What to do if the water temperature is high in FAW Jiabao, and how to solve the high water temperatu

The function of the cooling system is to keep the engine working in the most favorable temperature range, so as to increase the power of the engine and reduce engine wear and fuel consumption. Practice has proved that too high or too low temperature will have a detrimental effect on the operation of the engine. According to the indication of the water temperature gauge, it is often possible to accurately determine the fault of the cooling system.

If the car is running, the water temperature gauge indicates that it will soon reach the position of 100; Or when the cold car starts, the engine water temperature rises rapidly to boiling, and turns to normal after replenishing the cooling water, but the engine power decreases significantly. Most of the reasons for this type of failure are: serious water leakage in the cooling system; The cylinder gasket is broken, and the water jacket communicates with the cylinder; The main valve of the thermostat falls off; Loose or broken fan belts; The pump shaft and impeller are loose; The fan clutch is working poorly.

The methods for diagnosing and ruling out high engine temperatures are as follows:

1. If the engine suddenly overheats during operation, you should first pay attention to the dynamics of the ammeter. If the ammeter does not indicate charging when increasing the throttle, the pointer only swings back to the "0" position intermittently by discharging 3A 5A, which means that the fan belt is broken. If the ammeter indicates charging, the engine should be turned off, touch the radiator and the engine with your hands, if the engine temperature is too high and the radiator temperature is low, it means that the water pump shaft and impeller are loose, so that the cooling water circulation is interrupted; If there is not much difference between the engine and radiator temperatures, you should look for serious water leaks in the cooling system.

2. The temperature of the cooling water rises to boiling soon after starting, and the main valve of the thermostat falls off and is horizontal in the radiator water inlet pipe, which hinders the large circulation of cooling water. Because this fault can make the pressure in the cooling system rise rapidly, when the internal pressure reaches a certain level, it will suddenly rush open the blocked main valve, make it change its orientation, and quickly conduct the large circulation water path, and the boiling water will break open the cover at this time. If the cooling water is found to be boiling during driving, it should be stopped immediately, so that the engine can run at low speed until the water temperature is normal, and then turn off the engine for inspection, and it is absolutely not allowed to mix water to cool down, so as to prevent the temperature difference from changing too much and causing cracks to increase the internal stress of the relevant parts.

3. The cylinder gasket burns out, and sometimes it can also make the water tank overflow and discharge bubbles, showing the state of boiling cooling water. This is mainly due to the burning of the cylinder head gasket or the crack of the cylinder head and cylinder liner, which causes high-pressure gas to enter the water jacket and bubble out. If a crack in the cylinder head gasket or cylinder head communicates with the lubricating oil circuit, oil stains will also appear in the tank.

The tail number of the mobile phone is 3287 According to what you said, it is possible that the electronic fan is not working properly. Or there is a leak in the coolant, and the sensor should also be checked.

Is it solved? I have one in my hand right now, and it's the same situation as you said.

1. There are many reasons for the high water temperature of the engine or even "boiling", such as damage to the electronic components of the cooling system (thermostat, cooling fan), poor heat dissipation of the radiator, insufficient coolant, etc.

2. Pull over, but don't turn off the engine immediately! Because the coolant temperature is already high and the cooling capacity has reached its limit, if the engine is turned off immediately, the boiling coolant will stop circulating (for most engines, the water pump is driven by the crankshaft).

3. Of course, if it is an electric water pump engine, it will be better), too high temperature can not be cooled, and the engine is also unbearable. If the engine is left idle for a while, the constant circulation of coolant can still reduce the impact of high temperatures on the engine.

4. Check whether the antifreeze is lacking, resulting in high engine water temperature. The circulation of the coolant, whether the circulation is not smooth. Secondly, you can also check that water temperature sensors, water pumps, thermostats, cooling fans, etc., may cause high water temperatures.

If you don't have a strong hands-on ability, you should go to the repair shop for an inspection.

1. Instrument or instrument line failure...

2. Is it LCD or the old model is indicated by the pointer?。。 Judging separately ...

And is it with the instrument assembly or sub-assembly...

Mainly to detect sensor classes, assemblies or sub-assembly lines, instruments and related lines and sensors...

3. Use a detector to detect the normal water temperature to see if it is normal, if it is normal, the ECU control circuit should be fine, if it is not normal, then the ECU related feedback line, temperature control, etc. should also be checked.

4. The possibility of other parts is not ruled out. . .

If the water temperature gauge doesn't show up, check to see if there's a problem with the sensor or if the dashboard itself is faulty.

If the water temperature meter does not display, it may be that the sensor of the dashboard is faulty, or there may be a problem with the line that displays the water temperature, or it is an open circuit.

The situation you are talking about should be that the water temperature gauge sensor is faulty, and it is recommended to check it.
