Generally speaking, it is not recommended to mix antifreeze. If you accidentally mix antifreeze, it is best to quickly drain the antifreeze in the water tank, then rinse the water tank with water, and then add new antifreeze into it.
Why can't antifreeze be mixed?
Car owners and friends who often buy antifreeze know that the antifreeze packaging on the market has different colors. The common ones are red, green and blue. The reason for distinguishing different colors is because the main components of antifreeze are different. Generally speaking, the main component of green antifreeze is ethylene glycol, the main component of red antifreeze is propylene glycol, and the main component of blue antifreeze is diethylene glycol.
And different chemical components will react together, if you mix different types or brands of antifreeze:
1. It will break the proportioning balance of antifreeze, reduce the performance of antifreeze, and directly lead to the failure of antifreeze;
2. After the chemical reaction, sediment may be formed. Once the sediment blocks the pipes of the cooling system, the heat dissipation of the engine will be affected. After a long time, the engine will be damaged quickly;
3. Corrosive substances may be formed after the chemical reaction. If the sealing rubber of the cooling system is corroded, the cooling system will not work.
Therefore, it is best not to mix antifreeze, and make sure that the composition of antifreeze is consistent before adding antifreeze.
If you accidentally add other components of antifreeze, to be on the safe side, it is best to remove all the antifreeze in the water tank, rinse the water tank before adding new antifreeze, if there is not much antifreeze, it is better to add drinking pure water , and do not mix with antifreeze.
In addition, it should be reminded that the ingredients of antifreeze in the same packaging color are basically the same, but there are exceptions, so it is best to carefully read the ingredients marked on the packaging when purchasing. If you do not understand, you can directly consult the clerk. , to avoid buying inappropriate antifreeze, damage to the engine and cooling system is not worth the loss.
Antifreeze is very important for cars, so remember to check regularly when using antifreeze. If it is lower than the minimum standard value, it should be added in time. If there is turbidity in the antifreeze, it should be replaced in time. It is best to measure the antifreeze before winter. Liquid freezing point to prevent antifreeze from freezing.
