Is the coolant boiling and coming out of the radiator vent tube? If not, the engine is not overheating. The temp in the 200 degree range isn't excessive as long as you've got a good pressure cap. A 14 lb. cap will raise the boiling point of the coolant to 254 degrees F. at sea level. You could easily run 220 degrees or so with no damage to the engine. Chances are the radiator is a little dirty or your temp gauge is lying to you. I'd suggest using a laser pointer temp gauge and checking the temperature of the thermostat housing above and below the thermostat. Then check the temp of the water pump inlet to see how efficiently the radiator is functioning. A good radiator will drop the coolant temp around 50 degrees or a little more. Do you have a fan shroud on the car?
