Grant stove radiator
The location of the heater radiator on the Grant is not convenient for replacing it. To remove the radiator without damaging it, you will have to dismantle the dashboard, which can take a lot of time and labor due to a trivial problem that can be solved in an hour in other cars.
The radiator is located under the dashboard in its central part at the driver’s feet. Its pipes are hidden behind the decorative side panel trim. This location of the radiator makes it a little difficult to access it when replacing it, but if you use the correct replacement instructions, then removing and installing the radiator yourself will not be difficult.
Troubleshooting methods
Heating the car interior directly depends on the proper functioning of the engine cooling system, since the air entering inside is heated when passing through the radiator of the Lada Granta stove. It is necessary to check the coolant level in the expansion tank: a decrease in the amount of antifreeze leads to impaired circulation and insufficient heat exchange. This result may also be due to a leak in the valve on the expansion tank plug.
Insufficient heating occurs due to a malfunction of the thermostat or pump in the engine cooling system. The cause of unsatisfactory performance is sometimes an air lock in the heating system. To eliminate it, with the engine warm, remove the heating hose from the throttle valve assembly. Then you need to create excess pressure in the expansion tank - unscrew the cap and blow into it. In this case, coolant containing air bubbles will flow from the removed hose. Similar actions must be performed with the second hose. This operation should be carried out with great care: antifreeze on a warm engine has a temperature of about 90°C, and when removing the hoses you can burn your hands.
The stove stops heating due to a malfunction of the gear motor that controls the damper that regulates the air temperature. Replacing the VAZ 2190 heater gearmotor can be done with your own hands, however, this is a rather labor-intensive procedure that requires professional experience. The part is located under the hood of the car, and to remove it you will need to dismantle the seals, frill, wiper arms and trapezoid. When replacing a nano gearmotor, it is recommended to check its performance by applying voltage to the corresponding terminals from the battery.
Important elements of the stove design are the heater radiator and the fan that supplies air to it. The heat exchanger must not be dirty, otherwise it must be replaced or repaired.
How to identify a clogged radiator
Checking the radiator is a fairly simple task that anyone can do. To do this, you need to check the circulation of fluid through the radiator. If the circulation is normal, then both radiator tubes will be hot, but if the inlet tube is hot and the outlet tube is cold, this indicates that the radiator is clogged from the inside.
A clogged radiator can be washed or, at best, replaced with a new one.
Types of Grant stove radiators
There are two types of radiators: with soldered pipes (factory radiator) and with removable ones.
Factory radiator with permanent pipes
The manufacturer produces radiators with non-removable pipes, that is, in order to dismantle it without removing the entire panel of the car, it is necessary to saw off the pipes coming from the radiator.
It is best to purchase a heater core from Datsun On-Do. The dimensions of the Datsun radiator are no different from the Grant one, with the exception of removable pipes, which will greatly reduce the pain during installation.
Step-by-step replacement process
It is necessary to remove the battery, the air filter box by pulling it out from the rubber dampers and remove the intake corrugation. You will need this to access the thermostat.
We drain the antifreeze from the cooling radiator by unscrewing the plug in the lower right part of the radiator. To drain, you will need a container of at least 10 liters.
Attention: It is necessary to drain the coolant when the engine is cold to avoid burns.
Remove the connector from the electronic accelerator pedal and unscrew the pedal from the car body using a 10mm socket wrench. Then remove the pedal from the studs.
Unscrew the screws securing the radiator cap with a 6 mm wrench and remove it.
We remove the radiator pipes and lower them down so that the remaining antifreeze drains.
Now you need to press down the brake pedal; to do this, remove the cotter pin that secures the pedal and press on it when we remove the radiator.
If the radiator is not dismountable, that is, the pipes are not removable, they must be sawed off with a hacksaw. If the pipes are removed, they must be removed and pulled out of the holes in the engine shield.
After removing the pipes, you can pull out the radiator by pressing the brake pedal down.
We install the new radiator in the same way, pressing down the brake pedal, first removing the pipes from the radiator and installing them after the radiator is placed in its seat.
If the radiator is not prefabricated, then the pipes can be sawed off and the connection can be made on the hoses.
Adviсe
Antifreeze leaked into the cabin
To prevent problems with the heater core, you need to carefully monitor it. For example, from the first days of buying a car, periodically look under the car to see if there are dark spots there. And in the engine compartment it would be a good idea to observe the condition of the cooling system hoses. If you notice traces of antifreeze in any of these places, you need to immediately seek help, or carry out repairs yourself.
If possible, the hoses for connecting the heater radiator should be replaced with new ones, having coated the connection points with sealant. But some do not agree with this opinion. After all, sealant from the hose can get inside the cooling system and cause damage to the pump. As a result, the timing belt will break and the valves will meet the pistons.
A simple way to replace the heater radiator on Lada Granta, Kalina
If you decide to replace the heater radiator on a Grant or Kalina according to the factory instructions (for Granta - TI 3100.25100.20554, for Kalina - 3100.25100.20469), then you will have to remove the instrument panel (dashboard). However, the owners found an easier way to replace the stove radiator.
Attention! The Lada Granta FL uses a new heater radiator. It is oversized and has removable tubes.

| 1. | Vasily: for two years of operation there were no breakdowns of the heating system. Several times I noticed an antifreeze leak at the joints of the pipes. After replacing the clamp with a new one, there were no cases of depressurization. |
| 2. | Vladlen: Granta is assembled with high quality, the fit of parts is good, there are no comments. Provided regular maintenance, it will last a long time. |
| 3. | Gennady: for a year and a half of active use of the machine, I did not make any capital investments, with the exception of the purchase of consumables. I treat equipment with care, I buy only original parts. |
| 4. | Ivan: I recently underwent the fifth maintenance, the master assured me that the equipment was in good working order, there were no comments. |
| 5. | Dmitry: at 50,000 km, I replaced the return pipe once due to the formation of a crack. The system is operating normally, there are no complaints. |
| 6. | Ignat: my machine works like a watch, no complaints. I carry out technical inspections in a timely manner, fill with high-quality oils and high-octane fuel, and strictly follow the manufacturer’s recommendations. |
| 7. | Victor: It will soon be two years since I bought a Lada, I’m happy with the choice. My friends advised me to buy a Renault Logan, but I chose a domestic one. |
| Negative | |
| 1. | Ivan: I’m dissatisfied with the purchase of the Lada Grant; in the first winter, the antifreeze supply pipe to the radiator cracked. Fortunately, I noticed it in time and replaced it with a new one, otherwise the consequences could have been different. |
| 2. | Sergey: during the year and a half of operation of the car, the car underwent unscheduled repairs twice. I think this is too much for domestic transport. |
| 3. | Gennady: Now I regret buying Granta; Renault Logan is better. The car is falling apart every day. |
Conclusion There are difficulties when dismantling the stove heater. Many owners are familiar with this. At the same time, the “craftsmen” came up with a way to replace the heat exchanger without actually removing the dashboard, which significantly reduces time, money, and effort.
The final choice is up to the owner of the technical equipment. You should still listen to the recommendations of experts.
Trick when replacing the heater radiator on Lada Kalina 1
1. Unscrew the screws securing the clamps of the heater radiator pipes in the engine compartment.
2. Unfasten the brake pedal.
3. Remove the gas pedal. Remove three nuts. To unscrew one of them, you will need to remove the tin plate.
4. The pedal does not allow you to pull out the heater core. To do this, we make a hole in the stove body so that the radiator can be moved back.
5. Install a new heater radiator. We close the hole using a soldering iron and sealant.

Rules for using a standard heating system
The car's operating manual outlines the basic principles of operation of the ventilation, air conditioning and interior heating systems. To quickly warm up, you need to switch the damper to the air recirculation position and the fan speed to the “maximum” position. In this case, the car windows must be closed. You should not drive in this mode for a long time, as this can lead to fogging of the windows.
The main reason for the accumulation of condensation is the difference in temperature inside and outside and high humidity. To prevent the windows from fogging up, you need to warm them up by pointing the heater deflectors at them and dry the air by turning on the air conditioning. However, when the vehicle is driven under heavy loads (for example, on long climbs) with the air conditioning turned on, the engine may overheat, so in such conditions it is necessary to monitor its temperature. Condensation is usually the result of luggage blocking the vents.
Incorrect operation of the ventilation and heating system may be caused by a malfunction of the temperature sensor located in the interior lamp. It is not recommended to drive with the windows open in hot weather with the air conditioning running.
The vehicle's ventilation, air conditioning and heating system creates conditions for normal and comfortable driving in any climate zone. AvtoVAZ engineers developed and implemented a simple and reliable heating concept for the Lada Granta model. But for the system to operate effectively, certain rules must be followed, which will help avoid unexpected breakdowns.
