Maintenance of the cooling system requires targeted measures based on specific faults. Common issues include coolant leakage, poor heat dissipation, and component damage. If coolant leakage is detected, inspect the radiator, hoses, and seals. Minor cracks can be temporarily repaired with a specialized leak sealant, while severe cases require replacement of the radiator or hoses. Water pump failures are usually accompanied by abnormal noise or leakage and should be replaced promptly to prevent circulation interruption. A clogged radiator should be cleaned using reverse compressed air flow or descaled with a specialized cleaning agent to maintain heat dissipation efficiency. Thermostat malfunction may cause abnormal coolant temperature; its operational status can be tested by immersing it in hot water, and replacement is necessary if defective. For routine maintenance, check the coolant level biweekly and replace the coolant every two years or 40,000 kilometers, avoiding mixing different antifreeze brands. In emergencies such as coolant boiling, shut off the engine and allow it to cool naturally. Never open the radiator cap immediately; only replenish with the same specification antifreeze to the proper level after complete cooling. Regularly inspect the fan belt tension and radiator surface cleanliness, replacing aged hoses promptly. Proper maintenance significantly extends engine lifespan, though complex issues should be addressed by certified technicians to guarantee repair quality.
