Help! Belt Noise

[Sbteke128]

Can someone help me diagnose this problem. I know its not the serpentine belt because its about 5k old.

Could it be the tensioner going bad?? Just a guess

The cheapest parts to replace are the idler and tensioner pulley. I just replaced mine at 210k miles. If that doesn't fix it then check your water pump and AC.

thanks for the response.. i will check up on the idler and tension pulley and see if that solves the problem

Replace the tensioner and idler pulleys anyways. I recently ignored my new found noise only to have the idler pulley sieze on me on the highway. Popped the serpentine and literally welded aluminum dust and shavings onto the bearing race and shaft. Took a little dremmel work and a bit of tapping with a brass drift and hammer but I was able to get her fixed in the parking lot at work.
Dont be me.

Mine made the same noise just spray wd40 in the bearing/ were the bolt holds it on and noise went away for me
