The advantage of anhydrous coolant is that it does not need to be added to the coolant many times, and it has the characteristics of high boiling point and low freezing point, strong thermal conductivity, clean and environmental protection, etc. The old problems of the cooling system such as corrosion have extended the service life of the engine.
The disadvantage of waterless coolant is that it is expensive and the secondary maintenance cost is relatively high. The average car is replaced at least nearly 2000.YuanMoney, a bigger car may cost 2000-3000 yuan. In the event that the vehicle crashes, or parts of the car's cooling system age, causing coolant to leak, it will need to be added. The heat dissipation is lower than that of traditional coolants. If the engine has been working at high temperature, it may cause irreversible damage to various parts of the engine over time.
Why did the 4s shop ask me to change the waterless coolant?
Anhydrous antifreeze is better. After changing it, it can drive up to 800,000 kilometers, because vehicles rarely drive to 800,000 kilometers. Basically, it means that there is no need to change it for life. It is the reason why the 4S shop asks the owner to replace the anhydrous coolant. . The waterless coolant is better than the traditional coolant, which realizes the high temperature cooling under no pressure of the cooling system, and the use time of the engine becomes longer, so that the owner can feel more at ease with the car.
Anhydrous antifreeze is of oil texture, ordinary antifreeze is water quality, and the heat dissipation of anhydrous antifreeze is not as good as that of ordinary antifreeze. The specific heat capacity of water is scientifically the best, and anhydrous coolant absorbs and releases heat. The capacity is only about 60% of the conventional coolant. However, the water content of anhydrous antifreeze is relatively small, and it is not easy to produce scale. It can indeed be replaced once in a lifetime.
