Electric additional pump for the stove of VAZ and other cars: selection and installation

With the help of an additional pump for the VAZ stove, you can solve the problem with the low performance of the cooling system. This can be done on almost any domestic car. The stove functions normally under average operating conditions, but it may fail at extremely low or very high ambient temperatures. If the outside temperature is very high, the engine will begin to overheat. If the temperature is too low, the cabin will be very cold. This happens due to the fact that the heater does not work well and cannot provide normal air temperature in the car.

In what cases should you consider installing an additional pump?

It is recommended to install an additional pump in the cooling system if:

• When the air temperature is above 28-30°C, the engine reaches a critically high temperature (provided that the cooling system is working properly);
• In cold weather, the heater blows cool air at idle speed at normal engine operating temperature.

Most often, the problems described above occur on the VAZ-2109, VAZ-2114, VAZ-2110, rear-wheel drive “classics”, all GAZ Volga models, except for the GAZ-31105. In the latter case, the malfunction may also occur under normal temperature conditions. This is due to the large volume of coolant in the system and an insufficiently powerful pump. It is worth noting that there is no need to install an additional pump if overheating of the power unit or failure of the stove occurs at temperatures normal for central Russia (-25 - 25 ° C). The corrected standard system operates successfully in this thermal mode. Therefore, if it malfunctions, you should look for a malfunction.

Where to begin?

There are some signs of failure of the VAZ pump. In these models, the pump ensures the passage of antifreeze through the cooling jacket, hoses and pipes, as well as through the radiator. During the warm season, even a slight malfunction of the pump can lead to overheating.

It is worth noting that the symptoms of a pump malfunction on the VAZ-2112, 2107, 2109, 2114 and some other models should be determined as soon as possible. The fact is that in these models the pump is driven by a timing belt. If the pump jams for any reason, it will fail. This, in turn, leads to deformation of the valves in the engine. This situation is observed in most cases when such a failure occurs

Therefore, it is important to independently identify signs of pump failure in the cooling system.

Knowing the symptoms of failure of the VAZ-2114, 2112 or earlier models, you can avoid expensive engine repairs or constant overheating.

It is worth noting that the cooling system water pump has a certain service life. Once the expiration date has passed, this system component must be replaced. In cars with a pump driven by a timing belt, this element of the system should be replaced every 60 thousand. km mileage This distance is usually around 48 months (with regular driving).

Which pump to choose

Unlike the standard VAZ and GAZ pump, which has a mechanical belt or chain drive, an electric pump is used as an additional driving force. Most often, motorists use an electric pump, which is standard equipment on the Gazelle car.

The unit has high performance, but the quality of its manufacture leaves much to be desired. Therefore, before installing such a pump, it is recommended to disassemble it, coat all seals with automotive sealant, reassemble it and let it dry for 24 hours.

Note: the above applies to old-style pumps. New GAZ pumps have good build quality. However, over time, they also begin to leak.

An alternative to GAZ products is to install an additional pump manufactured by Bosh. These units have high build quality and a different operating principle. The blade rotates under the action of a magnetic coupling, and not an electric motor, as in the first case.

By using such a scheme, the manufacturer was able to abandon sealing connections and almost completely eliminate the possibility of leakage. The disadvantages of the imported unit include its high cost and relatively low productivity (700 liters versus 1200 liters per hour for the GAZ unit).

Replacement

Having purchased a new coolant pump, you can begin the replacement procedure.

The VAZ 2110 works in conjunction with 8 valve and 16 valve power units. Despite there being a certain difference between them, the pump replacement procedure is identical.

Dismantling works

The instructions below are relevant for dozens with two types of motors.

1. Place the car on a level area above a hole or on an overpass.
2. Lift the hood, remove the negative terminal from the battery, which will turn off the power to the car.
3. Unscrew the cap of the coolant expansion tank. This will relieve excess pressure in the system.
4. Now get down under the car.
5. Place a clean container with a volume of at least 5 liters under the cylinder block.
6. Unscrew the coolant drain plug using a 13mm wrench, which will allow you to drain the coolant. Be careful, unlike oil, you need to drain the coolant when the engine is cool.
7. When all the coolant is out, screw the plug back into place.
8. Using a 10mm wrench, unscrew the three mounting bolts that hold the timing case in place.
9. Remove the casing.
10. Place the crankshaft at TDC of the first cylinder - top dead center. To do this, you need to turn off the gear and turn the special bolt that holds the generator pulley to 19 with a key. Turn until the marks on the camshaft gear align with the mark on the rear timing case.
11. Make sure that the marks on the flywheel and clutch housing match. To do this, you will have to remove the plug on the crankcase. It is made of rubber and is located to the right of the cylinder block.
12. Lock the crankshaft in this position. You can use a simple slotted screwdriver that fits into the teeth of the flywheel.
13. Slightly loosen the tension roller locking nut using a 17mm wrench.
14. Turn the roller using a special wrench in a counterclockwise direction. This way you can loosen the tension level of the timing belt.
15. Now you can quite easily dismantle the tension roller and belt.
16. The next step is to remove the five mounting bolts that hold the lower timing case in place. These include 3 bolts that hold the pump. You will need a socket wrench or a 10mm socket.
17. The casing can then be removed.
18. The VAZ 2110 provides for installation of a pump using three hexagon bolts. Once you unscrew them, you can simply carefully remove the pump by tapping on the body.
19. If that doesn't work, then use a flathead screwdriver to pry up the coolant pump housing, which will allow you to remove the pump.
20. Remove traces of the old gasket that should remain on the surfaces of the seats.

How to install an additional pump

Installation of an additional pump on a VAZ stove can be done in the engine compartment or under the interior panel. The first option is preferable, since in this case the sound of the pump does not enter the interior, and there is also no risk of flooding the interior with antifreeze if it leaks. Depending on the installation location, the unit can be mounted at the mounting location of the standard engine compartment sound insulation or on additional brackets.

The installation of an additional water pump on the VAZ-2110 and other models of the domestic automobile industry is carried out on the heater supply pipe. In this way, it is possible to achieve a more active injection of coolant into the “furnace” radiator and increase heat transfer.

Note: increased pressure in the cooling system can lead to failure of poorly secured pipes or breakdown of the radiator. Therefore, before installing additional equipment, it is recommended to conduct a complete diagnostics of the CO.

Before installing an additional pump, the antifreeze is drained. After this, the pipe at the intended installation site is cut in half using a sharp blade, and the resulting ends are put on the pump outlets. It is important to ensure that the arrow drawn on one of the outlets, indicating the direction of fluid circulation, is directed towards the radiator. The pipes placed on the outlets are secured with clamps. It is better to use Norma brand screw clamps, since products from lesser-known brands often have sharp edges and cut the pipe.

The connection diagram to the on-board electrical network may vary depending on what goals the car owner sets for himself. If the pump is installed for more efficient cooling, it makes sense to connect it in such a way that it runs constantly when the ignition is on. The unit can be connected directly from the battery, but the circuit must be closed using a relay, which is activated after turning the start key.

If you plan to install an additional pump in the heating system to improve the operation of the stove at XX, it is better to connect it through a button. In this case, the power circuit will include a relay, a fuse, a pump button and a battery. Electricity is supplied via a single-wire circuit. The “minus” in this case is the car body. Using this scheme, the car owner gets the opportunity to turn on the pump only when there is a need for it. Note: it is better to install an additional pump using a second power supply connection scheme, since in extreme cold, its prolonged operation can lead to underheating of the motor and related malfunctions.

Electricity

Before connecting an additional pump to the Gazelle stove, the connection diagram should be reviewed for reference. There are several options. One of the simplest ways is to place the button in two positions in the car interior. It's simple here: on/off. For example, if it’s cold you can turn it on, if it’s warm you can turn it off.

This is a simple method, and it has a disadvantage. If you forget to turn off the additional pump, then the next time you start the car to warm up from the alarm key fob, the pump will start and take heat from the cold engine. This will increase the engine warm-up time.

Professionals recommend using a complex but more effective method. There will be a dual control system. This button is intended only to be turned on in winter and turned off with the arrival of spring. This is done to prevent the pump from working unnecessarily.

When the button is turned on, the additional heater pump for the Gazelle stove will turn on/off completely automatically when the engine starts and the car is driving. For this circuit you will need a two-position relay. The pump has a certain power, so the relay needs a current of 3 A.

How to find out what exactly the pump on 2109 has failed

The main problem that prevents the continued use of a water pump is its loss of tightness, which leads to the leakage of working fluid. Slightly less often, problems are caused by bearing wear.

In the first case, the pump remains suitable, therefore the easiest way to protect the power unit from overheating is to regularly restore the volume of liquid in the cooling system. This measure, however, gives only a temporary effect, since the leak will intensify day by day.

Bearing damage is much more serious. At first, this element signals its wear and tear with a fairly loud noise. If you do nothing, the destructive process will accelerate, and, most likely, the matter will end in the complete destruction of the part. The backlash formed in it is manifested by the following signs:

• loud grinding noise;
• pump jamming.

Ultimately, the likelihood of the drive belt breaking or even damaging the engine valves increases.

The pump installed on 2109 cannot be repaired, and therefore, if its improper operation is detected, the unit is dismantled and a new one is installed in its place.

The procedure, fortunately, is not particularly complicated, which means that replacement with a VAZ can be done without going to a car repair shop. The pump is located in an easily accessible place and no overall engine components (for example, a carburetor) will have to be touched.

We recommend: Camshaft sensor Kalina 8 valves

Cavitation, bearing damage

When considering the symptoms of a motor pump failure, you should pay attention to such a negative phenomenon as cavitation. This is the process by which air bubbles form in antifreeze.

They damage the internal surfaces and individual parts of the pump. As a result, scratches remain on them. Then they rust.

Air bubbles appear in the pump inlet. When the pressure in the system increases, they are destroyed. This process causes significant system damage and can cause engine failure. Therefore, it is better not to save money and buy a new pump. It will be much more reliable than a refurbished pump.

It is very important to install it correctly in its original place

Particular attention is paid to seals and proper tightening of fasteners. In some cases, a special sealant is used for joints

Eliminates leakage. However, it is not always possible to use the presented material. This will prevent you from later loosening the engine mounts to secure the timing belt on some car models.

If you know the signs of a bad pump, you can replace it on time. First you need to remove the cover from the timing belt. If necessary, the tensioner will need to be loosened and removed. Then reduce the mounting force on the generator. Its belts and timing belt have been removed. The hose from the pump can be disconnected. Then the antifreeze is drained. After this, you can remove the protective cover and pump.

After installing the new pump in place, align the alignment marks. This is necessary because the crankshaft can move relative to the camshaft.

Expected results

After all the necessary elements have been installed and connected, road tests should be carried out, during which the pump must run continuously for at least an hour. During this, it is necessary to carefully inspect all its connections to the cooling system to eliminate leaks.

After the inspection, you should check the car while driving. It may happen that a unit functioning properly at idle speed will fail when the pressure in the pipes increases.

If everything was done correctly, the heater begins to supply warmer air, and the engine is effectively cooled even under heavy loads.

If standard heating is not enough, the problem must be solved somehow. You can try installing a second radiator, but a more obvious solution would be to install an electric pump. It is additional and pumps liquid along a small circuit. An additional pump can be installed on the VAZ-2114 stove in 5 minutes. The problem is that the coolant needs to be drained. Otherwise, there will be no difficulties: all parts are standard and are produced by AvtoVAZ itself.

The result of our efforts is what is shown in the video. Let's see.

Basic moments

It is necessary to try and install the pump correctly on the vase, since excess pressure in the stove radiator can cause cracks and ruptures in the pipes.

In some cases, it is necessary to replace the thermostat and install a new one in place of the old one, which has a higher opening temperature. The need for such manipulations can be explained by the fact that with a high antifreeze circulation rate, the engine cools strongly, but heats up very slowly. This causes its accelerated wear. The thermostat opening temperature set at the factory is 80-85 degrees. But some experts recommend setting the temperature to 90-95 degrees.

Cooling system and its features

From thermostat 29 to tap 21 there is a “supply hose”. We are not interested in him! The pump is inserted into hose 19. It is connected to the pump supply pipe (part 20).

Everything here is trivial

If we look from under the bottom, we will see two hoses near the partition. We need the one that is fixed closer to the right wheel. And now, instead of hose 19, an assembly is installed: the same hose “21083-8101010-01”, an electric pump, hose “2101-8101204” (to pipe 20). That's all, actually.

Each hose is attached to the nozzles with two clamps. The article number of one clamp is “2108-1300080-10”.

Purchase parts in advance:

• BOSCH pump 0 392 020 034 or pump 32.3780-01 for Gazelle with 18 mm pipes (important);
• Electrical parts;
• All hoses and clamps;
• The BOSCH pump requires VAZ fasteners: a intake pipe clamp, as well as a bracket for this clamp (all from LADA-2101).

The pump from the Gazelle will have to be modified: the body is disassembled, degreased, the rubber gasket is lubricated with sealant...

GAZ pump after modification

When assembling, use screws with nuts instead of standard self-tapping screws (see photo).

By installing an additional pump on the VAZ-2114, you don’t even have to connect it. Everything will work as before. The main thing is that the pump does not leak, and we have already indicated the solution.

Need to know

You can add a heater to the car’s heating system yourself; to do this, you need to buy an additional heating element. Or you can try and make it yourself; for these purposes you will need a second radiator and a housing for a new heating element, which can also be made at home.

Where to put

1. In the distance between the front seats where the tunnel is located.
2. Under the front seat.

Suitable Models

• Technomaster-8110.0500.10 and 8110.0700.10 (Tolyatti). Its price varies within 3000 rubles.
• Helios, Xeros and Zenith (Eberspächer) - are more expensive, from 3500 rubles.

Approximate procedure for installing an additional pump

If all the necessary parts have been purchased, do the following:

1. A “unit” consisting of three parts is assembled.

The short hose is the “outlet”.

Below is an example with a BOSCH pump.

Antifreeze drainage unit

External outlet hose

BOSCH pump mounting method

Be aware that the plug from the knock sensor will fit into the pump connector (you need to buy it). The connection diagram is discussed below.

Example with a GAZ pump

Clarifications for the domestic pump:

1. Do the “assembly” as in step 1 (see above);
2. The “assembly” is assembled;
3. The pump mounting location is the upper corner of the manual transmission housing (see photo). Without the details of an iron constructor about here .

GAZ pump mounting method

Variant of the scheme for the VAZ-2114

We connect the motor through a fuse and a relay rated at 10 Amps. The relay will be turned on by a button attached to the device.

Scheme (simple version)

The “+” voltage was taken directly from the battery, but this can be done - a sealed holder “hangs” on the wire, where the fuse (5A) is located. Installing a button looks simple:

1. Remove all the handles;
2. Move the plastic panel towards you;
3. We install a new button and connect the wires.

As a result, you can see what is shown in the photo.

Circulation button

What can be improved

• A diode is connected in parallel with the relay winding in the “back to front” direction, thereby extending the service life of the button;
• Connecting to the battery directly is bad. It’s better to find another point with a “plus”;

What we got

Negative aspects of installing an additional stove in the cabin

1. An increase in the heat capacity of the cooling system entails slow heating of the coolant.
2. The characteristic noise of the stove in the cabin will be added, since now there will be two of them working.
3. The air flow from the stove will raise dust from the interior.
4. In the warm season, hot hoses under the floor covering will additionally heat the interior of the car, but there is a way out of this situation - install a tap in the engine compartment when making changes to the cooling system.
5. If you do not install another heater regulator and heat dissipation to the side, then there will be no uniform heating, but only one part of the interior will become very hot.

Installing a second heater radiator on a VAZ-2109 will be advisable only in areas with very low temperatures in winter, where the basic heater, despite its proper operation, does not cope with the task and the car does not warm up properly.

Summer is the best time to think about winter

Life goes on as usual. And if it’s still warm outside now, winter will still come sooner or later. Many pages have been written about how to still make the Gazelle warm, but it seems that there is simply no better solution than installing an additional pump.

So, this additional pump is necessary in order to improve the coolant circulation processes in the heating and cooling systems. As for the principles of working with this system, here the additional pump for the Gazelle stove is mounted on a section of the hose to the radiator after the thermostat. This can significantly speed up the speed at which the hot coolant mixture passes through the heater.

What is needed to install a new pump on a car?

Alas, many cars, regardless of the manufacturer, do not withstand any criticism in the harsh Russian conditions in matters of interior heat supply. Simply put, the performance of the stove does not live up to the expectations placed on it, and in the car, even with a big minus outside, it is simply cold. But it turns out that everything can be fixed, and with our own hands. The main thing is to have a head on your shoulders and instructions for use.

Modernizing a car's heating system involves installing an additional electric pump. Let's look at the example of the tenth VAZ model, since most often the owners of these cars complain about the lack of sufficient heat in their cars, especially when the engine is idling. To carry out the operation you need:

1. Electric pump from Gazelle. It is this model that is better suited to this role of an additional heat pump into the cabin. It is a simple centrifugal pump in which the fluid flow is rejected from the center to the periphery by means of blades.

We recommend: Transportation of construction equipment

2. Relay. It is best to take the starter or ignition relay, where the contacts are best open.

3. Small pieces of aluminum and reinforced hose.

4. Coolant in a volume of at least two liters.

5. Clamps, six pieces are enough.

Pump installation process

Before starting work, cool the engine naturally. Then drain the coolant into a clean container. We will need it later, so we have to worry about its cleanliness.

After this procedure, take a new pump and, on the side where the impeller is located, unscrew the four screws. The gasket made of rubber material, which is found in this place, is lubricated with conventional sealant. Next, we reassemble the pump, but instead of the removed screws, we install elongated thin bolts under the nuts. Only this approach ensures the best sealing of the connection.

The next step is to determine where to install the additional electric pump. There are several possibilities for this:

— on the washer reservoir mounting stud;

— on a pin near the battery;

— on the mounts of the standard Shumka, located on the engine shield.

Usually, preference is given to the standard approach, which is described in the instructions included with the electric pump, that is, the second option. Therefore, the pump must be positioned in such a way that its horizontal pipe faces the block, for which the iron fastening clamp must be loosened.

The next step, after installing the pump in the selected position, is installing the hoses. To do this, remove them from the stove and from the tube coming out from under the manifold. Next, take a reinforced hose of sufficient length and try it on in place. The main thing is that it reaches from the collector brass tube to the pump tube without kinks or stress.

Installation of the unit - algorithm in detail

The installation of an additional circulation pump in a standard heating system does not depend in any way on the type and material of the latter. In any case, installation will have to be done using the bypass method. If the house is equipped with a metal pipeline, then you can purchase a ready-made structure that allows you to bypass the main highway. Before installation, you will need to completely drain the liquid and clean the pipes. To do this, the pipeline must be flushed several times. After this, a piece of pipe bent in the shape of the letter “P” is installed on the side of the main pipe.

Subtleties of installing an additional pump in the heating system

Fix the pump in the middle of the pipe. Place ball valves on both sides of the device. What are they needed for? First of all, the water circulation will return to normal if you turn off one of the taps. Secondly, in case of repair of the unit, you will have to drain the water; if there are taps, this will not be necessary. During installation, pay attention to the direction in which the liquid moves. It is marked on the pump body with a special arrow. Upon completion of installation, the system is filled with water and the operation is checked. If any problems are detected, they should be eliminated at this stage of the operation.

Next, using the central screw, we expel the stagnant air from the pipes. If everything is done correctly, water will begin to flow from a separate hole in the pipeline. To install a unit with manual control, the air must be removed from the pipes before installation begins. To do this, the device is turned on for a few minutes, after which the equipment valves open. This procedure should be repeated several times. As soon as the pipeline is filled with a sufficient amount of liquid, the pump itself will start. In this case, the presence of air in the pipes is strictly unacceptable.

Installing an additional pump on a VAZ 2109

In this article we will learn how to install an additional pump on a car like a real auto electrician. The VAZ 2109 is a car that allows you to constantly modernize and improve something, however, like all models of this family. Let us present to the reader two algorithms on how to mount a pump from Gazelle and from Bosh.

Installing a Gazelle pump

As mentioned above, this is the most common option for installing an additional pump. Tools and materials:

• The Gazelle pump is standard. Costs about 1000 Russian rubles.
• Relay with normally open contacts. Standard relays from the starter or ignition will do, where you just need to bridge the necessary contacts.
• Some reinforced hose.
• 2 liters of coolant (regular antifreeze).
• Medium-sized clamps in the amount of 5 pieces.

• We wait until the coolant in the system cools down. The antifreeze is drained from the tank into some clean container if its reuse is intended. If you intend to use new antifreeze, then you can drain it for recycling.
• On top of the pump we see 4 screws. They will need to be unscrewed to get to the rubber seal of the impeller. We lubricate this gasket with a sealing compound.
• We assemble the pump, but instead of standard self-tapping screws we install long thin bolts, on the advice of an auto electrician. The VAZ 2109, by the way, is a car in which the Gazelle pump is quite successfully installed.

Advice. Some motorists who are installing an electric pump for the first time are wondering: where is it better to install the pump, in the gap in the heater supply pipe or in the outlet pipe? In fact, there is no difference in this, as long as the pump is installed downstream of the coolant flow.

Auto electrics for VAZ 2109 – electric pump

Note. You can mount the additional pump on the VAZ 2109 directly to the stud of the washer reservoir or to the stud near the battery. In addition, some craftsmen advise installing it on the factory Shumka mount, which, as you know, is located on the engine shield. It is most rational to place it near the battery, which is what we will do.

• Unclench the iron clamp.
• We install the pump with a horizontal pipe towards the block.

Now you need to think about how to establish a connection. It is most practical to transfer the connection to the recirculation button. If not, then you can put it on the SAUO unit or on heated mirrors.

• Two wires are disconnected from the recirculation valve: with a white-blue stripe and a yellow-blue stripe.

Note. Let us remind you that the recirculation valve is located on the engine compartment panel, and two thin hoses go to it.

• We connect the blue-white wire to one terminal of the relay.
• Yellow-blue to the second relay terminal.
• We connect the third terminal of the relay to the wire of the electric pump.

Now it's time to check how the pump works. When you press the button, the pump should begin to hum and blow air. If this does not happen, then something was done wrong. We continue with the installation:

• Disconnect hose 1, which carries coolant to the heater from the outlet pipe.
• We connect it to the horizontal pipe of the pump (the length is enough, if anything).
• Now you need to connect hose 2 to the vertical pipe of the pump, which itself consists of 2 S-shaped pipes (it is located between the tap and the heater radiator). As a last resort, instead of this hose, you can use another one of a suitable size and type.
• The second end of this hose must be pulled to the block head, from where hose 1 was removed.
• Tighten the clamps.
• Be sure to tighten the drain plug in the block.

• Fill coolant to the maximum mark.
• We turn over the engine.
• Visually inspect the pumps for leaks.
• Then we turn on the ignition again and check for leaks, which we fix if found.
• We tighten the clamps.
• Let the engine run for about 30 minutes.
• Refill coolant to the required level.

Checking the new pump

It is advisable to check in air when the temperature is about -10 degrees Celsius:

• The engine temperature should be +85.
• We turn off the engine.
• We turn on the heater at first speed and watch how semi-warm air blows.
• We turn on the additional pump and immediately see the difference: hot air blows! Hot air flows until the engine temperature cools down to +45 degrees.
• We start the engine again, heat it to the desired temperature and check everything again.
• If everything repeats, then the pump is functioning normally.

Bosh pump installation

Auto electrics for VAZ 2109 – Bosh electric pump

• A pump from Bosh, which costs about 1,300 rubles.
• Relay with chip.
• Two wires of 5 meters of different colors.
• 20 different terminals.
• A button with an LED, usually used on foreign cars.
• Special connector for pump.

• First of all, we lay the electrical wires.
• It is advisable to install the relay behind the car radio.
• From the relay we lay a 12V wire to the pump.
• The other wire goes to the button with the LED.
• Don't forget to connect ground to the button.
• The plus appears from the radio when the ignition is turned on.
• As a result, when the car is running, after pressing the button, the LED lights up and the additional pump begins to function.
• Now we install the pump itself.

Note. A common problem when installing an aftermarket pump can be threading the factory hose onto the pump. Let us note right away that it is easier to go and buy a new one than to try to tighten the standard one.

• We thread a new hose for the stove 18 mm.
• We place the pump and cover it with double-sided tape, and then secure it well with a clamp.
• We lead the +12V wire into the engine compartment to the ECU.
• Connect and you're done.

The costs of such an installation are minimal. If it costs about 2,000 rubles, that’s still a lot. Refinement of the standard system will only give positive results. The instructions given above will tell you how to do everything with minimal loss of time and money. Videos and photos will help you gain practical understanding in the process, so we don’t ignore them. The cost of installing an additional electric pump will not affect the family budget in any way if you do everything yourself.

Foreign pump

Imported devices have some advantages over domestic ones. One of them is weight. For example, the device from Bosch is lightweight, so it can be freely attached directly to the hoses. The difference in design is that the “Gazelle” pump is stuffing box. At high speeds, it creates increased pressure in the system and leaks. The imported device, on the contrary, has a sealless design, and the electric motor is in no way connected to the pump.

As for performance, it is preferable to purchase an imported additional pump for the Gazelle stove. Its description shows that it is superior in quality and power to its domestic counterpart. Its parameters are the same as in the domestic version. The device is powered by 12 V, and the pipe size is 18 mm.

As for the reviews about the operation of this additional pump, those who upgraded the heating in the Gazelle in this way were satisfied. In the harsh Russian winters, the cabin of the car became warm and cozy.

Installing an additional electric pump for the Volga heating system is often recommended as a means of increasing the efficiency of coolant circulation through the heater radiator and, as a result, improving the performance of the heater. It should be noted that this upgrade should be carried out when all measures have already been taken and weaknesses have been eliminated, namely:

• hoses to the heater radiator were replaced from diameter 16 to diameter 18;
• the coolant intake fitting from the cylinder head (the so-called “tank”) was replaced with a gazelle one, with a diameter of 18 mm;
• The stove valve has been replaced with a suitable one with a larger cross-section, for example, a water ball;
• heater radiator – copper three-row;
• a pump with an 18 mm fitting is installed;
• a bushing is installed in a small circle to throttle the coolant flow and provide greater flow to the stove;
• All cracks and irregularities have been eliminated in the design and water ducts of the stove.
• A properly working thermostat is installed (I have a thermostat from a Niva-Chevrolet).

After all the previous points have been completed, as a last resort you can install an additional electric pump from the Gazelle heater. The procedure is simple, however, for beginners some points may not be entirely obvious. Now I will tell you how to independently install an additional electric pump on the stove on the Volga.

You will need the following parts:

1. Actually, the electric pump is from a Gazelle car;
2. Corner;
3. Two short pieces of 18 mm hose;
4. Four clamps;
5. Two rubber bushings from silent blocks of the front suspension;
6. Two M5 screws or studs, I prefer studs because... it is easier to mount the pump on them, as well as nuts and washers of large diameter;
7. 30A relay, terminals and wires.

First, prepare the place and remove the washer reservoir:

What does it give

An additional VAZ 2114 pump provides warmth and comfort in your favorite car. You can save a lot on warming up your car if you like comfort. In practice, the car will noticeably heat up within 5 minutes after turning on the heating system, which cannot be achieved using a standard heating system.

Speaking of pros and cons: firstly, the domestic pump has only a plus, and the minus is the unit housing itself, and secondly, it is better not to leave a plus on the battery, despite the fuse, it is better to look for another point to connect it.

Let's sum it up

Taking into account the above information, it becomes clear that an electric pump for a stove is a fairly simple and convenient solution that allows you to increase comfort and safety when operating a car.

In practice, after installing such a pump, it is possible to warm up the interior faster, which is important when making short trips over short distances or while driving fast on the highway in winter. The glass warms up faster and sweats less during a trip, it is easier and faster to remove snow and ice from them, etc.

As for the choice of the pump itself and its installation, the additional GAZelle pump is in demand, primarily due to its low cost. At the same time, we are not talking about quality.

Finally, we note that an additional pump in a VAZ 2109, 2114 or on a budget foreign car can significantly increase the level of comfort, save on warming up the car, etc. If the installation is done correctly and the pump is working properly, the interior will heat up faster compared to the standard heating system.

The only thing is that you should periodically check the tightness of the cooling system, since even standard elements can leak. If we are talking about additional non-standard elements, in this case the connection points require separate control.

Necessary materials

Before you begin installing an additional pump on a vase, you must purchase all the necessary materials. The list of required materials includes:

• electric pump from a Gazelle car. This part will act as a pump;
• a relay with slightly open contacts (an ideal option would be a relay from a VAZ 2108);
• reinforced hose, at least 1 meter long;
• hose clamps (at least 5 pieces);

In order to prepare a VAZ car for installation, it is necessary to drain the antifreeze from the radiator and cylinder block.

Pump installation

To install an additional pump on a VAZ 2110, you need to crimp the pipe coming out of the stove. This will help prevent antifreeze from leaking. However, experts believe that it is best to completely drain the antifreeze from the system. When the work space is cleared, you need to take the pipe and cut out a part from it that will correspond in length to the length of the pump. At the same time, the length of the fittings themselves should not be taken into account, since they will fit into the pipes.

If, for certain reasons, the outer diameter of the fittings does not coincide with the inner diameter of the nozzles, you will have to use adapters or select a pump of the appropriate diameter for installation. The second option is often more practical, since each adapter represents a potential leak point.

In order to increase the level of efficiency of the device, it is necessary to remove four screws from the part and remove the upper housing. The internal gasket of the pump must be carefully treated with sealant and the entire part must be reassembled. But re-fastening the housing is best done using long bolts and nuts. This way you can provide the future pump with greater tightness.

Installation location

The connection diagram consists of several stages:

• The white and white-yellow wires must be disconnected from the recirculation valve. The first wire is connected to the relay contact number 85, and the second is number 30. Contacts 30 and 86 are connected using a jumper;
• pin 87 is connected to the pump wire. To check the operation of the pump, you need to connect the ground. If the ground rotates, then all connections are made correctly.

Connecting the pump

When connecting the pump, be sure to set the switch. If the device operates in forced mode without the ability to turn off, in the summer it will be unbearably hot inside the car. An O-ring must be installed around the perimeter of the switch, which will hide the place of its contact with the body. The negative wire will be connected directly to the pump, past the switch, and the positive wire will go through it. Thanks to this device, an additional pump for the VAZ 2110 can be connected only as needed.

It is worth noting that installing an additional pump is not always advisable. This is due to the fact that often the reasons for inadequate heating of the interior are malfunctions in the stove or a poor-quality thermostat. It is for this reason that before deciding to install a pump, it is necessary to carefully check the entire antifreeze circulation system.
