What to do if the water temperature of the motor vehicle is high, what to do if the water temperatur

Normal temperature 90.

Automobile engine needs a certain working temperature when normal operation, too high or too low is not conducive to the normal operation and performance of the engine, on the other hand, the heat generated by the engine is difficult to meet the demand of conventional air cooling, so the automobile engine widely adopts the water-cooled thermal conduction design. The role of the cooling system is to keep the engine working in the most favorable temperature range to increase the power of the engine, reduce engine wear and fuel consumption. Temperatures that are too high or too low can adversely affect the operation of the engine.

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, and the normal temperature is the ** 90 of the pointer. After the vehicle starts, the temperature of the antifreeze rises rapidly, and after the pointer reaches the ** position, the temperature of the heat exchange balance antifreeze does not rise, and generally speaking, the temperature reaches the middle position when the start is the best, which is one of the reasons why the vehicle should be heated up before starting.

Generally speaking, cooling system failures mainly include leakage, insufficient coolant, cooling fan failure, and circulating water pump failure.

Hello friend, it is recommended to check the thermostat, fan motor, belt, ignition timing, water tank for lack of water or too dirty?

Hello, I can't open it, and I need to turn off the engine and stop it for maintenance.

Cars can also have a high fever just like people, what should I do if the car is hot?

If you are driving, you should pull over and stop immediately, and if the water temperature gauge exceeds the red line, you should not turn off the engine immediately and keep the engine idling. 1. Check whether there is still cooling water. 2. Whether the fan is started.

3. Test the water inlet and outlet pipes of the engine by hand to see if the temperature is about the same, if it is about the same, it proves that it is a problem with the circuit rather than the engine. But if the difference is large, it should be a problem with the engine water circulation. Let's get in on the repairs in time.

Check the coolant. Yes or no sufficient! It is best to go to the 4S store for a detailed inspection.

Cars can also have a high fever just like people, what should I do if the car is hot?

Solutions to high water temperature:

1. Check whether the water tank is leaking, open the water tank to see if the water surface height is below min, if the water level is very low, it is likely to be water leakage. Add water, open the exhaust screw near the engine to exhaust, and check for water leakage. The presence of gas in the tank can also cause the water temperature to be high.

Water leakage is generally a cool car leakage, so check after the hot car is cooled, pay attention to see if there is a leak in the warm air and water pipe joint leading to the driver's cab, and look at the ground under the car when you get up in the morning when the leakage is large. If there is no leakage, but the water gradually falls below the lowest point after a week or half a month of filling up the water, then there is another possibility that the cylinder gasket is leaking and the water seeps into the engine and consumes. Open the oil filler to see if there is white foam and bubbles, see if there is oil in the water tank cap, and see if there are white water droplets on the oil dipstick.

If so, water seeps in. The cylinder gasket needs to be replaced.

2. Change the water temperature sensor. If you don't boil the pot, it just shows that the water temperature is high, and it may also be caused by the inaccurate water temperature sensor. Change the water temperature sensor.

3. Change the thermostat. After the water temperature reaches 90 degrees, open the cabin cover and touch the water pipe near the engine to heat (be careful of hot hands), the water tank is not hot, that is, the water is not circulating. It's hot on both sides. Otherwise, the thermostat should be replaced.

4. Water change pump. The water pump is the most expensive, so you have to change it last. I have seen with my own eyes that there are a lot of rubber strips twisted in the pump of my car, and the pump is not working well, and the water cannot be circulated, causing the water temperature to rise rapidly.

This necessitates the replacement of the pump.

The cooling system of the car is mainly to dissipate heat from the engine, simply put, it is to let the cooling water enter the water jacket of the engine, and then enter the radiator, and the temperature of the water is lowered by the natural wind and fan, and finally the water that has dropped in temperature is returned to the water pump, so that it works back and forth to cool down the engine. So, what to do if the water temperature in your car is too high? If the water temperature is too high, we have to stop and check it immediately, otherwise if we continue driving, the engine will be damaged.

So how do you do that? Don't worry, follow this step.

First of all, if you find that the water temperature of the car is too high, you must first stop the car, 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.

If the water temperature is too high, do not turn off the car immediately. Many novices encounter this situation and will immediately turn off the car, which is not right. Because the cooling system of the car will only run normally when the engine is working, if the engine is turned off, the cooling system will not have the power to work anymore, and each part of the engine will still be at a very high temperature, not to mention that it will damage the engine.

The correct thing to do is not to turn off the engine immediately, let the engine continue to work for a while, turn on the air conditioner to the maximum, and then open the front cover to speed up the heat dissipation, and then turn off the engine when the temperature has almost dropped.

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. Check the water tank, water pipes and other accessories for leakage. 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.

As long as you follow this step, you can find the root cause of a simple problem of high water temperature.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! The relevant scheme is as follows: you have to check what fault is caused by the first, the water temperature of the car is too high first, if it is the fault caused by the thermostat not opening, you can directly replace the thermostat second, the fault caused by the car's cooling fan does not work must be checked first, to see whether it is the fault caused by the damage of the electronic fan, or the fault caused by the damage of the controller, and the replacement of the electronic fan or controller can be the third, you have to check whether it is the fault caused by the broken engine belt, if the belt is broken, Do you have to check the water pump and generator first, etc., whether there is any card issuance?

Then replace the belt can be the fourth, due to the fault caused by the blockage of the car water tank, directly dismantle the water tank to dredge the water tank that is, the fifth, due to the car cylinder, mattress, punch caused by the failure, this has to disassemble the engine down, and replace the cylinder mattress can solve the fault.

The water temperature is too high because the cooling system is leaking and the coolant is insufficient; The cooling fan is stuck or damaged, and the heat dissipation function cannot be achieved; Long-term high-speed driving is easy to cause the water temperature to be too high; There are also other common ones: broken fan belts, leaking water tanks or pipes, thermostat failures, oil leaks, pump failures, etc.

Solution: If you find that the water temperature is too high due to coolant loss, you can add a small amount of distilled water for emergency (note that do not open the water tank cover at high temperature, there is a risk of scalding); For the problem of high water temperature caused by vehicles that have been driving for a long time, you can pull over, turn on the hazard warning lights, and then let the vehicle cool down naturally; If the cooling fan is damaged, you also need to find the nearest repair shop for repair as soon as possible; If the thermostat is damaged, the small circulation should be plugged when disassembled, so as to ensure that all the coolant is dissipated by the water tank;

If we find that the water temperature is too high during the normal driving of the vehicle, then we can open the engine cover and touch the water inlet and outlet pipes of the tank with our hands to see if there is a temperature difference; If there is a temperature difference, it means that the thermostat is faulty and cannot work properly, resulting in high water temperature. A faulty fan is also one of the causes of high water temperatures. The fan does not run, resulting in insufficient heat dissipation in the water tank, which causes the water temperature to be too high.

There are many reasons why the fan will not rotate, it may be that the fan motor is faulty, the thermostat is not working, or the fan fuse is blown out. How can I prevent the water temperature from getting too high when I use the car on a daily basis? Too high a water temperature can easily cause various malfunctions of the vehicle and even damage the engine.

Therefore, we must regularly check the condition of the coolant in the daily use of the car and replace it regularly. Various rust inhibitors and anti-foaming agents are added to the coolant, which can effectively reduce the rust of the cooling system and the generation of coolant foam.

The treatment method of high water temperature in the car is: you can add a small amount of distilled water for emergency (note that do not open the water tank cover when the temperature is high, there is a risk of scalding), for the problem of high water temperature caused by vehicles that have been driving for a long time, you can pull over, turn on the hazard warning lights, and then let the vehicle cool down naturally. If the car cooling fan is damaged, it should be replaced in time.

The normal water temperature of the engine is between 85 and 95 degrees Celsius, when the water temperature is too high, the oil viscosity will become thinner, the lubrication performance will decrease, and the piston, valve and other parts are easy to deform when running at high speed, resulting in engine weakness, and in serious cases, the cylinder and crankshaft will be pulled and the crankshaft will hold the pad.

The solution to the high water temperature of the car is as follows: 1. Stop the car and put warning signs on the front and back of the car to deal with the problem of high water temperature. 2. Do not turn off the heat immediately.

3. Check whether the coolant of the water tank is below the standard line. 4. Check whether the water tank, water pipe and other accessories are leaking. ”

After parking the car, first check whether the coolant of the auxiliary tank is too low, open the engine cover, and see if the coolant level of the auxiliary tank is normal, if the coolant level is lower than the "min" line, it means that the coolant has been too little. Wait a while before adding coolant.

If the temperature of the engine water tank of the car is too high, you should pull over and stop in a safe area, put up a warning sign next to it, open the engine cover, and turn off the engine. Then wait a while until the water temperature of the engine has dropped sufficiently, and then check the amount of cooling water in the engine.

The common faults of high water temperature are: 1. The antifreeze in the engine cooling system is missing, which may be the leakage point of the engine, such as water pump leakage, pipeline damage, water tank damage, etc. 2. The thermostat in the engine cooling system is faulty, resulting in too high water temperature.

Because the thermostat could not be opened, the flow of coolant inside the engine was blocked.

What should I do if the water temperature in my car is too high? Hello friend, if the water temperature is too high when driving at this time, you should stop the car at this time, park on the side of the road, and then check the water tank after the water temperature drops down, and add antifreeze.

My fan is on, the fan stops, your fan is turned on too late, if the engine is continuously uphill, the pot will definitely be turned on, quickly change the thermostat.

To stop and check whether the cooling water of the water tank is normal, whether there is any leakage at the water tank, water pipe and each joint, you can make up the cooling water according to the regulations, and the temperature is still high for a period of time

Check the engine coolant, with.

It's going to be added when it's done. If not.

For this reason, slow speed is recommended.

Drive to the car repair point for maintenance, and contact the tow truck maintenance if you can't drive. Repair.

No matter what mood you are in, no matter how you are today, no matter where you are, remember...Smile. There is no dress rehearsal in life, only live broadcasting, so try to do your best in everything!

Many people say that cheap cat food is not good, 20 yuan a pound of cat food is a watershed, most people can afford it, but not all of this ** cat food is good.

1. When the pot is boiled at low speed, stop and turn off the fire as soon as possible

When you find that the water temperature of the car enters the warning line, if the vehicle is driving at low speed, it is generally a problem with the cooling system, it is recommended to immediately find a safe place to stop without obstructing others, and then turn off the engine. Pay special attention not to panic in the emergency stop to prevent rear-end collision by vehicles behind.

Second, when the pot is boiled at high speed, it is necessary to stop and idle:

If you are driving at high speed and find that the water temperature of the car has entered the warning line, do not turn off the engine immediately after pulling over, but should keep the engine idling for a period of time. Because the speed of the heat generated by the machine when the engine is running at high speed exceeds the speed of the heat discharged by the electronic fan and the water tank, it produces high temperature retention, if it runs at low speed for a while, the temperature will inevitably drop, after cooling for 15 minutes, observe the dial, if ** to the normal area, then you can keep the low speed and continue driving.

Note: A warning triangle must be placed after parking.

If the vehicle is "boiling" halfway, after we park on the side of the road, we must remember to place a warning triangle 50-100 meters behind the car to remind the rear to pay attention to avoidance. If you are on a motorway, we need to increase the distance between warning signs to at least 150 meters.

3. Check the cause of the car water temperature alarm

Step 1: Check whether the coolant level in the coolant reservoir is too low.

If the water temperature is too high due to insufficient coolant, we can add coolant if there is spare coolant in the cabin or if there is another way to obtain coolant.

For example, if we see the warning light on the dashboard in the process of driving, we should find a safe place to park, and then get out of the car to check, the first step should be to check our engine compartment, whether there is a problem with the coolant or the amount is less, the coolant is a core substance in the car to control the parking space, its main role is to cool the car, If the refrigerant is insufficient, we should add it in time, so that the temperature in the car can be avoided, but if there is really no backup, the refrigerant can be added with some mineral water to reduce the temperature of the car slightly.

If there is no problem with the refrigerant, we need to check whether our water tank is leaking, and then check our fan, because it is possible that our fan is stuck, so we need to check if the fan is still rotating? Because the motor of the fan is not easy to break, but there is a great situation that will be stuck, which will also cause the temperature in the car to rise, if the fan does not appear stuck, that is, our fan continues to burn out, if it burns out, we should drive it in time, the nearest car repair shop for repair, try to wait for the repair before driving on the road, if in the case of burning, continue to drive for a long time, it is possible to cause other parts in the car to burn out, thus bringing unnecessary economic losses to the owner, If it's serious, it may cause unnecessary trouble.

If there is no problem with the above, then we should check the glue pipe above and below the water tank, we had better touch it with our hands, feel the temperature difference is not obvious, if the temperature difference between the two glue pipes is particularly large, this time is because the eyelash device is broken, we need to replace the eyelash device in the car, here I would like to tell you, we should not think that as long as the car can still be driven, there is no problem, if we do not check and repair when the car has a small problemAt that time, because of the big problem caused by a small problem, it is not a simple repair can be done, especially when your life safety will be threatened, here to say, when driving must always pay attention to our car, if there is a problem, must be repaired and then continue on the road.
