How many liters of antifreeze should be added to a car's radiator?
1 Answers
A car generally requires about 4 liters of antifreeze. Antifreeze prevents the coolant from freezing during cold winter parking, which could otherwise cause the radiator to crack or damage the engine cylinder block or head. How to choose antifreeze: The basic indicators of antifreeze are its freezing point and boiling point. In the market, antifreeze comes in specifications with freezing points of -15°C, -25°C, -30°C, -40°C, etc. It is advisable to choose one with a freezing point at least 10°C lower than the lowest temperature in your region. Can antifreeze be mixed? It is necessary to use the same brand of antifreeze. Different brands of antifreeze may have varying production formulas, and mixing them could lead to chemical reactions between additives, rendering them ineffective. Antifreeze replacement cycle: For vehicles that operate for long periods, such as taxis, high-quality antifreeze should generally be replaced once a year. For vehicles with shorter operating times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-lasting antifreeze can have a validity period of up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the antifreeze, it should be replaced promptly, and the system should be cleaned.
