When replacing the traditional coolant with anhydrous coolant, pay attention to the oil temperature, because the anhydrous antifreeze is oily, the ordinary antifreeze is water, and the heat dissipation of the anhydrous antifreeze is not as good as that of the ordinary antifreeze. , The specific heat capacity of water is scientifically the best. Although the anhydrous coolant is better than the traditional coolant, the capacity of the anhydrous coolant to absorb and release heat is only about 60% of that of the traditional coolant. If the engine has been working at a high temperature, it may be affected for a long time. Irreversible damage to various parts of the engine.
What should I do if the waterless coolant is changed by a 4S shop?
If the car owner is fooled by the 4s shop to switch to anhydrous coolant, there is no big problem. After all, the anhydrous coolant is good or bad. If you are really worried, you can switch back to ordinary coolant. Find a repair shop that is relatively large. Generally, the charging price of the 4s shop is more expensive than the charging price of the repair shop. Drain all the anhydrous coolant and replace it with ordinary coolant. It is necessary to thoroughly clean the water channel when replacing it, because the oily substance without water coolant is difficult to clean.
The advantage of anhydrous coolant is that it does not require multiple additions of coolant, and at the same time has the characteristics of high boiling point and low freezing point, strong thermal conductivity, clean and environmental protection, and eliminates the corrosion, scale and gas caused by traditional coolant to the engine. The old problems of the cooling system, such as eclipse, make the service life of the engine prolonged.
