do a pressure test ... Autozone will rent you a pressure tester for cheap.
is it holding pressure? if not, there's a leak somewhere ...
on a '96, my first instinct after radiator and thermostat would be a leak in the intake manifold.
In the morning, after your engine has completely cooled, open the rad cap. Is it completely full to the brim? It should be.
Also, check your overflow level and that the hoses are not blocked ...
another check would be the temp sensor ...
try to eliminate one thing at a time ...
