So at what temperature will an engine overheat and cause damage or break down? My 440 (stock radiator and 7-blade fan) normally runs at 180-200 degrees. Was doing a charging test idling in drive for 15 minutes and it crept up to 230. As soon as I started driving, the temp dropped back to 180. When should you pull over?
t-stat might have not opened sitting? 180-200 is fine. 230 is fine if you are not running that temp all the time. The concern I have is if it continues to creep beyond 230 if you leave it sit even longer.
