The antifreeze (coolant) needs to be replaced. The replacement cycle of most automotive antifreeze is two years or 40000 km. The use efficiency of antifreeze will be reduced after a long time, so it needs to be replaced. This is an important thing related to the heart of your car - the engine, so it needs to be replaced regularly.
It should be noted when purchasing that some antifreeze must be mixed with water in proportion to play a "role". Many car owners use it directly without reading the instructions when they buy it, which eventually leads to the engine "boiling". Therefore, no matter what kind of antifreeze they buy, it is better to read the instructions before use to ensure that there is no risk.
In order to prevent the water tank and engine block from cracking due to the freezing of antifreeze after parking in winter, it is required that the freezing point of antifreeze should be about 10 ℃ lower than the low temperature in this area in case of sudden weather change. High quality antifreeze is eye-catching in color, clear and transparent, and has no peculiar smell; Use a beaker to heat the antifreeze solution, and use a thermometer to measure its boiling point. Only if the boiling point is above 100 ℃ can the antifreeze solution be genuine, and if the boiling point is less than 100 ℃, the antifreeze solution is counterfeit.
