The water temperature of the car can heat up in a few minutes, why does the water temperature no lon

When driving or idling for a few minutes, the temperature can be quickly raised. The reason why the water temperature does not rise much after driving for a long time is due to the water cooling system of the car's engine.

The water temperature of the car can be heated up in about 5 minutes, and the water temperature will be maintained at a certain temperature after driving for a long time, which is conducive to the normal operation of various parts of the car.

For about 10 minutes, because there is coolant in the car, after reaching a certain temperature, they cannot be raised, and if the coolant is insufficient, the water temperature will become higher and higher.

The water temperature can rise to 80-90 for a short time after the car is started, but it will not continue to rise after a long drive. That's the basic function of a car's cooling system: to keep the engine running at the right temperature at all times.

The engine is also known as the internal combustion engine. The mixture is burned in the cylinder** and the work is done to promote the reciprocating motion of the piston, so the temperature of the combustion chamber is very high. If the heat is not dissipated in time, the engine will be affected by the high temperature.

Most engines use a water-cooled system as shown in the diagram below: there are cooling water channels around the cylinder block, which are filled with coolant and can absorb heat from the cylinders in time. The principle is like burning a boiler.

The engine is equivalent to a furnace, and the cooling water channels around the cylinders and cylinder head are like the water jackets of the boiler

After the temperature in the cylinder is absorbed by the coolant, the coolant should dissipate heat in time to cool the engine, so the coolant after heating flows into the radiator in front of the vehicle under the action of the water pump. Coolant is injected from above the radiator and dissipates most of the heat as it flows to the bottom of the radiator. The coolant with reduced temperature returns to the cooling water channel of the engine, continues to absorb heat from the cylinders, and after repeated circulation, the engine can achieve the purpose of cooling.

However, the engine operating temperature should not be as low as possible, and the optimal temperature is around 90. How can I keep the engine water temperature at this temperature all the time?

The thermostat is mounted on the engine's water pipe and acts as a valve. When the water temperature does not rise to the preset opening temperature of the thermostat, it is equivalent to closing the valve! At this time, the coolant in the engine water jacket is not circulated to the radiator, and the entire water path is closed, so a small amount of coolant in the engine water jacket rises rapidly, which is the reason why the temperature of the vehicle rises rapidly at the beginning of driving.

Once the water temperature rises to the preset opening temperature of the thermostat, the thermostat will automatically open, which is equivalent to the opening of the water supply pipe valve, also known as the large circulation: the coolant flows into the radiator under the action of the water pump, and continues to inject into the engine's water jacket after heat dissipation, so that the engine always works at the most suitable temperature. It can be seen that the engine water temperature control is achieved by turning the thermostat on and off, the thermostat is turned off when the water temperature is low and the thermostat is turned on when the water temperature is high.

When the main valve is opened, the engine's coolant flows directly into the radiator. When the main valve is opened, the bypass valve under the thermostat will also move downwards to seal the small circulation line to ensure that the coolant will not be short-circuited and affect the heat dissipation. This is how thermostats work.

When the thermostat fails, the car's water temperature is uncontrollable, either high or low. The thermostat is always on, the engine water temperature never rises to 70-90, the engine is always in a state of large cycle, and all the heat will be dissipated. When the thermostat is always off, the engine will have a high temperature.

If the thermostat is not developed and always works in a small cycle state, the heat cannot be dissipated in time after accumulation, so the engine will have a high temperature.

The car water pump will rise within 5 minutes, and the time to rise is very fast, and the water temperature is also very high, it can be seen that the performance of the car is very good.

It can continue to rise within about 5 minutes, and the temperature temperature is still very fast, so you should pay more attention to this aspect.

The water temperature of the car will rise in about 10 minutes under normal conditions.

What will happen if the water temperature is too high when the vehicle is driving and continues to drive?

1.There is a risk that the water pipe will rupture, and the antifreeze leakage at high temperatures may occur. 2.

The continuous high temperature of the engine will cause the engine to pull the cylinder, and the most serious will also reduce the performance of the engine, and even scrap the serious consequences. Therefore, when you find that the water temperature continues to maintain a high temperature, you should stop and check in time to see what is the cause. The water temperature of the vehicle we see is too high, which is actually caused by the coolant not working normally, so we must pay attention to it, check that the problem appears, and eliminate the problem in time to continue driving.

When the vehicle is driving normally, the water temperature should be maintained at a normal scale, and the water temperature will not fluctuate greatly even if it is a long distance. When you find that the water temperature is abnormal, you should check whether the coolant is within the normal scale and whether there are any other abnormalities. When the problem cannot be ruled out, it is necessary to contact the maintenance personnel for treatment, otherwise the water temperature will be maintained at a high temperature will put the engine in an abnormal state, and the most serious will have the serious consequences of engine burning, so we must pay attention to it.

Why does the water temperature rise when the vehicle is moving?

There are many reasons for the abnormal increase in water temperature, and for ordinary drivers, you can first check whether there is any leakage of coolant in the engine compartment. When the coolant is not enough, the coolant refrigeration effect will be insufficient, so when the coolant is found to be insufficient, the coolant should be replenished in time to make it at the normal scale. In normal use, the coolant will not be insufficient, and it is generally a leakage problem, so it is necessary to check whether the pipe of the water tank has a rupture problem, and it should be repaired in time when it cannot be solved.

It was found that the water temperature was maintained in a superheated state.

If the coolant is insufficient, add coolant in time. If there is a problem with the cooling fan, it can also be replaced. If there is a high temperature caused by water pump or thermostat and other problems, we ordinary drivers can not solve it, at this time, it is necessary to repair it in time, let the 4S shop or professional maintenance personnel deal with it, do not work with illness, so that the engine is in a long-term high temperature state, causing damage to the engine.

How to prevent high water temperatures.

After knowing the reason, we should pay attention to whether the coolant is within the normal scale range when maintaining the vehicle. Especially when traveling long distances, it is necessary to pay attention to the timely addition of coolant when it is insufficient. The coolant will also be consumed on a daily basis, and it will also cause rapid coolant consumption when the car is used frequently, and it will also cause more coolant consumption when it is operated in S gear for a long time.

Finding problems and solving them can make our travel smoother. The coolant of the vehicle plays the role of cooling the engine, although it is a consumable, but the role is also not negligible, and we should also pay special attention to it when driving in daily life.

The car can't continue to drive because the water temperature is high. Under normal circumstances, the normal working temperature of the engine is about 90 degrees, which can make the engine have good power and economy, and at the same time reduce wear and prolong service life.

The engine temperature is too high or too low will cause: wear and tear, power decline and other phenomena, especially if the temperature is too high, if the engine is easily damaged if it works at high temperature for a long time, and even the engine will be scrapped in serious cases.

If you encounter high water temperature or alarm, you can simply check and judge it yourself: 1. You must immediately pull into the roadside parking lane, turn on the double flashing lights and place a warning triangle after parking to remind the rear vehicles to pay attention to avoid (especially on the highway).

2. Don't turn off the engine immediately, turn on the heater air conditioner to the maximum gear, which can help the engine dissipate heat, because the cooling water pump is driven by the engine, if the fire is turned off, the water pump will stop, and the coolant will not be able to continue to circulate, which is not conducive to engine heat dissipation, and then continue to observe the water temperature gauge, if the temperature will not drop and then extinguish the engine.

3. Open the engine cover and check whether there is any water leakage around the engine and water tank. If so, you can't continue to drive and check that the coolant in the sub tank is too low. Yes, you can add distilled or purified water, and if you find that the water temperature returns to normal, you can continue driving.

The water temperature of the car is too high to drive. If the water temperature of the car is too high, if the water temperature of the car is high, the engine head gasket will rot due to the high temperature, and then the engine may pull the cylinder. If you open it for a longer time, the cylinder head and cylinder block will be deformed, causing the engine to stall, causing the piston to pull the cylinder, the crankshaft to lock, and the engine needs to be overhauled, which may lead to the scrapping of the engine in serious cases.

What to do if the water temperature in the car is too high.

The correct thing to do is to let the engine idle in place for a few minutes, turn on the air conditioner heater, and then open the hood to dissipate heat as soon as possible.

After the temperature drops, we need to check whether the coolant of the car is sufficient, if the coolant has been lower than the min line, then the water temperature of the car is too high caused by the coolant is too low. If there is coolant on the car, then we can add it in time, if not, then you can use mineral water instead, but it should be noted that water is only for emergency use, if you use water for a long time, it will cause rust in the engine and water tank, and the water temperature will be high due to poor heat dissipation in the water tank.

Hello, the car can't continue to drive because the water temperature is high. Under normal circumstances, the normal working temperature of the engine is about 90 degrees, which can make the engine have good power and economy, and at the same time reduce wear and prolong service life.

If your car has issued an alarm on the gauge that the water temperature is too high, the vehicle will not be able to continue driving, because the vehicle engine will produce high temperatures when running, and if there is no cooling system for timely heat dissipation, it will cause the internal temperature of the engine to rise sharply, which will eventually lead to the appearance of the cylinder. It will scrap the engine, so if the temperature is too high, you need to stop the vehicle immediately.

Definitely not, the engine is dissipated by coolant circulation.

Hello, this case is not recommended.

There are many reasons for the high water temperature of the car, most of which are caused by water seepage in the water pipe and insufficient cooling water, such as broken fan belt, leakage of water tank or water pipe, thermostat failure, oil leakage, etc. If the engine power disappears or the sound of violent knocking and cylinder knocking is made during driving, it is mostly because the engine is overheating.

The specific reasons are as follows:

The cooling fan does not turn. The cooling fan may be controlled by a thermostat switch; It may also be controlled by a water temperature sensor.

Insufficient cooling medium. Antifreeze: High-end cars are required to be filled with antifreeze all year round; Water or distilled water: temporary substitute; The water tank cover is leaking.

The thermostat is damaged. If you want to remove the thermostat, you should plug the small circulation at this time, so as to ensure that all the coolant is dissipated by the water tank; When installing a new thermostat, you should pay attention to the water hole, such as Santana does not have a water hole, at this time, a 6mm drill bit should be used to drill a hole. One function is to be used as a marker; Another function is that during the heating process of the car, the temperature difference between the two sides of the thermostat is generated, so that the thermostat is accurately opened with the water temperature.

The water tank is clogged. External blockages should be removed with water or gas; Internal blockages affect coolant circulation and create pressure, which can result in two outcomes, one is a leaking water tank or the other is a particularly high water temperature at high speeds.

Pump failure. The impeller slips or gets stuck, causing the timing belt to break; The impeller is deformed.

Cylinder corrosion. The combustion chamber and the waterway are flushed, and at this time, the water will be drained from the drain pipe or white smoke will be discharged, resulting in a frequent shortage of water in the water tank; The waterway and the oil channel are flushed (the oil is white when there is water); The waterway and the waterway are rushed, resulting in poor heat dissipation of the cylinder block, especially at high speed; Blocked waterways.

Extended Information: Solutions to High Temperature in Car Radiators:

1. Pull over, put the automatic gear into P gear, and the manual gear into neutral gear, pull the parking brake handle and turn off the air conditioner.

2. If you find that the coolant is boiling and overflowing from the radiator after opening the engine cover, please turn off the engine immediately, turn the car key to the ON position, and never start the engine again, so that the electric fan of the radiator can run automatically to facilitate heat dissipation.

3. After cooling for a period of time, check the height of the coolant in the liquid storage tank, if the coolant level is low or there is no coolant at all, check whether there is leakage in the upper and lower water pipes and their interfaces, or check whether there is a break in the fan transmission belt.

Check whether the water tank is not circulating, really helping you look forward to adoption,

High water temperature means that the engine is overheated, and it will pull the cylinder and burn the oil....You have to wait for the temperature to go down before opening it, otherwise the water tank will be violent. Hello, the water temperature is high and you can't turn it on, otherwise the engine is high, you have to go to repair it in time, or stop for a while and wait for the water temperature to go down before you can open it for a while, you should always rest the water temperature to the red line and stop immediately, you can't open it again, it will damage the engine. If the water temperature is high, you need to stop immediately and you can't continue driving.

Hello, it's better not to drive, otherwise the engine will be damaged, causing trouble for engine overhaul 2019
