How to change the radiator of a VAZ-2110 stove with your own hands

The most common problem that significantly affects the high-quality heating of the interior of a domestic car is. Under the action of the coolant, corrosion and destruction of the internal surfaces of the part occur, which as a result provokes a leakage of the radiator.

It is not rational to use a faulty radiator, since a coolant leak will negatively affect the operation of the vehicle's power unit, entail its frequent overheating, which can lead to more serious damage to the car. The problem can be solved by replacing or repairing the heat exchanger with a new product. This article will discuss how to change the radiator of the stove on the VAZ-2110 with your own hands.

Causes of the stove radiator leakage and troubleshooting options

There can be several reasons for the leakage of the heat exchanger. The first is a poor-quality connection of pipes and hoses. To eliminate the problem, new clamps are used and a tight connection of the butt joints is made. The second is a radiator punctured or worn out through metal corrosion. Some car owners try to fix the leakage by soldering the product, however, such repairs do not always pay off. Moreover, only more expensive copper products can be soldered. The leaks corrode very soon and the problem reoccurs.

The correct solution to the problem would be. And also the reason for the poor-quality operation of the radiator may be its clogging or the formation of scale on the inner walls of the product. In this case, you can flush it with special means yourself or ask for help from car service specialists. It is important to note that the services of employees of service centers are very expensive, therefore a more practical option is to troubleshoot the malfunction yourself.

It is impossible to determine the source of the coolant leak without disassembling the shield in the engine compartment, therefore it is better to immediately purchase a new heat exchanger and replace the worn-out part.

Choosing a stove radiator for the VAZ-2110

Dozens have two types of heating systems, depending on the model year of the vehicle. The machines, which came off the assembly line before the fall of 2003, are equipped with old-style stoves. Subsequent models are equipped with new type heaters. When buying a stove radiator, it is important to take this fact into account, since the parts differ in design characteristics.

For VAZ-2110 vehicles, there are two types of radiators on sale. The most common are aluminum products, which are not too expensive and light in weight. However, aluminum has a low level of heat transfer and is highly corroded, therefore the service life of such products is not very long.

Better quality are copper radiators, which are characterized by resistance to corrosion and a long service life. Copper products have a high level of heat transfer, which significantly affects the quality of heating the vehicle interior. The only drawback of the products is the high price. Which radiator to buy depends on your financial capabilities and wishes.

Additionally, to repair the radiator, you will need to purchase clamps, preferably with a margin. And also when repairing the heating system, it is advisable to replace the pipes, since they are often exposed to temperature extremes. For repairs, you will also need a Phillips screwdriver and technical tweezers for easy dismantling of parts.

After preparing the required tools and purchasing new parts, you can proceed directly to replacing the heat exchanger.

Before carrying out operations for replacing or repairing the radiator, it is necessary to drain the coolant from the heating system. All work will be carried out in the engine compartment. To get to the heat exchanger of the stove, there is no need to dismantle the panels in the vehicle interior.

There are two ways to drain antifreeze from the system. It is necessary to prepare a clean container for the coolant. If the liquid is clean, then it can be poured back into the system after work.

The first method involves draining antifreeze from the engine block. To this end, it is necessary to remove the tank cap to reduce the pressure in the system. Then the drain plug behind the ignition unit is unscrewed and the coolant is drained into the prepared container. Approximately four liters of antifreeze should flow out.

The second way is to drain the coolant through the expansion tank. For this purpose, it is necessary to disconnect the hose near the stove and drain the antifreeze from it, which should flow out about a liter.

After that, the branch pipe is removed, and the fastening clamps are loosened.

Further actions will be determined by the type of stove that is on your vehicle. Let us consider in detail how to remove and change the heat exchanger of the old and new types in stages.

Replacing the old-style heater radiator

To replace the old-style VAZ-2110 stove radiator, the windshield lining with a rubber seal is initially dismantled. To remove it, first unscrew the fastening bolt of the lining under the brake cylinder and the four bolts of its upper fixation on the passenger side. Then the clamps are dismantled, with the help of which the pipes and hoses are attached.

Then it is imperative to disconnect the fan electrical wires from the vehicle body. After carrying out such manipulations, access to two fasteners from the driver's side of the windshield lining will open. They must be dismantled, after which you can move the frill slightly forward. You do not need to remove it completely. Then the remaining nuts and bolts that hold the windshield cover are unscrewed. After that, the plastic strip between the windshield and the engine compartment can be completely removed.

Further, it is important to disconnect the terminal of the sensor, which shows the coolant level and the hose for removing the vapor is dismantled from the expansion tank. Subsequently, it is necessary to remove one by one the windshield washer hose, wipers, fasteners on the heater housing, the front block of the fan housing, the fan, the cabin air cleaner, the rest of the fan housing and all the hoses of the heating system. After that, you can easily pull out the radiator housing.

The next stage of work is the replacement of the failed heat exchanger with a new part and the installation of all dismantled elements in their regular places. When assembling, concentrate on installing the plastic fan casing. It is important that the pedal is in the appropriate slot, otherwise the vehicle heater will not function.

It is also necessary, perhaps it also needs to be replaced. If there are visible defects on the pipes and hoses, they must be replaced. Make sure that all connecting clamps and fasteners ensure a snug fit of the parts, otherwise you will not wait for heat in the vehicle interior. This completes the replacement of the stove radiator.

Replacing the radiator of the stove of a new sample

Replacing the radiator of the VAZ-2110 stove of a new sample has features associated with the method of connecting the heat exchanger to the vehicle body. In order to dismantle the part, you will need to unscrew the central bolt in the lower segment of the windshield. Next, two nuts are unscrewed above the intake manifold and one near the cabin filter on the left. The next step is to remove the air filter, which is attached to the stove with four self-tapping screws.

The modified heater is formed of two parts, which are connected by three self-tapping screws. It is necessary to unscrew the large self-tapping screw and two additional bolts that connect the constituent parts of the stove. After that, the right component of the stove is moved to the right to the maximum possible position. Holding the left segment with your hand, you need to stretch the right side, turning it towards you and lifting it up. Then you can remove the left side of the stove. Through the passage of the soundproofing shield, a hose for the removal of steam is led out.

The right segment of the stove is divided into two more components. To separate the right-hand side, you need to dismantle the mounting brackets. The right side of the stove can then be opened without significant effort. The overview will open the heater flaps, which are also desirable to be replaced. The best option for this would be aluminum gate valves, which are wear-resistant and are less subject to deformation.

The last stage of work is the installation of a new part and assembly of all in the reverse order. Make sure that all connections are well tightened, as this will significantly affect the functionality of the interior heating system.

Let's sum up

Replacing the vehicle heater radiator does not differ in significant difficulties, however, it requires the utmost care and stage-by-stage work from the contractor. will help to save money on the services of specialists and to understand in more detail the system of functioning of the car heater. Buy only high-quality certified parts so that in winter the car will delight you with comfort and coziness.
