What did you do to test it? It really sounds as if the water is not circulating through the engine

1.Try running the car with no thermostat at all, see if it stays below 200, if it does, then the thermostat was bad.

2.Try putting a new radiator cap on, there needs to be 16lbs of pressure in the system, caps go bad too.

3. When was the last time you flushed the system, are you running a 50/50 water/antifreeze mix? Flushing will also help dtermine if you have any blockage as well.

4. As goodyear mentioned, the clutches on those stock fans are crap not to mention useless if you have removed the fan shroud or if it's broken. It's purpose is to help draw air through the radiator.

5. Double check the waterpump, brand new ones from the parts stores can be bad from the start, it happens all the time. Also look at your belt routing, if your using a short belt, be sure to keep the same directional pull as the stock belt...
6. Finally, try adding some water wetter, it works.

Really all I can think of here...besides maybe your gauge is acting up, which I doubt. Try some of this and let us know....Good luck.
