the old belt looked or I think it was a pollygrip by delco. I just bought a gator back and I am going to install it asap.

 

Like ironstone, check the idler pulley, it should be tight. If you even suspect it change it cause its about to go.

 

I can not move the idler by hand it is very tight

 

I Just greased the bearing on my idler pulley yesterday. This is my 2nd Dodge CTD and I have had to do this routinely on both. On both trucks it squeals badly in the spring. I think it has something to do with the humidity and warmer temps.

Pull the idler off get, a T50 torx and pull the pulley off the idler. Take a pick and gently remove the seals without piercing them, pack with some good grease, reseal, reassemble, repeat as needed. Or you can buy a new idler pulley for more then $100-150. I'm too cheap I just lube the old one as needed.

I'd like to replace the bearing on the pulley but I don't think it can be removed without damaging the pulley. It looks like some kind of composite material or pot metal or something.

 

good tip i will try it

 

Heykw - I'll put my money on tensioner idle pully is worn and running belt a few thousands of an inch ouit of align. Believe autozone has pully for around 70 dollars or so.

 

Would "razorbak" actually be "Gatorback", the one Goodyear sells? That's a popular belt because it is less prone to make noise.

 

Check one more thing. check the bearing that the fan rides on. I had one go bad. Remove the belt and spin it see if it is free.

 

I put a new tensioner and gator back belt on and the noise is gone I noticed the new tensioner does not move as much as the old one did.

 

yeah, thats what it is, i got my belts confused with my broadheads. at least both things are in the b category.
