120 cel. is 254 degrees and it says that it is getting up to 120cel (254 degrees F~), but when i check the raidiator and thermostat housing id is only 198 degrees F~ (80 to 90 cel) which is normal.

so is my gauge broke ? do i have maybe a fraid wire? the car is not overheating!

overflow is at a normal 170 degrees F~
