Check the coolant reservoir cap. The system is pressurized and a bad cap can cause the symptoms you are seeing. Not likely, but one more thing to check. I had a problem with a car I couldn't get to cool after a minor front end collision. Burped the hell out of it, new thermostat, cleaned it. finally replaced the radiator and it worked great. 150k miles on it and I think the "bump" dislodged some crud or damaged it internally.
