![]() It is important to know that, when mixing, the color is not an important factor, but the chemical composition of the antifreeze, you should mix only identical ones from identical antifreeze classes. It is not recommended to mix antifreeze of different brands and colors, but there are some situations in which you have to do this. One thing you should take into account is that the two types of antifreeze should be heated at 80-90 degrees Celsius or 176 -194 degrees Fahrenheit for the test to be more accurate. If after 10-15 minutes you did not see any bad reaction such as foam formation, sediments on the bottom, and the composition has not thickened then this mixing is said to be safe. This requires samples from both types that can be mixed in a transparent recipient. You can make a few tests by yourself by mixing two different antifreeze. G12 +, G12 ++ and G13 can be mixed with each other Įven if you make this combination, when it’s possible you should drain out the mixed composition, flush the cooling system and add fresh coolant that is recommended by the car manufacturer just for safety reasons.it is not recommended to combine G12 with G12 ++ or G13.if absolutely necessary, you can mix coolant G12 with G12 +.mixing G11 with G12 + and G13 is allowed.As I have said above, mixing any coolant from those two types is not allowed, but mixing types of antifreeze is possible under certain circumstances, which I will list below.Ĭheck the label on the antifreeze recipient, it will tell you the class of antifreeze (G11, G12, or G13). The color of the antifreeze is not a condition for mixing different types of antifreeze, but rather the substances that they are made of. If you have done that mix, you will need a specialist that will thoroughly flush the entire cooling system and then add fresh coolant. The protective properties of those two types of antifreeze will be eliminated in the chemical reaction produced.Īlso, the foam will be produced in the expansion tank and system pipes which will cause bearings to wear out faster, the cylinder head to overheat and deform, but also the water pump to fail. By mixing those two types of antifreeze the consistency of the coolant will thicken leading to clogged pipes, and bad circulation in the cooling system.įurthermore, the engine and the oil will overheat leading to possible serious damage. Mixing a G11 antifreeze type, which includes the green one, and a G12 type, where the orange one is included, is the worst possible combination that it can be made. What happens if you mix orange and green antifreeze? Also, they have a longer lifespan, and changing it is not that often as in the case of G11 and G12 classes. It is colored pink or purple and are mostly used in newer car models. Its basis, instead of ethylene glycol, is propylene glycol. Available in red, sometimes yellow colors. In terms of properties, they are similar to the G12+, and their main difference is a longer lifespan. For their manufacture, an organic base and silicic acid compounds are used. The components that are available in G12+ antifreeze may differ, it depends on the manufacturer and they are most often in red color. Moreover, there is G12 + which is a mixture of water, ethylene glycol, and additives. They have a lifespan of up to 2 years and are mostly used in older car models, therefore, they should be changed more often. Its composition is similar to G12, but it does not include carboxylic acids. What features does green antifreeze have? They have a lifespan of up to 5 years and have a wide range of use. Its composition is based on ethylene glycol, water, and additives ( borates, nitrites, etc.), but additionally, they include compounds of carboxylic acids. But not always! What features does orange antifreeze have? Therefore, they are considered versatile and suitable for refilling. They combine the chemical elements of both previous categories. In addition, there is another type of antifreeze, like G13. It can also have anti-corrosion properties that are more commonly used in G12 and G12 +. The antifreeze protects pipes and other cooling elements from aggressive effects by forming a thin layer film. These additives and substances are needed to neutralize the destructive effect of water and ethylene glycol on the metal parts of the cooling system, in particular cooling system pipes and the radiator. The remaining 20% are additives that have special characteristics to a particular coolant type. ![]() What happens if you mix orange and green antifreeze?Īntifreeze contains 80% of distilled water that is mixed with ethylene glycol.What features does green antifreeze have?.What features does orange antifreeze have?. ![]()
