It's fixed!!! Believe it or not, what I guessed above was actually right on. When I changed the radiator the lower rad hose clamp was really hard to get tight because of the angle of the spicket. I thought it was on there good but apparently it was slowly leaking, and that caused it to overheat and let the coolant level get really low. Then after refilling the coolant (and tightening that hose clamp better) an air bubble remained in those two hoses, restricting the flow. Today I was able to get the air out of the system and now it's all better.
And the thermostat I still need to put back in there. It actually runs about 20 degrees cooler than normal (190 F rather than 210 F) with the thermostat out.
