Many old drivers drove for a long time，But I don’t necessarily understand the water thermometer。When the seabet appwater temperature is high，It's a bit nervous，Worried about the engine for opening the pan。On the contrary, when the water temperature is low，But don't take it for granted。Is this right?

The normal water temperature of the general car will be around 90 degrees (of course, different brands of cars are different)，The water temperature meter that clearly mark the temperature value can be clearly seen at the instant water temperature，But some water temperature meters only have scales without value display。The normal temperature should be about 90 ° C。Once too high or too low，Or quickly rise or decrease。That is all problems。
Usually when the water temperature is normal, the pointer will refer to the middle location of the water temperature meter (different models are different，It is recommended to check the warranty manual)，However, there will be a red area on the right side of the water thermometer to indicate a high temperature area，Pay attention when the pointer is close to this area，Explain that the seabet appwater temperature is high，During the driving process (especially in summer), the water tank temperature is too high or even "open the pot"，But when it is found that the water temperature is too high，Emergency method should be taken，Can't drive forcibly，Otherwise, it will cause great damage to mobilization。
and if the water temperature of the car engine is low, the hazard is very high，It will make the mixed gas burning insufficient，Decrease power，Add，and cause poor lubrication，It will also cause excessive emissions。
If the temperature is too high, it may be caused by the following reasons!

Cooling liquid leak will cause its temperature to rise。At this time, check whether the coolant is leaked! If there is，So you should quickly repair the leaky pipe。If not，The coolant of the same brand should be added in time! It is not recommended to add water, especially winter，Even if it does not cause a failure，It will also have a diluted effect on the coolant!

Sprinkle hot fan will cause，When the vehicle is high -speed operation，generates heat and cannot be passed to the anti -freezing fluid in time to affect the heat dissipation，and then cause the temperature of the antifreeze to rise，Cause problems such as opening the pan! this circumstance occurs，If during driving,，Reduce the speed first。Check whether it is the problem of the fan，If it is，Repair in time，Don't wait for the pan to repair it!

Once the pump happens，The water cycle on the engine heat conduction side cannot be performed normally。Causes the engine cooling system to fail，"Open the pot" phenomenon will cause it! Be sure to discover it early，Solution early。General water pump problems，seabet appIt may be a bearing to die or the louver is damaged! The possibility of shaving is not likely。The shutters are broken!
The main reasons for the low water temperature are as follows:
The cause of the water temperature of the engine is too low, which is generally the damage to the thermostat or the heat dissipation fan is often transferred。

The thermostat is based on the water temperature of the engine，Components that automatically play a valve function，Generally installed on the exit of the radiator，The import of the pump。When the temperature of the coolant is low，The thermostat blocks the low temperature cooling water from the radiator，Make it unable to enter the engine water cover，The water temperature in the water cover can rise quickly，is a small cycle that everyone often refers to。
If the water temperature rises to a certain temperature，Valve gradually open，The coolant in the radiator starts to circulate again，Make the cooling fluid flowing through the radiator，Start slowly to rise slowly，Heat the atmosphere through the radiator，Keep the engine water temperature at the right temperature，This is a large cycle。
If the temperature vessel fails，The valve cannot be closed，Cooling is always in a large cycle，The water temperature of the engine may be too low。or some cars have removed the temperature vessel in order to reduce the temperature when the seabet appwater temperature is high，So the water temperature of the engine will also be very low。　　

There is also a cooling fan。For an electronic fan，Circuit failure causes the electronic fan to rotate regularly; for the silicone oil fan，Damage of silicone oil clutch can also cause the fan to rotate frequently。These faults will cause low water temperature。
