Changing the oil in a VAZ hydraulic booster on your own is difficult, but possible. What kind of oil to fill in gur The volume of oil in the power steering VAZ 2112

Many today use a VAZ 2110 car. Not everyone knows which power steering oil to choose.
The correct operation of the GRU contributes to the fact that driving a machine is a comfortable and safe process. However, in order for the hydraulic booster to function normally, it must be serviced on time.
Most often, the manufacturer gives advice on the oil that must be used for the normal operation of this system. The brand of power steering oil VAZ 2110 is of great importance.
However, most drivers remember the need to change the oil only after the failure of the GRU.

Signs of breakdown

Most often, the following signs indicate that the hydraulic booster is not working properly:

When rotating, incomprehensible sounds are made that were not there before;
Steering wheel rotation is slower than before. In addition, the driver has to exert more effort when it rotates than before.

Note: These problems can also appear as a result of other problems. Therefore, before starting the repair of the GRU, you need to figure out whether the problem is really with it.

Power steering service

In order for the machine to always function normally and there were no failures during its operation, it is necessary that the driver service it in a timely manner.
However, this service must be correct. works due to oil, so it is very sensitive to the state of such a liquid.
Here are some tips for maintaining it:

The oil should be changed at least once a year. Especially often you need to change the oil for those who use their car too intensively.

Note: otherwise the hydraulic booster will stop working properly, so it will need to be repaired or even replaced, which will cost much more than buying new oil.

In addition, in addition to a complete oil change, it is sometimes necessary to add it. Very often, the oil level becomes below the required level.
Therefore, it must be topped up to the maximum mark. With frequent topping up, it turns black. This indicates the need to replace it.

Operating rules

In order for the hydraulic booster to serve for a long time, during its operation it is necessary to observe the following rules:

In winter, it needs to be warmed up, otherwise under the action hard frost it may crack. It warms up easily.
To do this, you just need to twist it several times, first to the right, and then to the left. In this case, the amplitude of rotation should not be too large.
If the power steering is faulty, then you can not drive a car in any case.

Note: This will lead to an emergency on the road, as the driver may not be able to turn off in time.

If the level is below the norm or it is not there at all, then the use of the machine in this case is prohibited.
Do not hold the steering wheel in the most extreme positions for too long. Because of this, the pump is overloaded.

Note: so that the load is not so strong, you do not need to hold the steering wheel in extreme positions. It is enough to take it just a few cm back.

How to choose power steering oil

Usually, for any model, the manufacturer gives recommendations on which one needs to be filled. In no case should cheap oils be poured into the top ten, as this will lead to the timely failure of the machine.
This is due to the fact that they do not have enough of the protective properties that the GRU needs.

Note: in some cases it is necessary to fill in this system usual engine oil. But this should only be done in emergency situations.

How to understand that the hydraulic booster needs to be replaced

It is necessary to start replacing the GRU system only if:

There is an oil leak in the system;
The steering wheel turns much harder than it used to;
The oil had a smell reminiscent of burning;
On increased speed the steering wheel turns easier than at idle;
There are extraneous sounds in the system.

Note: any part can wear out due to the fact that the oil is not changed on time.

Which oils to choose: mineral or synthetic

Exist different kinds oils. Naturally, mineral oils are much more expensive than synthetic ones. However, they have many more useful properties.
There are many rubber parts in the power steering system. Synthetic oils have a bad effect on rubber, as they are quite aggressive (this cannot be said about mineral oils).
Such oils can only be poured into this system if its parts are designed for this.

Changing the oil in the system

Having decided to independently change the oil in the system, you must perform the following steps in the exact sequence:

Unscrew the cap of the tank where the oil is located.
Pump out the liquid present here. To do this, you can use a syringe with a thin tube.
Fill with new fluid to the highest possible level.
Start the engine and turn the steering wheel left and right a few times.
Stop the engine

However, there is another way that will allow you to completely pump out all the liquid from the system.
For this:

Drain fluid from reservoir.
Loosen the clamps on the hoses that go to the tank.
Remove hoses and tank. It needs to be washed.
The hose from the steering rack should be put at one end in a plastic bottle.
Turn on the engine. Turn the steering wheel left and right. This will remove excess fluid from the system, which will flow through the hose.

Note: before starting work, you can hang the front of the machine, which will make it easier to turn the steering wheel.

The second hose should be inserted onto the funnel. Pour new fluid through it.
Collect everything in reverse.

You can change the oil in the power steering system with your own hands. Before starting this procedure, you should review the photos and videos on this topic, of which there are a lot on the Internet.
In addition, our instructions can help. It is noteworthy that the price of new oil is much lower than the cost of repairing the entire GRU system, which can break down due to the fact that the oil has not been changed for a long time.

How to replace the power steering fluid on a VAZ car without the help of others

Before proceeding to self replacement fluid in the hydraulic booster (Power Steering) of your VAZ, read the manufacturer's information about the types and brands of water used in the car. Most models use Pentosin Hydraulic Fluid CHF 11S VW52137.

I want to see that the procedure for replacing the fluid in the power steering is not easy and will take you no more than an hour. And so, let's get started.

We hang the front of the car on a jack and substitute an emphasis under the front of the thresholds.

Then, using a syringe with an extension cord in the form of a plastic tube, we pump out the used fluid from the power steering reservoir. After the liquid in the tank runs out, turn the steering wheel all the way to the left. The oil in the reservoir will reappear. We pump it out and turn the steering wheel all the way to the right. We pump out the liquid that has appeared again.

We perform this procedure until the liquid in the power steering tank is completed

Next, remove the hose that comes from the passenger compartment and enters the tank (shown in the figure with a short arrow), and then turn the steering wheel from side to side, a certain amount of oil should come out. Changing the oil in the gearbox VAZ 2114: how many liters. After that, a couple of times we turn the control wheel in different directions until it stops, which will get rid of the remaining oil in the system. And then we put the hose in its place.

Now let's start filling hydraulic system new oil. In this case, we take oil for power steering Castrol ATF Dex II Multivehicle. We need about 800 grams.

Pour the liquid into the reservoir to the maximum level and begin to scroll the steering wheel all the way, first to the left, then to the right.

Now we start the engine for a while and turn it off. Then we turn the wheel again. During these operations, the liquid in the tank will decrease, do not forget to add it.

At the end, we perform pumping and removal of air from the power steering. To do this, turn the steering wheel on a muffled car 10 times in each direction. Then the same with the engine running.

After changing the fluid in the power steering, you should feel that the steering wheel has become much easier to rotate _

There is another way to replace the fluid in the power steering. Its essence is to replace the old oil with new. This method is of better quality, since it is possible to completely get rid of the old oil, but at the same time, the new one will need twice as much.

For this procedure, you will need an assistant 1. We pump out the liquid from the power steering reservoir; 2. Remove the return hose from the tank and turn it off, for example, with another hose with a pinched end; 3. We put on another hose on the return line and bring it out under the car into a previously prepared container; 4. Pour liquid into the tank to the maximum level, the assistant starts the engine; 5. As soon as the liquid leaves, the assistant turns off the engine at your signal; 6. Pour the liquid again to the “MAX” mark and repeat the procedure until clean liquid flows into the prepared container;

7. We put the return hose back on and add power steering fluid to the desired level.

And in conclusion, we suggest that you familiarize yourself with the procedure for replacing power steering hoses on a VAZ car

Changing the oil in a VAZ hydraulic booster on your own is difficult, but possible

Changing the power steering oil VAZ

As practice shows, such a procedure as changing the oil in the power steering of the VAZ 2112 is little known to most motorists. What can I say, many do not consider it necessary to waste their time and money on servicing a node that works without comment, with constant accuracy and without extraneous sounds. Such reflections, as a rule, lead to disastrous results, and the cost of irresponsibility of the car owner may not be comparable with the cost of periodic maintenance. In order for you to understand how important it is to replace the power steering oil VAZ 2112, I suggest in general terms get acquainted with the device of this complex and expensive node.

Device and principle of operation

Purpose

Modern automotive industry has long since moved from pure mechanics in the drive mechanisms to various types of amplifiers: hydraulic, pneumatic and electric. Steering gear modern car equipped with amplifiers of both electric and hydraulic type, which greatly facilitate driving by reducing gear ratios in the steering gear. The power steering faces several difficult and very important tasks:

Due to the properties of the elasticity of the liquid, it absorbs the shock load received from road irregularities (affects the straightness of movement);
By adjusting the pressure, change the force applied to the steering wheel by the driver (contributes to the “feel of the steering wheel”).

Design

The steering gear with hydraulic booster consists of:

Power steering pump and hydraulic fluid reservoir. The pump is driven by crankshaft engine through drive belt;
The steering mechanism itself, consisting of a spool-type control unit and a hydraulic cylinder made in one housing;
The low and high pressure pipelines connecting them.

Steering gear with hydraulic booster

Principle of operation

This system uses a vane type pump.

Pump

power steering pump

The principle of operation of the power steering pump

When the shaft rotates, the blades move along the “elliptical” body of the pump stator, clinging to it due to the rotation of the shaft centrifugal force. The elliptical shape of the stator, in turn, allows you to change the volume of fluid between the blades and the housing, which creates significant pressure. That is, with a large volume, the “suction” of the pump occurs, with a decrease in the “pressure” of the liquid.

Since the pump is driven by the engine crankshaft, its performance is directly dependent on engine speed. A constant design pressure is provided by a discharge valve.

Steering gear

Animated video of the operation of the hydraulic cylinder

During rectilinear motion, all valves of the system are closed, and the liquid circulates along the circuit, without entering the power cylinder, into any of its chambers. Applying force to the steering wheel, by means of the twisting torsion bar of the spool chamber, one of the chambers (left or right) opens and the liquid, being injected, helps the driver to turn the steering wheel.

The principle of operation of the power steering

I hope now you understand the importance of the quality of the oil in the VAZ 2112 power steering system and what is timely Maintenance of the above devices is urgent. Further, your attention is invited to instructions on how to change the oil in the hydraulic power steering system of your car with your own hands.

Before starting work, you need to find out what brand and what type of hydraulic oil is used in the power steering system in your car. I would like to note that this procedure is not anything complicated and will not take you much time. So:

We hang out the front of the car, not forgetting to substitute reliable stops under the thresholds;

Attention! Also don't forget to put rear wheels car wheel chocks and put it on parking brake.

Using a syringe and an extension cord put on it, we pump out all the liquid from the tank;

Pumping hydraulic fluid from the reservoir

Advice! After the fluid in the tank is over, turn the steering wheel all the way to the left (it will be squeezed out of the working cylinder into the tank) and to the right until the liquid in the tank stops appearing.

Then, fill the hydraulic fluid into the reservoir to the maximum level and begin to pump the steering wheel all the way to the left and right, adding the required amount of oil in the process;
We start the car and repeat the operation of turning the steering wheel;
The last “touch” is the bleeding of the system, that is, the removal of air from it, for which, on a muffled car, we scroll the steering wheel from lock to lock 10 times in each direction.

In addition to this method, the hydraulic fluid can be replaced by displacing the old fluid with new fluid. This method is considered more effective, since it allows you to completely get rid of the remnants of used oil, although it will need twice as much. The essence of this method is as follows:

We pump out the liquid from the tank "according to the old scheme";
We remove the return hose from the tank and “muffle” the released fitting;
We bring the “return” hose to the side, under the bottom of the car into a previously prepared container, having previously lengthened it with an additional hose;
Pour the liquid into the tank and start the engine, as soon as the liquid leaves we turn off;
We repeat this procedure until clean oil flows from the return hose into the prepared container.

Advice! In this case, it is best to work with an assistant, since there is a high risk of emptying the tank and trapping air with the pump, and it will simply be more convenient and faster.

Finally, we put the return hose on the tank fitting and bring the hydraulic fluid level to the desired level.

After changing the oil in the VAZ 2112 power steering, pay attention to how much easier the steering wheel began to rotate, and how much “softer” the booster pump began to work. I would like to remind you once again that you do not forget about the periodic replacement of the hydraulic fluid in the power steering system and change it every 30,000 kilometers or every two years of vehicle operation.

Priora Power Steering Oil Change - Community "VAZ: Repair and Refinement" on DRIVE2

So I decided to change the oil in the power steering, for 5 years of operation it has become completely black.

First you need to raise the front of the car to make it easier to turn the wheels and thereby expel the old oil from the system, I lifted it with 2 jacks.
To pump out the oil from the tank, I bought a syringe 20-ku and connected it to a piece of plastic tube from the washer, you can use the tube from the system or something else, as you like.
Be sure to cover the belts, they do not like oil and deteriorate a lot, I used an ordinary rag, but I think it would be better to use some kind of bag. We begin to pump out the oil into any convenient container
After the oil in the tank is over, we ask a friend to turn the steering wheel making full turns, and we see how oil appears in the tank again, we start pumping it out again. This procedure with turning the steering wheel could be omitted, but as I did for the first time, I did it according to the instructions found on the Internet. Next, I disconnected the return hose, took a smaller bottle, cut a hole in it and sent the hose into it. Again we ask a friend to turn the steering wheel, and we see how the system drives out the remaining oil. As a result, we see how much oil was pumped out and what color it is.
We connect the hose back to the tank, I immediately changed the clamp, because. the old one stopped stretching. It seems to cost 10 rubles. We fill in new oil almost to the edges of the tank. I bought Febi for 370 rubles, an analogue of Pentosin. Of course, Pentosin is better, but it costs more than 700 rubles, and for the first time in the form of flushing the system, it will do. to solve the problem with the hum of the power steering pump and vibration when turning the steering wheel, it is necessary to replace the return hose with a new sample hose, but I have not found it yet, then in the future I will change the oil again.
As soon as the oil is poured into the tank, we ask the comrade to turn the steering wheel again, the oil will begin to go into the system. As soon as it is gone, add oil and ask a friend to start the engine for 5-10 seconds, at this moment we observe how the oil starts to leave again and add it if necessary. bubbles of air expelled from the system appear in the barrel. Add oil if necessary to the desired level and enjoy the work done.
You can also rinse the tank, because. the filter there is probably dirty, but I will do that next time.

Changing the oil in the VAZ power steering makes it easier to turn the steering wheel

1 The design of the hydraulic booster
- 1.1 Changing the oil in the hydraulic booster

Power steering VAZ

The latest models of VAZ cars are equipped with power steering - power steering. Its task is to ensure driving safety by reducing the effort on the steering wheel. In addition, the power steering has other functions:

Reduces the gear ratio at the steering mechanism, which improves the maneuverability of the car.
When driving on a country road, the blows to the hands will be less. If it breaks while driving front wheel, control of the machine is retained.
If the device fails, driving is possible.

An oil change in the power steering on a VAZ 2110 is carried out in case of an oil leak or the expiration of the service life according to technical maintenance, which is 60,000 kilometers of the car or three years of its operation. Performing a timely oil change with your own hands will allow you to keep the complex power steering unit in working condition for a long time.

Hydraulic booster design

The main nodes of the device:

Steering device

Amplifier pump and fluid container. The pump is powered by the crankshaft of the motor through a drive belt.
Steering gear. It consists of a hydraulic cylinder and a spool-type control unit located in one housing.
The devices are connected by pipelines of high and low pressure.

The operation of the hydraulic booster is as follows:

When twisting the torsion shaft relative to its body, the spool rotates. This creates elasticity, which responds to the steering and makes it more comfortable.
The angle of rotation of the spool depends on the applied force on the steering wheel. Increasing the force on the handlebar increases the steering angle, which allows more oil to pass through the distributor assembly. The better the lubricating fluid, the more reliable the operation of the unit.

Changing the oil in the hydraulic booster

Oils for the power steering system differ in viscosity, type of base, additives. The car care instructions suggest that the VAZ 2110 power steering oil be replaced mineral oil. Existing synthetic oils have a bad effect on the durability of rubber parts based on natural rubber, due to chemical aggressiveness. Synthetic oils can be poured into the power steering system if its parts are made of a special rubber composition that is designed for synthetic oils.

Changing the oil gur VAZ 2112 should begin with determining the brand and type of hydraulic oil used in the car. The replacement process itself will take a little time, and the price of the work will be acceptable.

So:

The front wheels are raised so that they are both in the air.

Tip: For the stability of the car, it is necessary to substitute reliable stops under its rear wheels and fix the car with a handbrake.

All liquid is pumped out of the tank. For this, a syringe is used, on which an extension cord is put on, as shown in the photo.

Pumping liquid from the tank

Tip: When pumping out the liquid, when it is gone in the tank, it is necessary to turn the steering wheel to the left to the full, this will squeeze the oil into the tank from the working cylinder, then to the right. Such actions must be repeated until the liquid ceases to appear in the tank.

To the maximum level, new oil is poured into the tank. The steering wheel turns all the way to the right and left. Add the correct amount of oil as needed.
The VAZ engine starts, and the steering wheel turns are repeated.
Changing the power steering oil to a VAZ 2112 ends with pumping the system, which removes air from it. The operation is performed by turning the steering wheel 10 times from lock to lock in each direction.

The hydraulic fluid can be replaced by replacing the old oil with new oil. This method is more efficient, it allows you to completely get rid of the remnants of the previously used oil, but you will need almost twice as much liquid, which increases the cost of work. In this case:

Under the bottom of the car, a container is installed to drain the used oil.
According to the previous scheme, oil is pumped out of the tank.
The return hose is removed from the tank, and the fitting for its fastening is muffled.
The hose, pre-extended with an additional piece, is retracted to the side.
New fluid is poured into the tank and the engine starts. After the liquid in the tank is gone, the engine is turned off.
The operation is repeated until it exits the hose into a container for the return of clean oil.

Tip: To carry out the work, you need to use the services of an assistant. This will prevent the risk of emptying the reservoir, which could cause the pump to entrain air.

A return hose is put on the tank fitting, the hydraulic fluid level is brought to the desired mark.

How the oil is changed in the power steering VAZ 2112 can be clearly seen in the video. After the oil has been changed correctly in the power steering system, the steering wheel will turn much easier, the booster pump will work “softer”.

As practice shows, such a procedure as changing the oil in the power steering of the VAZ 2112 is little known to most motorists. What can I say, many do not consider it necessary to waste their time and money on servicing a node that works without comment, with constant accuracy and without extraneous sounds.
Such reflections, as a rule, lead to disastrous results, and the cost of irresponsibility of the car owner may not be comparable with the cost of periodic maintenance.
In order for you to understand how important it is to change the power steering oil of the VAZ 2112, I suggest that you familiarize yourself with the device of this complex and expensive unit in general terms.
