What is the difference between red and green car antifreeze

After the car has been driven for a long time, it needs to do comprehensive maintenance and care, and many car owners only know how to change the oil, but do not know that antifreeze is also very important. Antifreeze plays a very special role in the car, but some car owners The difference between red antifreeze and green antifreeze may not be clear.

The color of different antifreeze represents the difference in chemical composition. The main component of red antifreeze is propylene glycol, and the green one is ethylene glycol.

The chemical composition is different, which also proves that the effect of antifreeze of different colors is different. Green antifreeze is easier to catch fire and evaporate, and is suitable for ordinary cars. Other high-performance cars do not carry green antifreeze, but are more suitable for red antifreeze. Red antifreeze is also more suitable for use in cold areas. .

Therefore, when choosing antifreeze, you need to choose the appropriate antifreeze according to the ambient temperature in your area.

It should be noted that antifreeze of different colors cannot be mixed together. Mixing red and green antifreeze will not only affect the effect of antifreeze, but also cause chemical reactions to cause adverse effects on the engine. . If it is really necessary to replace the antifreeze of other colors, then the water tank should be fully cleaned before replacing it.

The difference between different colors of antifreeze is the knowledge that car owners need to know, so that they can better maintain and check their cars.
