Vacuum leak- almost for sure. Also, check the inlet for the PCV system. If you replace the oil fill cap with a closed type, it will make a whining noise- chased that one for a few days.

i finally figured it out. it is the fan clutch. the fan spins a few seconds after the engine stops. the squeak stops as soon as the fan stops spinning

Wow- I never heard one squeak and keep working. I had one on my 'Yota squeak when it blew apart, and one on an F-600 at work just ripped the water pump off, but never a little squeak. I'd replace that before I needed a radiator. Be a good idea to do a pump at the same time.
