When Does a Car Need to Add Antifreeze?
1 Answers
When the liquid level in the antifreeze overflow tank in the car's engine compartment falls below the lower limit mark, it is necessary to add antifreeze. How to determine if antifreeze is lacking: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to a lack of antifreeze, although it could also be caused by excessively high cylinder temperatures. Check the antifreeze reservoir. If the liquid level is below the minimum mark (MIN), do not continue driving; add antifreeze promptly. Check the water level scale markings on the antifreeze bottle. Normally, antifreeze should be between the maximum and minimum water levels. Whether antifreeze is lacking depends on the scale. If the antifreeze is below the minimum water level, it indicates a shortage. 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 can reduce the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding. Long-life antifreeze can remain effective for up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are found in the antifreeze, replace it immediately and clean the system.
