When many car owners add antifreeze, because they can't see the highest and lowest scale lines, they often add too much. There is an overflow valve that allows excess antifreeze to drain out by itself.
Although there will not be much harm, the antifreeze will leave more unsightly stains after drying. If the driver has a container, he can choose to extract the excess antifreeze. The antifreeze is in the It can be between the highest scale and the lowest scale, and the extracted antifreeze can be used next time.
When using antifreeze, we need to pay attention to the following points:
1. Try to use the same brand of antifreeze, because different brands of antifreeze may have some differences in the production formula. If they are mixed, it may cause some chemical reactions, resulting in loss of antifreeze effect.
2. Generally speaking, the validity period of most antifreeze is about two years, and some products may be slightly longer, so we should confirm whether the antifreeze is still within the validity period before adding it.
3. When using antifreeze, we must remember that it must be replaced regularly. Under normal circumstances, it should be replaced once after it has been used for two years or has driven more than 40,000 kilometers. When replacing, the old antifreeze should be replaced. Take it all out, then clean the cooling system, and then replace it with new antifreeze.
