Where is the coolant added?

Coolant is added to the small reservoir located under the engine hood in front of the engine coolant. The full name of coolant is antifreeze coolant, which has antifreeze properties. It prevents the coolant from freezing during cold seasons when the vehicle is parked, thereby avoiding the expansion and cracking of the radiator and freezing damage to the engine cylinder block. The functions of coolant are: 1. Prevent the coolant from freezing during cold seasons when the vehicle is parked, avoiding expansion and cracking of the radiator and freezing damage to the engine cylinder block; 2. Prevent corrosion of metal parts and aging of rubber components; 3. Reduce the formation of scale to prevent clogging of circulation pipes and affect the heat dissipation function of the cooling system; 4. Prevent the engine water temperature from becoming too high, ensuring the engine operates at the correct working temperature; 5. Provide lubrication for the water pump thermostat and other components.
I recently topped up the coolant myself. The container is called an expansion tank, usually a translucent plastic reservoir in the engine bay with MIN and MAX markings. Never open the cap when the engine is hot - last time I nearly got scalded by steam. Wait until the engine cools completely. Always use the same color coolant as original - never mix green with blue as different formulations can coagulate and clog the system. When refilling, stop just below the MAX line to allow for thermal expansion. Coolant isn't just for winter antifreeze protection; it also prevents summer overheating. Running low can cause cylinder damage. I recommend checking levels monthly and replacing it every two years for optimal maintenance.
