What is the discoloration of antifreeze

The antifreeze we are talking about today can be said to be one of the necessities of a car. It can not only prevent the car from "boiling" (excessive temperature), but also effectively prevent freezing when parking in cold areas. To a certain extent, it can also play a role in preventing corrosion and scale. Then some friends will ask, what is the discoloration of the antifreeze, let's answer it for everyone below.

If the antifreeze fluid changes color, it is probably due to the deterioration of the antifreeze fluid, which not only does not have a good antifreeze effect, but also reduces the cooling effect of the engine. Then when the engine is running at high temperature, the viscosity of the oil will be reduced due to the lack of good cooling effect, and the parts of the engine will be worn over time, and it may even be scrapped directly. We must know that the maintenance cost of the engine is not low, so we should pay attention to the replacement cycle of the antifreeze.

Of course, it may also be because the antifreeze is mixed with some engine oil, which leads to this phenomenon. It is because the oil radiator or filter has a problem. Of course, there is also the possibility of seal aging. As for the consequences, although it is not as serious as the deterioration of antifreeze, it has an impact on its own efficacy.
