Having repalced the spilled coolant when replacing the thermo does not tell you it is correctly filled; only that you repalced what was lost........

If it was mine, I'd pull the rad cap, let it get hot and see if it wanted to burp again (jack the nose up 6" off the ground) or would accept more fluids. Shouldn't get much more than 100-105C with the cap off if its full of coolant and the WP is working as there is no pressure present to increase temps beyond boiling. Its easy to get fluid out of the rad, I'd flood it til it overflowed.

If temps soar with the cap off, it ought to mean that fluid isn't circulating properly and whats sitting in the engine is therfore working overtime and overheating.

An IR Thermo would be a fun tool to play with to help figure out whats happpening in that event.
