What do the three colors of car antifreeze represent? Does mixing have any effect?

The red antifreeze of automobile antifreeze is generally glycerin, the green one is ethylene glycol, and the blue one is propylene glycol. The color of automobile antifreeze has no special meaning. The difference in the color of antifreeze is only the formula of the manufacturer.

Mixing antifreeze is not allowed. Mixing antifreeze with different ingredients will destroy each other's chemical balance. It may happen that the boiling point of the antifreeze is reduced, and the corrosiveness of the antifreeze is increased.

The full name of antifreeze is called antifreeze coolant, which means coolant with antifreeze function. Antifreeze can prevent the coolant from freezing and expanding and cracking the radiator and the engine cylinder block or cylinder head when the vehicle is stopped in cold winter. Many people think that antifreeze is only useful in winter, but it is not. The boiling point of antifreeze is higher than that of water, it is not easy to boil, its performance is relatively stable, and it will not change with the increase of temperature.

In addition, the antifreeze liquid has a strong heat dissipation capacity, which can take more heat away from the engine, so that the engine will not be hot. Antifreeze has low corrosiveness and will not corrode waterways after long-term use. After high temperature, the antifreeze will not form scale in the waterway, which will affect the heat dissipation of the engine.

When choosing antifreeze, choose one with low freezing point, high boiling point, low corrosiveness, and stable chemical properties. Do not use inferior products. When adding antifreeze, it should be added as required, not too much or too little.
