What is the indicator for low coolant?

[AylaLee]

The indicator for low coolant is a small sailboat-like symbol on the dashboard. The functions of automotive coolant are: 1. To provide anti-corrosion protection for the engine's cooling system; 2. To prevent the engine water from boiling when the temperature reaches 100 degrees Celsius; 3. To prevent the formation of scale, which can reduce the radiator's cooling efficiency; 4. To ensure the engine operates properly in low temperatures. The method for replacing coolant is: 1. Open the vehicle's engine hood, and the coolant reservoir can be seen in the upper right corner; 2. Open the coolant drain plug under the radiator to drain the old coolant; 3. Add new coolant, tighten the cap, and the coolant replacement is complete.
