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.
Replacing the Lada Granta heater radiator
If it's cold in the cabin when the heater is on, it means it's time to repair or replace the heater. Among the most typical reasons why you have to change the heater radiator on a Grant:
- clogging of channels due to the formation of scale or dirt;
- the occurrence of cracks or holes in the heating system.
In some cases, it is possible to get by with repair and restoration measures. For example, before changing the radiator, you can try flushing the system with a special liquid. There are means to get rid of scale inside the heating system, both by draining the antifreeze and the coolant inside. Such products, as a rule, do not harm sealants, gaskets, hoses, etc.

What is needed to replace a stove radiator?
When starting to replace the radiator, you need to prepare:
- set of clamps;
- sealant;
- antifreeze;
- Phillips screwdriver;
- key to 10;
- insulation (foam rubber);
- file.
Of course, you should purchase a new radiator in advance, and a “original” one, since the heat exchanger of other models will not work.

Sequence of steps when replacing a radiator
Work on dismantling the old radiator can begin from the engine compartment. Here, to create access to the elements of the heating system, it is necessary to remove the battery, the air duct pipe between the throttle assembly and the air filter, as well as the air filter itself.
Then you need to empty the system of coolant by draining it into a previously prepared container. Obviously, if a car owner intends to fill in new antifreeze at the end of the work, the old one does not need to be saved.

Before replacing the heater radiator of a Lada Granta car, you must remove the battery and air filter
The next stage of work is carried out from the interior. To gain access to the heater radiator, you will first have to remove the gas pedal: without this, it is not possible to remove the heat exchanger . Dismantling the pedal, as a rule, does not cause any difficulties: using a 10mm wrench, unscrew the three fastening nuts and disconnect the brake light limit switch and the connector for the electronic gas pedal. In addition, you need to press the brake pedal and lock it in this position.
Next, the plastic cover covering the radiator is removed, after which access to the heat exchanger opens. After this comes the most crucial moment - sawing off the radiator pipes: you should saw off after bending so that the cut part can be removed through the hole into the engine compartment. After both pipes are removed, you can remove the radiator from the niche into the car interior.

The pipes on the new radiator should also be sawed off so that later hoses can be put on them and secured with clamps. The cut edges of the pipes should be processed with a file, the holes in the engine compartment are filled with foam rubber to provide additional fixation to the structure and to preserve heat in the cabin.
Before disassembling the entire panel on the Grant, you need to file down the aluminum tubes on the stove radiator and connect the new radiator with a piece of hose... Doing this is not a problem, but before doing anything, you need to think about how to do it correctly.

It is more convenient to carry out the work of replacing the heater radiator together: one supplies the pipes from under the hood, the second receives them in the cabin. Sealant should be applied to the pipes of the new radiator and, after connecting to the flexible hose, securely secured with clamps. After this, you need to assemble all the removed parts: gas pedal, battery, air filter, then fill the system with antifreeze. At the end, you should check how the new radiator works: you need to start the engine and let it run for a few minutes, then visually make sure that the antifreeze level has not dropped, there are no leaks, and the heat exchanger has warmed up.
There are no fundamental differences in the procedure for replacing the heater radiator on a Lada Granta with and without air conditioning (unlike replacing the cooling radiator).

Stable and uninterrupted operation of all vehicle systems can be achieved by constant monitoring of their condition. The serviceability of the Lada Granta heater radiator becomes especially important in winter, therefore, in the process of preparing the car for the cold season, it would be useful to check its readiness for the season, especially if the vehicle is expected to operate at a high intensity in winter conditions. Practice shows that with proper operation, a stove radiator can serve properly for many years, but if it still fails, it is quite possible to replace the heat exchanger yourself.

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.
Radiator from Datsun with removable pipes
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.

| 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.
Lada Granta has become a really popular car. And, in many ways, this happened thanks to the affordable price and good components. For example, the stove installed on the Lada Granta is quite good, as it warms up the interior to the required level very quickly. AvtoVAZ engineers did a very good job on this issue, since for our harsh winters the issue of high-quality heating of the interior is very relevant.
