    The most effective thing I did to my cooling system was drill a couple small holes in the thermostat flange. Let's just enough coolant flow that it almost has a hard time getting up to temp. But, I live in a relatively cool place and don't have ac.

    I did that too.
    It helps to prevent an air pocket when you fill the system with coolant.

    Get yourself a pulley puller/press and press your power steering pulley on. Even the slightest bit will make that squeak go away. I've had this happen on a number of vehicles and it drove me insane listening to it and trying to find it. I couldn't tell with the naked eye that my power steering pulley was not perfectly lined up with the rest. You may notice a little ware on the edge of the belt as well.

    A noisy squeaky belt is a common problem on HVAC systems. Most of the time it is from worn pullies. The same is on a cars belt systems. Pullies do "wear" out and the groove no longer matches up to the belts "V" profile. This can causes a squeaky noise. As noted, pully aligned is important also.

    Thanks for the input.
    A/C and power steering both work with no noise when the only belt installed is the PS and A/C belt.
    It's a new belt for that and it's also a new A/C compressor.

    The noise is definitely in front of the engine and the only common factor in my diagnostics is the water pump.

    Could try using a stethoscope to locate the squeak. But i am with you on the problem pointing to the water pump.

    I tried the stethoscope and it didn't seem to pinpoint the noise to the water pump.

    But the WP is the only logical thing that is making noise after removing the various belt combinations and having the noise stop when the water pump wasn't being driven.
    The slight play in the WP shaft seems to confirm it.

    You should have 0 play in your water pump. The bearings and seals should not let it move it all. Usually all high-performance water pumps usually push about 20% more through them the standard pump.

    Yup if the water pump belt is off and the noise stopped I thing you have found your trouble Terry, but there could always be that mouse hiding behind the pulley.
