Noises problem
1995 Chevy Astro Automatic

what is the name of the component in the top right position of the serpentine belt path? There is a knocking noise that accelerates and gets louder as I accelerate and it sounds like it might come from this component. At idle it is more of a muffled knocking.

Here is a picture of the belt layout and parts list.

Are you sure it is from there and not from the engine? You can check by removing the belt to see if the sound is still there. NOTE: If you remove the belt to check, do not run the engine longer than 8 to 10 seconds.
