Does the antifreeze need to be replaced? The antifreeze should be changed every few years

Antifreeze, also known as antifreeze coolant, is a coolant containing special additives. In addition to antifreeze cooling, it also has the effect of anti-corrosion and anti-scaling. Everyone still knows about antifreeze, but few really understand it. Many car owners do not. Know when you should replace it, and if you don't replace it in time, it could cause damage to your car. So,Change antifreeze every few years? Let's take a look below.

Does the antifreeze need to be changed?answer yesOf course need. Antifreeze has a shelf life, the general shelf life is about 2 years, and the high-quality long-term effect can reach 5 years. Antifreeze will not prolong the shelf life because it is not opened. If it is stored for a long time, some internal chemical components may become invalid. Antifreeze will also be oxidized and deteriorated after being used for a long time. At this time, it needs to be replaced. The engine has a certain degree of influence.

In general, antifreeze2It needs to be replaced every year or so, or the car needs to be replaced after driving about 40,000 kilometers. To replace antifreeze, you need to choose high-quality products of the same brand and color.Hot car can not be directly filled with antifreeze, It needs to be added after static car cooling to avoid high temperature burns;

Do not mix antifreeze, Different brands and different colors of antifreeze may have different formula ingredients. If they are mixed, various chemical components may react, which will affect the performance of antifreeze;Do not replace antifreeze with water, water is easy to boil, will produce a large amount of water vapor, seriously affect the cooling effect, and the freezing point of water is high, easy to freeze, the water contains impurities and anions and cations, which will cause scale and blockage for a long time.
