Change the sensor. Check the electric cooling fans and Relays. Some fans have 2 speeds and may not kick into high speed.
The radiator operates more or less closely to the block temperature. A Laser thermometer would tell you what the operating temperature is.

1. Check the level you filled the coolant to...If you overfilled it this will happen. 2. Did you add the correctly diluted antifreeze? 3. Check to be sure the radiator is unobstructed
SOURCE: temp guage keeps pegging out to high side.....
LOL, dont add to the environmental mess just yet!
have you replaced the sending unit for the gauge? its located usually in the intake manifold somewhere, or on one of the cylinder heads.
If thats not the problem, you may have a wire grounding out behind the dash.
my best advice is to try an aftermarket monitoring gauge with fresh wiring to the sending unit or sensor to check for this problem... hope this helps!

I doubt if it is the temperature sensor if the gauge is working. Check to see if the fans are coming on when the engine is hot. The fans have two speeds and should come on in low speed and change to high speed as temperature gets hotter or when air conditioner is turned on. If they are working correctly. I would guess the radiator is partially plugged up between the air conditioner condensor and the radiator. These cars are bad about getting dirt, lint, and what ever trapped in this area.

Have you replaced the thermostat as this could be sticking and causing your problem. Also i see you have flushed the rad but you still may have a blockage get a radiator shop to check flow rate

It could be both your thermostat and water pump, it could also be an air lock in your cooling system. One way or another, I think pressure is building up in part of the system because its not circulating properly.
When its cool, take the top off your reservoir, give the bottom hose to your radiator a good few squeezes, see if the water goes down a little, if it does, you moved something on and probably cured it.
If not, run the engine up, to get it warm and bleed off any air in the system. (Assuming there are bleed taps in the system)
If that also does nothing, I reckon its your water pump. And if your changing that, I'd suggest changing the thermostat at the same time.
