Remember, if you are running coolant/antifreeze in your system, there is no need to get nervous about running at 212F/100C. One of the purposes of the coolant is to raise the boiling point of the fluid. If properly mixed, your boiling point will be over 230F. If you are not running coolant/antifreeze, drain your system and add it now. It is vital to keeping the engine healthy as it also acts as a corrosion preventer.
