I have replaced the serpentine belt, the tension pulley, idler pulley, and checked all the other pulley's (good). Trying to see what else could be squeaking when I accelerate up to 2,000 RPMs or more. The transmission maybe?

Good afternoon,

Does it sound like a power steering noise?

Can you upload a video of the noise so I can hear it?

Okay, got it.

I would remove the belt and spin the pulleys for the alternator, power steering pump and water pump and see if they make any noise.

It sounds like a water pump bearing. Check the idler pulleys as well that I circled.

Thanks so much for your expertise. I spun all the pulleys Friday and only one was squeaking (the tension pulley). I replace the tension pulley idle pulley and the belt. But I will do it again.

What's a good way to check it? Spin it very hard? Thanks again I greatly appreciate it.

Spin it with your hand. Check for any play as well in the bearing.

Does not have to hard at all.
