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.

Electric power steering for VAZ 2114

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.

Installation instructions

Installing the main unit

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.

1. Remove the casing with switches and ignition switch.
2. Unscrew the bolt on the rail and remove it. We need to determine how much larger the “native” part is than our new one.
3. We install the shaft on the EUR. After this we attach the shaft itself in its place.
4. 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.

1. 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.
2. Similar procedures must be done with the gray wire.
3. We connect the power ends. In the battery we connect the pink one is a plus, and the black one is a minus.

The installation is now complete. If you did everything carefully according to the instructions, you will enjoy the ease of driving the VAZ 2114.

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.

The EUR performs several tasks.

1. It has a positive effect on handling, maneuverability, perfectly holds the car on the road, and allows you to feel the car. Remove the electric booster, and driving becomes a complete test of the driver's nerves and physical fitness.
2. It copes well with temperature changes, which are especially typical for the Russian climate. Even extremely low temperatures do not affect the electric power steering, which allows the entire steering system of the car to adequately withstand such operating conditions.
3. The power from the electric booster has a positive effect on fuel consumption. By adjusting the degree of gain, you thereby control the appetite of your car. So the appearance of EUR on the VAZ 2114 became a landmark event for the domestic automobile industry.

Power steering

The hydraulic booster includes a large number of elements that require not only constant monitoring, but also careful handling.

The operating principle of the power steering is based on the interaction of the steering with the oil fluid, which is contained in a special container. This is where the name of the type of amplifier comes from, since the work is based on the force of the working fluid.

Despite the rather complex technology, power steering is effective, safe, provides comfortable control, and allows you to control the behavior of the car even if the front wheels break down.

Alas, the hydraulic booster is not without its drawbacks. The main one is frequent breakdowns. They arise mainly due to leakage of working fluid.

The functions of the power steering are as follows:

• The car becomes more obedient, maneuvers well, and responds to the driver’s steering input;
• Provides softening of impacts on the steering wheel when passing difficult road sections. There are more than enough of these in our country;
• The hydraulic booster is ideal for regular driving on country roads. In this component, the electric amplifier is significantly inferior to the power steering;
• The driver feels the road better, makes timely decisions, and the system responds to them;
• Strengthening due to the working fluid allows you to reduce the number of revolutions of the steering wheel rim to perform maneuvers. This saves the driver's effort.

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.

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:

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.

Installation process

As you know, all foreign-made cars are equipped with power steering, which is initially included in the basic configuration of the car. But with the domestic auto industry, not everything is so simple. So, almost all cars, on the contrary, are not equipped with this design, and the function comes as an additional option, for some money.

EUR or power steering - which is better to choose for a VAZ-2114?

So, should you install a hydraulic booster or an electric booster? This question plagues many motorists. Of course, in all respects, the EUR is inferior to the power steering, but there is one that negates all the advantages of the “hydrika”. This indicator is the price.

So, an electric power steering with installation will cost 20,000 rubles, while a power steering kit without installation costs 25,000 rubles. So, as practice shows, most motorists choose to install electric power steering.

Installation and connection of the EUR steering wheel from Priora in VAZ 2113, 2114, 2115

I rode my father’s viburnum and realized that there was no escaping progress, especially since I plan to change the rack by 3.2, or even 2.5 turns, and without an amplifier there will be no life at all. I bought it at Stinger. The kit includes everything you need: 1. The amplifier itself (a new model, not glitchy in short). 2. Adapter. 3. Steering shaft. 4. Wiring. From myself: 1. I don’t see any problems with the mechanics. 2. For electrical purposes, you need to look for a connection diagram.

I started to disassemble: 1. Removed the steering casing (nothing complicated). 2. Disconnected and removed all switches (wipers and lights). 3. Removed the ignition switch (the first problem is that you need to unscrew the bolts with a chisel, since there are no edges (!). 4. Use a chisel to straighten the clamp securing the shaft and steering rack (at the engine shield). 5. Use a chisel to unscrew the two bolts securing the steering column (also quite inconvenient). the adapter is attached, I'll clamp it in a vice and knock it out through the sleeve). 10. Measured so that only a little bit came out of the nut and sawed it off (you can use a grinder, I made do with a saw and a file). EUR to the adapter (four nuts for 13 plus growers). 14. Replaced the ignition switch (I used hex bolts, it’s more convenient).

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.

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.

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.
