Can antifreeze of different colors be mixed a little?
1 Answers
Antifreeze of different colors cannot be mixed. Different colors indicate different compositions, and mixing antifreeze with different ingredients can cause chemical reactions, leading to the antifreeze losing its effectiveness or even solidifying. Even if the antifreeze is the same color but from different brands, the stabilizers may vary, and mixing them can reduce cooling and cleaning performance. Therefore, it is best not to mix them. Ideally, use antifreeze of the same brand and color. If antifreeze is accidentally mixed, the antifreeze in the radiator must be completely drained, flushed with purified water, and then refilled. Antifreeze typically comes in colors such as green, blue, pink, and some may even have a fluorescent effect. Generally, ethylene glycol is green, propylene glycol is blue, and glycerol is pink. Manufacturers dye antifreeze different colors for the following purposes: Prevent mixing: To avoid confusion with other liquids and prevent accidental ingestion, many manufacturers add different color formulations for distinction. Easy identification of leaks: When the engine leaks, the color makes it easier to detect and diagnose during inspection and repair. Safety considerations: These chemical components in the engine are toxic, so liquids like windshield washer fluid and antifreeze are dyed to prevent accidental ingestion.
