Answer:
Antifreeze
Explanation:
That sounds like a contradiction, doesn't it?
Antifreeze lowers the freezing point of the water in your car's cooling system.
It also raises the boiling point and protects against boil overs.
A 50:50 mixture of ethylene glycol/water boils at 106 °C (223 °F). If the car radiator has a 100 kPa (15 psi) cap, the boiling point increases to 126 °C (258 °F).
