The power steering system is filled with liquid oil. The lubricant is filled into the power steering reservoir located in the engine compartment. To find the reservoir, we recommend using the service documentation for the machine. Many power steering systems use ATF transmission oil.

Types of fluids for power steering
The types of lubricants that can be used are classified into:
- synthetic;
- mineral.
Synthetics
In passenger cars, these options are practically not used; their addition is relevant in technical vehicles. The use of a synthetic type of fluid is permissible only if there are recommendations from the car manufacturer. It contains rubber fibers, which can cause damage to the components of the power steering.
Mineral water
The base of this type of fluid is made up of chemical elements that help prevent accelerated wear of rubberized parts. For cars and SUVs, the use of mineral water is relevant. The use of this type of substance ensures effective lubrication of all power steering elements and prevents the formation of rust.
Choosing a power steering fluid
When choosing a brand of power steering fluid, the following parameters are taken into account:
- characteristics of additives that are included in the lubricant base;
- hydraulic, chemical and mechanical parameters;
- viscosity value.
User Denis MECHANIK presented the test results of lubricants from different manufacturers and spoke about the features of choosing an oil for power steering.
What is the difference between hydraulic booster fluids?
All lubricants vary in color and performance.
Liquid color differences
Color Differences:
- The red substance is usually produced by the Dexron company. This type of grease belongs to the category of high quality mineral consumables. In practice, they are widely used in Japanese cars. Under the Dexron brand, ATF grease is produced, which is intended for use in automatic transmissions.
- Yellow grease is usually used in European-made cars. There are many brands that produce yellow lubricants. They are usually sold on the domestic market under the PSF label, which is indicated after the name of the manufacturer and the brand name. A mineral base is used as a base in these substances. There are no fundamental differences in yellow greases from different manufacturers, the difference usually consists in the addition of specific additives.
- Green oils can have both synthetic and mineral bases. For example, Pentosin Green Hydraulic Booster Lubricant contains a mineral base. But on sale you can find green oils produced under the auto brand. These products usually have narrow specifications and are designed for use on specific machine models. Own lubricants are produced by the brands General Motors, Peugeot, Citroen.
What to consider when mixing greases?
General advice regarding the interchangeability and miscibility of various consumables:
- If it becomes necessary to mix oils, then add a substance with the type of base that was poured in earlier. If it is synthetics, then it is not allowed to add mineral water.
- Do not add grease of any other color. This is not strictly prohibited, in extreme cases, mixing is allowed, for example, if a fluid leak has occurred and it must be urgently added to the unit. As soon as possible, you will need to drain the mixed grease and pour new oil into the system.
- You cannot fill the power steering expansion tank with a highly specialized oil that was developed for another car model.
If you plan to completely change the lubricant, then its replacement is allowed taking into account the base. If a green mineral-based grease was previously filled in, then it can be replaced with a yellow consumable with a similar base.
If you just need to add grease to the power steering system, it is recommended to achieve the maximum match of the formulations by brand and color.
When do you need to change the oil in the power steering?
The procedure for replacing the consumable fluid is determined by the car manufacturer. The lubricant is rarely changed and added, but many experts advise to perform this task when the car runs from 60 to 150 thousand kilometers.
New grease is poured into or added to the system as it evaporates and the level falls. In fact, the process of adding consumables can be performed once every 1-2 years. But the need for a change may appear earlier if a sediment appears in the lubricant or an unpleasant burning smell emanates from it.
Do-it-yourself power steering oil change: 5 easy steps
How much fluid to fill depends on the volume of the hydraulic booster system. You can complete the replacement task yourself.
Channel Behind the wheel showed the procedure for changing the consumable in the power steering and talked about the features of this task.
Step 1
To change the lubricant, the vehicle must be prepared for this process. At the initial stage, the car owner needs to raise the front of the car with a jack so that the wheels are off the ground. This is required for free rotation of the steering wheel when the engine is turned off. After the front has been raised, the vehicle can be supported underneath for safety reasons.
Step 2
The next step is to unscrew the lid of the reservoir into which the grease is poured. It is located in the engine compartment. A syringe (medical or construction) is taken, a tube is connected to it, with the help of this device, all the substance is pumped out of the system. It is advisable to use a larger syringe in order to simplify the pumping procedure.
All residues of the consumable are drained from the tank by alternately disconnecting the nozzles connected to the tank. After disconnecting the hoses, the steering wheel of the car must be twisted in different directions, this will speed up the procedure.
Step 3
After draining, the pipes are connected back. Fresh lubricant is poured into the expansion tank. The filling is carried out through the neck of the tank; when completing the task, it is necessary to monitor the level of lubricant. It is recommended to complete the filling procedure when the liquid level is between the Min and Max marks.
Step 4
Then the steering wheel must be turned again in different directions until it stops several times. This will ensure the pumping of the power steering system, the lubricant will be able to disperse through all its channels. When turning the steering wheel, the fluid level may drop, if this happens, then the grease must be added to the reservoir. These actions should be carried out until the oil volume is normal.
Step 5
After completing the steps described above, the machine is removed from the jack and a test drive is made. This must be done as the fluid level may drop while driving. In this case, it is added to the system. If the trip showed that the level of the substance is normal, then the change procedure is considered complete. When the amount of grease is higher, it needs to be pumped out of the system a little by means of a syringe.
Channel Made in the garage clearly demonstrated the procedure for changing the lubricant in the power steering system of a car.
Difficulties with self-replacement
To eliminate the occurrence of difficulties when changing the lubricant on his own, the consumer must:
- accurately identify the condition, as well as the volume of the filled substance in the power steering;
- determine the type of substance poured into the tank;
- it is important to completely pump out the entire volume of consumables so that the new oil does not mix with the used one;
- pump fluid through the power steering system while the vehicle is stationary.
Consequences of using poor quality grease
If a poor-quality lubricant is added to the power steering, this can cause the following consequences:
- The fluid will lose parameters when operating at elevated temperatures. During operation, the temperature of the lubricant can be increased up to 100 degrees. If the base of the grease is made up of low-quality additives, then the fluid will curdle, as a result, the steering procedure can be difficult. Excessively low-quality oils lead to breakdown of the power steering mechanisms, in particular, the pumping device.
- When using a low-quality lubricant, vapors hazardous to human health can be released, which, when the temperature of the liquid rises, through the ventilation system, enter the car interior.
- Rapid wear of power steering components can occur. Poor quality lubricants lead to the destruction of the oil seals and sealing components of the power steering. As a result, a substance leakage may occur.
Video "An example of a lubricant change in Renault Logan"
User Aleksey Bogdanov showed the procedure for changing a consumable using the example of a Renault Logan car.
Power steering (power steering, hydraulic booster) is an element of the steering mechanism that greatly facilitates driving by creating additional effort at the moment when the driver turns the steering wheel.
This mechanism is quite simple and reliable, the working fluid in it is power steering oil. Through the specified hydraulic booster fluid, the pressure and forces are transmitted to the working bodies of the system.

Power steering oil: what you need to know
As mentioned above, the power steering creates additional force, making the wheels much easier to turn, especially if the car is stationary or moving at low speed.
Power steering also allows you to soften shocks from road irregularities on the steering wheel, increase safety in the event of a tire rupture on the front wheel, etc. The power steering also provides the necessary feedback, a car with power steering is stable, it clearly follows a given trajectory.
It is important to understand that the most important element in this hydraulic system is the working fluid. In other words, power steering oil must have special properties as it performs a variety of functions and tasks.
- First of all, through the power steering fluid, force is transferred to individual elements of the steering mechanism;
- Also, the fluid in the power steering provides lubrication of units and mechanisms, protection against wear;
- Parallel power steering fluid prevents corrosion on system parts;
- You can also highlight the removal of excess heat through the power steering oil, that is, cooling;
The power steering fluid itself is based on a base oil (it can be mineral, semi-synthetic and synthetic), as well as a package of active additives. There are a large number of similar products on the market today, which at first glance may be similar, however, it is important to take into account their features and differences.
Moreover, the use of an unsuitable fluid can cause malfunctions, reduced service life, or complete failure of the power steering. In other words, you need to know what kind of oil to pour into the power steering and how to make the correct selection of fluid. Let's figure it out.
By the way, the automakers themselves separately recommend certain hydraulic oils for power steering. For example, fluids for power steering on Japanese and many Korean cars are usually suitable for. In other words, in this case, the oil in the power steering is the transmission oil for automatic gearboxes. However, European manufacturers recommend pouring special PSF fluids into the power steering for their cars.
Such fluids differ in color, have different specifications, tolerances and characteristics. Of course, many car owners have difficulties with what kind of oil to fill in the power steering. To get an answer to the question, you need to study the types of such liquids separately.
Types and types of oils in the hydraulic booster
So, the types of power steering fluids are often divided only by color. In fact, the oil in the power steering can be red, green, yellow (amber), etc. However, this is a common mistake. Even taking into account the fact that the liquid is the same color (for example, green), this or that product may have different tolerances.
As a rule, power steering fluids differ in viscosity, mechanical and hydraulic properties, in their chemical composition, in temperature characteristics, etc. Also, do not forget that the oils in the power steering can have a different oil base.
- Usually, mineral oils in power steering have the softest effect on rubber elements and seals, of which there are a lot in the power steering system. However, if the frosts are strong, the operational properties of the "mineral water" change, such a liquid thickens, it is pumped worse through the system, etc. In some cases, the seals can be squeezed out by too viscous power steering fluid. Also, mineral oil ages quickly and often requires replacement.
In short, the advantages include a mild effect on the rubber elements of the system and an affordable price. As for the disadvantages, there is a high kinematic viscosity, increased foaming and a short service life.
- Synthetic oils are more stable at both low and high temperatures, but they are more aggressive and can harm rubber seals. To solve the problem, silicone is added to the power steering oil seals themselves and other rubber elements, which increases the service life of the sealing elements.
It is important to understand that if the car is old, the decision to fill in more expensive synthetics can cause failure of the sealing elements, their cracking, swelling and leaks. Moreover, if the power steering is leaking, this can be a rather serious problem that requires urgent repair.
To summarize, the advantages of synthetic oils for power steering include a long service life, preservation of the declared properties in a wide temperature range, reduced viscosity, better lubricating and anti-corrosion properties, low foaming, etc. The disadvantages are considered to be an active negative impact on rubber parts and high cost.
We also add that you can also find semi-synthetics, which is an average variant for a number of indicators. The main advantage is a more stable viscosity at low and high temperatures compared to mineral oils, as well as a more affordable price compared to fully synthetic counterparts.
Coming back to color, power steering fluids are generally red, yellow and green in color.
- Red power steering fluid is usually synthetic, belongs to the Dexron group of oils (ATF fluids for automatic transmissions). Typically used in power steering and gearboxes in many American, Japanese and Korean cars (Opel, Chevrolet, etc.).
- Yellow fluids can also be poured into both automatic transmissions and power steering. However, such oils can be mineral-based and are often used for models of the Mercedes-Benz concern (MB).
- Green oil in the power steering, as a rule, is still poured into the manual transmission, it can be both synthetics and semi-synthetics, and mineral oil. Often, this product is slightly more viscous. Such fluids can be found in various automobiles of world concerns.
In practice, most manufacturers strive to make the oil universal so that it can be used both in automatic transmissions and in power steering and other hydraulic systems. This practice is widespread among American, Korean and Japanese manufacturers. However, European manufacturers often recommend pouring special fluids into the power steering.
In fact, both automatic transmission and power steering are hydraulic systems. All fluids in the power steering (regardless of color, properties, oil base, etc.) perform the same functions.
At the same time, the oil in the automatic gearbox is under heavy loads and is in difficult conditions. It turns out that if the fluid is capable of working normally in an automatic transmission, then if it is used in a power steering, where the conditions are much milder, problems should not arise.
It is for this reason that motorists believe that there is no need to use special oils and buy only the recommended power steering fluid. Also, the question often arises when and why it is necessary to change the oil in the power steering, as well as whether it is possible to mix the power steering oil. Let's take a closer look at these issues.
Signs of power steering malfunction
First of all, the oil in the power steering has a limited service life. As a rule, this is about 100 thousand km. mileage or 4-5 years. Also, the answer to the question of when to change the power steering fluid is considered to be characteristic signs indicating the need for replacement.
So, it is necessary to change the oil ahead of time in the event that there were problems with the power steering, the oil lost its properties, does not fit, adjusted for climatic conditions, the oil was topped up using a product different from the one that was filled earlier or recommended by the car manufacturer and etc.
As far as signs of power steering problems are concerned, the most serious problem is steering rack irregularities due to power steering fluid leaks. Please note that the oil level in the power steering should always be at the required mark, since a decrease in the fluid level in the power steering tank can lead to wear and malfunction of the mechanism.
The following signs can indicate leaks: the steering wheel turns hard, there is a change in the effort on the steering wheel (the steering wheel turns in jerks), etc. Also, the steering rack itself begins to knock when driving through irregularities, oil drips are visible, the power steering and the power steering pump make a lot of noise, a backlash is noticeable on the steering wheel, etc.
In this case, you should immediately check the fluid level in the reservoir and assess the condition of the oil. If the level has dropped, you need to add oil, and then go for diagnostics and repairs. Please note that you cannot continue driving with a faulty power steering, as there is a high risk of jamming the mechanism on the move, which can cause serious accidents!
If the level is normal, but the oil itself has turned black, shavings are visible in it, then you should start with a complete oil change in the hydraulic booster. The main thing is to choose the right replacement fluid.
What kind of oil to fill in the power steering
For reference, both ATF for automatic transmissions and PSF for power steering reduce friction, viscosity stabilizers, corrosion protection components, antioxidant additives, anti-foaming additives, and solutions for protecting rubber parts are included.
At the same time, ATF oils also have additives that prevent clutch slippage and also increase the service life of the friction discs. It is important to understand that in different automatic transmissions, clutches can be made of different materials, which is taken into account when developing oils for certain boxes.
It turns out whether such "additional" additives are needed in the power steering or not, remains a question. If the manufacturer allows them to be used in their mechanisms, then yes, you can safely pour ATF into the power steering.
If the manufacturer recommends a special liquid, it is better not to experiment. Again, a simple example. The owner of a Japanese car will say that you can pour the same oil both in the automatic transmission and in the power steering. And it turns out to be right. However, the point is not in the oil, but in the fact that the car manufacturer separately took into account such a feature.
If you repeat the same with models where you need to use only PSF fluids, ordinary ATF oil can damage the hydraulic booster. The reason is that the automatic transmission uses synthetic oil, while the power steering oil seals on a particular car can only be designed for a less aggressive mineral fluid (for example, yellow).
As a rule, if red oil is poured into the power steering instead of yellow or green, nothing will happen immediately to the amplifier, however, the service life of the unit may be noticeably reduced, oil leaks from the hydraulic booster through the oil seals and seals may appear much earlier than the due date, etc.
- Now let's move on to mixing. As a rule, mixing different products is strongly discouraged for both engine and transmission oils and other types of oils (including power steering).
On the other hand, if you urgently need to add oil to the power steering, you can use red ATF instead of green, etc. In this case, one should pay attention to a number of features.
First of all, one should look not at the color, brand and manufacturer of the oil, but at the type of fluid to be added. You can only mix similar compositions, provided that they are of the same type. Simply put, synthetics are mixed only with synthetics, mineral only with mineral or, in extreme cases, semi-synthetic. It is strictly forbidden to mix mineral oil with synthetic!
It turns out that even if you mix red and green synthetic oil, there should be no problems, since the compositions are similar. In any case, it is better to look for exactly the same oil or as similar as possible for topping up, and also not to drive for a long time on such a mixture.
This means that if the oils in the power steering are mixed, you need to replace the power steering fluid with the recommended one as soon as possible. Flushing may also be required before replacement. That is, you need to know how to flush the power steering. In a nutshell, flushing is best done with the same oil that is constantly used in the hydraulic booster.
Continuing to consider this topic, it should be added that for ease of selection of oil in the power steering, you can separately study the manual for the car or the table of compatibility of fluids for power steering by car brand (such a table is often found on specialized auto forums, etc.). You can also send a request to an authorized dealer of a particular brand.
As for the oils themselves and their compatibility, all fluids are divided into three groups:
- light mineral oils (red and yellow). They can often be mixed with each other for short-term use in the power steering system;
- dark mineral oils (often green in color), which can only be mixed within this group, avoiding mixing with products from other groups;
- synthetic oils, which, regardless of color, are conditionally compatible with each other;
We also add that today the most common two types of fluids for power steering: Dexron and PSF. Moreover, the first option has become much more widespread. In fact, fluids like Dexron II, Dexron III, etc. are the development of the GM company.
At the same time, you can buy both Dexron from GM, and equally high-quality analogues from other world manufacturers. As for PSF, the choice in this case is limited, since such fluids are often produced only by the car manufacturer itself, there are noticeably fewer third-party analogues.
Let's summarize
As you can see, choosing a power steering fluid for topping up or replacing may not be such an easy task. The fact is that you need to know in advance exactly which power steering fluid can be used in a particular system. However, having studied the above material, even novice motorists who service the car with their own hands or independently purchase technical fluids and consumables will not have any special problems.
We also note that in order to understand which oil is better to fill in the power steering, you must first carefully study the recommendations of the car manufacturer itself. It is optimal to use either the "original", which is filled from the factory, or such products that fully comply with all tolerances and recommendations.
Mixing oils is not recommended. If the situation is hopeless and you had to add another oil, the main thing is that the fluids are of the same type (synthetics + synthetics or mineral water + mineral water) and, preferably, of the same color (red + red). However, if the first rule cannot be ignored, if urgently needed, mixing different colors is still allowed (for example, red + yellow oil).
Finally, we note that the oil in the power steering must be periodically checked and immediately changed if necessary. During operation, the level must not be allowed to drop below the recommended mark, as well as blackening and contamination of the oil, loss of its properties, etc. Compliance with these recommendations will maximize the service life of the power steering, as well as avoid common problems with this unit.

What kind of oil to pour into the automatic transmission, what should be taken into account when choosing a transmission oil for an automatic transmission. Helpful hints and tips.
All power steering fluids differ from each other, not only in color, but also in their characteristics: oil composition, density, viscosity, mechanical properties and other hydraulic parameters.
Therefore, if you are worried about the long and stable operation of the hydraulic power steering of a car, you need to follow the operating rules, change the slurry in the power steering in time and fill it with the best high-quality liquid. For the operation of the power steering pump two types of fluids are used- mineral or synthetic, in conjunction with additives that play a major role in the operation of the hydraulic booster.
It is quite difficult to determine the best fluid for power steering, because, according to the manufacturer's recommendation, it is better to pour the prescribed brand into a particular car. And since not all drivers comply with this requirement, we will try to compile a list of the 15 best fluids for power steering, which caused the most confidence and received many positive reviews.
Note that such liquids are poured into the power steering:
- conventional ATF, as in an automatic transmission;
- Dexron (II - VI), the same as ATP fluid, only a different set of additives;
- PSF (I-IV);
- Multi HF.
Therefore, the TOP of the best hydraulic booster fluids will consist, respectively, of similar categories.
So, what is the best power steering fluid to choose from all on the market?

Accurate development of the mechanisms responsible for the vehicle's maneuverability is one of the main parameters of safe driving. It is important that all assemblies and parts included in the steering control work without failures. Several years ago, the steering system was simple and reliable, but after the massive introduction of hydraulic boosters, motorists have to take additional care of this element, which has a direct impact on driving. Maintaining the power steering is not so difficult - it is enough to fill it with high-quality oil when required. In this article, we will consider what kind of fluid to pour into the power steering, as well as what their differences are, in addition to colors, cost and brands.
Power steering oil change intervals
Power steering fluid is not eternal and is not designed for the entire period of vehicle operation. There are general recommendations for the frequency of replacement of the working fluid:
- with intensive use of the car - 1 time / year or after 30 thousand km;
- during normal operation and mileage up to 10 thousand km per year - 1 time / 2 years.
If there is a leak in the system and a significant decrease in the level in the tank, the liquid boils after a few minutes, and the effort on the steering wheel increases several times - the power steering fails. To prevent this situation, before eliminating the gap, the oil must be topped up to the normal level. And here motorists often have problems, since many have no idea what kind of fluid is poured into the power steering.
Power steering fluid function
Thanks to the power steering, it is very easy for the driver to turn the steering wheel. Such conditions are provided by a special fluid PSF, which transfers forces from the pump to the piston. The quality of its work will depend on what kind of liquid is poured into the control system and its level.
The oil has the following functions:
- protects parts and components of the system from corrosion;
- removes heat generated during movement and friction of parts with each other, preventing overheating.
How many functions PSF will perform, including how strongly it foams, depends on the additives that are added to it.
Types of liquids
Drivers often judge the quality of PSF power steering fluid by its color. Although color is an indicator, it does not determine its properties.
The main characteristics of the liquid:
- viscosity;
- how much it foams;
- hydraulic properties;
- mechanical qualities;
- Chemical properties.
It is by these characteristics that the quality of the oil can be determined.
There are two types of PSF fluids: mineral and synthetic. For the power steering, mineral oil is more often used, due to the fact that there are rubber parts in its design. Over time, these parts dry out under intense stress on the steering system. Mineral based PSF extends the life of rubber parts.
Synthetic PSF is rarely filled for power steering. It can only be used for the vehicle control system if approved by the manufacturer. Synthetics are often used on technical machines that have permission to use them in their passport.
Each PSF fluid for power steering has a specific color. It can be red, yellow and green. It is allowed to mix red and yellow liquids. If green oil is poured into the system, then a solution of a different color cannot be poured. It is not recommended to mix mineral water and synthetics.
Substances of red color can have both mineral and synthetic base. They are mainly used in automatic transmissions only. They are very rarely poured into the hydraulic booster. A red solution can be mixed with a yellow one, but only if they match in characteristics.
Classification of oils for power steering by brand and color
Motorists can quite easily determine which fluid to pour into the power steering, since the manufacturers, for greater convenience, introduced the simplest color classification for PSF. Depending on the pigment added to the fluid, you can purchase a red, yellow or green power steering oil.
Red and yellow ATF
The red oils are formulated to meet General Motors standards. They can be mineral or synthetic and are called Dexron. Dexron III and Dexron IV are predominantly used today. By the way, more often than in power steering, these fluids are used in automatic transmissions, therefore, in cars with an automatic transmission, one fluid is often poured into the transmission and into the power steering reservoir (usually in Korean and Japanese cars).
The main thing to remember is that Mineral-based Dexron cannot be mixed with Synthetic Dextron. The choice of fluid must be consistent with the recommendations of the manufacturers. These PSFs are widely used in cars of Kia, Nissan, Hyundai, Mazda, Toyota, etc.
The yellow fluids are licensed from Daimler and can be mineral or synthetic based. These substances are often poured into Mercedes-Benz vehicles.... They can also be used simultaneously in automatic transmissions. It is important that you can mix yellow liquids with red ones and vice versa, if necessary - they are fully compatible. It is only necessary to monitor so that their chemical composition coincides - that is, you cannot mix "synthetics" with "mineral water".
Necessary tools for self-oil change
Changing the fluid in the power steering is carried out using the following tools: Large syringe or rubber bulb. Socket wrench for ten. Container (a plastic bottle is suitable). Pliers. Flexible tube with a diameter of about 6 - 7 mm. Jack. Rags.
Complete replacement
According to some dealers, the oil in the power steering system should safely serve throughout the entire operation of the vehicle. But after all, it is a consumable material, which means that it undergoes aging in the process of its use and can no longer fully fulfill its functions. Often, drivers wonder how to change the fluid in the power steering? To carry out this procedure, you will need an assistant. Replacing the fluid in the power steering is not particularly difficult, and every motorist is quite capable of carrying out this procedure on his own.
The procedure will be as follows: First of all, it is necessary to raise the front of the car with a jack so that the front wheels are in the air, and also to install the supports. This is necessary so that the power steering pump does not experience excessive loads, as well as for free rotation of the wheels when the engine is off. Pre-protect belts and other engine parts from oil ingress by covering them with rags. Unscrew the tank cap. Using a syringe with a flexible tube attached to it, remove the liquid from the reservoir up to the filter. Using pliers, loosen the clamps on the branch pipes and unscrew the fastening bolts with a socket wrench. Disconnect the hoses from the tank, remove it and rinse if necessary. Next, remove the return tube (return) and place it with its free end in a previously prepared plastic container.
In order for the fluid to drain out of the system, it is necessary to slowly turn the steering wheel to the left and to the right. In this way, liquid is removed from the system. At the same time, it is not worth turning on the engine, since otherwise, although the process will go many times faster, air can enter the system. Now we move on to the suction hose that goes to the pump. Insert a funnel into the hose and pour fresh liquid through it. In this case, you need to turn the steering wheel until clean liquid comes out of the return line. After that, everything must be returned to its place: install the tank and other elements back. Before that, as necessary, it must be rinsed and checked for defects. Add liquid to the reservoir to the required level. Turn the steering wheel, then start the engine and turn it again. Make sure that air bubbles disappear from the tank. After you have stopped the engine, lower the car and add fluid again to the MAX mark.
Partial replacement
This method is simpler, but less efficient. How to partially change the power steering fluid? We cover the place under the tank with a rag to avoid getting oil on the parts. Similarly to the first method, we jack up the car. We remove the lid of the tank, suck out the liquid with a syringe (pear). Fill in new liquid to the desired level. We start the engine and then slowly turn the steering wheel in both directions until it stops. It is again necessary to add oil and repeat the procedure until the oil in the reservoir becomes clean. Thus, changing the oil is not a complicated procedure; it can be easily carried out without the help of specialists. The whole process will take no more than half an hour.
Keeping a car's power steering in working order is quite simple - you need to fill it with a specialized fluid of good quality. The main function of the power steering is to facilitate the process of controlling the machine. The mechanism cannot function properly without a special lubricating fluid, since the transmission oil must pass through all elements of the steering system. Power steering fluid is actually made on the basis of oils and a number of additional additives.
The main task of the oil in the steering gear is to efficiently transfer power from the pump to the piston. In addition, the liquid cools the rubbing elements well and prevents them from overheating. At the same time, the fluid protects system elements from corrosion and lubricates all major parts of the steering column.
