squeaky noise help!

On cold starts and expecially when I run my AC I hear a loud squeaky noise on my car. I just replaced the alternator belt and I replaced the tensioner and its belt.What else do you experts think it may be?

I put a stethoscope to every possible part and it sounds like it may be the water pump.

What do you guys think?

Where can I get a good water pump from?

Have you ever changed the balancer? That's what mine was...

Was just going to mention this. I hear squeaky belts are one of the symptoms of the harmonic balancer coming apart. I was not lucky enough to get any subtle symptoms before mine let go....

I had some "chirping" and found the upper tensioner had a wobbly pulley so I changed it and the belt out.

So then the chirping continued, but different. I tried listening with a piece of garden hose and for some reason could NOT find the pulley that was chirping.

I suspected I might have the "wobbly balancer" syndrome as it just looked like it was shaking just a little.

Took it to a locally renowned Corvette guru and he said the balancer was fine, it was the AC tensioner/idler....and the water pump.

All quiet now.

Not sure if this really helps you but that was my experience.
