大部分车主在补充防冻液时会直接添加同类型防冻液，这种看似最科学的方式实

Most car owners will directly add the same type of antifreeze when replenishing antifreeze. This seemingly the most scientific way is actually wrong. Because EG is an oily liquid with poor volatility and its boiling point is as high as 197.4 ℃, the normal operation of the engine cooling system will never reach this high temperature, so the rate of EG volatilization reduction will be very slow. This is also the reason why the EG aqueous solution can achieve the cooling function at the same time, because it will continue to absorb heat before reaching the boiling point, and other parts of the water will not boil. However, in high-temperature environments, water will evaporate without boiling. The part of the coolant that naturally decreases during the use of the car is mainly water; then after the reduction, the coolant is supplemented with EG and water at the same time. The ratio will increase, it is hard to say whether the freezing point of the coolant will exceed 60%, and it is naturally impossible to judge whether the lowest temperature of the environment where the vehicle is used can be applied. <br>2: To ensure that the ratio of coolant EG to water does not change, the most ideal way is (3 + 1). Refers to that after the normal loss of the coolant, the water is replenished three times according to the amount of the loss, and the fourth time due to the small amount of EG volatilization, the coolant can be replenished to achieve equilibrium. This is the way to ensure that the coolant is closest to the original car standard. For a performance car with faster coolant loss, the two-wheel replenishment basically reaches the point of overall replacement, and the engine cooling system will maintain the most ideal working conditions.

Most car owners add the same type of antifreeze directly when they add antifreeze, which seems to be the most scientific way to actually be wrong. Because The EG is a fluid-like liquid with poor volatilization, and its boiling point is as high as 197.4 degrees C, the engine cooling system will not always reach this high temperature, so the EG volatilization reduction will be very slow. This is also the reason why the EG aqueous solution can achieve cooling function at the same time, as it will continue to absorb heat until boiling point has reached, while the water in the rest will not boil. But in high temperature environment water does not boil will also evaporate, in the use of the car in the course of the natural reduction of coolant is mainly water, then after the reduction of coolant is also supplemented with EG and water, and then reduced again, the proportion of EG will be increased, the freezing point of the coolant will be more than 60% is not good to say, can apply the lowest temperature naturally can not be judged.<br>2: In order to ensure that the ratio of coolant EG to water does not change, the ideal way is (3-1). Refers to the normal loss of coolant, according to the amount of loss equivalent to supplement the water three times, the fourth time due to the small amount of eG volatilization can supplement the coolant to achieve equilibrium. This is to ensure that the coolant is closest to the original vehicle standard, for the coolant loss of faster performance vehicles, after two-wheel replenishment basically reached the overall replacement node, the engine cooling system will maintain the best operating conditions.

Most car owners will directly add the same type of antifreeze when adding antifreeze, which seems to be the most scientific way is actually wrong. Because eg is an oil-like liquid with poor volatility, and its boiling point is as high as 197.4 ℃, the normal operation of engine cooling system will not reach this high temperature, so the rate of reduction of EG volatilization will be very slow. This is also the reason why eg aqueous solution can realize the cooling function at the same time, because it will continue to absorb heat before it reaches the boiling point, and other parts of water will not boil. However, water will also evaporate if it does not boil in high-temperature environment. The main part of the natural reduction of coolant in the process of using the car is water. After the reduction, the supplement of coolant is to supplement eg and water at the same time, and then reduce and supplement again. The proportion of EG will increase. It is hard to say whether the freezing point of coolant will exceed 60%. It is impossible to judge whether it can be applied to the lowest temperature environment of the car site Broken.<br>2: In order to keep the ratio of EG and water unchanged, the best way is (3 + 1). It means that after the normal loss of the coolant, the water shall be replenished for three times according to the loss amount. In the fourth time, the coolant can be replenished for equilibrium due to a small amount of volatilization of eg. This is the way to ensure that the coolant is closest to the standard of the original vehicle. For the performance vehicle with fast coolant loss, the overall replacement node is basically reached after two wheels supplement, and the engine cooling system will maintain the most ideal working condition.<br>
