Are there any overheating issues, forget the lite/gage for a moment. Might be a problem with temp gage sending unit? You could use an infra-red temp gun, get engine up to operating temp, lite on, then check the temp reading with the gun. You can double-check the instrument cluster temp gage.
Might be some air in the system. I'd use the recommened lbs for the radiator cap.
