Why do some cars always have high water temperature, why do cars always have high water temperature?

The high water temperature is definitely caused by poor cooling. 1. Check the water level of the water tank. 2。

Whether the radiator of the tank is blocked. 3. Whether the water pump is broken. 4. Whether the thermostat is broken and cannot be opened.

5。Whether the fan belt is too loose and slippery. 6。

High temperature climate, turn on air conditioning, climbing, caused by excessive load.

The water temperature of the car is high, on the one hand, because you have been in the car for a long time, and the piston ring on the nose is worn to a large extent, which will cause the water temperature to be high, and on the other hand, because your vehicle has a faulty line and there is no water in the nose, the water temperature will be high.

Hello landlord! The water temperature of the car is set by the manufacturer before leaving the factory, and some cars are set to 80-90 degrees before the electronic fan is turned on to work. This does not mean that the water temperature is high, if the water temperature is 90 degrees Celsius, the electronic fan does not work, it means that the water temperature is high.

The high water temperature has a certain relationship with the season, if the water temperature of your car is higher than 90 degrees, the electronic fan is not working, then you had better go to the 4S store to check it. See if the thermostat is normal! There is no water temperature setting change!

Is there a lack of water in the tank! Is there air in the tank! Whether the pipeline is leaking!

1. The water temperature is too high due to installation problems.

1) The distance between the water tank and the engine is too large, and the fan is outside the wind circle, which can be solved by adjusting the installation position of the water tank;

2) The air-conditioning condenser is blocked in front of the water tank, and there are two solutions: one is to change the installation position of the air-conditioning condenser if there is enough space in the engine compartment; Second, if the generator generates sufficient electricity, install an electric fan in front of the condenser.

2. The water temperature is too high due to use and maintenance problems.

1) The engine structure is compact, the corresponding waterway is small, in the southern region, soft water or distilled water must be added to avoid scale in the waterway; In the northern region, it is necessary to go to the maintenance station or regular repair shop to fill the first cooling (antifreeze) liquid to avoid cylinder head corrosion.

2) After the engine is drained with water, or the engine lacks too much water, the air in the engine may not be completely discharged after the first water filling, and if no measures are taken, it may cause air resistance and make the engine temperature too high. The solution is: after adding water, after running the engine for a few minutes, open the water filler cover and fill up the water again.

3) Gasoline can not reach the specified number (in principle, it is not allowed to be used) or the ignition time is in front, which can lead to engine detonation and make the water temperature too high.

4) Check the oil and water before leaving the car every day, and make sure the water tank is full of water.

5) The fan belt is too loose, which can lead to high water temperature. The belt tension can be adjusted appropriately.

3. The failure of some parts may lead to excessive water temperature.

1) If the idle speed of the air conditioner is too low, which can lead to high water temperature, check whether the idle speed booster of the air conditioner is working normally;

2) The plane of the cylinder head is uneven, or the cylinder gasket is flushed, which can lead to high water temperature. The inspection method is: when the engine is cold, open the water inlet cover and start the engine, if there are bubbles gushing out of the water tank, it may be the problem.

3) The failure of the parts of the engine cooling system (such as thermostat, water pump and fan clutch, etc.) can lead to high water temperature, and the corresponding parts should be checked and replaced.

There are several reasons for high water temperature in automobiles: insufficient coolant, failure of cooling fan, failure of circulating water pump, failure of thermostat, poor heat dissipation of water tank, etc. If you find that the water temperature is too high during driving, do not turn off the fire immediately, and never use cold water to flush, wait until the temperature is lower and then check what the specific problem is.

The high water temperature in the car is caused by many factors, not one-sided factors. For example, when you see the warning light on the dashboard while driving, you should find a safe place to park, and then get out of the car to check. The first step should be to check if there are any problems or a small amount of coolant in our engine compartment.

Coolant is the core substance that controls the parking space in the car. Its main function is to cool down the car. If the refrigerant is insufficient, we need to replenish it in time.

This prevents the temperature inside the car from rising. But if there is no excess, the refrigerant can be added to the mineral water first to slightly reduce the temperature in the car.

If there is no problem with the refrigerant, we need to check our tank for leaks, and then we need to check our fans. Because it may be that our fan is stuck, we need to check if the fan is still working. Although the motor of the fan is not easy to break, it can get stuck in large cases, which can also cause the temperature inside the car to rise.

If the fan is not stuck, it means that our fan relay is burned out. If it burns out, drive it in time, go to the nearest auto repair shop to repair it, and try to wait until it is repaired before hitting the road. If it burns out, driving for a long time may cause other parts in the car to burn out, causing unnecessary trouble to the car owner.

Common water temperature abnormalities are due to insufficient coolant, cooling fan failure, circulating water pump failure, thermostat failure, and so on. The water temperature of the car is a reflection of the working condition of the cooling system of the car, and the engine must run best at the appropriate high temperature, which can better make the fuel burn and reduce gas emissions at the right temperature.

If the inspection finds that the water pipe or water tank is broken, then the method just mentioned is useless, but will cause more coolant loss and the water temperature will rise faster, in which case it is recommended to stop driving immediately and call for help.

If there are no signs of water leakage, indicating that the high water temperature is not caused by a lack of coolant, then you can idle the engine in place for a few minutes, adjust the air conditioner to the warm air setting (turn off a c), turn the air volume to the maximum, and open the hood to help the engine dissipate heat. It is important to note that this method is only suitable for water-free situations.

Next, let's see if the cooling fan is working properly. When the engine water temperature is too high, even after the ignition is turned off, the fan should be running, if the fan does not move, first turn the fan blades to see if the fan motor is stuck, and it can be easily dialed when it is normal. If there is no problem with the motor, check the fan fuse, which is one of the many reasons, especially in the summer, when the electricity consumption is high, if you do not know how to check, it is recommended to call for help.

Thermostat damage is also a frequent cause of high water temperature, once damaged, it will cut off the cooling water circulation, so how to check? In fact, you can touch the two thick glue pipes above and below the water tank with your hands, whether there is an obvious temperature difference (if there is a problem with the thermostat, the upper water pipe is hotter than the lower pipe), if there is a large temperature difference, it means that the high water temperature may be the damage of the thermostat and needs to be removed and replaced, which is generally handled by professionals.

There is also a method that is not recommended, if there are tools in the car, you can temporarily remove the thermostat and let the coolant only go through the large circulation, although the temperature drops, but it will lead to increased wear and tear of engine parts, high fuel consumption and other disadvantages.

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 in the car are: 1. The thermostat is damaged, and the coolant is only circulated for a small time, and the heat is not dissipated through the water tank; 2. The cooling fan does not rotate, the temperature control switch is not turned on or the water temperature sensor fails; 3. The water pump is faulty, and the impeller slips or gets stuck, resulting in the belt breaking; 4. Insufficient cooling medium, insufficient coolant or leaking water tank; 5. The ignition timing is incorrect and the oil pressure is high, and there is a difference between the reading of the water temperature gauge pointer and the actual temperature; 6. The water tank is blocked, the external dirt is blocked, and the internal water channel is blocked to affect the circulation of coolant; 7. The cylinder is corroded, resulting in the frequent lack of water in the water tank.

1. Insufficient coolant Coolant leakage or lack of coolant will lead to an increase in engine water temperature, at this time we should check the coolant situation, if it is insufficient, first add it to the appropriate position, and then check whether the liquid level drops seriously after a few days, if there is, then we have to find the leakage of the location of the trip;

2. If the cooling fan fails, when the vehicle is running at high speed, the heat generated cannot be transferred to the antifreeze in time and affect the heat dissipation, which then leads to the increase in the temperature of the antifreeze disassembly fiber, resulting in problems such as boiling the pot;

3. Circulating water pump failure: Bearing locking and impeller damage, bearing locking is relatively rare, impeller damage is common impeller cracking or impeller loosening from the pump shaft, resulting in coolant circulation speed slowing down, easy to cause engine temperature too high failure;

4. Thermostat failureThe 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.
