Yes it is possible for antifreeze to freeze up if the temperature gets cold enough.

Antifreeze will not freeze up at most normal cold weather temperatures as long as the antifreeze has been mixed properly in your engine.

If you put straight antifreeze in the engine then it will freeze at a temperature of between zero and minus five degrees Fahrenheit.

Adding water to the antifreeze makes the freezing point lower so it would take a colder temperature of below 30 F or so before the antifreeze froze up.

But as long as you mix the antifreeze properly or use the premixed antifreeze and coolant in your vehicle then the antifreeze or coolant should never freeze as long as you do not live in some place really, really cold.
