What s going on with the car heater heating up slowly?

1. Thermostat.

Normally open or the thermostat is turned on too early, so that the cooling system is prematurely circulating, and the outside air temperature is very low, especially when the car is running, the cold air quickly brings the antifreeze.

Cooling, the engine water temperature will not rise, and the heater will not be hot.

2. The impeller of the water pump is damaged or lost, so that the flow through the small water tank of the warm air is not enough, and the heat cannot come up.

3. There is air resistance in the engine cooling system, which leads to poor circulation of the cooling system, resulting in high water temperature and unheated heat. If there is always gas in the cooling system, it is likely that the cylinder head gasket is damaged and the gas is flowing into the cooling system; If the inlet pipe of the warm air small water tank is very hot and the water outlet pipe is cold, this situation should be that the warm air small water tank is blocked, and the warm air small water tank should be replaced.

Because the car's heating system has not been used for a long time, it is inevitable that there will be many minor failures. As a car owner, you can do the following steps first:1

Check the hot and cold windshield to see if the air conditioner is adjusted to the hot windshield; 2.Check the electronic fan temperature control switch; 3.Check the water temperature thermostat.

Generally speaking, the lack of heat in the vehicle heating system can be divided into two reasons: one is caused by the engine cooling system, and the other is caused by the poor operation of the heating control mechanism. These problems are more difficult than ordinary car owners, and some are more complicated to repair, so professionals should be hired.

There is air resistance in the engine cooling system, the warm air tank and filter are clogged or there is a problem with the air volume control mechanism, the water pump is damaged, the thermostat is normally open or the thermostat is turned on too early.

It is normal for the heater to heat up slowly in winter, The working principle of the heater: when the coolant of the engine rises to a certain temperature, the coolant flows through the heat exchanger in the heating system to exchange the air sent by the blower with the engine coolant, and the air is heated and sent into the car by the blower. The disadvantage is that the coolant temperature must rise to a high cycle before the heat can be supplied, which requires a slightly longer process.

In fact, because the engine has just started in winter, the temperature of the water tank is still very low, and it is not only impossible to quickly increase the temperature in the car when the air conditioner is turned on, but it increases the burden on the engine and delays the normal increase in engine temperature. The engine should be started to warm up first, wait for the engine temperature pointer to reach the middle position, and then turn on the heater and air conditioner, and at the same time set the air circulation to external circulation, so that the cold air in the car can be excluded from the car, wait for 2 or 3 minutes, and then set the air circulation to internal circulation.

First of all, if you want the car air outlet to blow out the warm air quickly, the correct way is to start the engine to warm up first, then turn on the warm air conditioner, and at the same time set the air circulation to external circulation, so that the cold air in the car can be discharged out of the car, wait for 2 to 3 minutes, and then set the air circulation to internal circulation. Since the temperature inside the car tends to be cooler than the outside at first, it is okay to wait outside the car in the absence of bad weather. More professional knowledge of new energy vehicles is in the "excellent engineer", from easy to difficult, from shallow to deep, all-round learning, Weixin hall master.

Here we should also popularize the precautions for using car heaters, usually temporary parking on the side of the road or long-term traffic jams, as well as when the car is stationary for a long time in the car, many drivers like to turn on the heater. However, this is not true, and it can cause the risk of carbon monoxide poisoning, dizziness and nausea, when this symptom occurs, you should immediately open the windows for ventilation and temporarily turn off the heater.

German cars are generally designed with cast iron blocks with a large heat storage capacity, plus they are generally equipped with turbochargers.

A good water circulation system is required to dissipate heat, so it generally takes more than ten minutes to reach 90 degrees in severe cold weather, while hot air can be generated in three or five minutes of Japanese operation.

When the gear under Xiaoang's feet is opened, it is only distributed to the wind under his feet, and the exit for blowing glass is not closed! In this way, the hot air feels insufficient. Volkswagen design concept.

Yes, the gear you open is which one, and everything else is off. Individuals prefer the idea of the masses.

<> German cars with more T, crankcase ductile iron.

There are a lot of them, just from the comparison of the German and Japanese ones that have been used, it's not too much....In my family, the coldest time of winter is minus 178 degrees at night, and at the extreme, it is more than minus 20 degrees...I open the German self-priming water temperature in about 15 minutes in the morning to reach 90, and the water temperature will drop a little after turning on the heater, the heat capacity.

Big, so the hot air comes slowly, Japanese cars, naturally aspirated, crankcase aluminum alloy, the heat capacity is a little smaller, and the hot air comes quickly. The above is a technical estimate, and I haven't tried it specifically.

The warm air can already be felt, Mazda 3

All-aluminum cylinder block, after two or three minutes of driving, you need to walk about three kilometers to feel the temperature, Qoros 3, cast iron cylinder block, two or three minutes after landing, there will be warm air after walking for one kilometer. This is the solution of human ingenuity in self-sufficiency. The structure of the car is almost the same, it is not a question of which brand or country, it is a problem of temperature, don't dwell on what car series, do it yourself, wait for it, and the people who complain about the car are only frozen.

The water circulating inside the engine is heated and pumped to the dashboard.

Inside, there is a small water tank inside the instrument panel, and the water tank has hot water in it, which will be blower when passing by.

When it blows out, it becomes hot air. Car heater** is the temperature of the engine, so if the engine is cold, there is no heating! To start the engine, wait until the engine reaches the normal working temperature, turn on the heater before there is heating.

This is mainly related to the engine, some engines are more hot, and it will warm up faster.

Because the engine chosen is different, some engines will have a cooling function after they are turned on, and the warm air will be relatively slow, but some engines will speed up faster, so the warm air speed will be relatively fast.

Because the design in this regard is often very different, and it is also set according to the size of the interior space, it is often slower, which is also because the interior space is relatively small.

The speed of hot air is related to the temperature of the water. The water temperature of the engine does not come up, the warm air will not be hot, the engine runs at high speed when the cold car starts, and the water temperature rises quickly when the heat is large.

This should be compared according to the cost performance and value, because some cars are more expensive, and the configuration in it is also higher than that of cheap cars.

Because the performance of different cars is not the same, the settings for this aspect are also different, so some cars are faster and some cars are slower.

Because the performance is not the same between cars and cars. The configuration of a car with a fast warm air must be very advanced, so it is fast.

Because the heater system is different, the expensive car heater system must be more powerful, so it is faster.

The heat energy of the car heater is the cooling water. The reason for the slow heating is that the engine has just started and the water temperature is not hot. As soon as the water temperature rises to 90 degrees, the warm air is normal.

If you use a heater, you don't need to turn on the AC switch. The AC key is the refrigeration key for the empty switch of the car. Pressing this key will make the compressor work and start blowing cold air in the travel pants.

Precautions when turning on the heater Do not sleep in the car: Just like the principle of liquid operation when the air conditioner is turned on, when the engine is working, if the fuel burns incompletely, it will produce high concentrations of carbon monoxide. When the car is moving, the air in the empty car can be replaced by convection through the air conditioning equipment, so the carbon monoxide concentration is very low.

Don't smoke in the car: When the heating is on, the car is an empty and closed room, which is prone to bacterial growth. Smoking in a car is inherently harmful to health.

Both first-hand smoke and second-hand smoke are inhaled. In addition, amines and nicotine from smoke and dust can adhere to the vaporizer surface. In the case that the empty switch is not used frequently and it is rainy and rainy, the bacteria will spread wildly on the surface of the evaporator, and when the air switch is turned on again, it will cause the air pollution in the car.

1. Warm up the car first and then turn on the heater: in winter, start the engine to preheat first, wait for the engine temperature pointer to the middle position, turn on the heater air conditioner, and at the same time set the air circulation to the external circulation, so that the cold air in the car is excluded from the car, wait for about 2 minutes, and then set the air circulation to the internal circulation, so that the temperature in the car can rise rapidly!

2. Use natural wind appropriately: natural wind heating should first set the temperature, then press the off button, and use the external circulation. At this time, all the displays on the screen are gone, but the heating is still being sent, and the faster the car, the more heating will be enough.

3. Use automatic air conditioning: For medium and high-end cars, it will be easier to use automatic air conditioning for heating, and the vehicle does not need to be preheated, and the heating comes relatively quickly. The only drawback: due to the fact that the air conditioning compressor is to be turned on, fuel consumption will increase to a certain extent.

The reason for the slow heating of the car heating air: the engine cooling system has air resistance, which leads to poor circulation of the cooling system, resulting in the slow failure of high water temperature and warm air heat; Clogged warm air tank and filter or problem with air volume control mechanism; The water pump is damaged, so that the flow through the small tank of warm air is not enough, and the heat cannot come up; The thermostat is always open or the thermostat is turned on too early, resulting in the water temperature of the engine not rising, resulting in the slow heating of the warm air.

If the outside temperature is low, especially when the car runs, the cold air will quickly cool the antifreeze, and the water temperature will not be hot. The impeller of the water pump is damaged and lost, so that the flow through the small water tank of the warm air is not enough, and the heat will naturally not come up; Engine air resistance causes poor circulation in the cooling system, resulting in high water temperatures, which can also lead to unheated warm air.

The heat energy of the car heater is the cooling water, and the reason for the slow heating may also be that the engine has just started, and the water temperature is not yet hot, as long as the water temperature rises to the water temperature of 90 degrees, the heater is normal. It may also be a piping problem, and the specific situation needs to be looked at on a case-by-case basis.
