I just purchased a 2001 Z06 with 37,000 miles on it. The only concern that I have is the temp gauge will move from 190 degrees to 230 degrees. Is this normal and if so is their any thing that I can do to keep it form moving in to such high tem zones. My friends 2003 Cobra is always at the 200 mark and never moves no matter how much he abuses the engine. As I have noticed with most cars that the temp gauge doses not move after a certain point. Someone please help with some insight thanks.
