The Chevrolet Aveo stove doesn’t work – what to do
Heat in the cabin of any car – the key not only comfortable driving, but also road safety. After all, the temperature in the cabin affects the well-being of the driver. Therefore, at the first sign that the inside of the stove does not become warmer, it should be, without delay, to start the search for a malfunction.
When winter comes, doing something and looking for reasons in a cold car will be reluctant. Absolutely similar should be done in the summer, because who is pleased to ride in the heat with a full-power stove? Chevrolet Aveo is very popular with Russian motorists.
The most popular generation in our country (and all over the world) is the T250 generation. But there are no perfect cars. Among the various faults there are also problems of heating.
And here, too, there are situations when the Chevrolet Aveo T250 stove is not working. It should be noted that often on the forums there are complaints about the poor performance of the heater. Motorists do not understand why Chevrolet Aveo does not operate a stove.
The reasons here are quite standard. First, before starting work, you should immediately understand the essence of the heating system of any car. Then it will become clear why the chevrolet Aveo does not work stove.
The heating system on modern cars is connected with the cooling system. The tosol enters the heater radiator, which is blown by a fan. The heated air is sent to the cabin.
So we don’t have a Chevrolet Aveo stove. The reasons may be: – malfunction of the thermostat;
Breakdowns associated with the heater radiator; The air flow distribution mechanisms are not working properly;
None It should be noted that the problems with the heating system in modern cars are almost identical, and the algorithm of actions is the same.
Differences appear only in the location of nodes and units to be checked.
Preparing for work
All work to fix the malfunctionof of the stove should be carried out only if the engine and its auxiliary units related to the cooling system are healthy. To do this, you need to check the level of tosol in the expansion tank. It should be no lower than the minimum, the engine itself should be easily started and warmed up to the working temperature. Often there are difficulties at the last point.
It is a device that regulates the engine’s thermal mode and allows it to keep its temperature in a narrow range. The stove, like the engine, also works effectively only with a hot engine.
Therefore, if the engine does not warm up, the stove blows cold air.
The thermostat is diagnosed quite simply. After starting the engine, you need to feel the thick tubes going from the thermostat to the radiator. As they warm up, they should become hot. If the top warms immediately, then the thermostat is jammed in an open position. In this case, the engine will never warm up to the working temperature, because the tosol immediately goes to the radiator, cooling there. Accordingly, the heat exchanger of the heater will not be hot either. If the hoses remain cold after the warm-up, it is bad. The tosol does not get into the radiator and the engine overheats. In both cases, a thermostat needs to be replaced.
Often, when the cooling system works because of its leakage, the air, which has the worst thermal conductivity, gets in. Then chevrolet Aveo does not work stove or starts to work worse. This often happens because the tosol was poured into an empty tank, and the air got into the hoses without being pushed out.
The air cork is removed quite simply. It is enough to drive the front wheels on any elevation and turn away the plug of the expansion tank.
Then run the heated motor and rhythmically compress and squeeze the tubes leading to the tank. The tosol will gurgle, and the extra air – to go out. From time to time it is necessary to pour tosol.
Then wrap the cork and check the operation of the stove. The problem is also the leakage of the cork, which should create excessive (but not too much) pressure. Often it can be fixed by several faults at once.
Problems with the stove radiator
Often the reason why the Chevrolet Aveo stove is not working is the clogging of the heater’s heat exchanger. It is clogged with dirt, sediments from the engine cylinder block, rust and does not warm up as it should. Cleaning here is practically useless. Since it is necessary to remove the radiator, it will be wiser to replace it.
Engine engine malfunctions
Another common reason why the Chevrolet Aveo does not operate the furnace is purely electrical faults. Initially, cold air is pumped by a fan on the stove radiator, which then goes into the cabin.
A special flap directs this air through the radiator or bypasses it. Therefore, if these nodes malfunction, the air will not blow at all or is sent equally cold at any flap position. In the first case, the fan engine does not work.
In the second – faulty cable drive flap. If the motor breaks, the search for a problem should start with the fuse responsible for this chain. If it is not broken, then the wiring is faulty, or the electric motor itself, to be replaced or prophylactic cleaning.
To remove it, you need to dismantle the glove compartment. The engine is located at the bottom of the heater body and is held on snaps. To repair the flap drive, you will need to remove the bottom of the console.
Resistance block malfunctions
The fan’s electric motor works with multiple speeds.
A separate resistance unit is responsible for this, slowing down the rotation. If it malfunctions, the engine will operate at separate speeds or only at top speed, directly, without resistance. In this case, the most reasonable would be to replace the resistance block. As a result, warm air blows from the flap again.
Control unit malfunction
The control unit can also fail or incorrectly regulate the cabin temperature. Its malfunction is one of the reasons why the stove is not working (“Chevrolet Aveo is no exception). Faulty regulators on the panel may also be misacting. The control unit itself is rarely repairable and replacing. Another reason for the incorrect operation of the stove is the failure of the air temperature sensor in the cabin or its closure. In this case, the stove will always “fry” at full or blow cold air. After all, feedback occurs through this sensor.
Thus, figuring out why the Chevrolet Aveo furnace is not working is not such a difficult job. Knowing the device and how the system works, as well as presenting a sequence of actions, you can confidently deal with this malfunction yourself.
The presence of a heating system in modern cars used in our country is not only an attribute of comfortable operation, but also a guarantee of safety for motorists. If the stove does not work in Aveo, the glass quickly freezes, significantly reducing visibility.
Repair the fan (motor) of the Chevrolet Aveo stove.
Before you undertake the repair of the heater on Aveo, you need to know its working principle and design. The main elements of the heating system are these components:
- Directly the radiator unit
- air flaps;
- a complex of transporting air-driving systems on which heated air circulates;
- pipelines in which the coolant (tosol/antifreeze) circulates;
- A fan stove used to pump air masses into the piping leading to the cabin.
Failure of some of the elements can completely deactivate the performance of cabin heating as a whole. For example, when a stove fan doesn’t work in a Chevrolet Aveo T250, it is not possible to distribute the forced warm streams. The radiator is located directly behind the front panel of the cabin, closer to the engine compartment.
A pair of tubes approaches the radiator, one of which comes antifreeze, and the other goes back to the block. Thus, the high temperature is relegated from the DVS and partially goes to increase the comfort in the cabin.
Important! If the Fan of the Chevrolet Aveo stove is not working, you can’t get an effective return, so you need to monitor the performance of the site.
Circulating antifreeze takes heat energy from the heating area located in the combustion chamber. If you block its movement on the radiator of the heating system, it blocks the heat exchange and the transfer of heat inside the car. When the open contour of the stove circulates heated antifreeze, he manages to warm up the air from the radiator ribs. The stream is directed to the deflectors at the expense of the stove fan. The scheme has proven to be effective. Initially, at low outdoor temperatures, especially below zero, antifreeze circulates in a cool way. This does not contribute to the heating of the surrounding air, but leads to the saturation of the surrounding space with condensation. Due to high humidity, the corrosion of the radiator walls and the formation of windows are increased. Gradually, the temperature of the coolant in the contour rises, the cabin warms and the windows, including the windshield, thaw.
Over time, there are breakdowns in the car. Most often, faults are caused by improper operation of the system or non-compliance with maintenance rules. In addition to what can mess the motor of the Chevrolet Aveo stove, there are such troubles:
- The intercostal radiator space is clogged;
- There are leaks in the tubes;
- Failure of the heating control unit;
- The crane has broken down;
- The pump stopped pumping the liquid;
- There was an air traffic jam in the contour;
- A fan can be heard squeaking on the Aveo T300;
- The extra resistance burned out;
- you can be heard creaking and gnashing while working.
Many problems the motorist will be able to bring into working condition on their own. It is enough to buy new parts, for example, the engine stove Aveo T300 or T250.
How to repair
In some cars from the side of the heater there is a characteristic whistling sound. It occurs regardless of external weather factors. This manifestation is related to the features of the node design. The engine of the classic factory stove installed in the Chevrolet Aveo does not use rolling bearings. Instead, there are brass sleeves that act as slip bearings. During the period of operation there is wear and tear of the rubbing surface of the copper alloy, which leads to the appearance of brass dust. To eliminate the creaking fan stove on the Aveo T300, you can buy a new engine that is sold along with the body. However, it will be an expensive purchase, so motorists prefer to carry out independent repairs. Step-by-step algorithm:
- We dismantle the glove compartment together with a plastic casing located further;
- Remove the protective cap from the motor body;
- Using compressor tubes, we prune the bottom part where the rotor enters the sleeve;
- The process is completed after the brass chips have been completely removed;
- fill the medical syringe into several cubes with a small amount of SMT or ER additive, about 10-15 ml.;
- pour the lower sleeve.
It is not recommended to use motor oil for such an operation. It’s not enough for a long time.
Usually the creaking of the stove fan on Aveo is eliminated quite quickly. You only need to use the right lubricant, which will last a long time.
Today, increasingly, owners of low-cost cars prefer to carry out standard repair procedures on their own. First, the design of aveo-class machines is simple, and secondly, independent repair of nodes helps to save significantly on the services of service stations specialists. Worried about the comfort in the cabin, drivers begin to replace the stove, without even specifying the specifics of this procedure for the existing brand of cars. And for Chevrolet Aveo there is a way of working with the stove and heating system.
How the Chevrolet Aveo stove works
The Chevrolet Aveo stove (or heater radiator) in the interior of the car is responsible for the comfort of the driver and passengers. The health of people also depends on temperature conditions and humidity. Therefore, drivers pay a lot of attention to the health of the stove.
However, after a long use of the device, the heater radiator begins to flow. And this leads to the fact that the cooling liquid from the system can get into the cabin. This, of course, is not the most pleasant “surprise”: the tosol (antifreeze) begins to smell, and weather the smell can be quite difficult.
The main function of any car stove is to provide warmth in the car. According to GOST, in the freezing cold -25 degrees inside the cabin should be at least 16 degrees. These are the optimal performance of the working stove and on the Chevrolet Aveo.
The stove on “Aveo” works in different modes, depending on the driver’s preferencesTo prevent undesirable consequences and heat leakage from the cabin, the driver should minimally navigate the device of the heating system and stove. The design of the stove block itself is not cunning. The idea behind the device is that the heat in the cabin comes from the heated engine. The water pump drives antifreeze all over the system. When heated, the liquid enters the stove radiator. It heats up quickly (drivers often compare its action with a regular battery). When the radiator is heated, a fan is turned on, which drives out the hot air and blows it directly into the cabin. Antifreeze, after passing through the stove, again returns to the engine and so in a circle.
The first stoves appeared in American-made cars in 1917.
How to find a fuse from the stove
The trick of Chevrolet Aveo’s design is that it is equipped with two blocks of fuses at once. The first is located on the left side of the torpedo and you can get to it through an open driver’s door. And the second, which just places the right fuse from the stove, is mounted under the hood, at the top of it. The main landmark is an expansion tank.
The fuse block on the Chevrolet Aveo is easy to find by opening the hood – the device is located next to the wide tankIn order to find the fuse from the stove, it is necessary:
- Open the hood.
- Find a block of fuses.
- Brush the lid by pressing on the special retainers on the sides of the casing.
- On the inside of the lid is a diagram of the location of each of the car’s fuses.
- The health check of the element is carried out visually: the magnetic thread should be intact, contacts are not oxidized.
By “repairing” your fuse with conventional wire, you run the risk of making a short circuit in the electric grid.

What heating radiator malfunctions occur on Chevrolet Aveo
There are not so many malfunctions at the stove on the Chevrolet Aveo car. All problems in the work relate to the formation of foreign noises or poor heating of the cabin.
Why it warms badly
One of the most common complaints of motorists to the stove “Aveo” is considered to be dissatisfaction with its poor performance. The stove seems to work, but the cabin in winter warms up for a very long time or does not warm up to the desired temperature.
There are two simple explanations for this problem:
- There is very little antifreeze in the cooling system, so the heat does not enter the cabin.
- An air jam was formed in the system when the new coolant was poured in.
Lack of coolant can cause problems of many devices in the car, including stovesThe first problem is solved very simply – banal slither antifreeze to the desired level. The second will require a little more time. The removal of air traffic jams is carried out in the following scheme:
- Twist the cork with the expansion tank.
- Start the engine.
- Warm the engine to working temperature.
- Sharply press the gas pedal.
Air bubbles should come out of the expansive tank under pressure of the gas pedal. However, with them there is a risk of losing some amount of antifreeze. But this is a minimal loss, and the problem with a poorly functioning stove will be solved.
After the excess air bubbles come out of the tank, it is recommended to pour the necessary amount of coolant.
The stove doesn’t shut down
Perhaps the most surprising “nuisance” with the non-switched stove on Aveo is that this option was originally planned by the manufacturer: Thus, for Chevrolet Aveo since 2007, not turning off the stove can not be considered a mistake or Malfunction.
On the new Aveo models, the stove shuts down automatically when the cabin temperature sensors are off.
A whistle can be heard while the stove is working
Characteristic whistling sounds during the heating radiator are a sign of the presence of a foreign object in the fan’s work area or the breakdown of its blades. Sometimes the whistling indicates that the bearings of the device have been developed.
Whistling sounds from the radiator area of the heater – it is not yet deadly. But if you put the solution of the problem in a long box, you may have more serious problems with the heating system in the car. To eliminate the whistling, you need to remove the stove, find foreign elements in it (a blade of grass, for example), clean it from the dust and install it back.
Usually it is enough just to remove the case from the stove to see the cause of the whistle.
How to replace the stove fuse on Chevrolet Aveo
The fuse can be replaced in a few seconds – the main thing, initially to choose the right element with the same characteristics as the old one. And the order of work corresponds to this scheme:
- Open the hood.
- Remove the lid from the block.
- Pull out the old item.
- If necessary, a soft cloth clean the landing site from the dust and dirt.
- Install a new fuse.

Fuses on “Chevrolet Aveo” cost a penny, so experienced drivers often buy several items at once, so that even in the event of road failures to be able to quickly restore the operation of the stove.
How to remove the stove from Chevrolet Aveo
The first step is to prepare a set of tools that you will work with:
- two ratchets (you can do one, but it’s technically more complicated);
- Head on 10;
- Head on 12;
- thread fixer (you’ll need it when you install a new stove).
Before you start any work, you need to disconnect the wire from the sub-zero terminal of the battery – so you will create a safe environment to replace the stove.
Disconnection of power wire from the terminal “minus” is recommended in the performance of any work related to electronic devices and systemsNext it is recommended to perform work strictly according to the scheme:
- To dismantle the central console of the heater radiator (remove the casing of the stove from the cabin).
- From the torpedo remove all hinged devices (glove compartment, inserts on panels, tether flaps, linings, block with clock, etc.).
- When dismantling, you should immediately mark all the harnesses with wires, as when you reassemble, you may find confusion as to which wire should be connected.
- Then you need to disconnect the beam from the radiator case. The stove is fixed on the beam with a single bolt, but because of its length and possible rust will have to spend a lot of time on dismantling.
- To remove the torpedo stove, you need to pull it on itself and pull out of the cavity of the dashboard.
- Then you will need to unscrew six bolts fastener to the body and six bolts in the steering area – the only way you can remove the beam and the existing control unit of the stove.
- Next, twist two long bolts, by which the stove unit is fixed to the air conditioning unit.
- After that, you need to open the hood and remove two thick tubes, which are directed to the radiator of the stove.
- From the cabin you will need to twist four bolt connections between the stove and the body.
- This will remove the stove block itself.

Removing the torpedo is the most difficult – you will need to carefully remove from it all attachmentsDisconnecting harnesses and terminals, you need to sign each wire to avoid further errors when connectingThe new heater radiator should be the same marking as the old
After that, you can start editing.
Installation of a new heater radiator
If you remove the stove from the Chevrolet Aveo – it is not an easy task, then to install a new one – even more difficult. It’s not about the complexity of the hardware or the use of small parts (they are not), but the ability to properly connect all the wires. If you make a mistake with the place of connection at least one harness, you can get incidents in the work of the stove or even a closure in the network.
Therefore, it is recommended to carefully and carefully sign/photograph the nature of all connections to avoid possible malfunctions immediately after installation. The new stove is installed in reverse to remove the sequence. Before installing the device, you need to clear the landing area from dirt and traces of antifreeze leaks.
Video: Detailed instructions on replacing the stove
It is possible to replace the heating radiator on Chevrolet Aveo on your own, but it is quite difficult without the knowledge of mechanics and electronics. In most cases, to save on the services of specialists, the owners themselves dismantle the stove from the cabin and ask the service station just to properly connect the new device.
