Can antifreeze of different colors be mixed together?

[DeEverett]

Antifreeze of different colors cannot be mixed together. Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It has excellent properties such as preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year. Antifreeze cannot be mixed: You must use the same brand of antifreeze. Different brands of antifreeze may have different production formulas. If mixed, various additives may undergo chemical reactions, causing the additives to become ineffective. Methods to determine if antifreeze is low: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to low antifreeze, although it could also be caused by excessively high cylinder temperatures. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving; add antifreeze promptly. Check the water level scale on the antifreeze bottle. The normal antifreeze level should be between the maximum and minimum marks. Whether antifreeze is low depends on the scale. If the antifreeze level is below the minimum mark, it indicates a shortage of antifreeze.
