When I took the belts off to see if my timing belt had slipped, I noticed that the water pump spins really, REALLY easily by hand. In fact it even keeps turning for a few seconds after being given a twirl by hand. This is not what I expect from a shaft whose other end is supposed to be immersed in coolant solution. I'd expect the coolant to damp the motion of the pump pretty thoroughly.
Could it be that the shaft is broken or the impeller has slid off of the pump or something?
Might I have found the cause for why it seems like it is not running on all four cylinders? If you are not familiar with that pair of threads, the urls are

It has never given any indication of overheating, and the heater works pretty darn well, if not spectacularly. But if it is not circulating, then maybe the head overheated and warped in the middle. With my luck, that is probably just what happened.
Am going out to the car now to do the compression checks mentioned in the above threads. Will post results when available.
Thanks again everyone.
