Does antifreeze you put in a car radiator have a lower or higher freezing point than water?

Antifreeze, typically made from ethylene glycol or propylene glycol, has a lower freezing point than water. This property allows it to prevent the coolant in a car radiator from freezing in cold temperatures, which helps maintain engine performance and prevents damage. When mixed with water, antifreeze lowers the overall freezing point of the solution, providing effective protection against freezing.
