V10 belt squeal

I have a 2001 and my best friend has a 2005 both V10s. And at 2500-3000RPMs when pulling there is a high pitch squeal. Ive read a post or 2 about it being the belt, and to replace it with a Goodyear Gatorback belt. But can't find the threads now (I did search), found 1 but it's not one that I had read before. Anyway, wandering if anyone had the part number for the belt, and where to get it? I have tried NAPA and Oriellys here local and both say they can't get the Goodyear belts!!!! Lazy parts people I think.!! I did find them on Summit Racing, but they offer a 99.7" and a 100" belt. Which one? ANy help as always is greatly appreciated

Between 99.7" and 100" there's only 5/16" difference in length ,tensioner should be able
to take care of it?

Yes very true, BUT If the 100" is 1/8" too long it will allow it to slip just a little, Causing the squeal!!!! Where it may seem tight, but at 3000RPM it may slip a little due to being 1/8" too long. Follow me? But I have also put belts on that was supposed to be right, but you could barely get it over the pulley.

Before you replace the belt pull off the idler and tensioner pulleys and check the bearings. If you have the original bearings in them I'd bet they are shot or the grease is dryed up.

I've used the Dayco brand belt, it's a "cogged" style, just like the Goodyear, and it works just fine all the way up to 5000 RPMs and then the shift.

My stock belt at only 2 years old squeeled, switched to the Dayco, hasn't happened since.

+1 Mine was missing half the bearings when I finally replaced it. Definitely made a good bit of noise.

I think I even have a pic of it in my misc. gallery somewhere...

Found it:

I did replace my idler and tensioner pulleys already a long long time ago. They squeeked, even though they "felt" fine when spun by hand.

If you can get the bearing out and there is still a decent press fit for the new bearing you can replace just the bearing. If the bearing is good and it has seals you can pull a seal off and grease the bearing. Some tensioners have the plastic pulley molded over the bearing, (like explorers) you have to throw those away and buy a new one. I replaced just the bearing and regreased idler bearings before with good results, saves some cash.

I thought my idler pulley was bad. Sprayed some Windex on the belt and the squeal went away (Windex won't leave a residue on the belt). Replaced the belt with a Gates K081000 belt and it's been fine since.
