What to Do When the Coolant Level Warning Light Comes On?

[Tobias]

The solution for a coolant level warning is: you need to top up the antifreeze. If the water temperature reaches above the red line, it's best not to continue driving. If you can't add antifreeze immediately, consider stopping the car to lower the water temperature. If the water temperature is normal and only the antifreeze warning is on, you can continue driving, but monitor the water temperature during the drive and top up the antifreeze as soon as possible when conditions allow. The functions of automotive coolant include: 1. Preventing the car's radiator and engine block from cracking due to freezing in low-temperature environments; 2. Preventing corrosion in the cooling system; 3. Reducing scale formation during circulation; 4. Absorbing heat to keep the radiator from boiling under high temperatures.
