Car antifreeze every few years to replace

The antifreeze of the car is generally used for two years or according to the driving conditions of the vehicle.mileageWhen a certain number of kilometers is reached, replace it in time. Most of the time when the mileage of the car reaches 20,000 kilometers or 40,000 kilometers, the antifreeze fluid needs to be replaced for the car. During this period, no matter whether the antifreeze is opened or not, its shelf life is actually only about two years.

Therefore, once it reaches two years, the antifreeze must be replaced. The main reason is that the function of antifreeze is not only to prevent the vehicle from being frozen. Anti-boiling, anti-corrosion heat transfer and so on. It can be said that the automobile antifreeze plays a pivotal role in the operation of the vehicle, so if you want the car to run well, you need to check and replace the antifreeze in time.

Because if the antifreeze is not replaced in time, the following effects will be caused. First of all, the antifreeze is not replaced regularly. When the antifreeze expires, some impurities will be generated in the antifreeze, and some of the original effects will be lost. Secondly, the moisture inside the antifreeze will continue to evaporate over time, resulting in unsatisfactory cooling effect. And the effect of antifreeze will also be unsatisfactory; Finally, changing the antifreeze fluid from time to time will also affect the anti-fouling and anti-corrosion ability of the antifreeze fluid itself, and shorten the service life of the engine.

Therefore, when the antifreeze of the owner's car reaches the service life or the number of kilometers, it must be replaced in time. Moreover, it is not possible to add antifreeze directly during the replacement process, because the vehicle is not completely cooled at this time, but it is very likely that the spilled liquid will splash on the owner and cause burns to the owner.
