Why Does the Antifreeze in a Car Decrease?
1 Answers
The decrease in antifreeze in a car is due to three main reasons: natural consumption, coolant leakage, and antifreeze entering the combustion chamber and participating in combustion. How to Choose Antifreeze: The basic indicators of antifreeze are its freezing point and boiling point. On the market, antifreeze comes in several specifications with freezing points such as -15°C, -25°C, -30°C, and -40°C. Generally, it is advisable to choose an antifreeze with a freezing point at least 10°C lower than the lowest temperature in your region. Can Different Antifreeze Brands Be Mixed? It is necessary to use the same brand of antifreeze. Different brands of antifreeze may have varying production formulas. If mixed, the various additives may undergo chemical reactions, rendering them ineffective. Antifreeze Replacement Cycle: For vehicles that run for long periods, such as taxis, high-quality antifreeze should generally be replaced once a year. For vehicles with shorter running times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foam formation, which can reduce 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 matter, sediment, or signs of deterioration or discoloration are found in the antifreeze, it should be replaced promptly, and the system should be cleaned.
