当空调打开时,我的汽车过热;仅当A/C打开时才这样做。所有的粉丝都可以很好地工作,新的防冻空气口袋已从系统中清除。我还取代了从散热器软管上连接到发动机的塑料外壳。检查发动机灯不在,但是在行驶3-4英里左右后,发动机温度上升到240以上。什么将解决这些问题?

AC ON的发动机过热通常是由两种可能性之一引起的。一个是由AC压缩机失败。交流压缩机会为发动机增加旋转载荷,如果压缩机佩戴并且越来越难以转动这会导致发动机过热。
第二个常见原因是冷却系统无法有效工作。AC冷凝器在使用AC时加热,因此发动机冷却系统必须处理这种增加的热量。插入或blocked radiator condenser fins, fans not working efficiently or awater pump这并不是循环冷却液都可能仅导致AC过热。
最后的可能性虽然不太可能,因为该车辆通常会读热是否打开,而不是faulty engine coolant temperature sensor。The coolant temp needs to be read out with a temperature gun and needs to compare with the gauge. The radiator and condenser fins should be cleaned of debris. If these items do correct the issue, then you may want to enlist the help of a mechanic, such as one from YourMechanic, who will have the expertise to诊断并纠正过热问题。
