發動機過熱怎麼回事? 發動機過熱怎麼處理
冷卻系統是發動機的重要“器官”，如果怠慢了，發動機就會出現高溫或低溫現象。發動機過熱與人體一樣，是件十分可怕的事情，嚴重時常常會引起機件損壞。發動機過熱基本上有以下三種原因:冷卻液虧竭，散熱器部件工作不良，迴圈管路出現故障。
1）發動機過熱，首先從儀錶板上的冷卻液溫度錶反映出來。
一旦冷卻液溫度錶指標進入”紅區“就應立即停車檢查如果是冷卻液虧損，會伴隨冷卻液報警燈閃亮。因此，駕車時應每隔一段時間對儀錶進行一次掃視，不要等到發動機熄火了才恍然大悟
2) 防止發動機過熱，應注意平時檢查!
檢查冷卻液應與檢查機油同等對待，虧損時應查明原因，及時補充，平時應做好對散熱器的清潔工作，注意清除附著在散熱器片中間的灰塵和雜物，日常維護時，應及時調整風扇傳動帶的張緊度，認真檢查散熱器蓋閥門、節溫器的工作性能。工作不良時，及時加以更換。

The cooling system is an important "organ" of the engine and if it is not working properly, the engine will become overheated or underheated. Overheating is as bad as the human body, and can often lead to mechanical damage. There are basically three causes of engine overheating: coolant depletion, poorly working radiator components and faulty loop piping.
(1) Overheating of the engine is first reflected by the coolant temperature gauge on the dashboard.
Once the coolant temperature gauge indicator enters the "red zone", you should immediately stop the car to check if it is a coolant loss, accompanied by the coolant alarm light flashing. Therefore, it is important to scan the gauge every so often when driving, rather than waiting until the engine is off before realising it!
2) To prevent the engine from overheating, it is important to check it regularly!
The coolant should be checked in the same way as the oil, and the cause of the loss should be identified and replenished in a timely manner. If they are not working well, replace them in a timely manner.
