Where is the car engine coolant located?

[LeMatthew]

Coolant is located in a small pink liquid-filled reservoir on the left side of the engine compartment. Functions of the cooling system: To provide moderate cooling to the operating engine, allowing it to work within the most suitable temperature range. Engine cooling must be properly balanced. Insufficient cooling will reduce engine power, cause oil to degrade due to heat, and decrease the mechanical strength of components due to high temperatures. Excessive cooling leads to excessive heat loss, reducing engine performance and fuel efficiency, increasing oil viscosity, and intensifying friction and wear between moving parts. Precautions when using coolant: Prevent coolant leakage, as leakage not only results in coolant loss but severe leakage can dilute engine oil, causing lubrication system failures; avoid contact with skin; use coolant year-round consistently, paying attention to the continuity of coolant usage.
