<P src="""Engine overheating is a common fault, it will lead to occurrence of engine power, economic decline, serious when can damage the parts, so the fault should be excluded. Following the presentation of rule engine overheating failure "four step method".A look atIt is found that the temperature is too high or temperature indicator light does not stop shining, to check for parking at the water tank, cooling water is normal, water tank, pipes and joints have no leakage phenomenon. If the external examination abnormalities were found, can make up the required cooling water and then continue to run. If running a short distance, still found the temperature is too high, check for parking and cooling water to reduce a lot, this is mostly due to gas cylinder water jacket sand holes or perforations and loss. Discovery of this fault, should be carried out to repair, not to let down.Two touchThe engine temperature is too high, can be used to touch on the water and under the water pipe temperature to determine fault location. If the two water temperature difference is very large, can be found as a thermostat device does not work. On the way if the moment does not buy into parts, can remove the thermostat device emergency, to return to the unit immediately after replacement.Three placeIf the cooling system in air, can form the air resistance, so that the cooling water circulation, leading to the engine temperature is too high. May adopt the following practices deflation: let the engine running in high speed, the cistern cover gently unscrew to just have a gas release, this time will be part of the cooling water with gas from flowing out, so repeated several times, until you feel the gas discharge. After troubleshooting, timely replenishment of cooling water.Four punchIf the long time running vehicle on dirt road or muddy road, there will be some dirt adhesion on the radiator, in the course of time, will affect the cooling effect, caused by excessively high water temperature. Can be the first to use compressed air blowing radiator grille, reoccupy water wash." > 东风教练车提示发动机过热是一个常见的故障，就会发生引擎动力，经济衰退，严重时会损坏零件，因此应排除故障。以下介绍的规则引擎过热故障的“四步法”。
看看它是发现温度太高或温度指示灯不停闪烁，检查停车在水箱，冷却水是正常的，水箱，管道和接头有无渗漏现象。如果外部检查发现异常，可以使所需的冷却水，然后继续运行。如果运行距离短，仍然发现温度太高，停车检查冷却水降低了很多，这主要是由于气缸体水套砂孔或穿孔和损失。发现这一故障，应进行维修，不要失望。
2触摸发动机温度太高，可用于接触水上、水下管道温度来确定故障位置。如果两者温差很大，可以发现一个恒温设备不工作。在中途的时候不买零件，可以去除恒温装置紧急，回到单位后立即更换。
三placeif冷却系统的空气，可以形成的空气阻力，使冷却水循环，导致发动机温度太高。可以采取以下做法通货紧缩：让发动机高速运转，水箱盖轻轻拧下才有一个气体释放，这一次将一部分的冷却水与气体流出，如此反复多次，直到你感到气体放电。故障排除后，及时补充冷却水。四punchif长时间运行的车辆在道路上或泥泞的道路上，会有一些污垢粘附在散热器，在适当的时候，会影响冷却效果，因水温过高。可以先用压缩空气吹散热器格栅，再用清水洗净。
