belt squeel driving me nuts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have the serpentine belt set on my 69 C10, it started out nice and quiet now it sounds like two cats killing each outher when I start it, I thought it was too tight so I loosed up the belts and it worse, they feel tight to me like I would adjust a single v-belt but squeel, I hate to use belt dressing that styuff is a mess on my new engine. Sould I tighten then up a bit more or could it be something else causing the squeel, I also can decide if its comming form the alt ot PS pump side.

It appears to be lined up correctly, its the two belt system with no tensioner pulley from JIGS.

So it looks like the alt billet mounting bracket and bolt bolt on the top it just a mm or 2 longer throwing the belt off just a tad, so I am going to remove it and shave it down to see if thats a fix or not.
