The water temperature has been normal, the water temperature meter shows normal, but the water tempe

It should reach 50 degrees after a few minutes of starting, but the water temperature of the engine should be maintained at about 85-90 degrees Celsius in the best condition, and generally speaking, the water temperature should reach the normal temperature after about 10 minutes of driving after stable idling. It is related to the ambient temperature, and the temperature is low and the hot car takes a little longer. But if it's 50 degrees all the time, I guess there's something wrong with the thermostat.

100 degrees will not boil the pot, now the vast majority of antifreeze is added, the boiling point is basically above 120 degrees!!

The most suitable temperature for normal is 90. When the engine has just started and the water temperature is low, the thermostat in the tank is turned off to allow the water channel to circulate for rapid heating. After the temperature rises to more than 60 degrees, as the water temperature rises, the thermostat slowly opens, thus opening the large circulation.

When the circulation is turned on, the water temperature gradually rises to 90 degrees. The cooling system is equipped with an inductor, and when the temperature is more than 80 degrees Celsius (different models are designed), the fan of the water tank starts to operate to keep the temperature at 90 degrees. When the temperature falls below the critical value, the fan is turned off and the water temperature rises again.

Repeatedly, the tank temperature is kept in the 90-degree range.

The temperature of 90 degrees is based on the data of so many years of practical experience and experiments, and at this temperature, the mechanical properties of the engine are optimal. If the temperature is too low, it will lead to the following:

1) Too low temperature can make the combustible mixture difficult to ignite or slow combustion, resulting in a decrease in engine power and an increase in fuel consumption.

2) The viscosity of the lubricating oil increases, and it cannot enter the gap of the moving parts, which aggravates the wear of the parts and increases the power consumption.

3) The oil film on the friction surface (cylinder wall, piston, piston ring, etc.) is washed by the unvaporized fuel due to too low temperature, and the lubricating oil is diluted, which aggravates the wear of parts.

The consequences are even worse if the temperature is too high:

1) If the cylinder wall temperature is too high, it will destroy the lubricating oil film of the cylinder wall, reduce the lubrication performance and accelerate the wear of the parts.

2) The piston ring in the cylinder expands due to high temperature, which destroys the fitting clearance, resulting in an increase in frictional resistance, and in severe cases, the phenomenon of seizure may occur. (commonly known as bursting cylinder).

3) The possibility of pre-ignition and deflagration increases, which destroys the normal operation of the engine; At the same time, it also causes the parts to be subjected to additional shock loads that can cause early damage.

If the temperature is too high and the pot is boiled (white smoke from the engine, commonly known as boiling), it can only be dragged to the repair shop for overhaul. Therefore, when driving, you must pay attention to the water temperature and the oil alarm.

Hope mine can help you.

There are several reasons why the water temperature is too high:

1. The water tank is not well dissipated, and the water tank will be blocked by dust after working for a long time.

Second, the cylinder gasket is damaged, and the high air pressure of the combustion chamber will flow into the heat dissipation water channel, and there will be high temperature at this time, which can be solved by replacing the cylinder gasket.

3. Lack of cooling water, which will cause poor heat dissipation, add cooling water, the specific operation steps are as follows:

1. Open the driver's door.

2. Pull the hood switch.

3. Lift the hood of the engine.

4. Slowly unscrew the lid of the small kettle of the water tank and release the internal high-pressure gas.

5. Fill the small kettle with cooling water to max.

Notes:1. Wait until the engine is cool before opening the water filler cover.

2. The added cooling water should have the same specifications.

While driving, we must always pay attention to the health of the vehicle. When white smoke comes out of the hood of the vehicle, we have to stop and check. So, what is the problem of white smoke and burnt smell from the hood of a car?

I think the lack of antifreeze in the engine, the short circuit draft, and the failure of the water tank cooling refrigerator fan will basically make the engine compartment smoke.

What's wrong with white smoke and the smell of burnt on a car's hood?

1.The engine lacks antifreeze. When the engine lacks antifreeze, the engine can easily cause high temperatures, and when the temperature is high, the engine will emit white smoke. In this case, we need to stop on the side of the road immediately and add the right amount of antifreeze;

2.The line is short-circuited. I think there are a lot of lines in the cabin. If these lines are short-circuited, there will be white smoke. At this point, we should pull over and wait for the tow truck to rescue.

3.The radiator fan of the tank is malfunctioning. Damage to the fan can affect the high temperature of the tank. At this time, the water tank is easy to leak and accompany the wheel. When antifreeze comes into contact with a hotter engine, white smoke is emitted.

Why does the water temperature gauge emit white smoke during normal hours?

I don't think the reason for the white smoke in the engine compartment is necessarily the high water temperature. Sometimes the wiring is short-circuited and the engine rubber melts, which basically affects a similar situation.

Secondly, if the water temperature sensor fails, the water temperature gauge will always be in its normal position, but by this time the water temperature is already too high, affecting the white smoke coming out of the cabin. In other words, there are many causes of white smoke from the engine compartment, and countermeasures need to be taken according to the actual situation.

Millions of car purchase subsidies.

The reason why the water temperature has not come up is that the thermostat is damaged or the cooling fan is often rotated, and the thermostat is running to adjust the water temperature. For electronic fans, circuit failures cause the electronic fans to rotate constantly, and for silicone oil fans, damage to the silicone oil clutch will also cause the fan to rotate constantly, and these faults will produce low water temperatures. The solution to the high water temperature in the car is:

1. Park the car on the side of the road; 2. Cover the water tank cover with a damp cloth folded many times, unscrew a small slit in the water tank cover, and let the water vapor slowly discharge; 3. Observe the water temperature gauge of the dashboard, and add cold water or antifreeze after the pressure of the sock water tank drops.

The reasons for the increase in the water temperature of the car are: insufficient coolant, leaking water in the water tank, failure of the cooling fan, and failure of the water pump.

1. Insufficient coolant

When the engine is working, the long-term water circulation will cause the loss of coolant from the engine cooling system, resulting in a shortage of water in the water tank.

2. The water tank is leaking

Broken or poorly connected water pipes in the tank connection can cause water leakage.

3. The cooling fan is faulty

If the cooling fan is damaged or the wiring is short-circuited, the fan works or the cooling fan rotates slowly, which will cause the heat of the engine to not be dissipated, and the water temperature of the engine will naturally rise.

4. The pump is faulty

When the pump fails, the water that conducts heat to the engine cannot be circulated and renewed in time, so the water temperature will rise rapidly after the engine starts.

How to deal with the water temperature of the car is too high

1. If you find that the water temperature of the car is too high, stop the car first, and then put warning signs on the front and back of the car, and then start to deal with the problem of high water temperature.

2. Don't turn off the engine immediately, let the engine continue to work for a while, turn on the air conditioner to the maximum, open the front cover, speed up the heat dissipation, and turn off the engine when the temperature drops.

3. Check whether the coolant in the water tank is below the standard line, if it is too low, add coolant in time, if not, you can also use water for emergency use, and add it in time after there is coolant.

4. Check whether the water tank, water pipe and other accessories are leaking. Check if there is a problem with the fan, and see if the fan can turn on automatically when the car is idling, if not, it is likely that there is something wrong with the fan.

1. Insufficient coolant

Coolant leakage or lack of coolant will cause the engine water temperature to rise, then we should check the coolant situation, if the deficiency is added to the appropriate place first, and then after a few days to check if the fluid level is seriously dropped, if so, then we need to find the leak location.

2. The cooling fan is faulty.

If the cooling fan fails, the heat generated by the vehicle cannot be transferred to the antifreeze in time when the vehicle is running at high speed, which will affect the heat dissipation, and then cause the temperature of the antifreeze to rise, resulting in problems such as boiling the pot.

3. Circulating water pump failure.

Water pump failure has several situations of bearing locking and impeller damage, bearing locking is relatively rare, impeller damage is common after impeller cracking or impeller loosening from the pump shaft, resulting in coolant circulation speed slowdown, easy to cause engine temperature too high failure.

4. Thermostat failure.

The function of the thermostat is to automatically adjust the amount of water entering the radiator according to the temperature of the cooling water, and change the circulation range of the water to adjust the heat dissipation capacity of the cooling system and ensure that the engine works within the appropriate temperature range. If the thermostat fails, then the car's cooling system may not be able to circulate largely, causing the water temperature to rise.

5. Poor heat dissipation of the water tank.

I believe that some car owners have tried to use water as coolant, once or twice is no big problem, remember to clean the cooling system and replace it with coolant, if you use water for a long time to do ** will cause rust in the engine and water tank, poor heat dissipation of the water tank leads to high water temperature.

Hope, thank you!

1. First of all, after finding that the water temperature is too high and stopping to the side, it should not be turned off immediately, because there are many reasons for the high water temperature, but there is probably only one fault each time, if all other functions are turned off, the water temperature will be too high, damaging the engine, the accurate approach should be to idle the park, open the hood, turn on the heater, dissipate heat as soon as possible, and pay attention to parking in a cool place. 2. Next, we have to check whether the coolant is sufficient, this situation is likely to be that the owner usually does not care about forgetting to add it in time, and it should be noted that the owner must choose the same brand and model of product when adding coolant, otherwise it may cause chemical reaction due to different components and lead to the failure of antifreeze. 3. Then, we are looking at whether the cooling fan is running normally, and the failure of the cooling fan will cause the heat generated in the car engine to be transferred to the antifreeze at high running speeds and not get timely heat dissipation, resulting in an increase in the temperature of the antifreeze.

If the fan is stuck or the insurance is burned, you can solve it as soon as possible after the power failure, if it is a line problem, it can only be handed over to the professionals of the 4S shop to overhaul. Extended Information:Car Radiator Function:

The function of the cooling system is to dissipate excess and useless heat from the engine, so that the engine can operate at normal temperature at all speeds or driving conditions.

The water tank is the heat exchanger of a water-cooled engine, which is cooled by air convection to maintain the normal operating temperature of the engine. Once the engine cooling water in the water tank boils and vaporizes and expands due to high temperature, and the pressure exceeds the set value, the pressure is discharged from the water tank cover (a), which causes the cooling water to decrease and prevent the cooling system line from bursting.

When driving, you should pay attention to whether the engine cooling water temperature gauge pointer on the dashboard is normal. In addition, if the engine cooling fan fails and the engine cooling water temperature rises or the cooling system pipeline leaks, the cooling water may also be reduced.

The reasons for the high water temperature are generally: 1. The coolant is insufficient, when the engine is working, the long-term water circulation will cause the coolant loss of the engine cooling system, resulting in the lack of water in the water tank. 2. Water leakage in the water tank, broken or loose connection of the water pipe connecting the water tank will cause water leakage; 3. The cooling fan is faulty, the cooling fan is damaged or the wire is short-circuited, which causes the fan to work or the cooling fan speed is slow, which will cause the heat of the engine to be unable to dissipate, and the water temperature of the engine will naturally rise; 4. The water pump fails, after the pump fails, the water of the engine heat conduction can not be circulated and updated in time, and the water temperature will rise rapidly after the engine starts.

How to check. Kiss <>

The water temperature gauge is red, and it is a faulty engine cooling system.

But the water temperature is not high, showing 90 degrees.

Kiss <>

The water temperature was not high, and the water temperature gauge suddenly showed red and suddenly sounded. There are many reasons to rule out.

Kiss <>

When the water temperature gauge shows red and makes a dripping sound, immediately stop and check the cooling system of the vehicle to see if the coolant is sufficient, whether the radiator is blocked, whether the water pump and heat exchanger are working properly, and hold and replace the parts that need rubber crack repair in time. Avoid driving in high temperatures, so as not to cause damage to the engine and close the beams.

I'm still driving, and the water temperature isn't high.

Expansion: Automobile water temperature gauge refers to the instrument used to measure the temperature of automobile engine coolant, which is subject to the unit of measurement Feng and the degree of silver volt. The scale of the car water temperature meter ranges from C to H to H, and the water temperature fluctuates between C and H under normal circumstances.

H: If the engine is overheated, stop and shut down the engine immediately, and wait for it to cool down before checking and repairing.
