What is the normal position of antifreeze?
2 Answers
Antifreeze should normally be between the MAX and MIN marks, which can be checked at the antifreeze reservoir. It is generally recommended to replace it every 2 years with a volume of 4 to 5 liters. After replacement, the cooling system should be bled. Using waterless antifreeze can effectively reduce coolant erosion on the engine, prevent scale formation, and extend the service life of the cooling system. The full name of antifreeze is antifreeze coolant, which is a type of coolant containing special additives. The main component of most antifreeze is ethylene glycol, as it has a high boiling point and low freezing point, ensuring normal vehicle operation in cold climates without freezing, while also providing cooling effects when the engine overheats. It is an indispensable automotive product.
The normal position of the antifreeze is in the coolant reservoir in the engine compartment, and the fluid level must be maintained between the MIN and MAX marks. The most accurate check is when the engine is cold. A level that is too low can cause engine overheating or even cylinder scuffing, while a level that is too high may lead to expansion leaks and damage other components. It is recommended to check the fluid level once a month when washing the car to ensure it is within the middle range. If it is low, top it up with antifreeze of the original factory specifications, and avoid mixing different types to prevent chemical reactions. A clear color indicates good health, and it is safer to change the antifreeze every two years, especially before long trips. This helps protect the radiator and engine, avoiding the hassle of major repairs.
