What’s good about it is that it has a lifespan of up to 5 years. Lastly, you will find Hybrid Organic Acid Technology (HOAT), a mixture of the above coolants.OAT coolants offer the same protection as “normal” green antifreeze but are usually better in newer vehicle applications. It is also available in orange, yellow, red and purple. Unlike IAG, they don’t contain any silicates or phosphates but azoles and neutralized organic acids. Then there is Organic Acid Technology (OAT), suitable for new cars.They are available in green (most common), red or orange color. They have properties like phosphates (used as a corrosion inhibitor) and silicates. Typical coolants you’re likely to find in the market contain Inorganic Acid Technology (IAG), suitable for an old car.Three types of coolants that you should know: With antifreeze & coolant, there is a wrong coolant and a right coolant depending on the application, brand of vehicle and where you live.

This blog will take a closer look at coolant brands and tell you if it’s safe to mix different coolant brands. But it’s best to match that as well – because each coolant has special additive packages that help with corrosion, performance and coolant flow. The color doesn’t matter as much since it’s just a dye.

The short answer is that you can mix different coolant brands and mixtures as long as they are the same type of coolant. Hence, I decided to put together this article to shed some light on this. I once also found myself in the same situation. You’re not the only motorist feeling like that. You might be wondering if it’s possible to mix coolant brands? Perhaps there are instances when you find yourself buying different coolant brands but are unsure if this is safe for your engine?ĭon’t fret. You have green, orange, pink, red and blue coolant circulating through radiator hoses in cars around the world.īecause of all this variety, it’s important that you don’t mix the wrong coolant, or wrong types of coolant mixtures, the next time you’re topping off your coolant level.
