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.

　　發(fā)動機水溫高的原因有以下幾點:

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

　　冷卻風扇壞了。冷卻風扇可由溫度開關(guān)控制;它也可以由水溫傳感器控制。濟南哪里修奧迪比較兩種冷卻介質(zhì)不足。防凍液:高檔車要求全年灌裝防凍液;(2)水或蒸餾水:臨時的;水箱的蓋子漏了。

　　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.恒溫器壞了。(1)如果要拆下恒溫器，此時應將小的循環(huán)塞住，使冷卻液能保證全部通過散熱器;安裝新溫控器時，應注意有水孔，如桑塔納沒有水孔，此時應用6mm鉆一個孔。一個是標記;另一個作用是汽車在加熱過程中，兩邊的溫控器溫度差，使溫控器隨水溫準確打開。

　　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)外插水或氣，清除污垢;內(nèi)部的堵塞會影響冷卻劑的循環(huán)，并會產(chǎn)生壓力，會有兩種結(jié)果，一是水箱泄漏，另一種是在水溫特別高的時候高速運行。

　　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.

　　五個泵壞了。葉輪打滑或卡死，造成正時皮帶斷裂;(2)葉輪變形。

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

　　六。汽缸侵蝕。(1)燃燒室和水渠沖洗后，再從排水管排出或白煙，造成水箱經(jīng)常缺水;(2)水道與油路鈍(油有水白);(3)水槽和水槽，導致缸體散熱不良，特別是在高速時沖擊較大;(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。點火正時不正確(使用正時燈校正)和油壓過高。

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