The dangers of cooling fan does not turn, mercedes-benz fan is important part of engine cooling system, if the fan does not turn, so the cooling system will not get heat, heat of the engine will continue to rise, a short time, the cooling system of the circulating fluid will appear the phenomenon of water boiled, once the engine overheating, will melt cause failures, such as cylinder piston Let its development, will eventually lead to the engine tile, hold the shaft, ramming cylinder, until the engine scrapped, so encounter this situation shall not be careless.

　　奔馳汽車發(fā)動(dòng)機(jī)水溫高如果保險(xiǎn)絲沒燒的話，就是風(fēng)扇插頭處搭鐵不好，或已燒蝕導(dǎo)致的；將電子扇故障排除后水溫就會正常了。

　　Benz engine water temperature is high if the fuse is not burned, it is the fan plug is not good, or has been ablated; Once the fan is malfunctioned, the water temperature will be normal.

　　如果電動(dòng)冷卻風(fēng)扇在發(fā)動(dòng)機(jī)冷卻液溫度升高到規(guī)定溫度后沒有及時(shí)運(yùn)轉(zhuǎn)，會導(dǎo)致發(fā)動(dòng)機(jī)冷卻液溫度過高，甚至出現(xiàn)水箱開鍋的現(xiàn)象；

　　If the electric cooling fan does not run in time after the engine coolant temperature rises to the specified temperature, the engine coolant temperature will be too high, and even the water tank will boil.

　　對于不同牌號的汽車或同一牌號不同年份生產(chǎn)的汽車，其電動(dòng)冷卻風(fēng)扇的控制電路都不完全相同，因此在檢修電動(dòng)冷卻風(fēng)扇不轉(zhuǎn)的故障時(shí)，應(yīng)參照該車型維修手冊中的內(nèi)容和診斷程序；

　　For cars of different brands or cars produced in different years of the same brand, the control circuit of the electric cooling fan is not exactly the same, so when repairing the failure of the electric cooling fan, the contents and diagnostic procedures in the maintenance manual of this model should be referred to;

　　一般車型的電動(dòng)冷卻風(fēng)扇控制電路的原理。安裝在發(fā)動(dòng)機(jī)水道或散熱器上的冷卻液溫度開關(guān)和汽車空調(diào)開關(guān)，通過繼電器共同控制冷卻風(fēng)扇電機(jī)，在發(fā)動(dòng)機(jī)冷卻液溫度達(dá)到規(guī)定數(shù)值時(shí)或開啟汽車?yán)錃饪照{(diào)時(shí)，電動(dòng)冷卻風(fēng)扇電機(jī)都會運(yùn)轉(zhuǎn)。

　　General model electric cooling fan control circuit principle. The coolant temperature switch installed on the engine channel or radiator and the automobile air conditioner switch jointly control the cooling fan motor through the relay. When the engine coolant temperature reaches the specified value or when the automobile air conditioner is turned on, the electric cooling fan motor will operate.

　　另外，奔馳車輛風(fēng)扇運(yùn)轉(zhuǎn)時(shí)，有輕微抖動(dòng)是正常的。在實(shí)際使用中可能會在散熱器風(fēng)扇上附著一些雜物（柳絮、泥土等），導(dǎo)致風(fēng)扇運(yùn)轉(zhuǎn)時(shí)抖動(dòng)。如果抖動(dòng)比較嚴(yán)重，請及時(shí)到維修處進(jìn)行修理，濟(jì)南奔馳汽車維修哪家好？更多問題請來http://www.junwumy.com咨詢！

　　In addition, Benz vehicle fan operation, a slight jitter is normal. In actual use, there may be some sundries (catkins, soil, etc.) attached to the radiator fan, resulting in the shaking of the fan during operation. If the jitter is serious, please go to the repair place in time to repair, jinan Benz car repair which good? More questions, please http://www.junwumy.com consultation!
