<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." > 東風教練車提示發動機過熱是一個常見的故障，就會發生引擎動力，經濟衰退，嚴重時會損壞零件，因此應排除故障。以下介紹的規則引擎過熱故障的“四步法”。
看看它是發現溫度太高或溫度指示燈不停閃爍，檢查停車在水箱，冷卻水是正常的，水箱，管道和接頭有無滲漏現象。如果外部檢查發現異常，可以使所需的冷卻水，然后繼續運行。如果運行距離短，仍然發現溫度太高，停車檢查冷卻水降低了很多，這主要是由于氣缸體水套砂孔或穿孔和損失。發現這一故障，應進行維修，不要失望。
2觸摸發動機溫度太高，可用于接觸水上、水下管道溫度來確定故障位置。如果兩者溫差很大，可以發現一個恒溫設備不工作。在中途的時候不買零件，可以去除恒溫裝置緊急，回到單位后立即更換。
三placeif冷卻系統的空氣，可以形成的空氣阻力，使冷卻水循環，導致發動機溫度太高。可以采取以下做法通貨緊縮：讓發動機高速運轉，水箱蓋輕輕擰下才有一個氣體釋放，這一次將一部分的冷卻水與氣體流出，如此反復多次，直到你感到氣體放電。故障排除后，及時補充冷卻水。四punchif長時間運行的車輛在道路上或泥濘的道路上，會有一些污垢粘附在散熱器，在適當的時候，會影響冷卻效果，因水溫過高。可以先用壓縮空氣吹散熱器格柵，再用清水洗凈。
