Automobile antifreeze, which can protect the engine in low temperature environment, and can also take away the heat generated by the engine work, has many types. Some car owners will ask, can red and green antifreeze be mixed? The answer is not to mix, because the additives used in the two types of antifreeze are different, and mixing them together will cause a chemical reaction, causing it to lose its original effect.
Automobile antifreeze has different colors, which is set by the manufacturer to prevent car owners from mixing different types of antifreeze together.
Antifreeze red or green?
At present, most of the antifreeze can be used in all models. In our daily life, we see more red and green antifreeze. So how to choose these two antifreeze? Our car owners can choose according to their advantages and disadvantages, as well as the road environment in which the vehicle drives daily, as follows:
Advantages and disadvantages of green antifreeze
The green antifreeze on your car is ethylene glycol antifreeze. The performance of this antifreeze is relatively good, its freezing point reaches minus 37.5°, and its boiling point reaches 107.5°, which can fully meet the working needs of the engine, and the price is relatively cheap. However, the stability of this antifreeze is not good, and it is easy to be oxidized and lose its effect in long-term use. And this antifreeze is more difficult to degrade, so it will cause great environmental pollution after failure.
Advantages and disadvantages of red antifreeze
Our common red antifreeze is called propylene glycol antifreeze. Its performance is slightly inferior to that of ethylene glycol antifreeze. The freezing point is minus 35° and the boiling point is 105.5°. However, this antifreeze is not easy to oxidize, and its stability is better than that of ethylene glycol antifreeze, so its service life will be longer. But in terms of price, it is more expensive than ethylene glycol antifreeze, generally tens to more than one hundred yuan.
Then, when our car owners choose antifreeze, they should choose according to the local minimum temperature. Generally, the freezing point of antifreeze should be selected about 5 degrees Celsius lower than the local minimum temperature, so as to ensure that its effectiveness is not affected by the ambient temperature.
How much antifreeze to add?
The last thing to remind car owners is that there will be a maximum scale line and a minimum scale line on the antifreeze tank. When our car owners add antifreeze, they only need to add it to the middle of the two scale lines. Higher than the highest scale line or lower than the lowest scale line will affect its work.
