Weird knocking noise coming from pulley(s) area

[mikethemike]

Hey guys,

Long time no posty-post. Cars running fine, has about 61k miles and recently just did a tune up which involved putting a new serpentine belt (the old belt was baaaad). But since its been on, this noise, sounds like a faint knocking, has been popping up while idling (and reversing). I mean its probably there throughout the whole time while driving but i wouldnt be able to hear it.

Any similar experiences? I'll post a video. Stay tuned.

im not a expert by any means but to me it sounds like the belt either isnt on correctly or needs to be adjusted.

Thats what I thought too. I inspected the belt. ITs on there, nothing seems to be off. I got the belt on there fairly easy with a friend which for a first time, that made me wonder if its too good to be true. But its been about two months, no problem other than this noise.
