Can you mix coolant brands?
My husband accidentally bought the wrong brand of coolant we’ve been using. Can I mix coolant brands in my car?

Thankfully, the short answer is, yes, you can mix two brands of coolant. They just have to be the same type of coolant. Different coolants do different things, and mixing two different types of coolants can damage your radiator. Check the bottles to see if they are the same type.
Here are some common types of coolant that could be on your bottles:
- Inorganic Acid Technology (IAT): Contain phosphates and silicates, good for older cars, most commonly found in green.
- Organic Acid Technology (OAT): Contain azoles and neutralized organic acids, good for newer cars, comes in all colors.
- Hybrid Organic Acid Technology (HOAT): A mix of the two above, lasts up to 5 years, comes in all colors.
As long as you aren’t mixing coolant technology, you should be good to mix brands.
