Why does the BMW 5 Series show a coolant warning when the coolant level is sufficient?
1 Answers
BMW 5 Series shows a coolant warning when the coolant level is sufficient due to insufficient water in the engine cooling system. Here is some relevant information about coolant: Main functions of coolant: It provides anti-corrosion protection for components of the cooling system. It prevents scale formation and reduces radiator temperature. It ensures the engine operates within the normal temperature range. Therefore, when the coolant is low, it directly affects the radiator's cooling efficiency. When the water temperature is too high, the red coolant warning light on the dashboard will illuminate. If the engine is not turned off and continues to run, it may cause engine seizure and damage. Coolant replacement cycle: The coolant replacement cycle should follow the manufacturer's manual. Typically, it should be replaced every 2 years or 40,000 kilometers, with the longest interval being every 4 years or 60,000 kilometers. A few car manufacturers offer coolant that supports lifetime replacement, only requiring regular checks. Since this type of coolant has slightly poorer fluidity, it is important to ensure the cooling system's circulation and heat dissipation are functioning properly. Regularly monitor the coolant level to ensure it stays between the minimum and maximum marks.
