whiring sound after water pump and timing belt

I noticed that some other people have had the experience of a whining sound
after replacing the water pump and or the timing belt.  I have this sound
as well.  Most noticeable right as one turns the car off, the sound is the
last thing to stop.  What is it and when will it go away?  Mileage? Tire,
Temperature?  I tried water-wet in the radiator, thinking that it was the
pump.  Sure lowered the driving temperature, but the sound is still there.
