The benefits of waterless coolant include eliminating the need for frequent coolant top-ups, as well as offering high boiling point, low freezing point, excellent thermal conductivity, and being clean and environmentally friendly. How to choose coolant: The basic indicators of coolant are freezing point and boiling point. On the market, coolants come in specifications such as -15°C, -25°C, -30°C, and -40°C freezing points. Generally, it's advisable to choose one that is at least 10°C lower than the lowest temperature in your region. Can different coolants be mixed? Only coolants of the same brand should be used. Different brands may have varying production formulas, and mixing them could lead to chemical reactions between additives, rendering them ineffective. Coolant replacement cycle: For vehicles that run for long periods, such as taxis, high-quality coolant should generally be replaced once a year. For vehicles with shorter operating times, replacement every two years or every 30,000 kilometers is sufficient. To prevent excessive foam formation, which reduces the heat exchange efficiency between the coolant and engine components, ensure the product is within its validity period when adding it. Long-life coolants can have a validity period of up to three years. If suspended matter, sediment, or signs of deterioration or discoloration are found in the coolant, it should be replaced promptly, and the system should be cleaned.
