have no issue at all, and never have had one, but I don't count. While I have a Vortech, I have stock pulleys and idler.

Glass or sand beading with a coarse mixture will really decrease slipping. I had some slipping issues on the SC, and I glass beaded my SC pulley.

 

Nevermind. It's late (for me). :king:

 

Just swapped to a good year gator-back. Squeal is gone.

 

If you don't mind please keep me posted on this.....I'd like to know if it keeps working. Thanks.

I'll chime in, had the same issue after removing smog and AC, using these aftermarket brackets. I ended up doing a different belt routing that is a little less stressful on the alt pulley. The belt is real tight, only get squeals in very cold starts, first rev.

I think it has to do with the angle of the belts from the pulleys. And with these brackets the more you tighten the tensioner it changes the orientation of the alt.

UPDATE:
This morning I swapped the BBK pulleys that were on the car to some steel underdrives I had sitting around. The billet pulleys were very slick and I think that is where the squeal was coming from. Anyway, it stopped for now. I may have just tightened the belt up a little more. I don't know. But no squeal!!!!

 

Goodyear Gatorback fixed my squeal...
