I dont think I can see it

 

See the small belt around the compressor. You can remove the larger belt then from underneath remove the smaller AC belt. Spin the pulleys by hand to see if you can hear a bad on. If you can not find it that way. Start the engine with no belts for a few seconds to see if the noise is there. Then put the AC belt back on, run it for a few seconds to see if the noise is back. If the noise is not there for either test then you know its not engine or AC.

 

Wow thanks for the detailed description!! Will be trying this

 

Don't run the engine long there is no water circulating in it. 20-30 seconds tops.

 

OK so i replaced the idler pulley, and serp belt and yet it still makes that noise. I couldn't see the AC belt.
Im not sure if it's the tensioner pulley or something else

 

So my guess is either the tensioner pulley or the AC clutch thats going off

 

i thought you replaced the tensioner and pulley

 

I did not have the proper tools to remove the tensioner, I only replaced the idler pulley sorry for the misunderstanding

 

you have two tensioners. one for a/c and one for everything else. so you say the belt for the a/c pump is gone

 

sorry... yes I think its either one of the two
