2001 was the year of the appearance of a new project from the domestic automaker AvtoVAZ. The model had two names - Samara-2 or VAZ 2114. In fact, it was an improved version of the well-known nine.
EUR kit
The modernization turned out to be very serious, affecting literally all components of the car. The steering system was no exception. Unlike many other models produced by AvtoVAZ, the 2114 offered a choice of two power steering units - hydraulic power steering and electric power steering .
How to install power steering on a VAZ 2114
From its very production, the steering system of the VAZ 2114 car assumed the possibility of installing power steering using an installation kit.
This also applies to electric power steering or simply EUR. This modification will make it easier to turn the car and increase comfortable handling. This is especially true for drivers who drive in the city most of the time.
The main difference between power steering (power steering) and electric power steering is that the strength (efficiency) of the former directly depends on the speed of the engine. At high speeds, turning the steering wheel is too easy. This affects both ride feel and handling.
To overcome such problems, the power steering is not connected directly to the motor, but using a gain regulator. This is exactly the functionality that an electric amplifier has. The operation of the electric power steering is not characterized by a direct connection between effort and motor power, which allows it to be used as much as necessary in a specific situation.
For the VAZ 2114, a similar EUR is suitable as for the Lada Priora.
Additional advantages of using an electric booster instead of power steering:
- Less maintenance requirements (no need to monitor oil, connections).
- In cold weather there is no need to warm up, as when using power steering.
- Installing the EUR is much easier (no need to interfere with the engine compartment).
- High reliability.
- The only downside is the lower power, although on passenger cars like the VAZ 2114 this is not at all noticeable.
Change of oil
So, opening the hood we can see the first and most noticeable element, which includes the power steering. In general, the remaining elements fit into the steering gear housing and are no longer distributed throughout the engine compartment and car body. We will also immediately need some kind of container into which we will drain the already used liquid. Anything can fit, even a bucket, even a canister. We do not recommend that you throw away the drained oil; it will be quite useful in some minor repairs just for lubrication. Under no circumstances should you add it to the already new oil of your VAZ 2114: the oil must be homogeneous. You also need to let the car engine cool down so that everything cools down and if the oil gets on your hands, it doesn’t burn your skin.
Now we need to drain the oil from the expansion tank. To do this, you need to uncork the lid and carefully pull out the hose that sticks out at the bottom of the tank.
In its place, you immediately need to insert the hose that is lowered into the container that we prepared in advance to drain the already used liquid. Now, under the influence of gravity, the oil will slowly ooze into our container.
The next step is to start the engine, and you immediately need to start turning the steering wheel from side to side so that the pump begins to pump oil through the system through the tank, and little of it will be poured into the container. This procedure must be done until the power steering stops working and the steering wheel stops moving. Thus, it turned out that there was no fluid left in the steering system of the VAZ 2114.
Now you need to immediately proceed to pouring new oil. We must turn off the engine and return to its place the hose that was originally at the bottom of the tank. Fill two-thirds of the oil tank level and start the engine. Now you need to turn the steering wheel again from side to side so that the power steering is pumped with oil and the air is released from the system.
You also need to leave the tank lid open to allow air to escape. As the liquid leaves the tank, we will need to add oil. You will have to turn the steering wheel until the oil stops leaving, after which you need to tightly seal the tank.
That's all, this is exactly how the working fluid is replaced in the amplifier of a VAZ 2114 car. As you can see, there is nothing complicated about it, you can easily do it yourself and even without help. The oil must be selected carefully so that it is ideally suited to the design of this car.
Installation instructions
When installing an electric power steering, it is necessary to take into account that it will be necessary to replace the steering column of the VAZ 2114 with an “electrically driven column”. To do this, let's start with the wiring. You will need to deal with the pads. There will be no need for any “twists”. There is a terminal in the block that we need to remove and insert into the block in the harness.
We insert the free terminal of the harness exactly into the place where the standard wire was. You don't need a special harness for this. Connect two 4 square wires to the battery. Don't forget to connect a 50A fuse. The “weak point” will connect to the tachometer, speed sensor, ground, K-line and wiring to the warning lamp. Don't forget to check the presence of speedometer and tachometer signals.
- Remove the casing with switches and ignition switch.
- Unscrew the bolt on the rail and remove it. We need to determine how much larger the “native” part is than our new one.
- We install the shaft on the EUR. After this we attach the shaft itself in its place.
- Setting up the wiring. We stretch two cables to the battery from the passenger compartment, preferably through the left wing. To conduct wiring you can:
- First remove the washer fluid reservoir.
- Take a solid wire and drag it through, trying to get to the hood.
- As soon as it appears near the hood, we attach our wires to it.
- We pull it out together with our wire.
- We connect the EUR electronics. There is a red connector under the instrument panel with an orange wire in it. It is to this that you need to connect the electric amplifier.
- Similar procedures must be done with the gray wire.
- We connect the power ends. In the battery we connect the pink one is a plus, and the black one is a minus.
Possible problems
Some drivers note that in a VAZ 2114 with a hydraulic booster, the control system becomes as if weightless. This can be confusing. When the gain is lost, the steering wheel has to be turned more often.
A fairly common problem caused by the fact that the hydraulic booster operates directly from the power unit. In order to correct the situation, the hydrach is connected not directly to the engine, but using a gain regulator. Another option is to use an amplifier with an electric drive function. Today, such a device is not difficult to find, and it costs relatively little.
Wiring
As for replacing the hydraulic booster with an electric booster, this is a more than possible option for improving the car. It is considered one of the simplest but most effective types of technical tuning. However, it is strongly not recommended to perform such operations yourself.
Choose specialized car services that specialize in technical modifications and tuning of the car. AvtoVAZ cars, which include the VAZ 2114, are beautiful because they are literally created for tuning. Many young drivers choose the “fourteenth” model as their first car. This is due to the wide possibilities for modification with minimal investment. This car lends itself perfectly to external tuning, and the current spare parts market makes it possible to improve the internal filling. This includes replacing the power steering with electric power steering.
Adjusting the steering wheel position
If you don’t like the height and position of the steering wheel, then you will need to grind the edges of the shaft to the size you need or install gaskets between the plate and the body. It is worth remembering that the electric power steering is automatically switched off at speeds above 50 km/h, unlike the same power steering.
Installing electric power steering on your own is quite possible. You just have to remember that even for an experienced driver it will take a lot of time and effort. But for a lover of comfortable driving, the result will justify all costs and hopes.
Power steering (power steering) on VAZs appeared only starting with the VAZ 2110, while owners of the VAZ 2109 can only be content with steering without power steering. Not everyone is ready to put up with this, so people independently install the power steering from the VAZ 2110 (2112) to the “nines”. In this case, we get not only less effort on the steering wheel, but also a rack with a lower gear ratio - 2.8 turns instead of 3.8, which contributes to faster steering.
Let's look at how you can do this yourself in this article. This article will consist of two parts, in the first part we will look at the installation of the power steering pump, in the second - the installation of the steering rack under the power steering.
Go. First, remove the generator with bracket:
The pulley for the generator belt needs a ripple pulley, as in the figure below, so if there is another one, then we change it to this one:
This is what the VAZ 2110 power steering pump looks like together with the bracket:
The bracket needs to be modified, namely, unscrew the engine mount, saw off the ears of its mounting, and also saw off the far right mount (it gets in the way). In the end it should look like this:
Next, instead of the generator, which we will install above, we install a power steering pump:
As you can see, the second bolt will need to be shorter.
Next, we install the generator bracket, in our example it was taken from Kalina, with a tensioner. This is what it looks like assembled with the generator:
The bracket is installed with 3 bolts in standard places:
Our generator is also from a VAZ 2110. To install it, you will have to cut the “TV” a little:
Next we install the generator and belt. You need a belt marked 6PK975 (or 970).
VAZ 2114 cars are supplied for sale with steering systems that allow the installation of a hydraulic or electric power steering wheel. The EUR is a unit used to ensure smoother and, importantly, comfortable driving by easily turning the steering wheel. You can learn more about how to install the EUR on a VAZ 2114 from this material.
Electric power steering (EPS)
If you want to buy a reliable electric power steering (EPS) for VAZ cars, the RS-MOTOR.RU online store is waiting for you!
Cars have become mandatory attributes of the life of modern people, significantly increasing the level of its quality. Manufacturers are constantly improving cars, making them more comfortable, in particular, by installing electric power steering. As you might guess, this is an abbreviation that stands for: electric power steering.
EUR: device and installation options
We are talking about electromechanical systems that reduce the control forces that drivers are forced to apply to the steering wheels.
Device
Structurally, electric power steering consists of several elements, represented by:
- a steering shaft combined with a torsion bar shaft;
- electric motor;
- electronic control unit (ECU);
- contactless torque sensor;
- rotor position sensor.
Location options
Note that there are two options for the location of electric power steering. So their localization places can be:
- steering shaft, which provides reinforcement to the driver's shaft directly from the steering wheel;
- rack shaft - in this case, the rack itself is strengthened, thereby avoiding overload of the steering shaft and its joints.
ELUR communicates with other electronic systems, which allows it to:
- facilitate the parking process;
- keep the car in the lane;
- stabilize the car in different situations, for example, if it is necessary to go around a suddenly appeared obstacle.
About the benefits of using electric power steering
EURs have significant advantages:
- efficiency, since their installation helps reduce fuel consumption to 0.8 liters per 100 kilometers;
- quiet operation;
- ease of maintenance, which is due to the simplicity of the design of the electric amplifier;
- compactness, which allows you to install this device on the steering shaft, which means that you do not need to look for additional space under the hood of the car.
Installing electric power steering opens up a lot of additional opportunities for drivers aimed at increasing the comfort of car operation.
The feasibility of installing EUR
Does it make sense to install power steering (power steering) or power steering on the “four”? In this case, it is impossible to give a universal answer, since it is unique for each motorist. Of course, with power steering or electric power steering, the process of turning the steering wheel will be easier, making driving more comfortable. But there is another side to the issue - firstly, the cost of the power steering or electric power steering kit, as well as the rather complicated installation of the system yourself. In general, it’s up to you to decide, but if you decide to install an electric booster on your car, we will help you with the installation.
Types and advantages of power steering
The steering of the VAZ 2114 has undergone significant changes when compared with its predecessors in the form of the first generation Samara. Driving has become really better.
Installation kit
Customers had the opportunity to choose between electric power steering and power steering, that is, electric power steering and power steering. But how do these systems differ from each other, which one should you prefer and why? Let's try to figure this out.
Electric booster
Electric power steering operates using pulses of electrical current. This is a rather complex system in which each individual part has its own important role. Because of this, when at least one unit fails, the operation of the entire device is disrupted, it can completely stop working.
Electromechanical amplifier circuit
The task of the car owner whose car has an EUR installed is to constantly monitor the condition of the unit. A special controller is responsible for the operation of current pulses. With its help, the driver can independently set the degree of gain.
Detailed Installation Guide
So, if you decide to install electric power steering on a VAZ 2114, then you need to take into account that you will also have to replace the steering column itself. In particular, instead of a standard device, you will need to install a column with an electric drive; accordingly, our repair process will begin with the wiring. You will need to deal with all the connectors and connectors, because you must do everything beautifully, without any twisting of the wires. The block has a special terminal that you will need to remove and then install it on the connector in the harness.
The free terminal of this connector is installed in the place where the standard wiring ran; no special harnesses or adapters are required for this. You only need to connect two 4 square cables to the battery. To ensure the safety of this section of the electrical circuit, it is additionally necessary to install a 50 ampere safety element.
Next, using the so-called weak current, that is, not a power wire, you need to connect to the following elements:
- tachometer, used to display the number of revolutions of the engine crankshaft;
- a speed sensor used to indicate the speed of the vehicle;
- mass, that is, the car body;
- diagnostic K-line;
- as well as to the control light (the author of the video about installing the unit at home is the sokur64 channel).
After completing these steps, you will need to diagnose the presence of a tachometer signal, as well as a speedometer.
If there are signals, then the further installation procedure is as follows:
- The plastic casing on the steering column, where the switches are installed, as well as the ignition switch, is dismantled. To do this, you need to unscrew all the bolts that secure the protective cover.
- Then you need to unscrew the screw installed on the rail and dismantle it. At this point, you will need to determine how much the size of the assembly installed during production differs from the size that will be used.
- At the next stage, the shaft is mounted directly on the electric amplifier. After this, the shaft itself must be fixed at the installation site.
- The next step is to configure the electrical circuit. It is necessary to run two wires from the vehicle interior to the battery; alternatively, this can be done through the left fender. To do this, you must first dismantle the expansion tank of the washer system, and then, using the hardest and thickest wire, stretch it. You need to try to get to the engine compartment.
- When the end of the wire appears in the engine compartment, you need to attach the wiring to it. Next, both wires will need to be pulled out along with the wire itself.
- Having completed all these steps, we proceed to one of the main steps - connecting the electric amplifier electronics. Under the dashboard in the “four” there is a special red block, inside of which there is an orange cable. The EUR contact itself must be connected to this wire. The same actions are performed with the gray wire.
- Then the power ends are connected. Pink and black wires are connected to the battery, pink to the positive terminal, black to the negative. At this point, the installation process can be considered complete. Check the functionality of the installed system and, if necessary, adjust the device.
conclusions
The process of installing electric power steering on a VAZ-2114 is quite long and not just a process that will require a lot of time and effort. Of course, to many motorists, it will seem quite complicated and almost impossible. Therefore, if a car enthusiast is not confident in his abilities, he needs to contact a car service center, where everything will be done quickly enough.
The VAZ 2114 car is one of the most used and purchased today. This is a modification of the same “nine” that became widespread right from the release of the first series from the factory assembly line. The same car received a lot of new products at its disposal: from an injection engine and a soft suspension to softly comfortable seats.
The nuances of adjusting the steering wheel position
If you are not satisfied with the position of the steering wheel or its height, this can be corrected by adjustment. To do this, it is necessary to grind the edges of the industrial shaft to the required dimensions or install gaskets between the device body and the plate. When making adjustments, you must remember that the EUR itself is automatically turned off when the vehicle speed exceeds 50 km/h.
Price issue
The cost of electric power steering for a VAZ 2114 car may vary, depending on the store where it is purchased, as well as the region of the country. On average, the price for a complete system set varies around 22-24 thousand rubles. On the Internet, you can search for stores where the EUR kit is sold on promotions - with a discount from the seller, you can purchase the unit for 20 thousand rubles.
Disadvantages of power steering and electric power steering
Connection
To answer this question, it is necessary to consider not only the positive aspects of this or that amplifier, which we have already done, but also point out their main disadvantages.
What is better for the VAZ 2114? Let's try to figure this out.
With this short list the list of shortcomings can be completed. But it is worth paying attention to some nuances.
To install power steering on a VAZ 2114 you will need:
- power steering pump,
- bracket for mounting the power steering pump,
- generator bracket "Kalina",
- rivulet belt 960 mm long,
- alternator belt tensioner rocker arm,
- generator belt tensioner roller "Kalina",
- bushings,
- interior boot of the VAZ steering wheel with power steering,
- petrol and oil resistant hose D 12 mm. 2 meters and D 16 mm 1 meter,
- power steering fluid reservoir,
- clamps for petrol and oil resistant hoses,
- nylon clamps,
- bolts, washers, nuts,
- power steering oil,
- generator belt tensioner "Kalina".
Power steering for 2115 - review
I bought a power steering kit from 2110 - it included almost all the related spare parts.
In addition to the generator bracket, you need a Granta with a tensioner. Later I bought it. The original generator fits there without any problems.
We remove the old rack and steering column. For convenience, I dismantled the receiver and VUT. It can be easily pulled out through the side holes of the tie rods.
To connect the new rail to the seats, you will have to cut a hole into the interior, otherwise there is no other way. I got it like this, then I’ll cover it with a duster.
Now about the nuances, I will also talk about this in the video. It is necessary to file the pump bracket, as it will rest against the engine support.
I installed the original steering rods, pressing in the 2110 steel blocks, since the original ones have a protrusion and have a smaller mounting hole.
About the steering column, I simply dismantled the old one and installed one from 2110, without any extensions or filing of the steering shaft. Everything fits bolt to bolt.
I routed the lines, replaced the return line with a resistant hose for gasoline oil, since the original 2110 pipes do not fit structurally.
The high pressure hose ran down the bottom, next to the gearbox. The fastener came out very well, just the perfect place. We fix it to the ignition coil bolt, next to the starter.
Location of the power steering reservoir - I decided to place it near the right pillar, probably the best place. I haven't decided on the mounting yet.

Types of devices
Power steering is a device with which the working fluid creates pressure on the steering rack. Due to this, the driver needs to apply much less force to the steering wheel to move it. There are several types of such equipment, let's look at the main disadvantages of all other models of amplifiers and it will become clear why the power steering was installed on the VAZ 2114, and, in general, on most modern cars. In addition to this, there are such options in the world:
- Electric.
- Pneumatic.
- Mechanical.
The first option is next after the hydraulic one in terms of its prevalence. Its action is based on the use of magnetic forces to rotate the steering axis. But there is also a noticeable disadvantage here - the energy consumption of the battery, which immediately begins to affect the fuel consumption of the car.
The pneumatic one is very complex; there are a lot of elements: a cylinder, a compressor, pipelines and pipes, a reinforcing mechanism, etc. This entire design is very unreliable and the slightest malfunction in the operation of at least one component leads to the absence of an effect as such. The mechanical amplifier looks like a set of different gears in the body and its effect is achieved due to a changed rotation ratio, here there is minimal gain.
Power steering VAZ 2114
That is why today you can most often find power steering on a car; it was precisely because of its reliability, simplicity and efficiency that it was chosen for installation on the VAZ 2114. The most dangerous breakdown that can happen is a leak of working fluid. Next, we will look at how to correctly understand and determine the location of the leak in the system and how to correctly replace the working fluid in a VAZ 2114.
