Did the coolant boil and puke out of the overflow? If not I know there is a resistor that went bad on my 190% temp guage so I replaced it with my stock 160% guage and it was the 190% gauge malfunctioning. Other than that it is important to raise the rear of the car when replacing the coolant and open the air bleeder screws at the top of the radiator to eliminate air from the system. Also check that the fans are working and blowing the air in the correct direction.
