The full name of antifreeze should be antifreeze coolant, which means coolant with antifreeze function. In winter, antifreeze is very important for trailers. The trailer engine and its cooling system are made of metal. These metals will corrode and rust if they are in contact with water at high temperature for a long time. Common antifreeze is mostly alcohol, which reduces the electrochemical corrosion between the engine parts compared with distilled water. In addition, antifreeze itself will add rust inhibitors, which makes antifreeze can greatly reduce the corrosion of the cooling system.
Generally speaking, antifreeze is replaced every two years, but this time is not fixed. If ordinary water has been added to the antifreeze, the replacement cycle should be advanced. Check the antifreeze frequently during use. Check the height of the oil level and add it in time if it is less; then check the freezing point to ensure the normal effect of the antifreeze. The freezing point of antifreeze on the market has several main specifications such as -25℃, -35℃, and -45℃. It is more appropriate to choose antifreeze with a freezing point that is 10℃ lower than the temperature in the area.
