It just scared me i've always been told normal temp for a car is 180 and water boils at 210 so i figured it was gonna blow up.
WATER boils @ 212 and freezes at 32 (assuming sea level)...
Anti-Freeze/COOLANT doesnt.
properly MAINTAINED coolant wont boil til somewhere north of
250...if you are concerned you can test the coolant quality/condition
and concentration.
if you know its gonna be called upon for more extreme (than normal)
duty you could flush the system, add new coolant (and distilled water,
to avoid deposits & minerals) and increase the concentration.
depending on the coolant, read & heed the manufactures suggested
concentration levels...but generally you shouldnt go more than 60-70%
coolant concentration.
