五菱鸿途水箱风扇不转和水温高

水温传感器已经更换,同时电脑版也与同型号汽车对换,散热器风扇继电器电路正常 ,水温传感器线路与电脑版线路正常,诊断仪读取发动机水温数据正常,诊断仪水温数据达到97度,风扇依然不转,用搭铁信号触发风扇继电器,可以实现风扇运转。请问还有什么原因会引起风扇不转,水温过高呢?
发英文的哥们!我在问汽车的问题,你回答篮球问题就不对了吧?就算你英语水平高,也不能我问你上厕所了没,你回答你刚刚吃过饭了,那也太不地道了吧?

  发动机水温高主要是因为保险丝没烧的话,就是风扇插头处搭铁不好,或已烧蚀导致的。将电子扇故障排除后水温就会正常了。
  如果电动冷却风扇在发动机冷却液温度升高到规定温度后没有及时运转,会导致发动机冷却液温度过高,甚至出现水箱开锅的现象。对于不同牌号的汽车或同一牌号不同年份生产的汽车,其电动冷却风扇的控制电路都不完全相同,因此在检修电动冷却风扇不转的故障时,应参照该车型维修手册中的内容和诊断程序。一般车型的电动冷却风扇控制电路的原理。安装在发动机水道或散热器上的冷却液温度开关和汽车空调开关,通过继电器共同控制冷却风扇电机,在发动机冷却液温度达到规定数值时或开启汽车冷气空调时,电动冷却风扇电机都会运转。若发动机冷却液温度升高后,电动冷却风扇没有运转,其原因可能是风扇电机的故障,也可能是继电器、冷却液温度开关或电路方面的故障,可按下述步骤进行诊断:
  (1)找到电动冷却风扇继电器,将继电器拔下,用试灯检查继电器插座上触点电源的插孔上有无12V电源。如果没有电源,应检查电源熔断丝或检修电源线路。若有电源,可用一条电线将继电器插座上触点的两个插孔短接,同时察看电动冷却风扇有无运转,如果没有运转,则可能是风扇电机有故障,也可能是继电器到风扇电机的线路或风扇电机的搭铁线有故障。
  (2)打开点火开关后,用试灯检查继电器插座上接继电器线圈的插孔上有无电流,如没有电流,应检查点火开关到继电器插座的线路。
  (3)安装好电动冷却风扇继电器,将冷却液温度开关上的线束插头拔下,打开点火开关后将冷却液温度开关的接线搭铁(如果插头内只有一个插孔)或将线束插头内的两个插孔短接,如果此时风扇有运转,说明继电器及风扇电机是正常的,冷却液温度升高后,电动冷却风扇没有运转的原因是冷却液。度开关有故障,应更换冷却液温度开关。
  (4)如果在步骤((3)中风扇没有运转,应检查继电器,如果继电器是正常的,则继电器到冷却液温度开关的线路有断路,应检修。

The failure reasons combining magic is not above three:

One cannot play, Howard, Magic playoffs can win powerful knights and Celtic last key moments, the third play a role, but three points this point will open, must depend on the inside. Howard, The first two games and series,wholesale NFL jerseys, Howard rarely injuriously inside. We know that without the ball back body attack Howard, but the celtics in the first daring choice doubled-teamed others, Howard inside the ball or kendrick perkins singles Kevin garnett. The first 2 day, with strong perkins, Howard't. Howard's advantage lies in fact do wall screen after the attack, facing the basket as much magic against lob gave him, Howard can bomb,Authentic NHL jerseys, green basket to doubled-teamed Howard, exterior space is opened.

Second, the defensive. Compared with the magic defensive system was - terk case lu, this is not good at marker Vince carter became the biggest vulnerability. Especially big fan decided to use "tian racing," choose carter defensive ability of singles stronger after Paul Pierce, magic lines became a sieve. In the first scene to Pierce made six of eight carter scored 23 points in game 2, try to 28 points. Until the third field, big FanCai decided to change the defense,NBA Jerseys, matt - defensive Pierce, though Mr Barnes was to Pierce the only 15 points, but it will be too late.

Third, not seize their physical advantages. The celtics played champions defense, they eliminated knight, continuous smothered the magic three games. But after the celtics a team player, the more physical problem. Don't even say the magic before 2 series are almost is swept well-rested. But the magic can't carry the advantage in the game, but lost their strengths in Boston.

Magic has hit the running, Howard is in the center of the body and the movement is with the force of ". If they can play their offense round number, can increase the energy consumption of green army. But big fan in the layout is but positional warfare, but slower pace, it falls into a green defense system, not a physical problem with the celtics natural defense to seal the magic. Magic game had 11 points and fast celtics have eight points, it is the biggest tactics fail. Magic

These three, summarizes up only in a big fan, operational command, so the slow. If mourinho knows he is basketball, kosalans magic may have more champions temperament. Actually this magic and inter configuration is very similar to each player,The commander cheap jerseys was looking for him, but are not very strong ability of temper, they will be bidding for strong coach jose mourinho that coach can inspire them to fight!

我的车型和你的一样,也是鸿途,前段时间也高温,修了4次才修好,说的是水箱里面有气,导致循环不好,水箱里面是凉的但是发动机机体里面是热的。恭喜你的帖子被我看到本回答被提问者和网友采纳

你发动车,等到水温上升到97度时,用手摸摸水箱上水管和下水管(注意带手套),如果有很明显的温差,估计就是节温器坏了。风扇不转的原因有很多,例如,水箱使用久了,杂质过多导致循环不畅,或是水箱里面有空气没有完全排出等等。车载日常的使用中,也要经常地检查水位油位啊。自己搞不定的话送附近修理厂吧。

一般不会吧。
