Weird Sound (Whirring noise) w/video

[Joseph.]

Hey guys was cruising on the highway tonight and upon getting off the exit ramp I started to hear this weird sound. Can't tell exactly where it is coming from, but I could even hear it inside the vehicle. At idle, the sound can barely be heard. Not sure if it's a belt, clutch fan/ rod knock, etc. Please let me know what you think!

The first check would be to see if the fan is rubbing on the shroud.

try removing each belt one at a time see if it goes away

could be alternator or maybe the cam belt tensioner?

Thanks for the replies. Turns out it was a bad water pump and the noise was from the belt. Changed the water pump out last week and everything is great! On a side note, my coolant light on the check panel has been on for the past year and I know there's no issues. Reservoir is full, system is bled, car is running properly and not overheating. I'm guessing it's the sensor. Which sensor is responsible for the check panel coolant light?

The one in the tank

The one in the tank

Is that the one that sits on top of the tank? If it's in the tank how do you replace it? Thanks
