Introduction
Antifreeze, also known as coolant, is vital to keeping your engine running at the right temperature in both hot and cold weather.

In this guide, we break down the average prices, types of antifreeze, and what factors influence cost so you can make the right choice for your vehicle.
What Is Antifreeze?
Antifreeze is a chemical solution—usually a mix of water and ethylene glycol or propylene glycol—that regulates engine temperature by preventing freezing in the winter and overheating in the summer. It also protects your engine and radiator from corrosion and scale buildup.

FAQs
Can I mix antifreeze brands?
It’s best not to. Mixing different formulas (e.g., IAT with OAT) can reduce effectiveness or cause gelling.
Can I use water instead of antifreeze?
Only in emergencies—and never in freezing weather. Water lacks corrosion protection and will freeze or boil over more easily.
Does AutoZone accept used antifreeze?
Some locations do, but always call ahead to confirm.
How often should I change my antifreeze?
Every 2–5 years depending on the type used. Follow the service schedule in your owner’s manual.
