我部一辆东风EQ1090汽车行驶时,发动机出现了过热现象,冷却水的消耗量增加很快。但停车检查时,发现发动机冷却系统并无漏水痕迹。只在高速运转时,蒸气引出塑料管有少量水溢出。打开散热器盖时,发现冷却水有往上涌的现象。检查发动机气缸体水套内无明显积垢,气缸盖水道孔无堵塞,且气缸垫密封情况也良好。当检查到散热器时,发现散热器被风扇叶片碰坏后,修理时将冷却管截断过多。为此怀疑故障原因可能在散热器,更换了一只新的散热器后,发动
I Dongfang EQ1090 a car driving, the engine appeared overheating, cooling water consumption increased rapidly. But parking inspection, found no signs of engine coolant leakage. Only when steam is running at high speed, there is a small amount of water in the plastic pipe leading to the steam outlet. Open the radiator cover, found that there is a surge of cooling water phenomenon. Check the engine cylinder block water jacket no significant scaling, cylinder head waterway hole is not blocked, and the cylinder gasket seal is also good. When the check to the radiator, radiator found to be damaged by the fan blades, the cooling pipe when repaired too much. Suspect the cause of the malfunction may be in the radiator, after replacing a new radiator, start
