不要在引擎里形成锈蚀和污泥,以免冷却系统受害。这就是为什么经常冲洗水箱的原因。清洗水箱是车辆保养的重要因素,但往往被许多驾驶员忽略。车辆的冷却系统保护本身免于被引擎产生高热损坏,并保持引擎本身运转于适当温度范围里。保持冷却系统免于锈蚀、积聚和污染,会使它和引擎处于良好工作状况。 Do not form rust and sludge in the engine to avoid damage to the cooling system. This is why you often wash the water tank. Tank cleaning is an important factor in vehicle maintenance, but often overlooked by many pilots. The vehicle’s cooling system protects itself from being thermally damaged by the engine and keeps the engine operating within the proper temperature range. Maintaining the cooling system free from corrosion, build-up and contamination will keep it in good working condition with the engine.
