How long is the replacement cycle of antifreeze coolant?

Most family cars are replaced every two years or 40,000 kilometers. Of course, this is only a reference replacement cycle, which can be changed according to the actual use situation, because walking an extra one or two million kilometers or the use cycle is extended for more than a year and a half, so there is no problem. If the intensity of the car, it can be replaced in advance.

However, if the antifreeze coolant is found to be less than the minimum scale value (the normal capacity of the antifreeze coolant should be between MIN and MAX) within the period before replacement of the antifreeze coolant, it shall be increased timely, otherwise, it will affect the cooling efficiency of the engine.
