Installation of an additional stove in the interior of a VAZ-2114 1

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.

What is a pump?

A pump is a liquid pump that creates excess pressure in the cooling system. Using this pressure, the liquid circulates through all pipes of the system, evenly taking heat from all heated elements. On most vehicles, pumps are mechanically driven by timing belts or a generator.

As for the additional pumps, their design is approximately the same as the standard ones, except that they are driven by an electric motor. This is much better, since even at low crankshaft speeds (i.e., at idle), effective cooling can be achieved. All liquid will circulate through the channels at maximum speed, which will improve the operation of the entire system.

Please note that to this speed you still need to add the pressure that is created by the standard pump - no one removes it during modernization. After all, the task is not to replace the pump with another, but to improve performance.

How to properly connect an additional pump

Beginners in the VAZ-2115 repair business often have a question: how to properly seal the ground wire of the winding when installing the pump?
Only to ground, and connect the power wire to the wire coming from the pump. Pass the positive wire coming from the relay through a fuse connected to the battery positive wire. The control wire from the relay should be routed to the start button inside the car, taking into account the battery positive. The key can be placed in any convenient place for the driver, at his request.

What else needs to be done so that the installation and connection of an additional pump in the VAZ-2115 is considered complete? Check the operation of the pump. The verification instructions consist of the following sequential manipulations:

1. Fill the VAZ-2115 with antifreeze or antifreeze.
2. See if the antifreeze level is sufficient; if not, add more. If there is not enough fluid, the cooling system will fail, which means the engine will heat up too much. This is fraught with overheating of the engine followed by combustion. Such a breakdown is eliminated by replacing the entire part, which is not cheap today.
3. When the antifreeze is in place, start the car and wait until the engine installation warms up.
4. Click on the mounted button; this action will allow you to start the additional pump built into the VAZ-2115.

When should you consider installing a second pump?

An additional pump for the VAZ-2114 stove can significantly improve comfort in the car in winter. It is often necessary to install an additional pump in the cooling system in the following cases:

• If the air temperature is more than 30 degrees, and the engine in such conditions overheats to critically high values. But only if the entire cooling system is in good condition. Therefore, before installing an additional pump, you need to make sure that the cooling system is working correctly.
• In the event that in cold weather the heater blows cold at idle, and the engine temperature, according to the dashboard indicator, is in the operating range.

But such problems do not always arise and not on all cars. The main criterion is the complete serviceability of all cooling elements. If the thermostat is faulty, then no additional pump will help in this case. First, you need to completely overhaul the system, install new pipes and clamps, and treat the joints with sealant. And only after that carry out the modernization.

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.

What machines might have problems?

Very often such problems can be found in cars of the 9th family, as well as the 14th, “tens”, as well as “Gazelles” and “Volgas”. The only exception is the GAZ-31105 model. On this car, the listed malfunctions can manifest themselves even at normal temperatures. The problem is that there is a lot of liquid in the system, and the pump power is simply not enough.

Please note that there is no need to install an additional pump on the Gazelle stove if the engine is overheated or the stove fails to operate at normal temperatures. If the temperature ranges from -25 to 25 degrees, then a standard working cooling system will function normally in this case. If a failure occurs, then you need to look for a breakdown, which, as a rule, lies in the standard pump or thermostat. Sometimes radiators become clogged.

Pump selection

Standard pumps are driven by a timing belt, generator, and so on. But additional pumps for the 2114 stove are usually made on the basis of an electric pump. Motorists often use electric pumps that are installed on Gazelle cars. This unit has very high performance, but the build quality is not always very good. Therefore, before installing such a pump, you need to completely disassemble it, lubricate all the seals with sealant, then reassemble it and wait at least a day for all connections to dry.

Everything that was said above should only apply to old-style pumps. As for the new pumps on Gazelles, they are of fairly good quality. But after some time they can still leak.

A good alternative to the Gazelle pump is a similar one manufactured by Bosch. These units are of very high quality and also have slightly different functioning. The impeller rotates under the action of a magnetic coupling. The pumps use a DC electric motor. Since this scheme is used, it was possible to get rid of sealing connections. In this case, the possibility of leakage is completely eliminated.

But there are also disadvantages. First of all, this is a high price, as well as low performance. Let's compare the additional pump for the Bosch stove with the Gazelle unit. If the Gazelle pump has a capacity of about 1200 liters per 1 hour of operation, then the Bosch pump has only 700 liters.

How to install a pump

It is best to install an additional pump for the stove either in the engine compartment or under the dashboard. It is best, of course, to install it under the hood, since excess sound during operation will not penetrate into the cabin. In addition, you completely eliminate the risk of antifreeze getting inside the cabin if a leak suddenly occurs. The unit can be mounted using additional brackets. For all VAZ and GAZ cars, an additional pump is installed in the supply pipe of the stove. Consequently, you will be able to achieve the injection of coolant into the radiator, which significantly increases heat transfer.

Please note that in this case, during operation, the pressure in the cooling system will increase significantly. This can lead to loose pipes breaking off or the radiator breaking through. Therefore, before installing additional equipment, it is necessary to fully diagnose the cooling system, and be sure to eliminate all faults.

Working with a resistor

In order to be able to regulate the rate of heat entering the cabin, you can install an additional resistor for the VAZ-2107 heater. Typically the resistor has two spirals with a resistance of 0.23 and 0.82 Ohms.

The new resistor is installed under the gas pedal so that access to it is free. When the stove is turned on at first speed, the current will flow through 2 spirals. At the second speed, the current will flow through a spiral with a resistance of 0.23 Ohms. Current flows past the resistor when the third speed is turned on.

The resistor is located to the right of the accelerator pedal and is mounted on the rear of the air conditioning control unit.

Thus, the car will warm up much faster and better. An additional advantage is the reduction of glass fogging and air circulation in the cabin. In general, the heating of the air in the car will be more uniform.

Preparing to install the pump

Before installing an additional pump on the VAZ-2110 stove, it is necessary to completely drain the antifreeze from the system. After this, you need to use a blade to cut the pipe on which the pump is supposed to be installed. A pump is installed in the gap. Make sure that the arrow, which is drawn on one of the pump outputs, is looking at the heater radiator. It indicates the direction of fluid movement.

The pipes that are put on the outlets must be secured with reliable clamps. It is recommended to use Norma screw-type clamps, as they are more reliable than all others. On sale you can find products from lesser-known manufacturers, which have very sharp edges. When tightening, they simply cut the pipe, which causes a leak.

Another pump

An additional pump for the VAZ-2107 stove can also improve heating in the car. The pump is usually installed next to the battery and hoses. When installing, you need to remove one hose that comes directly from the unit. Connect this hose to the additional pump. The hose should go from the block to the bow of the pump, and the outlet hose should go to the stove.

Power for the additional pump is taken from the heated rear window button. There is only one positive wire coming from the additional pump motor, and the housing itself is ground.

Powering the pump is simple:

1. The very first plug with wires is removed, and the second gray wire, responsible for heating the rear window, will be our basis.
2. We wind the power from the pump to it and bring it under the hood.
3. To keep the wire more secure, you can solder it.
4. After installing the plug back, you can say that the pump is ready for use.

Connection diagrams

Please note that almost any electrical connection scheme can be used. It depends on what goals you set for yourself. If you are installing a pump to cool the engine more, it is recommended to connect it so that it always functions when the ignition is turned on. The pump can be powered directly from the battery. But you need to make sure that the circuit is closed only with the help of an electromagnetic relay, which will be activated only after turning the key in the ignition switch.

In the event that an additional pump is installed only to improve the operation of the stove in idle mode, it is best to connect the power through a button. In this case, it is necessary to include elements such as a fuse, relay, power button, and battery in the power circuit. Electricity can be supplied using a single-wire circuit. The “minus” is the car body. If you use such a scheme, then you will be able to turn on the pump when the need arises.

What to expect in the end?

When all the elements are installed and connected according to the diagram, it is necessary to perform operational tests. It is imperative to fill the system with antifreeze - starting the pump without it is strictly prohibited, as this will lead to its failure. The minimum operating time of the pump during testing is 1 hour. At the same time, be sure to inspect all joints and connections to identify leaks. If they are not detected, it is necessary to check the operation of the system on the fly. After all, it may be that the pump operates stably in idle mode, but when the pressure increases, it simply fails. If all work is done correctly, warmer air will enter the cabin. In addition, even under increased load, the motor will be cooled efficiently.

Hi all. Today I’ll tell you about a useful modification to the stove, which will improve the efficiency of the stove, and at the same time the interior climate. You will learn how to install an additional pump on a VAZ 2114 at home.

Owners of “fourteenth and fifteenth” are well aware of how there is not enough warmth in cold times, and we are not talking about global seasonal cooling, but about the climate inside the beloved swallow. While driving, the stove’s performance is quite sufficient, but as soon as you stop somewhere at a traffic light or in a traffic jam, the stove immediately begins to heat poorly, a lukewarm stream of air comes out of the air ducts, which makes it difficult to warm up. It was experimentally determined that the pump does not have enough power or speed to disperse hot antifreeze.

In fact, not many people know that the “jamb” with the stove and pump, which is observed in all “our” cars, can be eliminated quite easily, the main thing is to know the sequence of actions. As an option, some install an additional radiator, but a more effective option is to install an additional electric pump, which increases the performance of the stove and accelerates heat transfer.

For our “experiments”, it was decided to use an additional pump from the Gazelle; it was decided to install it on the “return” of the stove. In addition, we needed:

1. A button (in my case “recirculation”) plus a connector;
2. Four-pin relay, plus a connector for it;
3. Several pipes plus clamps for them;
4. Wiring;
5. Fuse socket;
6. Sealant;
7. A bracket in the form of a metal corner plus a couple of bolts;
8. Well, as I already said, the pump itself, in my case from the Gazelle.

When everything is available, you can transgress!

Installing an additional pump on a VAZ 2114 - step-by-step instructions

1. The first step is to disassemble our add-on. pump, this is done in order to improve the tightness of the connections. Remove the rubber gasket and coat it generously with sealant. As many who have done this procedure write, over time the rubber gasket begins to leak, so it is necessary to “seat” everything with sealant. Instead of standard fasteners, I decided to use studs with nuts of suitable diameter.

1. Installation of an additional pump. In most cases, everyone recommends draining the antifreeze, but I was able to complete the installation without the need to drain the coolant. The connection looks like this: we take the “original” pipe that goes from the stove to the pump and connect it. The L-shaped part of the hose that goes to the block had to be cut off, and the pump outlet was connected with another hose. All hoses are secured with clamps, and the pump itself is conveniently located on one of the gearbox fasteners; all that was required was a curved bracket. You can see more clearly what it looks like in the photo.

Step-by-step installation of a pump in a VAZ-2114

Before you begin installing an additional pump yourself, you must first wait until the engine has completely cooled down and drain the coolant. Since antifreeze or antifreeze will still be needed in the future, you need to prepare a clean container of the appropriate size to drain the liquid. Next, installation is performed according to the following scheme:

1. You need to unscrew the screws from the new pump and securely treat the rubber gasket in place of the clamps with sealant. Reassemble everything in the reverse order, but instead of self-tapping screws, use bolts and nuts of the appropriate size for better and more reliable fixation.
2. Next, you need to determine the most suitable place to install the new equipment. According to experts, the pump can be installed:

• on the washer reservoir retainer;
• on a pin located near the battery;
• on the fastener located on the engine shield.

When installing an additional pump, it is necessary to pay attention to the location of the horizontal pipe, the front side of which should be directed towards the block.

1. Hoses. To install the hoses in the additional pump, you need to disconnect them from the standard stove and the pipe that comes out from under the manifold. Using a reinforced or aluminum hose of the required length, the hoses are connected to the stove and additional pump. And to connect the hose to the manifold, you will need a small adapter to prevent bending. It is imperative to secure the connections with special clamps and carefully check the reliability of the fixation.
2. To put a new pump into action, you need to install a button to activate it. You can get complete information on this issue and study the connection diagram from a video tutorial conducted by experts in their field on the web resource.
3. The operation of the new device is checked. To check how the additional pump works, you need to fill in the coolant and, if necessary, add more antifreeze. Next, you should start the car’s engine, wait a few minutes for it to warm up, and activate the button to start the new pump.

If warm air enters the cabin, it means that the car owner has successfully installed an additional pump, and now the interior of his car will be warm even on the coldest frosty day.

It is quite easy to install an additional heating device in a VAZ-2114 yourself, and in case of any difficulties, car enthusiasts can watch a video on the Internet, in which they can easily find the answer to any question regarding the installation of an additional heating device.

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.

Approximate procedure for installing an additional pump

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

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

Installing a button

Replacing the heater tap on a VAZ 2114, which one is better to install?

If you decide to acquire additional control for this modification, you will have to fool yourself further.

Voltage + can be taken directly from the battery, but we must not forget about the fuse on the wire where the sealed holder hangs.

In short, the installation is simple:

• remove the panel;
• disassemble it and remove the backlight button;
• we replace its contents with what we need and collect it back.

But in practice, everything is not so simple and this algorithm requires several clarifications:

1. We remove the rheostat (in principle, you can throw it away, it is no longer needed).
2. The wiring is heat-shrinkable and attached for convenience to the rest of the wire bundle.
3. We prepare the negative (we look for it in the area of ​​the dashboard) and positive (you can take it from the ignition) terminals.
4. We find a vacuum booster, install a relay in its area, and then pull the wire from it into the interior to the button.
5. The electrics are connected, we connect everything on the button, and then we put the dashboard back together.
