奥迪汽车维修千万不能图便宜

来源:http://www.jnrunao.com/ 日期:2021-11-05 发布人:runao
正常情况下,发动机都配置有很多传感器,当发动机出现故障时,除了极少数的皮带、机脚等机械类故障无法被传感器监测外,大部分零件在出现故障后,会以故障灯亮起的方式在仪表显示,提醒车主及时检查维修。
Under normal circumstances, the engine is equipped with many sensors. When the engine fails, except for a few mechanical faults such as belt and machine feet that cannot be monitored by the sensors, most parts will be displayed on the instrument in the way of fault light, reminding the owner to check and repair in time.
这不,一辆奥迪的仪表就亮起了发动机的故障灯,车主在发现后直接把车开到修理厂检查。我们的师傅也很给力,很快就找出故障位置,并给了车主维修建议。之后,车主自己买了配件,今天拿来让师傅更换。
No, an Audi instrument lights up the engine fault light. After discovering it, the owner directly drives the car to the repair shop for inspection. Our master also gave awesome energy, and soon found out the location of the trouble and gave the car owner maintenance advice. After that, the owner bought the parts himself and asked the master to replace them today.
当车主看到拆下的故障零件后,暗自庆幸,幸好及时来检查维修,若是不维修的话,发动机很容易就会出现高温的问题,后果很严重。
When the owner saw the removed faulty parts, he was thankful that he came to inspect and repair them in time. If they were not repaired, the engine would easily have the problem of high temperature, and the consequences would be very serious.
据师傅介绍,这辆奥迪检测出来的故障如下图绿色区域所示:节温器在打开的状态下卡住,冷却液温度上升过慢。我们先了解一下节温器的常识:大部分节温器是石蜡类型,作用是调节发动机冷却液大小循环,发动机水温低的时候,它是关闭状态,冷却液小循环,让发动机快速升温;水温高后,它会打开,冷却液经过水箱进行大循环。
According to the master, the fault detected by this Audi is shown in the green area below: the thermostat is stuck when it is open, and the coolant temperature rises too slowly. Let's first understand the common sense of thermostat: most thermostats are paraffin type, which is used to adjust the large and small circulation of engine coolant. When the engine water temperature is low, it is closed and the coolant circulates for a small circulation, so that the engine can heat up quickly; When the water temperature is high, it will open and the coolant will circulate through the water tank.
根据上面的提示,我们就可以得出结论:节温器无法正常打开,冷却液不能进行大循环!如果不维修的话,发动机的冷却液温度会过高,不能通过水箱散热,很容易高温。师傅给车主的维修建议就是更换节温器,车主知道后,自己买来了节温器。下图所示,这就是车主自己买来的节温器,小编看了价格,很便宜。
According to the above tips, we can draw a conclusion: the thermostat cannot be opened normally and the coolant cannot be circulated! If it is not repaired, the coolant temperature of the engine will be too high and can not be dissipated through the water tank, which is easy to be high. The maintenance advice given by the master to the owner is to replace the thermostat. After the owner knew it, he bought the thermostat himself. As shown in the figure below, this is the thermostat bought by the owner. Xiaobian looked at the price and it was very cheap.
既然有了配件,那就开始拆卸节温器。维修的步是放出冷却液,由于冷却液是车主刚换不久,所以师傅用一个盆子把放出的冷却液收集起来。然后就要进行了如下图所示的步骤:拆下发电机皮带。绿色箭头所示,节温器在这个位置。
Now that you have accessories, start removing the thermostat. The first step of maintenance is to drain the coolant. Since the coolant has just been changed by the owner, the master uses a basin to collect the discharged coolant. Then proceed to the steps shown in the figure below: remove the generator belt. The green arrow shows that the thermostat is in this position.
下图箭头所示,师傅已经把旧节温器给拆了下来,我们可以看出水道里面很干净。
As shown by the arrow in the figure below, the master has removed the old thermostat. We can see that the water channel is very clean.
下图所示,这就是拆下来的旧节温器,箭头所示的位置可以随温度变化。奥迪车主看到旧节温器后,一时发现不了问题,就问师傅:节温器是哪里的问题呢?
As shown in the figure below, this is the removed old thermostat. The position shown by the arrow can change with the temperature. After seeing the old thermostat, the Audi owner couldn't find the problem for a moment, so he asked the master: where is the problem with the thermostat?
师傅拿着旧节温器,指着下图绿色箭头所示的位置,对车主表示就是这个位置会卡住。我们可以看出这个位置有很明显被摩擦的痕迹,车主在看到这样的情况后,立刻就明白了!没想到这不起眼的故障竟然是节温器卡住了,幸好这次及时维修。
The master took the old thermostat and pointed to the position shown by the green arrow in the figure below. He told the owner that this position would get stuck. We can see that there are obvious signs of friction in this position. After seeing this situation, the owner immediately understood it! I didn't expect that this insignificant fault was that the thermostat was stuck. Fortunately, it was repaired in time this time.
半个小时左右,师傅就安装好节温器,然后就要安装发电机皮带。下图所示,师傅正在安装发电机皮带,箭头所示的工具是固定皮带涨紧器到更小位置,这样就能拆卸和安装皮带。
In about half an hour, the master will install the thermostat, and then install the generator belt. As shown in the figure below, the master is installing the generator belt. The tool shown by the arrow is to fix the belt tensioner to the minimum position, so that the belt can be removed and installed.
发动机皮带被安装好之后,需要添加冷却液,并启动发动机检查。然而,当师傅启动发动机后,皮带又传来了叽叽的异响,这就需要师傅进一步检查。下图橙色区域所示,师傅正在用检查异响的听诊器来确定异响位置,主要检查的就是1涨紧器,以及2和3所示的惰轮,又叫过桥轮。
After the engine belt is installed, add coolant and start the engine for inspection. However, when the master started the engine, there was a creaking noise from the belt, which required further inspection by the master. As shown in the orange area below, the master is using the stethoscope to check the abnormal sound to determine the abnormal sound position. The main inspection is 1 tensioner and the idler gears shown in 2 and 3, also known as bridge pulley.
下图所示,这是小编在车下面拍的情况,师傅检查节温器位置不漏水,安装完好。红色的123分别对应上图绿色的123,异响的位置是2和3所示的惰轮,需要更换。
As shown in the figure below, this is the picture taken by Xiaobian under the car. The master checked that the thermostat position was watertight and installed well. The red 123 corresponds to the green 123 in the above figure respectively. The position of abnormal noise is the idler gear shown in 2 and 3, which needs to be replaced.
师傅又询问奥迪车主得知,车主上次只换了发电机皮带和涨紧轮,没有换这两个惰轮,因为当时这两个惰轮没有异响。这下,师傅就批评车主,像这样的皮带套装,更换一次就要全部更换,因为它们设计的寿命差不多,虽然更换套装时有些零件没坏。幸好这辆奥迪的惰轮容易更换,不然车主又要花很多钱来维修。这点需要广大车友注意!
The master asked the Audi owner and learned that the owner only changed the generator belt and tensioning wheel last time, but did not change the two idlers, because there was no abnormal noise at that time. At this time, the master criticized the owner. For belt sets like this, they should be replaced once, because their design life is similar, although some parts are not broken when replacing the set. Fortunately, the idle wheel of this Audi is easy to replace, otherwise the owner will have to spend a lot of money to repair it. This needs the attention of the majority of riders!

,师傅在车上踩油门让发动机水温快速上升,一直等到节温器打开,并且电子扇转动才算是维修结束。车主对于维修结果很是满意,并表示会尽快更换在维修中检查出的两个惰轮。车友可以简单了解一下这个维修案例,在爱车出现问题后,应该及时检查问题,及时消除故障隐患,不要不好意思检查,检查一般都是不收费。
Finally, the master stepped on the accelerator to make the engine water temperature rise rapidly. The maintenance was not completed until the thermostat was opened and the electronic fan was turned. The owner was very satisfied with the maintenance results and said that he would replace the two idler gears found in the maintenance as soon as possible. Car users can simply understand this maintenance case. After a problem occurs in their car, they should check the problem in time and eliminate the hidden trouble in time. Don't be embarrassed to check. Generally, there is no charge for inspection.
