Why does the BMW 3 Series suddenly prompt to add coolant?
1 Answers
Reasons are as follows: The coolant warning indicates that the antifreeze level is below the electrode level, preventing the circuit from conducting. The vehicle's computer interprets this signal as insufficient antifreeze, triggering the warning light. When the coolant warning appears, it is essential to stop the vehicle promptly. After the water temperature drops, wait for more than ten minutes before checking the antifreeze level. If it is insufficient, replenishment is required. If the level is normal, further inspection at a repair shop is necessary. Below is additional information: Coolant, fully known as antifreeze coolant, refers to a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing during cold seasons when the vehicle is parked, which could otherwise cause the radiator to crack or damage the engine cylinder block. However, it is important to correct a misconception: antifreeze is not just for winter use; it should be used year-round. In regular vehicle maintenance, the engine antifreeze should be replaced every year of driving.
