How much is the temperature of the water tank most suitable? a wonderful content
To ensure that the engine is operating in the normal temperature range, the car is equipped with an engine coolant temperature sensor, which is usually displayed separately on the car dashboard (water temperature gauge). If the antifreeze temperature is too high, an alarm will occur. In general, the engine water temperature gauge is displayed with a physical or virtual dial pointer, while a few vehicles do not have a dashboard, and only a warning sign appears when the temperature is too high. Whether it is a physical or virtual water temperature meter, the pointer orientation is basically similar, generally with a 60 ° C - 120 ° C dial or Cold (C) - Hot (H) logo. Antifreeze is different from traditional tap water, and its added calcium chloride, organic methanol, ethanol, ethylene glycol, glycerin and other components can work at temperatures above 100 °C.
From the above introduction, we know that the engine coolant temperature is not as low as possible, nor is it as high as possible. It needs to be within a certain range. The normal temperature is 90 °C in the center of the pointer. After the vehicle starts, the temperature of the antifreeze rises rapidly. After the pointer reaches the central position, the temperature of the heat exchange balance antifreeze does not rise any more. Generally, the temperature starts to reach the middle position, which is one of the reasons why the vehicle needs to be hot before starting. .
Water temperature gauge temperature is too high Fault analysis:
In general, the failure of the cooling system mainly includes leakage, insufficient coolant, failure of the cooling fan, and failure of the circulating water pump.
Insufficient liquid leakage and coolant
If the cooling system leaks, it will lead to insufficient antifreeze, which will increase the temperature of the antifreeze. If the antifreeze is found to be low, first check the leak. If you do not need to add the same type of antifreeze in time, do not add tap water or other models. Antifreeze to avoid dilution or even precipitation, resulting in failure or failure.
Cooling fan failure
The failure of the cooling fan will cause heat to be transferred to the antifreeze when the engine is running at high speed, and the heat will not be released in time, resulting in an increase in the temperature of the antifreeze, which may lead to problems such as “opening the pot”. The temperature of the antifreeze must be paid attention to during the driving. When the abnormality is found, first reduce the speed of the vehicle, but do not turn off the fire to check whether the cooling fan or the circulating pump is faulty.
Circulating pump failure
After the pump fails, the water on the heat conduction side of the engine cannot be circulated in time, resulting in a rapid rise in water temperature after the engine is started, a failure of the cooling system, a water temperature alarm, and a phenomenon of “opening the pot”. If it is discovered early and appropriate measures are taken, it will avoid the greater failure loss caused by poor cooling, etc. Therefore, it is necessary to stop and check the fault as soon as possible when the water temperature is too high, the alarm light is on, and the “opening” is observed. Root cause, if necessary, help the repair station to solve.
