Problem Description: Engine temperature gauge reading high, steam or coolant escaping, engine power loss. (问题描述：发动机温度表读数高，蒸汽或冷却液逸出，发动机功率损失。)
Possible Causes & Solutions:
Low Coolant Level (冷却液液位低): Check coolant level and refill if necessary. Look for leaks in hoses, radiator, or engine block. (检查冷却液液位，必要时重新加注。 检查软管、散热器或发动机缸体是否有泄漏。)
Faulty Thermostat (恒温器故障): Thermostat may be stuck closed, preventing coolant flow. Replace thermostat. (恒温器可能卡在关闭位置，阻止冷却液流动。 更换恒温器。)
Radiator Blockage (散热器堵塞): Debris or corrosion can block radiator fins, reducing cooling efficiency. Clean radiator externally and flush internally. (碎屑或腐蚀会堵塞散热器翅片，降低冷却效率。 从外部清洁散热器，并从内部冲洗。)
Water Pump Failure (水泵故障): Water pump may not be circulating coolant effectively. Check for leaks, noise, or lack of coolant circulation. Replace water pump if necessary. (水泵可能无法有效循环冷却液。 检查是否有泄漏、噪音或冷却液循环不足。 必要时更换水泵。)
