Before starting self-study fluid change in the power steering (power steering) of your Vase, check the manufacturer's information on the types and brands of water used in the vehicle. Most models use Pentosin Hydraulic Fluid CHF 11S VW52137.
I would like to see what the procedure for replacing fluid in power steering not difficult 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 it out of the power steering reservoir
waste liquid. After the liquid is in the cistern will run out turn the steering wheel all the way to the left. Butter will appear in the tank again. We pump it out and turn the steering wheel all the way to the right. We pump out the liquid that appeared again.

Now let's start filling the hydraulic system with new oil. In this case, we take power steering oil 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 do pumping and removing air 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 fluid in power steering you should feel that the steering wheel has become much easier to turn
_
There is another way fluid replacement in 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.
You will need an assistant for this procedure.
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
How to replace power steering fluid on a VAZ car without the help of others

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 that you get acquainted in general terms 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 along 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 system bleeding, 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 remnants 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 - 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 in order to turn the wheels more easily and thereby expel the old oil from the system, I lifted it with 2 jacks. 
To pump oil out of 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 that it costs 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 and are 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.

Changing the oil in the VAZ gur makes it easier to rotate the steering wheel
- 1 Construction of the hydraulic booster
- 1.1 Changing the hydraulic booster oil
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 performed 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, base type, 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 under its rear wheels, you must substitute reliable stops 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 changed 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".
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
Most often, the following signs indicate that the hydraulic booster is not working properly:
- When rotating, incomprehensible sounds are emitted, which 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 service
In order for the car 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. works at the expense of oil, so it is very sensitive to the state of such a liquid.
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
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 level is below the norm 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
Usually, for any model, the manufacturer gives recommendations as to which one should 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 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, which will 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.
Hydraulic power steering (GUR).
There is an opinion that for many years of owning various kinds of cars, including imported ones, car owners are able to carry out many planned fluid changes on their own, without resorting to the services of service station specialists.
This is how it is, by and large, and it's not a secret for anyone that on the Internet today you can find a lot of useful and comprehensive information. However, one BUT remains unchanged - the lack of experience and qualifications of the car owner. And there is often so much information that finding the right solution sometimes becomes an unrealistic and impossible task.
How is it often that the fluid in the power steering is replaced by the car owners themselves in their garage? Yes, in fact, it is corny - the power steering fluid is bought, the return hose from the power steering tank is disconnected, the front wheels are hung on a jack (in order to reduce the load on the steering wheel when rotating), and the "happy car owner" starts turning the steering wheel left and right, trying this squeeze out the remaining liquid. Eventually, the fluid stops flowing out of the hose. Hurray, all the liquid has been drained. The return rod returns to its rightful place, fresh liquid is poured into the tank. We turned the steering wheel, added some more fluid. EVERYTHING, the replacement was successful, everything is clean and fine in the system. Moreover, in case of an unforeseen event, there is more than half a liter left in the glass. No matter how .........
I specially wrote the phrase "Happy car owner" in quotes. For there is no happiness in such a replacement. Few people know that about 1 liter of liquid is poured into the power steering. And with the replacement method described above, the old and often very dirty liquid will not come out completely, but only partially. Most of it will remain in the system and will simply mix with the new one. As a result, after a very short period of time, the car owner will be able to notice that the liquid darkened very quickly and again acquired a dirty tint. And the dirt becomes, first of all, the cause of malfunction and breakdown, and in the future, very expensive repairs.
Another equally common way to do the same procedure that I described above, but with the engine running. Allegedly, a working power steering pump will squeeze out the dirty liquid completely. All you have to do is pour fresh water and enjoy the comfort. Another delusion. As soon as you start the engine, the power steering pump will spit out liquid in a split second, while leaving the entire power steering system without lubrication and full of air. You simply will not have time to add fluid to the tank. And airing the power steering system, as a rule, leads to very quick breakdown. GUR OPERATION WITH NO LIQUID IS CATEGORALLY FORBIDDEN !!! IT IS FORBIDDEN TO CHANGE LIQUID IN THIS WAY !!!
Why else does the system of replacing fluids by the pour / fill method do not give the desired result? DIRT! During the period of operation, dust gets into various systems of the car in one way or another. Various deposits are formed that wander through the system. The fluid change described above does not provide any guarantee that these deposits will be removed from the system along with draining the old fluid.
I perfectly understand car owners, because I myself am that such fluid replacements are, first of all, SAVING money. Because, whatever one may say, but the car requires certain financial costs. Believe me, this is an imaginary sense of economy and only at first glance. Because the saved funds often lead to even greater costs - in case of failure of components and assemblies, in case of their breakdown. Don't skimp on your car. This will help you to avoid later many unpleasant moments and considerable repair costs.

What kind of oil to add to the power steering, vaz 2111 | Topic author: Vladislav
Nikolay, you have ZF written on the lid, then they fill in
Raisa I don't know how 2111, but the oil for the gearbox was poured into Lanos, the automatic castrol Veronica and Narmonek. I think the same here. but in general it should be written in the manual
Diana A liquid of the type: Pentosin CHF11S is poured into the power steering system of the VAZ 2110 - 2111, in the amount of 1.6-1.7 liters. During operation, topping up is carried out to the maximum level using the dipstick on the tank lid.
Ivan Look what color the liquid you have filled in. There are two possibilities. Either red, then Dexron, Gregory, or green, then Pavel Pentosin or an analogue.
What kind of oil to fill in the power steering? This question interests car owners in different cases (when changing fluid, when buying a car, before the cold season, and so on). Japanese manufacturers allow automatic transmission fluids (ATF) to be poured into the power steering system. And the European ones indicate that it is necessary to pour special fluids (PSF). Outwardly, they differ in color. According to this main and additional features, which we will consider below, it is just possible to decide what oil to fill in the power steering.
Types of fluids for power steering
Before answering the question of what kind of oil is in the hydraulic booster, it is necessary to decide on the existing types of these fluids. Historically, it so happened that motorists distinguish them only by color, although this is not entirely correct. After all, it is more technically competent to pay attention to the tolerances that power steering fluids have. In particular:
- viscosity;
- mechanical properties;
- hydraulic properties;
- chemical composition;
- temperature characteristics.
Therefore, when choosing, first of all, it is necessary to pay attention to the listed characteristics, and then to the color. In addition, the following oils are currently used in power steering:
- Mineral... Their use is due to the presence of a large number of rubber parts in the power steering system - O-rings, oil seals and others. In severe frosts and in extreme heat, rubber can crack and lose its performance properties. To prevent this from happening, they use mineral oils that best protect rubber products from the listed harmful factors.
- Synthetic... The problem with their use is that they contain rubber fibers that are harmful to the rubber sealing products in the system. However, modern automakers have begun to add silicone to rubber, which neutralizes the effect of synthetic fluids. Accordingly, the area of their use is constantly growing. When buying a car, be sure to read in the service book which oil to pour into the power steering. If there is no service book, call your authorized dealer. In any case, you need to know the clear tolerances for the use of synthetic oil.
Let's list the advantages and disadvantages of each of the mentioned types of oils. So to the benefits mineral oils refers to:
- gentle effect on rubber products of the system;
- low price.
Disadvantages of mineral oils:
- significant kinematic viscosity;
- high tendency to foam;
- short service life.
Advantages fully synthetic oils:
Differences in the color of different oils
- long service life;
- stable work in any temperature conditions;
- low viscosity;
- the highest lubricating, anticorrosive, antioxidant and foam suppressing properties.
Disadvantages of synthetic oils:
- aggressive impact on rubber parts of the power steering system;
- admission for use in a limited number of vehicles;
- high price.
In terms of common color gradation, automakers offer the following power steering fluids:
- Red... It is considered the most perfect because it is based on synthetic materials. Refers to Dexron, which represent a class of ATF - transmission fluids for "automatic" (Automatic Transmission Fluid). These oils are often used in automatic transmissions. However, they are not suitable for all vehicles.
- Yellow color... Such fluids can be used for automatic transmissions and for power steering. Usually they are made on the basis of mineral components. Their manufacturer is the German concern Daimler. Accordingly, these oils are used in machines manufactured by this concern.
- Green colour... This composition is also versatile. However, it can only be used with a manual transmission and as a power steering fluid. The oil can be made on the basis of mineral or synthetic components. Usually more viscous.
Many car manufacturers use the same oil for automatic transmission and power steering. In particular, these include companies from Japan. And European manufacturers require a special fluid to be used in hydraulic boosters. Many consider this to be a simple marketing ploy. Regardless of the type, all power steering fluids perform the same tasks. Let's consider them in more detail.
Functions of fluids for power steering
The functions of oils for power steering include:
- transfer of pressures and efforts between the working organs of the system;
- lubrication of units and mechanisms of power steering;
- anti-corrosion function;
- transfer of thermal energy for the purpose of cooling the system.
Hydraulic oils for power steering contain the following additives:
PSF fluid for power steering
- reducing friction;
- viscosity stabilizers;
- anticorrosive substances;
- acidity stabilizers;
- coloring compositions;
- antifoam additives;
- compounds for protecting rubber parts of the power steering mechanism.
ATF oils perform the same functions, but their differences are as follows:
- they contain additives that provide an increase in friction at rest of clutches, as well as a decrease in their wear;
- different fluid compositions are due to the fact that clutches are made from different materials.
Any power steering fluid is created on the basis of a base oil and a certain amount of additives. Due to their differences, the question often arises as to whether different types of oils can be mixed.
The answer to this question is simple - the fluid recommended by your car manufacturer. And it is unacceptable to conduct experiments here. The fact is that if you constantly use oil that is not suitable in composition for your power steering, then over time there is a high probability of complete failure of the power steering.
Therefore, when choosing which fluid to pour into the power steering, the following factors must be taken into account:
GM ATF Dexron III
- Car manufacturer recommendations. There is no need to engage in amateur performances and pour anything into the power steering system.
- Mixing is only permissible with similar compositions. However, it is undesirable to use such mixtures for a long time. At the earliest opportunity, replace the fluid with the one recommended by the manufacturer.
- The oil must be able to withstand significant temperatures. Indeed, in the summer, they can warm up to + 100 ° C and above.
- The liquid must be sufficiently fluid. Indeed, otherwise, there will be an excessive load on the pump, which will lead to its premature failure.
- The oil must have a significant resource of use. Usually, the replacement is carried out after 70 ... 80 thousand kilometers or every 2-3 years, whichever comes first.
Also, many car owners are interested in questions about whether it is possible to pour gear oil into the gur? Or motor oil? As for the second, it’s worth saying right away - no. But at the expense of the first - then they can be used, however, with certain reservations.
The two most common fluids are Dexron and Power Steering Fuel (PSF). Moreover, the first is more common. Currently, fluids that meet the Dexron II and Dexron III standards are mainly used. Both formulations were originally developed by General Motors. currently manufactured by numerous licensed manufacturers. Between themselves they differ in the temperature range of use. The German concern Daimler, which includes the world famous Mercedes-Benz, has developed its own power steering fluid, which has a yellow color. However, there are many companies in the world that produce such formulations under license.

Is it possible to mix fluids for power steering
What to do if you do not have the same brand of fluid that your car's power steering system uses? You can mix similar formulations, provided that they are of the same type ( "Synthetics" and "mineral water" should not be interfered in any way). In particular, yellow and red oils are compatible... Their compositions are similar, and they will not harm the power steering. However, it is not recommended to ride on such a mixture for a long time. Change the power steering fluid to the one recommended by your car manufacturer as soon as possible.
And here green oil cannot be added to red or yellow in no case. This is due to the fact that synthetic and mineral oils cannot be mixed with each other.
Liquids can be conditionally divided into three groups, within which it is permissible to mix them with each other. The first such group includes "conditionally miscible" mineral oils of light colors(red, yellow). The figure below shows samples of oils that can be mixed with each other if there is an equal sign opposite them. However, as practice shows, mixing oils, between which there is no equal sign, is also permissible, although undesirable.
The second group includes dark mineral oils(green), which can only be mixed with each other. Accordingly, they cannot be mixed with liquids from other groups.
The third group also includes synthetic oils, which can only be mixed with each other. However, it should be noted that such oils must be used in the power steering system only if this clearly stated in the manual for your car.
It is most often necessary to mix fluids when adding oil to the system. And this must be done when its level falls, including due to a leak. The signs described below will tell you about this.
Signs of power steering fluid leakage
There are several simple signs of a power steering fluid leak. By their appearance, you can judge that the time has come to change or top up it. And this action is associated with a choice. So, the signs of a leak include:
- lowering the liquid level in the expansion tank of the power steering system;
- the appearance of streaks on the steering rack, under rubber seals or on oil seals;
- the appearance of a knock in the steering rack when driving:
- more effort is needed to turn the steering wheel;
- the power steering pump began to emit extraneous noises;
- a significant backlash appeared in the steering wheel.
If at least one of the listed symptoms appears, it is necessary to check the fluid level in the reservoir. And if necessary, replace or top up it. However, before that, it is worth deciding which liquid to use for this.
It is impossible to operate the car without power steering fluid, since it is not only harmful to it, but also unsafe for you and the people and machines around you.
Outcomes
Thus, the answer to the question of which oil in the power steering is better to use will be information from the automaker of your car. Do not forget that you can mix red and yellow liquids, but they must be of the same type (synthetic only or mineral water only). Also add or completely change the oil in the power steering on time. For him, the situation is very harmful when there is not enough fluid in the system. And check the condition of the oil periodically. Do not let it blacken significantly.
