What is the method for adding coolant?

[LeNatalie]

Coolant filling method is: 1. Open the front hood and tighten the radiator drain switch; 2. Pour coolant into the radiator until it overflows; 3. Tighten the radiator filler cap; 4. Fill the engine coolant into the reservoir. The functions of coolant are: 1. Prevent corrosion of metal parts and aging of rubber components; 2. Prevent freezing and cracking of the radiator or engine cylinder block due to coolant freezing during parking in cold seasons; 3. Prevent engine water temperature from becoming too high, ensuring the engine operates at normal working temperature; 4. Reduce scale formation to avoid clogging circulation pipes and affecting the cooling system's heat dissipation function; 5. Provide lubrication for the water pump thermostat and other components.
