How Often Should the Coolant in Volkswagen Bora Be Replaced?

[OLeah]

The coolant in a Volkswagen Bora generally needs to be replaced every 2 years or 40,000 kilometers. This is just a reference interval. For commercial vehicles with higher mileage, the replacement interval should be shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Monitor the coolant level and top it up promptly if it is low. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the coolant, it should be replaced immediately, and the system should be cleaned. When replacing the coolant, it is essential to use the same brand of coolant. Different brands may have varying formulations, and mixing them could lead to chemical reactions between additives, rendering them ineffective. The key indicators for coolant are its freezing and boiling points. Available options in the market include coolants with freezing points of -15°C, -25°C, -30°C, and -40°C. It is advisable to choose a coolant with a freezing point at least 10°C lower than the lowest temperature in your region. Additionally, pay attention to the shelf life when selecting a coolant.
