However, it won’t be a problem if you mix a small amount of traditional antifreeze with OAT. If you mix one of these coolant types with another one, it will weaken the corrosion inhibitors of the stronger one. It comes in orange or yellow color and has a lifespan of up to 5 years.

Hybrid Organic Acid Technology (HOAT): As the name suggests, this type is a mix of traditional and OAT coolant types. Instead of having phosphates and silicates, it has neutralized organic acids and azoles as corrosion inhibitors. Organic Acid Technology (OAT): Available in orange and red colors, OAT is the coolant of newer models. This type has silicates and corrosion inhibitors known as phosphates. Inorganic Acid Technology (IAT): With a bright green color, IAT was the coolant of older vehicles up to the mid-90s. They have slightly different ingredients from each other, which affects their efficiency and lifespan. What Happens If You Mix Different Coolant Types? Colors don’t indicate the type and mixing two different types will definitely reduce the efficiency of the one or other type. However, what you should be careful about is the type of coolant. You can mix various colors of coolant without any problem. So, color is just an identifier and you can mix coolant of different colors without any problem. If the coolant is orange, it has definitely been produced by General Motors. It’s just different companies use different colors, so consumers know which product they are using just by looking at it.įor example, Honda sells blue coolant, Texaco and Shell produce the green variant, while Prestone sticks to the fluorescent yellow. It does not indicate any difference in the properties of the coolant. The antifreeze color is something like food coloring. What is the right thing to do? Can You Mix Pink and Green Antifreeze? Many car owners think that mixing up two different colors of antifreeze increases their efficiency while others avoid this practice thinking that it destroys their properties. Can you mix pink and green antifreeze for having a better result? Rust and deposits can clog up a cooling system but the antifreeze has rust inhibitors to prevent this issue. In a similar fashion, it stops the fluid in the car to freeze in the cold season.

It helps with heat dissipation in hot weather to save the engine from overheating. Diluted with distilled water, this liquid is used in a car’s cooling system. Coolant or antifreeze is a vital liquid that your engine needs for proper functioning.
