What to do if antifreeze red and green are mixed?Can green antifreeze and red antifreeze be mixed?

As we all know, different brands and models of antifreeze for automobiles cannot be mixed, especially red antifreeze and green antifreeze, let alone mixed addition. Because the composition of red antifreeze and green antifreeze is different, if mixed and added, it will not only fail to play the original role of antifreeze, but may even cause some engine failures.

The main reason is that the main component of red antifreeze is propylene glycol, while the main component of green antifreeze is ethylene glycol. Moreover, the freezing point of the red antifreeze is minus 35 degrees Celsius, and the freezing point of the green antifreeze is 37.5 degrees Celsius. Therefore, if the two antifreezes are mixed, the antifreeze effect of the overall antifreeze may be reduced. Moreover, if the two antifreezes are mixed, other chemical substances may be produced, which is not conducive to subsequent use.

But if the car owner accidentally mixes green antifreeze and red antifreeze during the process of adding antifreeze, there is only one solution. The owner needs to remove the antifreeze that has been mixed, and then add pure water. This pure water must be injected into the antifreeze reservoir, and then let the water continue to flow in the engine cooling system until the water inside becomes clear.

Finally, after the water is drained, new antifreeze can be added, and car owners need to pay attention during the addition process, it must be filled between the highest line and the lowest line. When adding it again, it must be noted that the antifreeze cannot be mixed again. Choose a frequently used brand and type of antifreeze, and do not replace it easily.
