You didn't have to replace the whole tensioner assembly? I went after a new one bc the bearings are bad in it and they said I have to buy the whole assembly and not just a new pulley.

It was worth a try. Sorry. Good luck! Just went off roading in the snow here in NH and loved it. Happy Jeeping!

Majnoon You stick a 1/2 inch ratchet or breaker bar into the square on tension arm release pressure remove belt. Like dis.

curlysfries Thanks all. Will check pulleys as soon as I figure out how to take belt off.

harryhood Agree with those who say it sounds like an idler pulley. it's easy enough to check; pull the belt and remove the pulley, and spin the pulley on your finger. If the pulley does not spin smoothly it's bad.

Tys98tj Mine had a similar noise. I hadnt cleaned my engine bay in forever so I sprayed the mud off of the fan and it went away

Tomreb77 Idler. And change your belt while your at it. Easy to do, couple hours for someone like me a newbie. Good luck.

Xjman1 15 minute job and allies silent again. Once pulleys were off you could spin the old ones in your hand and feel as well as hear the grit in the old bearings.
I did have to go return the idler pulley and swap out for a Dorman unit as the first on would not seat properly.

CTX-Ross Did my water pump recently. Almost every pulley on the jeep is trashed... Idler, Tensioner, and A/C (water pump was about gone). They squeal and make the same noise. Idler is like $25 tops

TJ "Squealing" Noise from front fan area - Video

I have a 2002 Jeep wrangler x 4.0 112K miles, manual. When I start my engine I get this odd noise which I call "squealing" from the front area near the fan. I can't tell where its coming from or whats causing it. Jeep runs fine otherwise and it happens mainly when its cold outside.

Any assistance of what this might be would be greatly appreciated. Ive included a small link with video of engine and noise.

Thanks
