    Ringing @ 4500+ RPM... Water Pump?

    Like the title says, I'm getting a ringing at 4500+ RPM. My internet searches suggest it's either a belt problem or a water pump problem. I sprayed some belt dressing on the serpentine just because it was the cheapest thing to try. It didn't work. I'm not leaking coolant that I can tell and I am not seeing any unusual running temperatures. I have been driving it daily waiting for something to pop on me but it drives great like there's nothing wrong. Is there something I can do to check the water pump before I go and buy a replacement?

    Is it a ringing like from under the hood or is it a ringing like over the speakers and you're expecting something to pop up on the DIC?

    I'm not sure if I'm remembering correctly, but I seem to remember reading about somebody with a similar concern when their car was new and a GM engineer determined that the ringing was caused by the coolant's passing through the cooling system that just happened to reach an audible harmonic at a certain engine speed. I think there was some solution, but I don't remember what it was or if the car was even a CTS-V....so I guess I'm not helping, lol....I'll go back to my cubby now...

    My car has 99989 miles when I left it in the garage tonight. This JUST started a few days ago. About a month, ago my car developed a nose on my way to work that I determined to be the alternator during the day's research. I priced a new one and scheduled time to fix it. When I got out to my car after work, it was fine and I haven't had the problem since. It was a very loud noise that increased with speed. There was a video of the noise that was identical posted in some thread. But this is a ringing that kicks in and stays consistent from 4500 on.
