Conclusion: Maintaining a healthy cooling system

In conclusion, maintaining a healthy cooling system is essential for preventing the mystery of disappearing coolant. It is crucial to regularly monitor your engine coolant levels and address any signs of leakage or coolant loss promptly.

One of the key preventive measures is to check for visible leaks or drips under your vehicle. Inspect hoses, connections, and the radiator for any signs of damage or wear. Additionally, ensure that the radiator cap is tightly sealed to prevent coolant from escaping.
