[0002] With the continuous progress of automobile technology, the performance of the automobile cooling system has become increasingly important. Coolant is a crucial fluid in the automobile cooling system, which can effectively help the engine maintain the appropriate working temperature. However, as the use time increases, the coolant will gradually lose its cooling effect due to factors such as temperature, contaminants, bubbles, etc., and must be replaced regularly. The traditional method of replacing coolant usually relies on manual operation, which is not only time-consuming and laborious, but also easy to cause improper operation to cause coolant leakage and pollution, or not completely remove the old coolant during the replacement process, affecting the replacement effect.

The traditional equipment usually does not have effective temperature control means, which easily affects the injection effect of the coolant, and at the same time, in the traditional replacement equipment, the heating and stirring process of the coolant is usually not efficient enough, which may cause the temperature of the coolant to rise slowly, prolonging the replacement operation time.
