Strange noise idling, revving engine, and driving
Higher speeds like 30+ the sound is mostly gone. As you accelerate to 10+ the noise gets quieter. Even with windows down. I had a/c and heat off, and still made noise. Not sure what the noise could be.
Here is a video. Sorry about the beginning. Didn't realise the camera was blocked.

Power steering fluid was at the min level when the engine was warm. So I added some. I loosened the belt, and moved the pulleys. They seemed fine.
Found another test i'll try tomorrow. It sounds like it could be the alternator bearings.

Sound is gone now. How long do the water pumps typically last? I think I am on the original at 110,000 miles. Also what part number? I only found some for the timing. Not the serpentine belt. Just so I have a part reference for future.
