2014 Jeep Grand Cherokee 5.7 Engine Bay Croaking Noise...

I recently just started hearing a croaking noise coming from the engine bay, similar to the sound of a bullfrog... It's loud enough that I can hear it in the cabin of the Jeep.

I have no idea what it could be, I sprayed the serpentine belt down with WD40, I don't think that is the problem.

Any clue?

I made a video (to capture the audio), you can hear it here:

Quite regular rhythm on the recording. Does it change in loudness or anything if you vary the rpm?

Serpentines usually squeal if they are loose, and I wouldn't put wd-40 on one unless I knew in advance it wouldn't soften it. Unless it is really really loose enough to vibrate.

It almost sounds like exhaust noise.. or a really big bullfrog.

Water pump replaced, the Jeep is as quiet as I've ever heard it.
