I got ten bucks says the WP has bound up some how and the impeller is not turning.
I hope this is not the case, but every thing that has been posted sure points in that direction.

The fact that the upper radiator hose is gets very hot and the level is rising in the reservoir would seem to indicate that the water pump and the thermostat are both functioning. This along with the fact that the lower hose remains cool, seems to lead to the conclusion that the radiator is blocked somehow which would be really bad.
I guess you could drain the radiator and try to back flush it with a garden hose to see if anything comes out. Past that you'd need to pull it.
Good luck.

How do you come to that conclusion?
The fact that the coolant level is rising tells me a different story.

Look at the waterpump pulley.We paint code the pulley and cover to the drive sprocket.If the water pump is not turning the paint marks will not be lined up.
And if they are not lined up,then that means the coupler did it's job.There is too much resistance against the pump to turn it or the belt is not tensioned properly. Ed

Not so with the WP he has installed. It's designed to let the TB track normally whether the WP has totally seized or not. Sounds like the innovation may be acting counter-productively, though.
Also, the fact that the top hose is hot and the lower hose is cool concludes that there is no circulation. There is no debating that. I agree with Greg. Go ahead and think worst-case scenario because it 99% sure ain't the t-stat. Go ahead and throw it into some boiling water to be sure it is opening of course. Have you contacted Ed?

As for the rising level in the reservoir, I've had this happen before when my car was overheating. The radiator was clogged and the pressure from the WP on the blocked radiator would cause the level in the reservoir to rise. This was with the cap off. Not sure what we have in this case, but it seemed logical. Why this would happen all of a sudden is not clear, but with these cars, I'm never surprised.

please answer these questions, yes or no will work...
After installing the new WP did you turn the pulley by hand to see if it spun freely?
Is the belt tensioned correctly?
Did you remove the thermostat and inspect the rear seal??
Did you replace the thermostat?
Did you open the heater to full hot prior to running the engine?
Did you let the engine warm up with the cap off??
Did you replace the cap after the fans come on and drive the car with the heater on full hot for about 5 miles and park it let it cool and top up as necessary?
Can you smell any burning rubber from the vent holes on the cam towers?
Does the engine temp go to just under the red zone in under 5 minutes at idle??
Please list all of the parts that you replaced on this job

Sorry, didn't catch the fact that it was one of the new fail-safe pumps. Saw that at Frenzy, very cool design. Hard to believe it would fail immediately on installation unless the impeller is jammed into the block. Did you rotate the WP pulley by hand before you put the T-Belt on?
