How often is it most appropriate to change the antifreeze for cars?

Speaking of antifreeze, as the name implies, it is to prevent the car from being injured in cold conditions, and another important function is to cool the engine, so there will be less and less antifreeze as time goes by. So the old driver suggested that you check the content of antifreeze for about a year. If the antifreeze is not enough, it is recommended that the owner buy the appropriate antifreeze and add it directly, without the trouble like engine oil!

Generally speaking, the antifreeze assembled by the original automobile factory has the best effect, and most automobile 4s shops provide free antifreeze addition service. As long as they don't have enough antifreeze, call the 4s shop to make an appointment, and they can add it for us! However, although antifreeze lasts for a long time, there is still a certain time limit.

Generally speaking, the original antifreeze can be used for about 10 years. When we find that the color of our engine fluid has changed, it proves that this engine fluid has been used up, and the overall use effect will definitely be bad! Just replace it at this time, there is no need to keep staring at antifreeze!
