How Many Kilometers to Add Coolant?

[DelCaroline]

Generally, coolant should be added every 2 years or approximately 40,000 kilometers. This is just a reference interval. For commercial vehicles like taxis or ride-hailing cars that are used frequently and accumulate more mileage, the coolant replenishment cycle should be shorter. Introduction to Coolant: Antifreeze refers to coolant with antifreeze properties. It prevents the coolant from freezing in cold winter conditions, which could otherwise cause the radiator to crack or damage the engine cylinder block or head due to expansion. Many people think antifreeze is only used in winter, but in fact, it should be used year-round. When to Replace Antifreeze: The color of the antifreeze in the reservoir has changed significantly compared to its original color; sediment or floating impurities are visible in the antifreeze; the antifreeze level has dropped below the minimum mark; testing shows the antifreeze's freezing point is insufficient. The engine temperature is too high, requiring further investigation.
