故障现象随着气温逐渐升高,近期我公司多辆苏州金龙城市客车(型号为KLQ6116G,搭载锡柴CA6DF2-24发动机)在行驶过程中出现冷却液温度过高的故障现象,故障发生时冷却液温度表指针达到红色警戒线,严重影响了客运班车的正常运营。故障诊断在笔者接手前,维修人员曾换过节温器和冷却液泵等,但故障仍未排除。接车后试车,发现冷却液温度上升较快,很快就超过了冷却液温度表的红色警戒线。笔者首先检查了散热器及其进液管和出液管的温度,温度
Symptoms As the temperature gradually increased, the recent company I Suzhou City, Jinlong City Bus (model KLQ6116G, equipped with Xichai CA6DF2-24 engine) occurred in the course of the coolant temperature is too high fault phenomenon, the fault occurs when the coolant Thermometer pointer reached the red cordon, seriously affecting the normal operation of the passenger bus. Troubleshooting Before I took over, the maintenance staff had changed thermostat and coolant pump, but the fault is still not ruled out. After the test car and found that the coolant temperature rose rapidly, soon exceeded the red line of the coolant temperature gauge. The author first examined the radiator and its inlet and outlet of the tube temperature, temperature
