The temperature of the car antifreeze is abnormal, what is the cause of the high temperature of the

If the water temperature or antifreeze temperature is abnormal, it is probably caused by these reasons: the water temperature is too high: the shutter is closed or the opening is insufficient, the fan belt is loose and slippery, the fan clutch or temperature control switch is faulty, etc., so that the cooling air volume and wind speed are insufficient; The outer surface of the radiator is covered with dirt or the heat sink is dumped too much, and the scale deposit in the waterway is too much, and the heat dissipation effect is reduced; The radiator cover fails, the water pipe is aging, dented or clogged, the water pump does not pump enough water, the thermostat cannot be opened, and the coolant is less.

The water temperature is too low: the thermostat fails and cannot be turned off, and the coolant is always in a state of large circulation; The blinds cannot be closed or are not closed tightly; The timing of the fan is too early; The fan can only be rotated at high speeds; The water temperature sensor fails; The ambient temperature is too low and driving against the wind.

Upstairs, right? Didn't see a word useful. According to the subject's description, the temperature probe is good, the antifreeze is no problem, and the thermostat is normal after replacement, because there is wind in the drive, and the idle speed depends on the fan.

Since the temperature of the idle speed rises, it proves that the control line is normal. Now the reason for the analysis is: the weather is too cold, and self-cooling meets the heat dissipation

It's okay if there is less antifreeze in a car but the water temperature is not high, but it must be added in time. Confirm that there is no leakage, it is definitely the punch cylinder bed, its reflection is that the engine is weak, white smoke (light can not be seen), go to the repair shop for an inspection.

Second, the disadvantages of car antifreeze.

It can cause the car to "boil" and seriously damage the engine.

The full name of antifreeze is antifreeze coolant, and it can be seen from the name that it has two main functions: the first is antifreeze, and the second is cooling. Antifreeze prevents the coolant from freezing and bursting the vehicle's cooling system when the vehicle is parked in the cold winter, and in the summer it prevents it from "boiling".

If the "boiling", the cylinder wall around the serious water deficit, so that the engine lacks cooling, will make the strength of the piston, piston ring, connecting rod and other components reduced, even deformed, can not bear the normal load, but also will destroy the normal clearance between the parts, so that the parts can not maintain a normal oil film, the light will make the engine pull the cylinder, the swa, the heavy will also make the whole engine damage or even scrapped.

The boiling point of water is 100, while the boiling point of antifreeze is generally 110-120, which has an obvious effect on protecting the engine and preventing "boiling".

Hello: The reason why the water becomes high after replacing the antifreeze: The general situation is that the gas is not discharged when the antifreeze is changed, sometimes after the water temperature is high, the thermostat is turned on, and the antifreeze is circulated, which will discharge the gas.

Antifreeze is a kind of coolant containing special additives, mainly used in liquid-cooled engine cooling system, antifreeze has excellent properties such as antifreeze in winter, boiling in summer, waterproof scale and anti-corrosion throughout the year. At present, more than 95% of domestic and foreign water-based antifreeze uses ethylene glycol, and compared with tap water, the most significant feature of ethylene glycol is antifreeze, while water cannot be antifreeze. Secondly, ethylene glycol has a high boiling point, low volatility, moderate viscosity and small change with temperature, and good thermal stability.

Therefore, glycol-based antifreeze is an ideal coolant. Many drivers are generally accustomed to using antifreeze in winter and switching to tap water in summer, thinking that this is more economical and cost-effective, but in fact, it is not. Preventing freezing, preventing the cylinder and radiator from freezing and cracking are only the most basic functions of antifreeze, and antifreeze also has other important functions, such as anti-boiling, anti-scale, anti-corrosion, etc.

The use of antifreeze in summer can effectively prevent the water tank from "boiling", and the use of antifreeze throughout the year can prevent scale formation in the water cooling system and inhibit the corrosion of various metals.

Hope it helps!

If there is a high temperature after adding antifreeze, then most of them are because there is air in the pipeline, that is to say, the exhaust is not discharged well, if you really can't operate it, you can go to the maintenance station to get it.

The reason why the water temperature is too high with antifreeze is that the addition and replacement of antifreeze is not standardized, which causes the engine waterway and water tank to be blocked in advance, and the water temperature is high. The antifreeze must be replaced once every two years, and the original antifreeze must be used when replacing and adding, if its concentration is too high, it will cause poor heat dissipation and overheating of the engine.

The full name of antifreeze is antifreeze coolant, which means coolant with antifreeze function, which can prevent the coolant from freezing and bursting the radiator and freezing the engine cylinder block or cover when the coolant is parked in the cold winter. Antifreeze is a kind of coolant containing special additives, mainly used in liquid-cooled engine cooling system, with excellent properties such as antifreeze in winter, boiling in summer, waterproof scale and corrosion protection throughout the year.

Due to the non-standard addition and replacement of antifreeze, it will cause the engine waterway and water tank to be blocked in advance, and the water temperature will be high. Antifreeze is changed every two years, and original parts must be used when replacing and adding. If the concentration is too high, it will cause poor heat dissipation and overheating of the engine.

This hazard is less noticeable when the engine is running at a small load, and when the engine is running at high speeds, the coolant temperature will be too high. Therefore, it is not possible to add antifreeze stock solution at will.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

The antifreeze bottle has an upper and lower level limit, which must be between the two lines, not high or low.

Basically, it's okay if it's not hot, and if it's less, add it to the standard line.

Common faults with 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. The temperature of the coolant was too high because the thermostat could not be turned on, which hindered the flow of coolant inside the engine.

3. The cooling fan in the engine cooling system is not working properly, resulting in poor heat dissipation of the coolant. So the water temperature light is on, causing the coolant temperature to be too high.

4. The water pump in the engine cooling system is faulty, and the water pump does not rotate smoothly, resulting in a poor flow of coolant, so the water temperature light is on and the coolant temperature is too high.

When antifreeze is insufficient, the engine temperature will be too high, which can damage the engine.

Antifreeze is essential for the engine and is mainly responsible for the cooling of the engine. It circulates in the engine cooling system to take away the high-temperature heat generated by the engine's operation, so that the engine can run at its normal operating temperature.

Pay attention to car maintenance in winter:

Eliminate fog: The most common problem of driving at low temperatures is that the glass in the car is foggy, and the temperature knob can be placed in the warm air position to achieve the purpose of both defogging and heating.

Do you have water in your tank? That's a terrible thing, because I guess the tank is frozen, and the volume may be expanding, and the tank will freeze and burst, and the engine block will be in danger of freezing and cracking, and the whole engine will be scrapped.

Quickly extinguish the car, drag the car to a repair shop or 4S shop and other warm rooms, wait for the ice to melt, drain the clean water, add antifreeze, and then get into the car to see if the water temperature is normal.

Then look at the leakage under the engine.

It's frozen, and of course the water temperature is high if it doesn't circulate [If there is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

It is estimated that it is icy [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

The water tank may be frozen, it is not circulating, idle the car, and use the hot water in the machine to dissolve the water tank.

It is the winter when the tank freezes and causes high temperatures.

Turn off the engine immediately Your car's cooling system is frozen [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, the water is frozen, not circulating [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Check if the water tank level is normal.

There is no shortage of antifreeze in the vehicle, but there is a water temperature alarm. The water temperature light alarm is generally when the water temperature is too high. If there is no shortage of antifreeze, then several aspects are suspected.

First, there is air resistance in the cooling system. After replacing the antifreeze, the exhaust is not complete, resulting in air in the circulation system, which affects the circulation.

Second, the thermostat is faulty, and the thermostat is normally closed. Under normal circumstances, during the cold start and hot car phase of the engine, the thermostat is turned off in order to allow the engine to heat up quickly to the optimal operating temperature. Only the coolant inside the engine is involved in cooling, commonly known as small circulation.

When the water temperature reaches a certain set value, the thermostat is turned on, and the coolant in the water tank participates in the circulation, commonly known as the large circulation. If the thermostat is normally closed and only the coolant inside the engine cools down, then the engine will definitely be hot.

Thirdly, the water temperature sensing plug is faulty, or the fan is faulty. When the thermostat is turned on, the engine temperature continues to rise and reaches another set point, the water temperature sensor plug is turned on, and the tank fan starts to run to force the water tank to cool down. If the water temperature sensor plug or fan fails and cannot be cooled, it will also cause the engine to alarm for high temperature.

The water temperature gauge is bright and the water temperature is high, the reasons are that the fan does not rotate, the antifreeze is insufficient or too much, and the fuse of the water tank is burned out, which will cause the water temperature to be high.

It could be a problem with the line, or it could be. Problems with the water temperature sensor.

The car's water temperature gauge is lit up, but there is no shortage of antifreeze, it is recommended to check the water temperature sensor and the water level sensor of the kettle.

It should be that there is a problem with the car's sensors.

Hope mine can help you.

Hello, I'm helping you sort out the answers to your questions, please wait a moment Oh ask questions. Hello! What is the reason for the high temperature of the antifreeze?

Hello, I am your exclusive technician, attentive, careful, attentive to check Hu Huai for you to answer the car questions, for you to find the corresponding problem solutions and solutions, will provide you with a satisfactory answer! I hope this service can help you. If it helps you, we look forward to your likes and attention.

The reasons for the high temperature of the car antifreeze are as follows, first consider whether it is a real high temperature or a false high temperature, and the failure of the false high temperature mainly considers checking the water temperature sensor, sensor circuit, and the internal fault of the computer version.

The following aspects are checked at the true high temperature, one is whether the high and low speed of the cooling fan is operating normally, whether the temperature saving banquet can be opened normally, whether the pump wheel and transmission belt are buried normally, and whether there are faults such as damage and blockage on the surface and inside of the water tank.

Hello! Excessive temperature of car antifreeze includes:

1.Cooling system citrus leakage or insufficient cooling water;

2.The indication of the water temperature gauge is inaccurate or malfunctioning;

3.There is too much scale in the cooling system, and the heat dissipation effect is poor;

4.The shroud net or radiator core ventilation duct of the diffuse heater is blocked by debris, resulting in poor heat dissipation;

5.The belt of the water pump or fan is too loose or broken;

6.The water pump is damaged, the fan blades are reversed or deformed, and the wind ring is damaged;

7.The thermostat is damaged in the closed position of the main valve; 8.The engine is overloaded for a long time and the fuel supply time is too late.

1. There are leaking places in the cooling system, such as water pumps, water tanks, etc.

2. When filling antifreeze, there is air in the antifreeze pipeline, and after the air is discharged, the level of antifreeze will drop. 3. The engine boils water, if the engine gasket is broken, the antifreeze will be burned, and the cylinder gasket can be replaced.

4. The high water temperature of the cooling system causes the pot to boil, and the antifreeze is sprayed out, and the reason for the high water temperature needs to be checked.

That's because you don't have enough antifreeze, you need to add it! Otherwise, it will be a big problem, and it may stall when driving, which may lead to danger! I have a colleague who is also like this, he is also lucky, 2 kilometers away from the high-speed exit the car prompted that the temperature is too high, the antifreeze is almost gone, but he didn't take it seriously, and then the car stalled directly, scared him to death, fortunately it was not far from the exit at the time, and there were no other paintings on the road, he drove the car out of the ramp, and then the car had to be overhauled once, and it cost a lot of money!

Therefore, if the temperature of antifreeze is too high, you must add antifreeze, so you must pay attention to it!

No. Because the temperature is too high, it will burn the engine.

Precautions: The replacement cycle of antifreeze should be subject to the manufacturer's manual, usually every 2 years or 40,000 kilometers, and the longest is every 4 years or 60,000 kilometers.

There are a few car manufacturers antifreeze support lifelong free replacement, only need to be checked regularly, because the fluidity of this antifreeze is slightly poor, you need to pay attention to whether the cooling system circulation heat dissipation is normal. It is necessary to pay attention to the location of the antifreeze and be sure to keep it between the lowest and highest values.

If the temperature of the car antifreeze is too high, it is commonly known as the car water temperature is too high. Under normal circumstances, the water temperature of the car is constant at about 90 degrees, if the temperature is suddenly too high, it should be slowed down immediately after exceeding 100 degrees. At this time, if you continue to drive, because the engine can not cool down normally, it may cause the engine to "pull the cylinder", and the consequences will be serious.

If the water temperature of the car is too high and it is easy to damage the engine after driving for a long time, the damage is serious, which leads to the cylinder pulling of the car engine (the inner wall of the cylinder is pulled into a deep groove), so once the water temperature is found to be too high, it is best to stop for inspection and repair!
