Should the coolant in the Hongguang S be replaced directly or just topped up when low?
1 Answers
If the coolant in the Hongguang S is low, it can be topped up, but it is important not to mix coolants from different manufacturers. Since different brands of coolant have different formulations, mixing them can cause chemical reactions. Typically, coolant has an effective service life of two years. If it expires or appears dirty, it should be replaced. How to determine if the coolant is low: Check the coolant warning light on the dashboard. If it lights up, it is likely due to low coolant, though it could also be caused by excessively high engine temperature. Inspect the coolant reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and add coolant promptly. Check the water level markings on the coolant overflow tank. The coolant level should normally be between the maximum and minimum marks. To determine if coolant is low, observe the markings. If the coolant is below the minimum level, it indicates a shortage. Coolant replacement interval: For vehicles that operate for long periods, such as taxis, high-quality coolant 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 coolant and engine components, ensure the product is within its validity period when adding it. Long-life coolant can remain effective for up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the coolant, replace it immediately and clean the system.
