What should I do if the warm air is not hot after the car is boiled and antifreeze is added

Hello! The warm air is not hot because there is air in the water pipes! You have to find the cause of the heat first!

It would be nice to solve the warm wind! I hope it can help you! Car questions, ask the car guru!

If you don't understand the landing car master look for me!

When this happens, the owner immediately finds a safe place to park the vehicle, but the owner must never turn off the car immediately. Keep the engine idling so that it continues to dissipate heat, while opening the engine's hood to increase the rate of dissipation.

Note: Do not do the following while the water temperature is boiling:

1. Do not try to continue driving, so as not to cause greater damage to the car.

2. Don't try to open the car's radiator lid immediately, otherwise you are likely to be scalded by the hot liquid spraying out.

3. Do not pour cold water on the engine block and cylinder head, which is very likely to cause the cylinder block to be blown up due to quenching After a period of time, we are checking whether there is water leakage under the car. Be sure to wait until the water thermometer hand has dropped to the appropriate temperature position before turning off the engine.

Wrap the water tank cover with a wet towel, and then slowly open the first channel switch (about 1 4 turns), wait for the water vapor pressure to be effectively released, and then completely open the water tank cover after the release is completed, check the water volume and quality in the water tank, and whether there is any abnormality in the fan belt. If the amount of water is insufficient, you should slowly add water to the vicinity of the highest marking. If the water tank is leaking or the fan belt is loose or broken, call the towing company's ** and wait for the tow truck to rescue.

The reason for the "boiling" of the car water tank is generally due to the insufficient water level and the water tank. Rust, water leakage, etc., that is, these causes cause the tank temperature to reach the boiling point. At this time, the engine will not dissipate heat.

On the other hand, it will lead to too high temperature, and the viscosity of the oil will decrease, which will aggravate the wear of each part.

There is no need to worry about the car "boiling".

Teach you how to cope.

Under the "baking" test of hot weather, not only people are too hot to stand, but the car is also so hot that it is "boiling"! Found that the car tank is "boiling", we can do this:

1.If you encounter an alarm of high water temperature while driving, you should slow down in time and stop in a cool place on the side of the road.

2.Keep the engine idle without stalling. At this time, the parts are in an expanded state, and the flameout is easy to cause the soft metal to fall off or even stick to the cylinder.

3.When "boiling", remember not to add water immediately. When the temperature drops, unscrew the water tank with a damp cloth and add antifreeze after the water vapor is slowly discharged.

If there is no antifreeze, you can add cold water for emergency, but replace the antifreeze afterwards to avoid scale in the water tank and affect the heat dissipation performance.

Prevent the car from "boiling".

It's important to check ahead of time.

In the hot summer, it is recommended that the owner remember to check the water tank before going out, and add it in time if the antifreeze is insufficient. Usually, it is also necessary to develop the habit of cleaning the radiator sheet regularly, cleaning the water tank in time, and paying attention to the temperature of the water tank during long-distance driving, so as to avoid the "boiling" of the water tank and delaying the trip.

Boiling the pot is to indicate that the engine is overheating, antifreeze is antifreeze, and cold is generally coolant.

What is the reason why the warm air is not hot after adding antifreeze? What is the reason why the warm air is not hot after adding antifreeze? The fact that the vehicle heater system does not heat can be divided into two reasons:

One is caused by the engine cooling system, and the other is caused by the poor work of the control mechanism of the warm air. After adding antifreeze, the warm air is not hot, it may be that the water tank is blocked, and there is also a situation where the cylinder gasket is broken down and the antifreeze deteriorates, so it is recommended to go to the 4S shop for maintenance and inspection. Automobile air conditioning refers to the air conditioning device installed on the car, which can refrigerate, heat, ventilate and purify the air in the cabin, provide a comfortable riding environment for passengers, reduce the fatigue intensity of the driver, and improve driving safety.

The full name of antifreeze is antifreeze coolant, which means coolant with antifreeze function, which can prevent the coolant from icing, swelling, radiator and freezing engine block or cover when the coolant is stopped in the cold winter. @2019

OK. If not, there will be impurities in the water, which will react with the substances in the antifreeze liquid of the original slag, the light one will reduce the antifreeze effect, and the heavy one will deteriorate the liquid and corrode and damage the water tank.

The full name of the frozen grip hole liquid should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze prevents coolant from freezing and cracking radiators and freezing engine blocks or covers when the coolant freezes when parking in the cold winter.

Changing antifreeze doesn't have much to do with whether the warm air is hot or not. Antifreeze is anti-freezing, anti-boiling, anti-rust, anti-foaming, and the warm air is not hot, which can be considered to be due to the stagnation or damage of the thermostat, whether the water pipe of the warm air tank is blocked, and the mixed air switch or mixed air motor is damaged.

The structure of the heater water tank is actually a reduced version of the engine water tank radiator, which is a number of small heat dissipation pipes, which are easy to clog as well as the water tank radiator. After the inside of the infiltration warm air tank is blocked, the coolant speed of the flow plexus imitation slag slows down, the flow rate becomes smaller, the heat is insufficient, and the air conditioner heater is naturally not hot.

Automobile warm air circulation is a parallel pipeline in the small circulation pipeline of engine coolant, which is connected to the warm air water tank, and the blower blows the warm air water tank to produce warm air, which is how the air conditioning warm air comes. The lack of coolant in the cooling system is the most common and easiest fault phenomenon that causes the warm air to not be hot.

1. The water temperature of the engine has been very low, which will lead to no way to reach the temperature required for heating work, and the wind will not be hot.

2. The heating water tank of the truck is blocked, which will also cause the air conditioning air to be unable to heat up, at this time, there is no way to repair it, so you can only go to the maintenance factory or 4S shop to find professional staff to help repair, and the maintenance personnel will remove the water pipe in the heating water tank and rinse it with a high-pressure water gun.

3. The cooling system of the truck is faulty, and the temperature of the coolant cannot reach the normal range, which will lead to the heating of the air conditioner is not warm, and there is air resistance inside the cooling system, which will also produce this situation.

4. The heat exchanger of the truck is damaged, which will cause the warm air of the car to be not warm, and it is necessary to go to the maintenance plant to find professional personnel to see what the reason is, if one of the small parts is broken, it is necessary to replace the parts, and the whole heat exchanger is broken, and the entire exchanger should be replaced.

Changing antifreeze has little to do with warm air. Antifreeze has the functions of antifreeze, anti-boiling, anti-rust and anti-foam. Generally, when the warm air is not hot, you can consider whether the thermostat is stuck or damaged, whether the water pipe of the warm air box is blocked, whether the air mixing switch or gas mixing motor is damaged, and so on.

You can take the car to the repair shop for a closer inspection and then troubleshooting. The reasons why the warm air is not hot after changing the antifreeze are:1

The structure of the heater tank is actually a smaller version of the engine radiator. There are a lot of tiny heat pipes in there, which are just as easy to clog as a radiator in a water tank. After the inside of the heating tank is blocked, the coolant flowing through it becomes slower, the flow rate becomes smaller, the heat is insufficient, and the warm air of the air conditioner is naturally not hot; 2.

The cooling system is short of coolant. Coolant is commonly known as antifreeze, and the warm air of the car air conditioner comes from this. The principle is different from that of household air conditioners.

Automobile heating air circulation is a pipeline in parallel in the small circulation pipeline of engine coolant, the pipeline is connected to a warm air tank, and the blower blows the warm air tank to produce warm air, which is how the air conditioning warm air comes from; 3.Lack of coolant in the cooling system is the most common and easiest fault to solve, resulting in unheated warm air. Causes and solutions for car heaters not to be hot.

Thermostat failure: The common fault of the thermostat is that it cannot be opened. However, due to the failure of the thermostat, the reason why the warm air is not hot is that the thermostat cannot be closed, commonly known as the normally open thermostat. 4.

When the thermostat is normally on, the coolant circulates from the engine idling. If the water temperature is low for a long time in the northern winter, the warm air of the air conditioner will naturally not be hot. It is evident from the water temperature gauge that the hand is significantly lower than the normal scale.

In addition, the low water temperature of the engine for a long time leads to high fuel consumption and increased wear (the engine does not work at the optimal temperature). If the water temperature is low for a long time, it needs to be repaired and inspected immediately.

It may be caused by the radiator stopping and the water temperature being too high.

In fact, the high temperature of the engine makes the temperature of the antifreeze rise and reach a boiling state, and the overflow will emit white smoke when it hits the high-temperature metal.

Boiling antifreeze may be due to the radiator stopping and causing the water temperature to be too high; The antifreeze does not circulate, the thermostat is not turned on, and the water pump fails to work normally, causing the water circulation pipeline to be blocked, resulting in boiling; It may also be that the antifreeze is insufficient or the quality of the antifreeze residue is not good, the boiling point is low, and it is easy to boil.

If the antifreeze is boiled, it is recommended to pull over, let the engine idle for a period of time, let the temperature slowly drop down, check whether the heat dissipation system is running normally, check the amount of antifreeze, if it is caused by insufficient antifreeze, after the engine temperature is reduced, replenish it in time, if there is no antifreeze, you can add a small amount of water as a last resort, and go to the nearest repair shop for repair and replacement.
