In hot summer, the engine cooling system is prone to failure, which shows that the water temperature is too high and the water temperature indicator reaches the red line, which seriously affects the driving safety.

　　发动机水温高的原因有以下几点:

　　The reasons for the high engine water temperature are as follows:

　　冷却风扇坏了。冷却风扇可由温度开关控制;它也可以由水温传感器控制。济南哪里修奥迪比较两种冷却介质不足。防冻液:高档车要求全年灌装防冻液;(2)水或蒸馏水:临时的;水箱的盖子漏了。

　　The cooling fan is broken. The cooling fan can be controlled by a temperature switch; it can also be controlled by a water temperature sensor. Jinan where repair Audi more professional two cooling medium shortage. Antifreeze: high-end vehicles require filling antifreeze throughout the year; (2) water or distilled water: temporary; the cover of the water tank is leaking.

　　3.恒温器坏了。(1)如果要拆下恒温器，此时应将小的循环塞住，使冷却液能保证全部通过散热器;安装新温控器时，应注意有水孔，如桑塔纳没有水孔，此时应用6mm钻一个孔。一个是标记;另一个作用是汽车在加热过程中，两边的温控器温度差，使温控器随水温准确打开。

　　3. The thermostat is broken. (1) if the thermostat is to be removed, the small circulation should be plugged at this time so that the coolant can pass through the radiator completely; when installing the new thermostat, attention should be paid to the existence of water holes. If there is no water hole in Santana, a hole of 6mm should be drilled at this time. One is the mark; the other is the temperature difference between the temperature controllers on both sides of the car during the heating process, so that the temperature controller can be opened accurately with the water temperature.

　　四。水槽堵塞。(1)外插水或气，污垢;内部的堵塞会影响冷却剂的循环，并会产生压力，会有两种结果，一是水箱泄漏，另一种是在水温特别高的时候高速运行。

　　Four. The sink is clogged. (1) insert water or air outside to remove the dirt; the internal blockage will affect the circulation of coolant and generate pressure. There are two results, one is the leakage of water tank, the other is the high-speed operation when the water temperature is particularly high.

　　五个泵坏了。叶轮打滑或卡死，造成正时皮带断裂;(2)叶轮变形。

　　Five pumps are broken. The impeller slips or gets stuck, causing the timing belt to break; (2) the impeller is deformed.

　　六。汽缸侵蚀。(1)燃烧室和水渠冲洗后，再从排水管排出或白烟，造成水箱经常缺水;(2)水道与油路钝(油有水白);(3)水槽和水槽，导致缸体散热不良，特别是在高速时冲击较大;(4)阻塞水道。

　　Six. Cylinder erosion. (1) after the combustion chamber and water channel are flushed, they will be discharged from the drain pipe or white smoke, which will cause water shortage in the water tank; (2) the water channel and oil channel are blunt (oil has white water); (3) the water channel and water channel lead to poor heat dissipation of the cylinder block, especially in case of high-speed impact; (4) the water channel is blocked.

　　七。点火正时不正确(使用正时灯校正)和油压过高。

　　Seven. Incorrect ignition timing (corrected with timing light) and high oil pressure.
