Should You Add Water or Antifreeze to a Car's Radiator?

[StRemington]

A car's radiator should be filled with antifreeze. If water is added instead, scaling may occur when the water heats up, potentially clogging the cooling system. Generally, vehicle antifreeze should be replaced every 2 years or 40,000 kilometers. This is just a reference interval. For commercial vehicles with higher mileage, the replacement cycle should be shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Regularly check the antifreeze level and replenish it promptly if it is insufficient. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the antifreeze, replace it immediately and clean the system. The key indicators of antifreeze are its freezing point and boiling point. Market-available antifreeze comes in various freezing points, such as -15°C, -25°C, -30°C, and -40°C. It is advisable to choose an antifreeze with a freezing point at least 10°C lower than the lowest temperature in your region. Always use the same brand of antifreeze. Different brands may have varying formulations, and mixing them could lead to chemical reactions among the additives, rendering them ineffective.
