Tensioner? Can anyone put any insight? I think its possibly the belt because spilled some ps fluid on it while changing the Reservoir.. Also does anyone have the part # for the belt

Heres the video

 

Anyone?

 

Definitely sounds like a pulley bearing going out on you, but difficult to tell which one without being there to diagnose it. If you have a long-handled screw driver, carefully place it on the stationary bolts on the idler and tensioner pullies and use it as a stethoscope. Listen to determine if the noise is coming from either of those two. Otherwise, the best thing to do is to remove the serpentine belt and turn each of the pullies to feel for bad bearings or excessive resistance. You can also start the engine for a brief period of time with the belt removed to rule out any of the pullies from the timing belt area. If the noise goes away with the belt removed, then you've narrowed it down to one of the accessory/tensioner/idler pulley bearings.

Edit: Btw, belt part number is:
Part Number: 38920-RCA-A03 (3.2L or 3.5L engine)
