Can the thermostat of the car water cooling system be removed casually, and why?

It is better not to dismantle the thermostat at will.

The engine is not installed with a thermostat, which has little impact in the summer, but the important thing is in winter, the temperature is relatively low in winter, and the driver will use the heating system when driving, and the heating air of the car depends on the water temperature of the engine to heat.

If there is no thermostat, it means that the water temperature comes up slowly, and then the warmth is also slow, so when driving in winter, the engine must be installed with a thermostat, otherwise the car will not be warm, although a little car with electronic heating function, electronic heating can bring warm air, but there are many people who do not have the function of electronic heating.

The difficulty of removing the thermostat varies from car to car, but most of them are not too troublesome, and I think the reason is that it is easy to replace, after all, this is also a wearing part. I'm not sure if you ask if you can remove the thermostat, if this is the case, it can be removed, but the temperature of the engine will rise more slowly, in fact, the engine is not the colder the better, too low temperature will increase fuel consumption, the best working temperature is 8, 90 degrees, the purpose of the thermostat is to control the circulation of coolant at low temperatures, in order to accelerate the engine heating, and at high temperatures, open the valve, use coolant circulation to cool the engine. So as long as your engine is regularly replaced with regular antifreeze and the water pump is working properly, there is no need to remove the thermostat at all.

Check whether the temperature sensor switch on the water tank is damaged, whether the fan motor of the water tank is damaged, whether the circuit is broken, whether there is too much fouling in the water tank, whether the water pipe is blocked, and whether the water pump is damaged.

Stuck, emergency use, otherwise continue to drive will open the water tank, but you have to block the small circulation channel.

Some vehicles do not dissipate heat well (old engines, high water temperatures, or poor ventilation. The cost of continuing to repair is too large), rough maintenance and use, it is not recommended.

The function of the thermostat is to maintain the operating temperature of the engine. The optimal operating temperature of the engine is 80-90 degrees. In this temperature range, the fuel atomizes well, burns more fully, and engine drag and mechanical wear are minimal.

At this time, the engine is at its most efficient. The thermostat is a key element that keeps the engine water temperature between 80-90 degrees.

<> designed an engine thermostat to control the engine water temperature. At start, the thermostat cycle is small and the engine temperature rises rapidly. When the temperature is above 50, the thermistor of the thermostat will gradually turn on.

When the temperature is above 85, the thermostat will be fully turned on and there will be a large cycle between the tank and the engine. In this way, the thermostat is adjusted according to the engine water temperature and controlled within the standard range to achieve the best working efficiency of the engine. If it's too high, the electronic fan starts to cool the rubber slippery.

There is no specific mileage to replace the thermostat on the car. If it's broken, it needs to be replaced. Some can replace two in a year.

As long as the water temperature is normal and the heater is normal, it does not need to be replaced. If the water temperature is high or the water temperature does not rise, the abnormal cooling of the Zhongjing air conditioner may be related to the thermostat and should be replaced according to the specific situation.

There is no fixed replacement time, and the safe life of the thermostat is 50000km. Therefore, it needs to be replaced regularly according to its safe life. Thermostat Precautions:

1.Coolant temperature over 110 degrees: stop the engine, turn off the engine, open the engine compartment cover, touch the water pipe (liquid) in the coolant radiator with your hands.

The tube should be hot. Touch the radiator water beam wax (liquid) tube again and it is very hot. If there is a large temperature difference between the upper and lower pipes, it is determined that the thermostat is faulty.

2.Normal operating temperature is not reached for a long time: Stopping causes the engine temperature to drop to the same level as the air temperature, and then starts the engine to drive.

The working principle of a normal thermostat is that after the engine starts, the cooling water temperature is low, the thermostat switch is turned off, and the cooling water only "circulates" in the engine body. As the temperature of the cooling water increases, the thermostat gradually opens, and the cooling water is in the "big circulation and small circulation" at the same time. When the cooling water reaches a certain temperature, the thermostat is fully opened, and the cooling water is "circulated".

I judge that Wang will choose the original orange boy, and will definitely choose the best one, and will choose the big brand, so that it will not affect the driving performance of the car and will not affect the safety of the car.

When choosing a car thermostat, I will choose the one that suits my car, but also choose the original, if it is a sail cover some small manufacturers of thermostats on the car's state beam damage is very large, will also affect the use of the car engine.

I will definitely choose the kind of ***, and then I may choose the same brand as the car tour, and the rubber grinding stool may have a relatively high fit Liang Brigade.

If you don't use it for a long time, you can leave it out, which can save a little cost.

1. Turn off the engine and open the front hood. The purpose of disconnecting the negative wire of the battery is to prevent the sudden operation of the electronic fan during work, which may cause injury to people.

2. Remove the plastic cover plate on the outside of the timing belt.

3. The location of the generator will affect the thermostat, and the generator assembly needs to be removed. When the drain pipe is removed, the antifreeze gushes out, so be careful of scalding. At this point, the thermostat itself can be seen. Remove the faulty thermostat and install a new one.

If the car thermostat needs to be installed, you need to go to the car's repair shop to install it to avoid installing the thermostat parts of the car that damage the car. It is necessary to put coolant.

When the temperature of the antifreeze is relatively low, the thermostat is in a closed state, and only the antifreeze in the engine is heating up. When the antifreeze in the engine rises to a certain temperature, the thermostat will automatically open to form a communication with the water tank.

The opening temperature of the thermostat on the engine of different models is also different, such as the Ford's engine had a long-term high temperature failure before, which is caused by the thermostat being turned on too late. Basically, it opens at more than 90 degrees Celsius. Don't look at the opening temperature is only a difference of more than 10 degrees, but for the engine, it is still quite different.

Need 1It is best to use the lift to lift the car first, remove the water drain screw under the water tank, and drain the antifreeze, so as to avoid waste.

2.The thermostat automatically adjusts the amount of water entering the radiator according to the temperature of the cooling water, and changes 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. The thermostat must be kept in good technical condition, otherwise it will seriously affect the normal operation of the engine.

If the main valve of the thermostat is opened too late, it will be 3It can cause the engine to overheat; If the main valve is opened too early, the engine warm-up time will be prolonged, and the engine temperature will be too low.

The function of the thermostat is to keep the engine from subcooling. For example, after the engine is working normally, the temperature of the engine may be too low if there is no thermostat in the winter. At this time, the engine needs to temporarily stop the water circulation to ensure that the engine temperature is not too low.

Connect the water tank to the water tank and the thermostat cover, remove the thermostat and put the thermostat inside, and restore it as it is! The coolant can be left undrained, but the water tank lid must be opened.

It is generally installed on the edge of the engine cylinder head, and it must be cooled when disassembled, otherwise it will burn !!

It is better not to dismantle the thermostat at will.

The engine does not install a thermostat, it has little impact in summer, the important thing is to leak in winter, the temperature is relatively low in winter, the driver will use the heating system when driving, and the heating air of the steam disperse car is to rely on the water temperature of the engine to heat.

If there is no thermostat, it means that the water temperature comes up slowly, and then the warmth is slow, so when driving in winter, the engine must be installed with a thermostat, otherwise the car will not be warm, although a little car with electronic heating function, electronic heating can bring warm air, but there are many people who do not return to the function of electronic heating.

Car thermostats are not as famous as engines, brakes, tires, etc. It can ensure that the temperature of the engine is appropriate, and the cooling water temperature and heat dissipation can be adjusted.

In order for the engine to reach the operating temperature quickly, an idle poppet valve and a thermostat are designed. When the thermostat is cold started, it uses a small amount of circulating water. When the temperature is about 85, the thermostat is fully turned on and the cycle is extended.

With the change of temperature, the opening of the thermostat thermistor can be adjusted at any time to control the water flow and control the engine water temperature within the normal working range. When the water temperature is normal, the idle speed will immediately drop to the normal idle speed of about 750 rpm. If the thermostat is removed or damaged, the engine water temperature will not be properly controlled.

Only if the thermostat fails, can the thermostat be removed temporarily. The thermostat cannot be removed for a long time. When the thermostat is removed, the water temperature does not reach normal water temperature quickly.

Long-term low temperature will reduce the combustion efficiency of jujube and increase fuel consumption. The gap between the parts becomes larger, causing the fuel to start burning.

Especially in winter, the car may have been working in low temperatures. If there is no thermostat, it means that the water temperature rises slowly, and so does the subsequent heat rise. As the temperature rises slowly, the engine computer adjusts the amount of oil according to the temperature, which will lead to an increase in fuel consumption.

Low engine operating temperatures can accelerate early wear of cylinder liners and pistons. Damage to the transmission synchronizer due to low temperatures, high idling, difficulty shifting, or noise when shifting. Under normal circumstances, thermostats are not used in the summer, and temperatures are high throughout the year.

If it is an old car, due to the large size of the waterway bench, the gray head and impurities outside the water tank are covered, and the engine water temperature is high. We deliberately removed the thermostat in the summer and installed it in the winter. This is not recommended.

If the temperature saving machine of the car is dismantled, it will affect the working temperature of the engine, and it will also affect the thermal efficiency of the engine, which may make the car appear insufficient power, and may also increase fuel consumption; I think that cooling water is of no value, if you want, you can use a basin to catch it, and then filter and precipitate, but in fact, it is not necessary, a dozen yuan can be congratulated to buy another bucket.

That disturbance will cause the temperature and lead of the car to wither too high, which may lead to the phenomenon of spontaneous combustion of the car in failure. These cooling waters can be treated centrally, so that it can be carried out**.

If you dismantle it, the temperature of the car may rise sharply and it will be easy to scrap, so you should go to a specialized repair shop**.

The thermostat automatically adjusts the amount of water entering the radiator according to the temperature of the cooling water, so as to ensure that the engine works within the appropriate temperature range, which can save energy consumption, etc. Because the engine consumes a lot of oil at low temperatures, it is very harmful to the car, and it is easy to cause carbon deposition and bring a series of problems. Then, the car patiently introduced the dismantled car thermostat to the friends.

Introduction to Automobile Thermostats: Introduction.

A thermostat is an automatic temperature regulating device that typically contains a temperature sensing element. It turns on and off the flow of antifreeze by expanding or contracting, that is, it automatically adjusts the amount of water entering the radiator according to the temperature of the antifreeze, changes the circulation range of antifreeze, and adjusts the heat dissipation capacity of the cooling system.

Introduction to Automobile Thermostats: Principle.

A thermostat is an automatic temperature control lap device, which usually contains a temperature sensing element. It turns on and off the flow of antifreeze by expanding or contracting, that is, it automatically adjusts the amount of water entering the radiator according to the temperature of the antifreeze, changes the circulation range of antifreeze, and adjusts the heat dissipation capacity of the cooling system.

The key to the thermostat currently in use is the wax thermostat, which regulates the circulation of antifreeze through the principle of thermal expansion and contraction of the internal paraffin. When the cooling temperature is lower than the specified value, the refined paraffin in the thermostat temperature body is solid, the thermostat valve closes the channel between the engine and the radiator under the action of the spring, and the antifreeze returns to the engine through the water pump, so that the engine is circulated for a small time. When the temperature of the antifreeze reaches the specified value, the paraffin wax begins to melt, gradually becomes a liquid, and the volume increases accordingly, compressing the rubber tube to shrink, and at the same time the upward thrust acts on the pusher, and the pusher produces a downward thrust on the valve to open the valve.

At this point, the antifreeze flows back to the engine through the radiator and temperature control valve, and then through the water pump, where it circulates in a large way. Most thermostats are installed in the outlet pipe of the cylinder head, which has the advantage of simple construction and easy evacuation of air bubbles in the cooling system. The disadvantage is that the thermostat often turns on and off when working, causing oscillations.

Well, can the car dismantling thermostat briefly introduced by today's car friend be used? That's all. I don't know if my friends can use the removed car thermostat after listening to the brief introduction of the car.
