In this case, the antifreeze fluid turns yellow within a few days after being changed. It is possible that inferior and unqualified antifreeze fluid was used, which caused a chemical reaction to deteriorate the quality of the antifreeze fluid. It may also be due to improper use and rust.
It is not normal for the antifreeze to turn yellow. If this happens, it is best to replace the antifreeze as soon as possible, drain the old antifreeze, clean the water tank and cooling system, and then add new antifreeze.
If the antifreeze fluid deteriorates, its function has failed and cannot protect the engine. If it continues to be used, it will have a certain impact on the engine. If the water temperature rises and the engine works at high temperatures, it may penetrate the cylinder gasket and increase the wear of parts. , If it is serious, there will be a burning jar phenomenon.
In the process of using the antifreeze, always pay attention to the situation of the antifreeze. If there is an abnormal phenomenon, such as the color change mentioned above, replace it in time. Also observe the remaining amount of antifreeze. If the level of the antifreeze is lower than the "min" mark, it means that the antifreeze is insufficient, and the antifreeze should be added in time to keep the antifreeze level at the two scales of "max" and "min". Between the lines.
As time changes, the antifreeze will also fail. Therefore, the antifreeze should be replaced regularly. Generally, the life cycle of antifreeze is about 2 years or 40,000 kilometers, and for operating vehicles such as taxis, the antifreeze can be replaced once a year.
