Fan belt squealing

[Roysbigtoys]

Well here is an update. I cleaned all the pulleys and checked to see that they all turned freely. Taking Mr Hagg's advise, I ordered a Gatorback belt. After waiting several days for " over night shipping" from Summit Racing, I canceled my order. I then found the belt on Amazon for a better price and free shipping....."thanks" to my wife for being such a frequent shopper. In the mean time I changed the harmonic balancer and the bottom pulley, put the slightly used oem belt on ( at this point I did not have the new Gatorback belt ) and the squealing stopped.
The pulley did not look worn, but apparently it was enough to slip. I haven't put the new belt on yet, but it looks like a beast and had really good reviews. I will probably run the oem for a while then put the new one on.
Thank you Rawze for this site and for everyone who contributes to it.
