Replacing the heater radiator Lada 2101 (VAZ 2101)

Removing the heater radiator on a VAZ 2101-2107 and those models between (2102, 2103, 2104, 2105 and 2106) is not as difficult as it might seem at first glance, the only thing you need is to stock up on antifreeze or antifreeze, depending on what is filled.
I removed the heater radiator for the first time for a trivial reason: the heater tap was leaking. Replacing it involves removing the radiator completely.

Also, the reasons for removing the radiator may be due to the fact that the stove does not heat well, as was the case for me.

And it is possible that the radiator itself may leak, as my friend had, then you will have to buy a new radiator (preferably copper).

And these are the main reasons when it is necessary to remove the heater radiator on a VAZ classic.

Now let’s look at how to remove the heater radiator using the example of VAZ 2105 and 2107 (on other VAZ cars, the process is similar).

Replacing the stove on a VAZ-2101, 2102, 2105, 2106, 2107

Most often, a malfunction of the heater radiator is detected when a puddle of antifreeze or water forms under the feet of the driver or front passenger, or when you turn on the heater in winter, instead of warm air, you get a stream of cold air, and again a puddle of antifreeze in the cabin.

The reason for this is a leak in the car's heating system. The result of such a malfunction is a spoiled mood and cool temperature in the cabin. This problem can be easily corrected on your own. For some VAZ models it will take very little time - VAZ-2101, VAZ-2102. Replacing the stove in a VAZ-2105, 2106, 2107 will require more fuss; repairing the heating system on these cars is not much different, but things are a little more complicated with the radio panel. In this article you will find useful information and guidance on replacing the heater radiator of VAZ cars.

First of all, you need to find out the reasons for the malfunction of the car heating system:

1. Antifreeze leak. There may be several reasons for an antifreeze leak in the car interior; they can be identified by visual inspection: a rusted heater radiator, a metal pipe, or a heater faucet. If your problem lies in the stove pipe or tap, then they can be replaced without disassembling the central panel and radiator casing. In this case, repairs will not require much effort and time. If it happens that the cause of the leak is a rusted radiator, then there are two options to deal with this problem. If you have a copper radiator installed, then you can solder it and tin it. You can do this yourself if you have the necessary skills, or find a master. If you have an aluminum stove radiator installed, then it would be most advisable to replace it with a new one, since such radiators usually cannot be repaired.

Signs of a malfunction of the VAZ 2107 heater radiator

A malfunction of the heater radiator can be due to two reasons:

Coolant leakage from the radiator.
Clogged internal channels.

It is necessary to remove the radiator of the VAZ 2107 cooling system; if any of these problems are detected, after dismantling it is repaired or replaced with a new one. The replacement process itself is not very complicated; you need to be careful and careful. To replace the heater radiator you will need the following tools:

Key to 7;
Key for 10;
Crosshead screwdriver;
Rags;
Coolant;
two new rubber gaskets.

What does the stove consist of?

Before you start improving the stove, you need to understand what elements it consists of. Any VAZ stove consists of:

radiator;
air flow distributor;
three-blade or 5-blade fan and its shell.

If the theater begins with a hanger, then the stove begins with an air intake duct. It is located at the rear of the engine block. It is here that the air coming from the street is purified from moisture. The box is protected from a hot engine by special gaskets - they act as a partition.

After the air is cleared of moisture, it enters the heating system. The steam then comes out. There is a device above the dashboard that allows some of the air to escape when driving.

The heating housing is located in the interior of the car: it is fixed to the partition with the engine.

The heater radiator has inlet and outlet channels. These channels are connected to each other by tubes. The first tube has a built-in heating valve that regulates the supply of cooling liquid. Using a lever located on the dashboard, the flow of fluid into the machine's ventilation system is reduced or increased.

At the bottom of the radiator there is a heating system fan with a small motor that allows you to adjust the fan speed (there are two speeds in total).

The exhaust device allows the incoming air to be distributed throughout the cabin.

In order for the improvement of the VAZ-2101 stove to be justified, it is necessary to understand why the stove is not working well. If you are satisfied with your car, the stove is working properly, but you want to improve its performance, then it’s time to do tuning.

The stove doesn't heat

If the engine is warm, the heater valve is open, but cold air is coming from the heating system, then most likely the radiator is clogged or there is a low level of antifreeze in the cooling system. To check the coolant level, just look at the level in the expansion tank or unscrew the main radiator cap with the engine off. If there are no problems with the level, then you need to deal with the heat exchanger, you may have to flush it or the entire cooling system. To avoid possible clogging of the heater radiator, you should not add various additives that eliminate small leaks. Such products can easily clog the stove tubes.

Cold air flow from the heating system can also be caused by air in the system. In this case, you will need to remove the air plug and add coolant.

Airing is the appearance of an air lock in the cooling system during repair work or when replacing the coolant.

In addition, the problem is possible with the tap itself, which over time can become clogged or scale may form if water is used instead of antifreeze. If there is a problem with the tap, the part is disassembled and cleaned or simply replaced. Another, although rare, but possible cause of a cold stove, may be pump failure. In this case, the engine warms up, but the pipes going to the heater radiator remain cold. In this case, the water pump must be repaired immediately. Warm air may also not enter the cabin due to problems with the heater fan. The problem may be with the motor itself or its power circuit, for example, if a fuse blows.

How to change the stove in a VAZ 2107

Having found out that the heater needs repair, it will require complete or partial dismantling. If there is a problem with the motor, then it is enough to remove the lower part of the assembly. If there is a problem with the radiator, you must first drain the coolant from the engine cooling system. To carry out repair work you will need the following tools:

Phillips and flathead screwdrivers;
set of open-end and socket wrenches.

Heater removal

After the coolant has drained and the necessary tools have been prepared, you can begin disassembly. It is carried out in the following order:

Remove the negative terminal from the battery.
In the engine compartment, loosen the two clamps that secure the hoses to the heater pipes. When the hoses are pulled together, a small amount of antifreeze will leak out.

Unscrew the clamps and pull the hoses off the radiator tubes

Refinement by sealing joints

The first method is the simplest, but it will not bring big changes to the interior temperature. It consists of sealing the air outlets, so that air will flow better into the cabin.

This will allow you to optimally adjust the air flow, and the windows will be cleared of steam and icing faster. Sealing all existing connections helps to avoid unnecessary air loss, but this does not make the car any warmer.

If this modification is not enough for you, then it’s time to take the bull by the horns and tune the entire stove. It may sound scary, but in fact, modernization is not as difficult as it might initially seem.

Simple rules that, if followed, will extend the life of the heater radiator

In order for the radiator to last a long time, you need to follow a number of rules:

When purchasing, you should not save money and buy a low-quality unit. You should pay attention to the material of manufacture and the manufacturer.
Only high-quality liquids should be poured into the system. Do not pour water and mix antifreeze with antifreeze. No lubricant or fuel should enter the system.
When idle during the warm season, when the heater is not in use, you need to open the heater tap at least twice a month so that liquid enters the radiator. Thus, the unit will not dry out and the heater tap will not stick.

If you carefully operate the heating system and fill it with high-quality antifreeze or antifreeze, then its components will last for many years.

The first method is the simplest, but it will not bring big changes to the interior temperature. It consists of sealing the air outlets, so that air will flow better into the cabin.

Replacement procedure

You can buy a new heater radiator for a VAZ 2107 at any auto store; an aluminum one will cost about 1 thousand rubles, and a copper one will cost a little more, but it can be soldered, which, however, is only a temporary measure. The kit should include spare parts necessary for installation.

First you need to disconnect the battery terminal so as not to damage the car's electrical system during operation. Radiator installation begins with draining the coolant. To do this, use a 13mm head to unscrew the drain plug, which is located on the cylinder block; there is no need to drain the cooling system radiator.

Replacing the stove (heater) tap

The heater valve is used to regulate the flow of coolant through the radiator. In the warm season, there is no need to heat the interior, so the tap is most often in the closed position.

With the arrival of cold weather, we again remember the possibility of adjusting the temperature in the cabin, but sometimes we encounter unexpected problems: the heater tap (when liquid passes through it) can leak, oxidize and even jam (if not used for a long time). This part cannot be disassembled or repaired, so to restore the heating system, all that remains is to replace the stove tap .

What will be required for replacement?

New heater tap.
Two rubber gaskets for the heater valve.
Silicone high temperature sealant (red).

How to replace a crane on a VAZ 2101-2107 “classic”, “Volga”, “Niva”, “Oka” (work order)

The operations for replacing the heater valve on different cars are very similar and differ mainly in the need to dismantle some parts to gain access to the failed valve.

Note: the heater faucet from the Zhiguli also fits the Volga, Niva, and Oka cars.

Next, we will consider in detail the replacement of the tap on VAZ 2101-07 “classic” cars.

According to the instructions, before proceeding with the removal of the pipes, it is necessary to drain the liquid from the engine cooling system. This operation can be omitted, given the fact that the stove radiator and pipes are located above the level of the main radiator. It should be taken into account that some of the coolant will still leak out, so you need to have a small container on hand.

Use a screwdriver to loosen the clamps and remove the hoses from the heater radiator pipes. Do not forget to place a container under the hoses to drain the coolant leaking from the pipes.

Using a key “8”, unscrew the two screws and remove the seal from the radiator pipes.

Auto-stoves

The onset of the autumn-winter period makes many car owners remember the condition of their car heater. Few drivers take care of the normal operation of this important part in advance. And even then, this often happens in cases where a puddle of water or antifreeze suddenly forms under the feet of the driver or front passenger, depending on what is in the cooling system.

As a rule, the main reason for such a sad phenomenon is a leak in the car’s heating system. However, most often a malfunction of the stove radiator becomes obvious to the driver only in the cold season. When you turn it on to “warm”, it turns out that the heating is not working, or antifreeze appears in the cabin. I have to change the radiator. How can you do this yourself?

The process of replacing the heater radiator on many cars of the VAZ-2101, VAZ-2102, VAZ-2105, VAZ-2106, VAZ-2107 models is very similar and is not very difficult. Before this, you can drain the coolant from the engine block, but this is not necessary, since the losses will be insignificant. You only need to have 1 liter of coolant in stock. The whole process looks like this step by step:

From the engine compartment, unscrew the two clamps on the radiator pipes and tighten the hoses.
Unscrew the fasteners of the rubber seal and remove it.
In the car interior, remove the radio panel.
Using a “7” key or a screwdriver, unscrew the fasteners of the heater tap drive cable and disconnect the cable from the tap.
We find four spring clips on the fan casing and remove them using a screwdriver.
We lower the casing down and move it to the left. To remove the casing completely or move it further you will not be given the power wires for the electric motor.
Pull the heater radiator out of the casing.

If the radiator cannot be repaired, we replace it, and twist the tap and tubes to a new one. Assembly is carried out in reverse order.
