Can green and red antifreeze be mixed?

[LaSimon]

Green and red antifreeze cannot be mixed because they have different formulations, which would affect the performance of the antifreeze. The reasons for their different colors are: 1. To distinguish antifreeze with different ratios. Both water and antifreeze agents are colorless, making it impossible to distinguish different ratios of antifreeze by sight, so different dyes are added for differentiation; 2. To clearly identify leaks in the antifreeze, making it easier to locate the leak point; 3. To easily monitor the consumption of antifreeze in the radiator and replenish it in time; 4. To prevent accidental ingestion and to distinguish it from water easily. The protective functions of antifreeze include: 1. Providing anti-corrosion protection for components of the cooling system; 2. Preventing scale formation to avoid reducing the radiator's cooling efficiency; 3. Ensuring the engine operates within the normal temperature range.
