At what temperature does antifreeze freeze?
I’m moving to a state that has really bad winters, and I keep hearing I need to get a special antifreeze for my car so it won’t freeze. Can antifreeze really freeze up in cold weather?

Your new neighbors are right! It might seem counterintuitive, but despite the name,
antifreeze
can freeze. This typically happens at around -5 degrees Fahrenheit. But keep in mind that what you’re putting in your car isn’t actually pure antifreeze—it’s coolant. Coolant is a combination of antifreeze and water, typically as a 50/50 mixture.
As strange as it sounds, adding the water to antifreeze actually lowers the freezing point. That’s why coolants are sold as different ratios of antifreeze to water, with different freezing points:
- 100/0 (pure antifreeze: Freezes at 0 to -5 degrees Fahrenheit
- 50/50 (standard coolant): Freezes at -35 degrees Fahrenheit
- 70/30 (cold-climate coolant): Freezes at -67 degrees Fahrenheit
For harsh winter climates, 70/30 coolants are recommended.
