There may be various malfunctions in the operation of the climate system of Lada Granta and Lada Kalina cars. One of the common problems is when the stove blows cold or barely warm air. We will understand the causes of this ailment, and will also tell you how you can improve the design of the heater.
Pouring sealing liquids
When any leak occurs in the cooling system, many car enthusiasts fill in various sealants. But these chemicals can not only eliminate the leak, but also cause great harm. For example, they can clog the stove radiator.
One of the options for bringing the heater radiator back to life is to consider a complete replacement of the antifreeze in the cooling system. Preliminary flushing of the system will be required. If this procedure does not help, then there is no other option but to change the heater radiator in the Lada Granta interior. This is far from a simple and exciting activity, as some car owners think.
Cabin filter
The cabin filter is responsible for the frequency of the air ducts, protecting the fans and radiator from contamination. Often, many car owners remove the cabin filter to create a more powerful air flow from the air ducts, which soon leads to contamination of both the air ducts and the radiator with fan.
If there is a weak air flow from the heater, then most likely the cabin filter or heater radiator is dirty.
Air in the system
What to do about airing in the system?
- Find a hill with a slope of at least 30%.
- Place the Lada Granta on it with the front facing up.
- Warm up the engine to operating temperature (approximately 85 degrees).
- Squeeze the hoses vigorously until air leaves the system.
As a result, the car should become warmer.
Troubleshooting
If the heater on your car stops working, you need to check the serviceability of not only the heater itself, but also all other devices included in the heating and cooling system. The failure of any link provokes a failure of the entire system or its individual part. Experienced car owners recommend not to wait for a problem to arise, but to periodically arrange preventive examinations for your “iron friend”, then you can prevent undesirable consequences.
If the stove begins to supply only cold air into the cabin, the following may be the trigger:
- insufficient coolant level;
- poor thermostat performance;
- the damper does not close completely;
- a broken fan;
- burnt fuses or resistor.
It is for this reason that it is useful to have your entire heating and cooling system inspected.
Restoring the heater
First you need to check the coolant level. It should not be lower than what is indicated by the manufacturer. The manufacturer indicates two critical levels on the expansion tank: maximum and minimum. The liquid should not go beyond these two boundary states. A low level of coolant provokes a decrease in pressure inside the cooling system, in this case it is very stupid to hope for excellent operation of the stove, and accordingly, there is no point in counting on the fact that the cabin will become warm.
As soon as the level drops, the owner must top up the coolant used. Mixing antifreeze and antifreeze should not be allowed. Otherwise, a chemical reaction may occur, causing the radiator to become clogged with sediment. An excessively dirty radiator will interfere with the normal operation of the stove.
If you actually find a dirty radiator, we recommend that you wash it. You can purchase special chemicals, pour them inside the device, and also clean the upper surface of the radiator using such products. Often drivers, noticing a radiator leak, decide to quickly solve the problem. To do this, they go to an auto store where they purchase sealant. Of course, the sealant can be considered as a real “savior” if there is a leak along the way. However, it must be used if other methods of eliminating leaks are not available. The sealant plugs the holes, stopping the leak, but at the same time it also clogs important parts of the radiator, as a result of which its performance decreases.
Sometimes the thermostat fails, or rather, its valve begins to work incorrectly. For this reason, the circulation of the liquid is disrupted; accordingly, it cannot warm up normally and ensure the successful supply of warm air to the car interior. It’s easy to check the version of a failed thermostat. Start the stove and continue driving along the route you need. At this moment, if the thermostat is faulty, the stove will “go on strike” and refuse to heat the interior of your Lada Granta. As soon as you get stuck in a traffic jam or stop on purpose, as if being in forced downtime, you will notice that your stove will simply begin to “boil”. However, having resumed movement, the stove will again begin to cool quickly. Having noticed such “oddities” in your heater, you can be absolutely sure that you need to change or repair the thermostat.
Thermostat has failed
Another reason when the stove on a Lada Grant does not heat well is that the thermostat has broken. How to determine a malfunction, by what signs? When the engine is warm, the antifreeze does not warm up above 76 degrees when the air intake damper is open. In this case, only a complete replacement of the thermostat will help.
The standard thermostat installed on the Lada Grant opens at a temperature of 85 degrees. In automotive stores you can find thermostats that are designed to operate at a temperature of 92 degrees. Therefore, according to theory, the interior of the Lada Granta should become warmer in winter.
The main reasons why the stove does not heat on Grant (video)
The stove belongs to the heating, air conditioning and ventilation system of a car. The purpose of its work is to maintain a given temperature and humidity conditions, ensuring comfortable conditions for being in the car and an influx of fresh air. The type of ventilation system in Grant is supply and exhaust. The stove is controlled by simple controls that allow you to change the speed of air flow, its temperature and the direction of blowing: onto the windshield, into the legs, etc. To isolate the interior from unpleasant odors and faster warm-up in winter, an air intake switch for the stove is provided from outside or from the inside.
Signed up with another dealer
I will not name the city in which I again made an appointment with the showroom specialists from AvtoVAZ. The time was set for 8 a.m. to allow enough time for repairs. After lunch they called me and said that everything was fine with the car. This is normal operation of the stove.
I did not agree with them and began to prove that this could not happen. Explained what they did in the previous service. But the masters did not want to take measurements on another car. This was also the end of the matter at the second car dealership.
Additional Tips
However, it also happens that the problem with heating the interior consists only of some small mistakes. Therefore, before you start disturbing the service center workers, check whether all the dampers on the stove are set in the required position. It wouldn’t hurt to tug the hot air damper a little.
There is a possibility that it is simply stuck. And, with a significant push, it will be moved from its place.
Often, car owners do not particularly monitor the condition of their car, which can result in various problems. For example, the stove heats poorly or cold air comes out of it. Why? This means something was overlooked somewhere. But don’t be afraid, you can carry out the repairs yourself. But first you need to find the cause of the breakdown.
Check the refrigerant level
You need to start by checking the antifreeze or antifreeze. Such an inspection should be carried out as often as possible; this can save you from many problems in the future.
Attention.
If a leak is discovered, you need to place a sheet of cardboard under the engine overnight, and in the morning you can determine the problem area. But keep in mind that this method only works if the leakage is severe. Otherwise, a more thorough inspection will be necessary.
Let us remind you that in the previous article we told you how to clean injector nozzles with your own hands. This procedure is especially relevant today, when the quality of fuel leaves much to be desired.
First you need to check where the leakage is possible.
1. Check how intact the expansion tank is.
2. Pay attention to the thermostat connections, which have three hoses carrying fluid.
3. Inspect the coolant inlet and outlet hoses to the passenger compartment opposite the engine.
4. Inspect the cooling radiator.
Attention.
If the leak is small, then you can simply let the engine cool and run your fingers along the bottom of the pipe joints.
1. Tighten the clamps.
2. Replace hoses if cracks are visible.
3. Add antifreeze and check how the stove now works.
Attention.
If your car is not the newest, it is better to use antifreeze as a coolant, since it is less fluid, unlike antifreeze.
Blockage in the system
Often an antifreeze leak is accompanied by a “plug” in the cooling system. Then the coolant enters the radiator irregularly, causing the heater to weaken.
To solve this problem, you need to open the tank, remove the radiator cap, warm up the engine, step on the gas, and raise the speed to 3500 rpm. Then the blades will direct the liquid at a higher speed and the plug will come out.
The problem with a poorly functioning stove may lie in the thermostat. When the engine warms up, there is a damper inside it that opens at a certain temperature. When this happens, fluid flows through the radiator, cooled by the fan. Over time, the damper can deteriorate, causing the engine to overheat and the heater to blow cold air.
The thermostat is located at the bottom left of the engine. Three pipes go to it. When the arrow on the gauge reaches the red mark, touch the thermostat (with a glove). If the hose that comes from it is cold, then the damper is broken.
Attention.
You can revive the thermostat using a handy method: take the key to 17 or 19 and lightly tap on the bottom.
There are many channels in the radiator that can become clogged, resulting in reduced heat transfer. You can purchase a new radiator or clean the old one.
Attention.
It is recommended to clean the circulation regularly every 2-3 years.
The heater tap can easily jam. With the first frost the problem can be identified. In this case, the tap simply does not switch to heating mode. Here, only replacing the tap will save you.
If air does not flow from the drainage system at all, then either the damper cables have fallen off or the motor has burned out.

| 1. | Vladimir: Six months have passed since we bought the car, and there have been no breakdowns in such a short time. The fan refused to start several times, the reason turned out to be a bad fuse contact. |
| 2. | Vasily: I have been actively using the machine for two years, there are no particular complaints, all units are working as normal. Breakdowns happen, like everyone else, but they are minor and can be easily fixed on your own. |
| 3. | Gennady: after two months of the machine being idle, the stove heater began to supply little air. I disassembled it myself, cleaned it, works properly. My recommendations to car enthusiasts: don’t be afraid to repair them yourself. |
| 4. | Kirill: I think that Granta is put together with high quality, the price is affordable for a family with an average income. Provided timely maintenance, no problems arise. |
| 5. | Ivan: after buying the car, I immediately drained the factory antifreeze and bought good imported antifreeze. Now I don’t know any grief, the stove works like a charm. |
| 6. | Dmitry: there were minor defects, I fixed them myself, but they were insignificant and did not affect the performance of the machine. |
| 7. | Igor: I’m happy with the car, there are no major comments, as for domestic transport it’s very good. |
| Negative | |
| 1. | Victor: Over the two years of active use of the car, I contacted the service station several times under warranty. The fan malfunctioned, then the stove heater. Decided to renovate and sell. Renault Logan is several times better than its domestic counterpart. |
| 2. | Vladlen: I’m dissatisfied with Grant’s purchase, I’ve already regretted wasting money several times. The car is not worth the investment. |
| 3. | Gennady: a year and a half since purchasing the car, constant investments, purchase of consumables, repairs at service stations. |
Conclusion The stove heating system of the Lada Granta is completely copied from the Lada Kalina. There are no complaints about the equipment, everything works properly. In order for the mechanism to serve for a long time, it is necessary to systematically carry out inspection and prevention.
Many motorists save on maintenance, as a result of which the service life is reduced. An important factor is the cloudiness of the antifreeze. The manufacturer recommends replacing it every 75,000 km. Exceeding the interval causes deposits to form at the bottom of the radiator and corrosion begins.
Additional Tips
However, it also happens that the problem with heating the interior consists only of some small mistakes. Therefore, before you start disturbing the service center workers, check whether all the dampers on the stove are set in the required position. It wouldn’t hurt to tug the hot air damper a little.
