Overheating and mitigation methods

[oj88]

in manila, water boils at 100 degrees centigrade.
in baguio, water boils at 95 degrees centigrade.

That makes sense. Higher elevation has lower atmospheric pressure and even if the cooling system is sealed, will result in a lower absolute pressure... reducing the boiling point of water and/or the coolant.

A coolant mix adds about 25-30°C to the boiling point of water.

You hardly see anyone overheating in the worst Metro Manila traffic (except those with actual engine problems). But then you see all those stalled vehicles heading for Baguio... I love science. :D
