With coolant and about 14 psi, the actual boiling point is around 250
degrees Fahrenheit.

You only need the cooling fan when the ram air at the front of the
vehicle is reduced such as stop & go traffic. Usually when cruising @ 55
MPH the fan never cycles on (excluding a/c operation). So if your trip
is highway speed you're ok but I'd avoid stop & go operation. Having
said that just remember that using the 102*C "safety net" means that the
cooling system is ABOVE the boiling point..............
