Good luck nitro I've had the same problem. I've changed tensioner pulley no help. When i put on a new belt it will stop for a while but slowly returns. I even put extra pressure on the belt while running to see if it would make a difference but it made no difference. Temp and moisture made it squeak also until it warmed up. but eventully it does not stop. This all started when I thought my OEM belt looked a little dry rotted and cracked so I decided to change it with another OEM belt. No squeak before then but it's been a nightmare since. My water pump did go out I changed it and installed a new belt. Now it squeaks only when it's cold or it's been raining it will squeak at start up until it dries or warms up. Good luck hope you find a cure let us all know. I will clean my pulleys with brake cleaner and try that. ltl you put brake cleaner on your belt also???

My belt makes noise depending on the temp. I removed the idlers, pressed out the bearings, removed the seals, cleaned, dried and regreased, reinstalled the seals, pressed back in. Same noise. I installed new idlers. Still same noise. I checked everything over and couls not find anything else wrong. It does go away when it dries out and warms up. I did notice that mine squeaks when the writing on the belt goes by the tensioner. Thought it was weird but I guess yours does it also. So must be the belt.

That is what I noticed on my truck. I know it sounds weird. I didn't say anything about it cause it seemed so weird. So I just left it alone. It only does it on occasion and only for a little bit if it does.

I replaced every pensioners and pulley on mine for 2 years before finding out it was the harmonic balancer. The rubber had hardened and worn on the damper ring causing it to hit the water pump pulley cockeyed thus causing a permanent squeal that took 2 years to find. Been quiet for almost a year now. Went thru countless belts tho, found the oreilly or napa hd belts to be the best, imo. Hope this helps

A little update: I took everyone's advice and looked into a bunch of things. It seemed the culprit was it being a new belt and the writing on the belt was squeaking on one pulley. I took some of the writing off and the problem seems to have gone away. Next step is a new tensioner and belt if it starts up again...
