The full name of antifreeze is antifreeze coolant. It has three functions. When a vehicle is not started, it can prevent icing. Because the antifreeze is in the cylinder block, the volume of the liquid will expand when it becomes a solid, so the cylinder block will freeze. Another function is to cool the engine after the vehicle starts. Prevent engine damage due to excessive engine temperature. Antifreeze also plays a role in managing rust prevention and preventing pipe blockage caused by excessive scale. The antifreeze is usually replaced every 2 years at about 6W km. If the antifreeze is not replaced for a long time, the antifreeze quality will change, which will reduce its internal rust resistance, and the radiator and pipeline will be damaged. In addition, it will affect the boiling point and freezing point parameters, antifreeze effect or cooling effect, which is harmful to the engine. Don't wait for the antifreeze to turn black before replacing it. If the antifreeze turns black, it means that the antifreeze has deteriorated badly. A lot of scale is also formed. The pipeline has been damaged. So you can use the freezing point meter to check the freezing point of the antifreeze every time you perform maintenance. If the freezing point is too high, the antifreeze has deteriorated and needs to be replaced
Note 1: Try to use antifreeze of the same brand. Different brands of antifreeze have different production formulas. If they are used together, chemical reactions between various additives are likely to occur, resulting in additive failure.
Note 2: The term of antifreeze is usually two years (some products are longer). When adding antifreeze, it should be confirmed that the product is within the term.
Note 3: It needs to be replaced regularly, usually every two years or every 40000 km. Taxis should be replaced more frequently. When replacing, drain the old liquid, clean the cooling system, and then replace it with new liquid.
Note 4: Avoid mixing water.
