did you bleed all the air bubbles out of your coolant? pop the radiator cap off, start the car and let the car run for a few minutes. watch the top and you should see bubbles come out. do that first and let me know what happens.

Do a compression test on all cylinders to determine the condition of the head gasket. Also if there's a blown head gasket, then you would notice water dripping at the tail pipe or white smoke and possibly constant air bubbles at the radiator fill neck.

If the head gasket is OK, then the thermostat is most likely bad; replace it with a Nissan OEM unit, not some aftermarket unit.
