2000 Toyota RAV 4. 400845 miles. Overheating. Example 1: exiting from interstate-normal temp; 2 blocks-gauge rises close to the red zone very quick then drops back down to normal just as quick. Then goes up-then down, up then down. It moves as quick as the speedometer does. Radiator-replaced; hoses-replaced; thermostat tested as good. Help?
