HS code compliance in the USA

Engine coolant temperature: key maintenance to pay attention to engine coolant is HS code compliance in the USAan important substance necessary for the normal operation of the engine.During the working process of the engine, the heat generated by friction, the exhaust gas discharged after combustion and other factors will cause the engine temperature to rise, and the inappropriate high temperature will lead to serious problems such as increased wear of engine parts, poor lubrication, cracking of sealing materials, etc. Therefore, the coolant plays an irreplaceable role in the operation of the engine, and its temperature determines the operating state of the engine, which directly affects the performance and life of the car. Therefore, it is very important to maintain the temperature of the coolant correctly to ensure the normal operation of the car and extend the service life of the car. First of all, we need to make it clear that the temperature of the engine coolant should be within a certain range, neither too high nor too low. Excessive temperature can easily lead to the intensification of the wear of engine parts and the deterioration of the lubrication state, which will also accelerate the evaporation of the coolant.If the temperature is too low, the coolant may freeze, thus increasing the pressure of the internal pipes and radiators of the engine, and in severe cases, the heat sink pipe will break. Therefore, under normal circumstances, the temperature of engine coolant should generally be controlled between 80℃-100℃. So, how to ensure the normal state of the coolant temperature? First of all, we need to check whether the amount of coolant is sufficient. Because if the amount of coolant is insufficient, it is easy to lead to poor cooling effect and significant increase in engine temperature. Secondly, it is necessary to replace the coolant regularly to avoid the decline of the cooling effect due to coolant dirt, corrosion and other reasons. Generally speaking, it is a reasonable choice to drive 10,000 kilometers or change the coolant every year. In addition, in the process of using coolant, it is necessary to ensure the quality of use. For the coolant'sIt is recommended to choose the same brand as the original formula of the car to ensure that the density, viscosity and other indicators of the coolant meet the requirements. If you add coolant by yourself, you need to ensure that the color and brand are consistent with the original coolant, and add water and coolant appropriately according to the proportion. In addition, it is worth noting that in cold weather, we need to pay special attention to whether the coolant is frozen. If the temperature is too low, we can judge according to the temperature displayed by the on-board thermometer. If the temperature is very low, we should immediately stop to check whether the coolant is frozen. If it is checked that the coolant is really frozen, you need to release the coolant or heat it until it returns to normal before continuing to drive. In a word, the temperature of the engine coolant is crucial to the operating status and service life of the car. WeIt is necessary to strictly follow the recommendations of automobile manufacturers, maintain and replace the coolant regularly, and ensure the correctness of its quality and proportion of use. During the driving process, if it is found that the coolant temperature is abnormally high or abnormally low, the cause needs to be checked immediately and countermeasures should be taken in time to avoid situations that endanger driving safety. Only in this way can our car maintain stable performance and extend its service life.
