Does Coolant Get Consumed?

[Cinna]

Coolant does get consumed. As an expendable item, coolant will evaporate under continuous high temperatures. Coolant Composition: The main components of coolant are: 50% purified water, 40% methanol, and 10% other substances. How to Choose Coolant: The basic indicators for coolant are freezing point and boiling point. In the market, coolants come with freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it's advisable to choose a coolant with a freezing point at least 10°C lower than the lowest temperature in your region. 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 can be done every two years or every 30,000 kilometers. 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 particles, sediment, or signs of deterioration or discoloration are found in the coolant, replace it promptly and clean the system.
