How Often Should the Antifreeze in Fengyun 2 Be Replaced?

[Beckett]

Fengyun 2 antifreeze should be replaced every two years or 40,000 kilometers. Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head during cold winter parking. When adding car antifreeze, ensure the product is within its validity period. It must be replaced regularly, and it is recommended to use the same brand of antifreeze. 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 reduces the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-life antifreeze can have a validity period of up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are found in the antifreeze, replace it promptly and clean the system. Methods to determine a lack of antifreeze: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to a lack of antifreeze, though it could also be caused by excessively high cylinder temperatures. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and add antifreeze promptly. Check the water level scale markings on the antifreeze tank. The antifreeze level should normally be between the maximum and minimum marks. To determine if antifreeze is lacking, check the scale. If the antifreeze level is below the minimum mark, it indicates a shortage of antifreeze.
