Can blue and red antifreeze be mixed together?

[DiLeilani]

Blue and red antifreeze cannot be mixed because different brands and manufacturers use varying components and additive ratios. Although the main ingredient is primarily ethylene glycol, the additives differ. Even antifreeze products from the same manufacturer may vary in composition based on color. Precautions for mixing antifreeze: Always use antifreeze from the same brand. Different brands have distinct production formulas, and mixing them may cause chemical reactions between additives, rendering them ineffective. Therefore, avoid mixing antifreeze whenever possible. Functions of antifreeze: Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It provides excellent performance in winter freeze protection, summer boil-over prevention, year-round scale inhibition, and corrosion resistance. The main components of antifreeze are: 50% purified water, 40% methanol, and 10% other substances.
