The fluids used in the hydraulic booster can be divided according to several criteria:
- Colour;
- Composition;
- Variety.
Color classification
It is wrong to be guided only by color gradation when choosing an oil, although this practice is widespread among car owners. It is also often indicated which color of liquid can be mixed, and which should not.
Mixing is contraindicated in liquids in composition and not in color, and since now both mineral water and synthetics can be presented in any color, this information should be treated very carefully.
Red ATF gear oil is usually synthetic, the Dexron brand from General Motors is considered the reference, but there are products from other manufacturers such as Revenol, Motul, Shell, Zic, etc. 
The yellow oil produced and licensed by Daimler is used in Mercedes-Benz power steering systems. It can be synthetic and mineral.
Green oil. Most of them are multifunctional and universal fluids, in composition they can be both synthetic and mineral. They are used in hydraulic boosters, suspension and other systems that operate on liquids. It is impossible to mix with other colors, unless the manufacturer has declared full compatibility, for example, Comma PSF MVCHF is compatible with some types of Dexron. 
Liquid composition
According to the composition of the power steering fluid, it can be divided into mineral, semi-synthetic and synthetic. The chemical composition determines the basic set of functions of the oil:
- Viscosity characteristics;
- Lubricating properties;
- Corrosion protection of parts;
- Anti-foaming;
- Thermal and hydraulic properties.
Synthetics and mineral water cannot be mixed with each other, since the types of additives in them have cardinal differences.
Synthetics
These are high-tech fluids, in the production of which the most modern developments and additives are used. Petroleum fractions for synthetics are treated with hydrocracking. Polyesters, polyhydric alcohols and additives provide them with outstanding characteristics: a wide range of operating temperatures, a stable oil film, and a long service life. 
The main reason why you cannot fill a synthetic-based hydraulic fluid in a power steering intended for mineral power steering is its aggressive effect on rubber products, of which there are many in the power steering. Where synthetics are used, rubber has a completely different composition and is made on a silicone basis.
Semisynthetics
A mixture of synthetic and mineral oils, thanks to which the latter receive significant improvements in characteristics: reduced foaming, fluidity, heat dissipation. 
Semi-synthetic fluids include such well-known fluids as: Zic ATF Dex 3, Comma PSF MVCHF, Motul Dexron III and others.
Mineral water
Mineral oils contain petroleum fractions (85-98%), the remainder being additives that improve the performance of the hydraulic fluid.
They are used in hydraulic boosters, containing seals and parts based on ordinary rubber, since the mineral component is neutral, and is not harmful to rubber products, unlike synthetics. 
Mineral fluids for power steering are the most inexpensive, but they also have a short service life. Mobil ATF 320 Premium is considered a good mineral water, Dexron oils up to and including IID were also mineral.
Different types of oils
Dexron- a separate class of ATF fluids from General Motors, produced since 1968. Dexron is a trademark manufactured by GM itself and others under license.
ATF(Automatic Transmission Fluid) - oils for automatic transmissions, often used by Japanese automakers and power steering.
PSF(Power Steering Fluid) - literally translated as power steering fluid.
Multi HF- special, universal power steering fluids with approvals from most automotive manufacturers. For example, the CHF fluid produced by the German company Pentosin (pentosin) has received approvals from BMW, Ford, Chrysler, GM, Porsche, Saab and Volvo, Dodge, Chrysler.
Can I mix oils
Mixing is permissible, but the manufacturer's recommendations must be followed. Most often, the packaging indicates with which brands and classes of oils one or another fluid for power steering can be mixed.
Do not mix synthetics and mineral water, as well as different colors, unless it is directly indicated. If there is nowhere to go, and you have to pour what is at hand, replace this mixture with the recommended one as soon as possible.
Is it possible to pour engine oil into the power steering
Motor - definitely not, transmission - with reservations. Below we will analyze in detail why.
To understand whether it is possible to pour other oils into the power steering, for example, engine or transmission oils, you need to know what functions it performs. 
The fluid in the power steering must cope with the following tasks:
- Lubrication of all hydraulic booster assemblies;
- Protection against corrosion and wear of parts;
- Pressure transmission;
- Anti-foaming;
- Cooling the system.
The above characteristics are achieved by adding various additives, the presence and combination of which gives the oil for power steering the necessary qualities.
As you understand, the tasks of engine oil are somewhat different, therefore it is highly discouraged to pour it into the power steering.
With regard to transmission oil, everything is not so simple, the Japanese often use the same ATF for automatic transmissions and power steering. Europeans insist on using special PSF (Power Steering Fluid) oils.
What kind of liquid to pour into the power steering
Based on this, the answer to the question "what kind of oil to pour into the power steering" is obvious - it is recommended by the manufacturer of your car. Often the information is indicated on the expansion tank or cap. If there is no technical documentation, call an authorized center and check.
In any case, steering experiments are not allowed. The serviceability of the power steering depends not only on your safety, but also on those around you.

How much oil is in power steering
As a rule, 1 liter of fluid is sufficient for replacement in a passenger car. For trucks this value can be up to 4 liters. The volume may slightly change up or down, but it is worth focusing on these figures.
How to check the level
To control the fluid level in the power steering, an expansion tank is provided. It is usually labeled with MIN and MAX values. Depending on the car brand, the inscriptions may change, but the essence does not change - the oil level should be between these values.
How to top up
The refilling process itself is simple - you need to unscrew the cover of the power steering expansion tank and add enough fluid so that it is between the MIN and MAX marks.
The main problem when adding oil to the power steering is its choice. It is good if the replacement has not yet been made, and the system contains fluid from the manufacturer's plant. In this case, it is enough to check the technical documentation, take the recommended oil and top up to the required amount.
If you do not know what is in the system, we recommend that you make a replacement immediately, because in any case you will have to buy a canister of liquid for refilling.
How to replace power steering fluid on a VAZ car without the help of others
Before you start changing the fluid in the power steering (GUR) of your VAZ on your own, 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 would like to see that the procedure for changing 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 sills.
Then, using a syringe with an extension in the form of a plastic tube, we pump out the waste 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 will reappear in the reservoir. We pump it out and turn the steering wheel all the way to the right. We pump out the liquid that appeared again.
We carry out this procedure until the liquid in the power steering tank runs out
Next, we remove the hose that comes from the passenger compartment and enters the tank (shown by a short arrow in the figure), 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 allow us to get rid of the remaining oil in the system. And then we put the hose in its place.

Now let's start filling the hydraulic system with new oil. In this case, let's take the oil for power steering Castrol ATF Dex II Multivehicle. We need about 800 grams.
Pour liquid into the tank to the maximum level and begin to turn the steering wheel all the way, first to the left and then to the right.
Now we start the engine for a while and turn it off. Then we turn the wheel again. At the input of these operations, the liquid in the tank will decrease, do not forget to add it.
At the end, we perform pumping and air removal from the power steering. To do this, turn the steering wheel on a muffled car 10 times in each direction. Then the same amount with the engine running.
After changing the fluid in the power steering, you should feel that the steering wheel turns much easier _
There is another way to replace the fluid in the power steering. Its essence lies in the displacement of old oil with new one. This method is of higher quality, since it is possible to completely get rid of the old oil, but at the same time, you will need twice as much new oil.
For this procedure, you will need an assistant 1. We pump out the fluid from the power steering tank; 2. Remove the return hose from the tank and muffle it, for example, with another hose with a pinched end; 3. On the return line we put on another hose and bring it under the car into a previously prepared container; 4. Fill the tank with liquid to the maximum level, the assistant starts the engine; 5. As soon as the liquid is gone, the assistant turns off the engine at your signal; 6. Fill the liquid again up to the “MAX” mark and repeat the procedure until the clean liquid flows into the prepared container;
7. Put on the return hose back and add power steering fluid to the desired level.
And in conclusion, we suggest that you familiarize yourself with the procedure for replacing the power steering hoses on a VAZ car

Changing the oil in the VAZ power steering on your own is difficult, but possible
Replacing the power steering oil vaz
As practice shows, such a procedure as changing the oil in the VAZ 2112 power steering is little familiar to most motorists. But what can I say, many do not consider it necessary to waste their time and money at all on maintaining a unit that works without comment, with constant accuracy and without extraneous sounds. Such reflections, as a rule, lead to disastrous results and the cost of the car owner's irresponsibility may not be comparable to the cost of periodic maintenance. In order for you to understand how important it is to change the oil in the VAZ 2112 power steering, I suggest in general terms to get acquainted with the device of this complex and expensive unit.
Device and principle of operation
Appointment
The modern automotive industry has long passed from pure mechanics in the drives for controlling mechanisms to various types of amplifiers: hydraulic, pneumatic and electric. The steering gear of a modern car is equipped with both electric and hydraulic amplifiers, which greatly facilitate driving by reducing the gear ratios in the steering gear. There are several difficult and very important tasks before the power steering:
- Due to the properties of elasticity of the liquid to absorb the shock load received from the unevenness of the road (affects the straightness of the movement);
- By adjusting the pressure, change the force applied to the steering wheel by the driver (contributes to "steering feel").
Design
The steering gear with hydraulic booster consists of:
- Power steering pump and hydraulic fluid tanks. The pump is driven from the engine crankshaft via a drive belt;
- The steering mechanism itself, consisting of a spool-type control unit and a hydraulic cylinder made in one housing;
- Low and high pressure pipelines connecting them.
Hydraulic power steering
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 "ellipse" body of the pump stator, pressing against it due to the centrifugal force created by the shaft revolutions. 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, when the volume is large, the pump is "sucked in", while the "pressure" of the liquid decreases.
Since the pump is driven by the engine crankshaft, its performance is directly related to the engine speed. A discharge valve provides a constant design pressure.
Steering gear
Animated video of hydraulic cylinder operation
When moving in a straight line, all the valves of the system are closed, and the liquid circulates around the circuit, without getting into the power cylinder or into any of its chambers. By applying force to the steering wheel, by means of the twisting torsion bar of the valve chamber, one of the chambers (left or right) opens and the fluid, being pumped, helps the driver to turn the steering wheel.
The principle of operation of power steering
The spool rotates relative to its body by twisting the torsion shaft. This action creates elasticity, steering responsiveness without which driving would become unpredictable and not very comfortable. The angle of rotation of the spool directly depends on the forces applied to the steering wheel - the more forces, the greater the angle of rotation, which means more oil passing through the distributor.
I hope that now you understand the importance of the quality of the oil in the power steering system of the VAZ 2112 and the fact that timely maintenance of the above devices is urgent. Next, we offer you instructions on how to change the oil in the hydraulic power steering system of your car with your own hands.
At the beginning of 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 does not represent anything complicated and does not take much of your time. So:
- We hang the front of the car, not forgetting to substitute reliable stops under the thresholds;
Attention! Also, do not forget to put anti-rollback devices under the rear wheels of the car and put it on the parking brake.
- Using a syringe and an extension cord put on it, we pump out all the liquid from the tank;
Draining hydraulic fluid from the reservoir
Advice! After the liquid in the tank has run out, 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, pour the hydraulic fluid into the tank to the maximum level and start pumping 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 final "touch" is the bleeding of the system, that is, removing air from it, for which, on a muffled car, we turn 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 a new one. This method is considered more effective, since it allows you to completely get rid of the residues of used oil, although it will be needed twice as much. The essence of this method is as follows:
- We pump out liquid from the tank "according to the old scheme";
- We remove the return hose from the tank and "muffle" the released fitting;
- The very same "return" hose is taken to the side, under the bottom of the car into a previously prepared container, having previously extended it with an additional hose;
- Pour 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 capturing air by 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 mark.
After changing the oil in the power steering of the VAZ 2112, pay attention to how much easier it became to rotate the steering wheel, and how much "softer" the power 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.

Power steering Priora oil change - Community "VAZ: Repair and Modification" on DRIVE2
So I decided to replace the oil in the power steering, for 5 years of operation it became completely black.
To begin with, you need to raise in 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 oil from the tank, I bought a 20-ku syringe 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 start pumping oil into any convenient container 
After the oil in the tank has run out, 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 the first time, I did it according to the instructions Then I disconnected the return hose, took a smaller bottle, cut a hole in it and directed 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 has been pumped out and what color it is. 
We connect the hose back to the tank, I immediately changed the clamp, because the old one has ceased to drag on. It seems worth 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 hose of a new sample, 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 your friend 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. Turn off the engine and turn the steering wheel again by making 5-7 full revolutions and watching as in air bubbles appear in the barrel, expelled from the system. Add oil if necessary to the desired level and enjoy the work done. 
You can also rinse the tank, because the filter is probably dirty there, but I'll do it next time.

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 steering gear ratio, which improves the maneuverability of the car.
- When driving on a country road, the hand bumps will be less. If the front wheel bursts while driving, control of the machine remains.
- If the device fails, driving is possible.
An oil change in a gur with a VAZ 2110 is carried out when an oil leaks or expires in accordance with technical maintenance, which is 60,000 kilometers of a car's mileage 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 order for a long time.
Power steering design
The main units of the device:
Steering device
- Booster pump and liquid container. The pump is driven by the engine crankshaft via a drive belt.
- Steering gear. It consists of a hydraulic cylinder and a spool-type control unit located in one housing.
- The devices are combined with high and low pressure pipelines.
The work of the hydraulic booster is as follows:
- When the torsion shaft is twisted relative to its body, the spool rotates. This creates a resilience that responds to the steering and makes it more comfortable.
- The angle of rotation of the spool depends on the force applied to the steering wheel. Increasing the steering force increases the steering angle, which allows more oil to pass through the assembly distributor. The better the lubricating fluid, the more reliable the operation of the unit.
Hydraulic booster oil change
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 is changed with mineral oil. Existing synthetic oils have a bad effect on the durability of rubber parts made on the basis of natural rubber due to their chemical aggressiveness. Synthetic oils can be poured into the power steering system if its parts are made of a special rubber composition, which is designed for synthetic oils.
Changing the gur VAZ 2112 oil 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 lifted so that they are both in the air.
Advice: For the stability of the car, it is necessary to substitute reliable stops under its rear wheels and fix the car with a hand brake.
- 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 fluid out of the reservoir
Tip: When pumping out the fluid, when it is not in the tank, it is necessary to turn the steering wheel to the left, this will squeeze the oil into the tank from the working cylinder, then to the right. Such actions must be repeated until liquid ceases to appear in the tank.
- New oil is poured into the reservoir up to the maximum level. The steering wheel is scrolled all the way to the right and left. Add the correct amount of oil as needed.
- The VAZ engine starts up, and the steering wheel turns are repeated.
- Changing the gur oil to a VAZ 2112 ends with pumping the system, which removes air from it. The operation is performed by scrolling the steering wheel 10 times from lock to lock in each direction.
The hydraulic fluid can be replaced by displacing the old oil with new one. This method is more effective, it allows you to completely get rid of the residues of the previously used oil, but you will need almost twice as much liquid, which increases the cost of work. In this case:
- A container for draining the used oil is installed under the bottom of the car.
- 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 attachment is muffled.
- The hose, previously 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 the container for the return supply 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 tank, which could cause the pump to catch air.
- A return hose is put on the tank fitting, the hydraulic fluid level is brought to the desired mark.
How the oil change in the VAZ 2112 power steering is carried out is clearly visible in the video. After a properly carried out oil change in the power steering system, the steering wheel will turn much easier, the amplifier pump will work "softer".
Power steering vaz
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 the operation of the 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 needs to 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 GRU is out of order.
Breakage signs
Oil in the power steering vaz 2110
Most often, the following signs indicate that the hydraulic booster is not working properly:
- When the steering wheel rotates, incomprehensible sounds are emitted that were not there before;
- The steering wheel turns more slowly than before. In addition, the driver has to exert more force when turning it 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 him.
Power steering oil vaz 2110
In order for the machine to always function normally and there were no failures during its operation, it is necessary that the driver maintains it in a timely manner. Moreover, such service must be correct. The power steering is driven by oil, so it is very sensitive to the state of such a fluid. There are some tips for maintaining it:
- The oil should be changed at least once a year. Especially often it is necessary to change the oil for those who use their car too intensively.
Note: otherwise the hydraulic booster will stop working correctly, so it will need to be repaired or even replaced, which will cost much more than buying a new oil.
- In addition, in addition to a complete oil change, it is sometimes necessary to top up it. Very often the oil level falls below the required level. Therefore, it must be topped up to the maximum mark. It turns black with frequent topping up. This indicates the need to replace it.
Operating rules
Power steering oil for vaz 2110
In order for the hydraulic booster to serve for a long time, the following rules must be observed during its operation:
- In winter, it needs to be warmed up, otherwise it may crack under the influence of severe frost. 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 under no circumstances should you drive the car.
Note: This will lead to an emergency on the road, as the driver may not be able to turn off in time.
- If the oil level in the hydraulic booster is below normal or it is not there at all, then the use of the machine in this case is prohibited.
- You should not keep the steering wheel in its most extreme positions for too long. This overloads the pump.
Note: You do not need to hold the handlebars in extreme positions so that the load is not so strong. It is enough to take it back just a few cm.
How to choose oil for power steering
Power steering oil vaz 2110
Usually, for any model, the manufacturer gives recommendations on what kind of oil should be added to the power steering. 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 a sufficient amount of those protective properties that the GRU needs.
Note: in some cases it is necessary to fill this system with regular engine oil. But this should be done only in emergency situations.
How to understand that the hydraulic booster needs to be replaced
It is only necessary to start replacing the GRU system if:
- There is an oil leak in the system;
- The steering wheel turns much harder than it used to be;
- The oil developed a smell like burning;
- At higher rpm, 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 does not change in time.
Which oils to choose: mineral or synthetic
There are different types of 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). It is possible to fill such oils into this system only 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 actions in the exact sequence:
- Unscrew the tank cap where the oil is located.
- Draw off any fluid present here. For this, you can use a syringe with a thin tube.
- Fill in new fluid to the highest possible level.
- Start the engine and turn the steering wheel to the left and right several 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:
- Pump out liquid from the reservoir.
- Loosen the clamps on the hoses that go to the reservoir.
- Remove hoses and reservoir. It needs to be rinsed.
- The hose from the steering rack should be put into a plastic bottle at one end.
- Switch on the engine. Turn the steering wheel left and right. This will allow excess fluid to flow out of the system, which will flow out through the hose.
Note: Before starting work, you can hang out the front of the machine to make it easier to turn the steering wheel.
- The second hose should be inserted into the funnel. Pour new liquid through it.
- You need to collect everything the other way around.
You can also 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 independently replace the power steering fluid on a VAZ car
If you find oil drips in the area of the power steering, then most likely the source of the oil leak is the power steering system pipes. Check normal hoses, high pressure hoses and replace if necessary.
Before proceeding with the independent replacement of the fluid in the power steering (GUR) of your VAZ, familiarize yourself with the manufacturer's information on the types and brands of fluid used in the car. Most models use Pentosin Hydraulic Fluid CHF 11S VW52137.
I would like to note that the procedure for changing the fluid in the power steering is not complicated 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 sills.
Then, using a syringe with an extension in the form of a plastic tube, we pump out the waste 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 appeared liquid again.
We carry out this procedure until the liquid in the power steering tank runs out
Next, we remove the hose that comes from the passenger compartment and enters the tank (shown by the short arrow in the figure), and then turn the steering wheel from side to side, a certain amount of oil should come out. Then we turn the steering wheel several times 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 the hydraulic system with new oil. In this case, let's take the oil for power steering Castrol ATF Dex II Multivehicle. We need about 800 grams.
Pour liquid into the tank to the maximum level and begin to turn the steering wheel all the way, first to the left and then to the right.
Now we start the engine for a while and turn it off. Then we turn the wheel again. At the input of these operations, the liquid in the tank will decrease, do not forget to add it.
At the end, we perform pumping and air removal from the power steering. To do this, turn the steering wheel on a muffled car 10 times in each direction. Then the same amount with the engine running.
After replacing 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 lies in the displacement of old oil with new one. This method is of higher quality, since it is possible to completely get rid of the old oil, but at the same time, you will need twice as much new oil.
For this procedure, you will need an assistant 1. We pump out the fluid from the power steering tank; 2. Remove the return hose from the tank and muffle it, for example, with another hose with a pinched end; 3. On the return line we put on another hose and bring it under the car into a previously prepared container; 4. Fill the tank with liquid to the maximum level, the assistant starts the engine; 5. As soon as the liquid is gone, the assistant turns off the engine at your signal; 6. Fill the liquid again up to the “MAX” mark and repeat the procedure until the clean liquid flows into the prepared container;
7. Put on the return hose back and add power steering fluid to the desired level.
And in conclusion, we suggest that you familiarize yourself with the procedure for replacing the power steering hoses on a VAZ car

Oil change in power steering on 21124 [Archive] - AvtoSaratov
View Full Version: Power Steering Oil Change 21124
The tube from the GUR began to sweat (photo below from the network) is not critical, but the eyes are corns. 167860167861167862 decided to change it, and at the same time power steering fluid
that is flooded with xs, but flooded from the factory. In the internet they write that only Pentosin CHF 11 should be poured, what was it who poured and how did it change?
He also sweats - scored, the level does not seem to fall. Filled with pentosin.
yes, the level also does not fall too much. Who has seen these hoses and oil on sale? what price they have) or maybe I'll score too)))
On sale, neither one nor the other did not see. The oil can be ordered either on the Internet or from BMW dealers - it is mainly used there in power steering.
In the internet they write that only Pentosin CHF 11 should be poured. Otherwise, what?
also a snotty hose, and for a long time already. does not greatly affect the level. I'm not going to change in the near future, if the leak does not progress, since the hoses are not cheap, it does not bother so far in general. for topping up I bought slurry for the power steering mannol in the Lada Market, which is on Shekhurdin, after asking what can be added from the engineer under warranty. after topping up everything is fine.
Otherwise what? well, as I understand it, pentosin is poured from the factory and it cannot be interfered with in the same way as engine oil, probably this oil is recommended by the power steering manufacturer (on boomers the same power steering and the same oil)
167932 full analogue of SCT MANNOL CHF, more affordable in price and in stock.
Well, as I understand it, pentosin is poured from the factory and it cannot be interfered with in the same way as engine oil, probably this oil is recommended by the power steering manufacturer (on boomers the same power steering and the same oil) to interfere and fill - these are two different things, no? and who said that the power steering is the same?
stirring and pouring are two different things, aren't they? and who said that the power steering is the same? Well, actually, I'm not an expert, and these questions are also interesting, for this I created a topic ... Power steering ZF that is on my VAZ, that on BMW ... I just know that this oil is recommended by this manufacturer of power steering, and it is poured from the factory ...
Power steering ZF that on my VAZ, that on BMW ... ZF- on half of all cars in the world. At the VAZ, by the way, only part of the system is ZF. Pump, for example.
ZF- on half of all cars in the world. At the VAZ, by the way, only part of the system is ZF. Pump, for example. as far as I understand it is ZF gidrach (http://www.tuningsvs.ru/product_1455.html). what they put on many foreign models I read. The conversation is not about where and what they put, but about what to pour where to get)
if you need CHF, then write in a personal, I have
looked for hoses, no where not. there is where under the order, but the price was not small ...
changed yesterday. I took the oil from Maria (http://www.autosaratov.ru/phorum/member.php?7318-Maria). took a liter of mannol, poured too much into the run. a little not enough for refilling) in general, it did not work out neatly; the protection was doused a little when removing the hoses from the barrel, the lower hose is the return line.

There is only a top hose. There is no bottom. Can I buy it separately? How much will it cost?
today I looked in the tank, the oil is clean, a normal replacement for the original

Fluid change in power steering - logbook 2007 Lada 2112 on DRIVE2
My first entry. I haven’t figured out yet what, how and where)) Forgive me generously)) There was liquid Pentosin, it is written that it is poured into Bentley, for my dvin it’s itself)) Acquired naturally earlier, or rather a long time ago. Hands still did not reach to make a replacement. What is flooded has already been worked out (IMHO), since the liquid had tar light and smelled a little burnt, these are the two factors when it should change. Its service life is long. And now, in order. Didn't jack. The liquid quickly left on the running machine. I turned the steering wheel a little on the spot. Respect to the club of dvinovodov))
The same sleeve. Diameter 10mm, in the atom store for rubles they sell))
vk.com/official_club2112
When replacing, I did not disconnect the wiring with hoses from the absorber, everything was in place
This is what was in the tank itself. I poured it out without a syringe. There was a piece of hose a meter long and a little over 10 mm in diameter. He put one end in the tank, the other let go into an empty, unnecessary canister from the store water. Then, covering the free space in the filler neck of the tank around the hose with your fingers, made a small access between them and ... inhaling there a couple of times from the heart - all the slurry ended up in this jar)))
Then, he drained the rest of the slurry with small pieces of rags, having poured well there with a screwdriver))
The same pentosin. I took the Zhelezyak in Captivity, which is in the capital last year. A canister for a ruble. Expensive.
Connection: the lower hose is the return to the tank. I connected it with a 10mm sleeve with about the same hose, the end of it in an empty container for dumping dirt)))
A piece of hose, about 20 cm long, instead of a plug from the return line, I connected it with a free clamp and just put it just above the level of the tank. New liquid will not spill anywhere
When he poured in and did everything naturally, overlapping with rags. After removing the hose, part of the slurry still gets on the iron. Gram 50 was on the floor. But nothing got on the generator drive and on the belt. Everything is dry. Protect yourself))
I washed it well, it took one and a half liters of this wonderful liquid. Half a liter will always come in handy for refilling from smudges. If there are any)
Ride immediately after replacement. The liquid is clean. No buzzing, no itching, no noise
Liquid from the dipstick, after replacement and a short ride
