What oil to fill in the power steering What oil to fill in the power steering. What is poured into the power steering? Power hydraulic fluid

The hydraulic booster of the steering mechanism is used for comfortable control of the vehicle due to the free rotation of the steering wheel. This effect is achieved through the use of lubricating fluid inside the mechanism. Therefore, it is so important to use a high-quality lubricant that will adequately perform the functions assigned to it.

Use ordinary oil, which is strictly prohibited. The system will not work properly and there will be problems with the mechanism. But transmission lubricant can be used. It is important for every driver to know what oil should be used in the system and how to properly fill it into the power steering.

The main functions and characteristics of oils for power steering

The lubricating fluid in the power steering performs a number of important functions:

  • transferring thermal energy to cool the device;
  • corrosion protection;
  • lubrication of internal components and mechanisms;
  • distribution of pressure and gain between the working elements of the system.

Classification of hydraulic fluids power steering

The oil used in the power steering is its working fluid. This fluid falls into two broad categories:

  1. The mineral-based product does not attack the rubber rings that perform the sealing function. This lubricant provides additional protection for the material, due to which it does not crack when exposed to low temperatures. too viscous, especially in winter period, has a small resource and foams.
  2. Synthetic grease has a negative effect on the condition of rubber parts, only if they are not made of a special material. This oil is more expensive, but it can last longer. Its viscosity is uniform and this indicator does not change from the ambient temperature.
  3. Semi-synthetic products are characterized by an average cost, a long resource, which is an order of magnitude higher compared to mineral oils. Such greases exhibit high resistance to corrosion development and a less pronounced tendency to foam. Semi-synthetics cope with their direct duties perfectly. The only drawback of such a lubricant is the aggressive effect on the rubber elements.

Based on this information, you can easily determine which oil to fill in the power steering so that its operation is stable and the parts do not experience excessive stress.

Liquid composition

We figured out the base that is used to create a lubricant for power steering. But oils have a complex, multicomponent composition in which each component plays its role. In addition to the basic base, the composition of the lubricating fluid includes additives that also determine some of the properties of the material. And it doesn’t matter which lubricant is chosen: synthetic, semi-synthetic or mineral water. In any case, additives will be present in the composition of the lubricant, due to which the following characteristics may be characteristic of the product:

  • and formation of foam;
  • inhibitors of corrosion and oxidation processes;
  • increased anti-friction and anti-seize features;
  • providing color;
  • protection for rubber parts.

The hydraulic properties of the lubricant come down to resistance to foaming processes and setting the maximum operating temperature. The essence of mechanical characteristics is reduced to the compressibility index. The system maintains low pressure, therefore this indicator does not play a key role.

Viscosity is an important indicator for oil that is poured into the power steering. At low temperatures, the lubricant becomes thick and its properties are reduced, because the parts work "dry". As the operating temperature rises, the lubricant thins out.

Power steering oil color

Gradation according to the colors of the lubricant, which is used by many manufacturers, is very popular. The first lubricants were produced only in red, the designation PSF was used. Now there are several color options that are used to indicate different types of lubricants:


Among automakers, there are many who use the same oil for the automatic gearbox and power steering. This includes Japanese companies. Among European manufacturers, there is a different trend - they require the use of a special lubricant in the power steering.

In some cases, it becomes necessary to mix different fluids, for example, when you need to add lubricant, and not change it completely. This option is possible, but with some amendments. It is strictly forbidden to mix oils with different bases. For example, synthetics and mineral water cannot be mixed.

Yellow liquids and red ones are considered compatible, since their compositions are similar and such a combination will not harm the mechanism. True, you can’t ride on such oil for a long time. This decision is purely temporary. Green grease cannot be added to red and yellow liquids, because they have completely different bases.

How many liters will be required

The hydraulic power steering holds about a liter of grease when it comes to passenger cars. For trucks, up to 5 liters will be required. During the selection and purchase of oil, this feature must be taken into account. A small amount of lubricant must be added to the required amount. It may come in handy for the next topping up. We found out how much oil is needed for the power steering, now we need to figure out the replacement and topping up technology.

How to change the oil in the power steering

There are two methods for performing this repair. One of them assumes complete, the essence of the second is the partial addition of oil to the existing one. Changing the power steering oil will require the use of a number of tools and materials. It is recommended to prepare all this in advance so that nothing distracts you from the main process when doing the work. Everything you need to prepare, we have collected in the list:

  • new grease, the type of which corresponds to the manual of the car;
  • a 50 ml syringe, with which it will be convenient to remove the old liquid from the mechanism;
  • a tube that will be put on a syringe for lengthening;
  • container for collecting used grease;
  • rags;
  • liquid for washing parts (gasoline, carburetor cleaner);
  • funnel;
  • to dismantle the clamps, it is convenient to use a screwdriver or tongs, which are specially designed for this work;
  • heads in a set.

Power steering oil must be recycled. It must not be drained into the sewer and poured onto the ground. If everything you need is prepared, then you can get to work. It will consist of the following steps:


If it is required to carry out partial replacement lubrication, proceed as follows:


Complete relubrication is more time consuming and more labor intensive. But almost all the liquid will be replaced with fresh. This work is carried out according to the following scheme:


In some cases, after all work, extrusion of liquid may be observed. This situation indicates the unsuitability of the filter, which will have to be changed. We do not recommend buying a used part. Fork out for a new filter, you definitely won’t regret such a decision.

During relubrication work, air may enter the system and must be removed. This work is carried out according to the following scheme:

  1. With the engine off, the steering wheel rotates several times in different directions. The ignition key is turned until the shaft is unlocked. You need to rotate the steering wheel until bubbles come out of the system.
  2. We check the lubricant level and, if necessary, bring it to the normal position.
  3. We start the engine and turn the steering wheel several times to the limit. We turn off the engine and remove the car from the lift / thresholds. Check the lubricant again.
  4. We start the engine, turn the steering wheel and control the formation of air bubbles.
  5. We turn the steering wheel to the limit and check for leaks at the main joints. If everything is fine, then the work can be considered completed.

The condition and level of oil in the power steering must be constantly monitored. It is forbidden to drive without this lubricant, as the car is damaged and the operation becomes dangerous. Carefully choose the oil to fill the system. Ideally, you need to choose the lubricant that the manufacturer recommends in the manual. When choosing a different oil, remember the miscible liquids and incompatible ones.

All power steering fluids differ from each other, not only in color, but also in their characteristics: oil composition, density, ductility, mechanical properties and other hydraulic indicators.

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 fluid in the power steering in time and fill in the best quality fluid there. For the operation of the power steering pump use two types of fluids- mineral or synthetic, in combination 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 far from all drivers comply with this requirement, we will try to compile a list of the 15 best power steering fluids that caused the most confidence and collected a lot of positive feedback.

Notice that such liquids are poured into the power steering:

  • conventional ATF, as in an automatic transmission;
  • Dexron (II - VI), the same as ATP liquid, only a different set of additives;
  • PSF (I-IV);
  • MultiHF.

Therefore, the TOP of the best power steering fluids will consist of similar categories, respectively.

Scheme of the auto power steering system

Types of fluids for power steering

The types of lubricants that can be used are divided 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 power steering components.

mineral water

The basis of this type of liquid is chemical elements that help prevent accelerated wear of rubberized parts. For passenger cars and SUVs, the use of mineral water is relevant. The use of this type of substance provides 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 MEKHANIK presented the results of a test of lubricants from different manufacturers and spoke about the features of choosing oil for power steering.

What is the difference between power steering fluids

All lubricants vary in color and performance.

Fluid color differences

Color differences:

  1. The red stuff is usually made by Dexron. This type of lubricant belongs to the category of high quality mineral consumables. In practice, they are widely used in Japanese-made cars. Under the Dexron brand, ATF lubricant is produced, which is intended for use in automatic gearboxes.
  2. Yellow grease is usually used in European-made cars. Brands that produce yellow lubricants, a lot of. Usually they are sold in the domestic market under the PSF marking, which is indicated after the manufacturer's name and brand name. The mineral base is used as a base in these substances. Fundamental differences yellow lubricants from different manufacturers do not, the difference usually lies in the addition of specific additives.
  3. Green oils can be either synthetic or mineral based. For example, the green hydraulic booster lubricant Pentosin contains a mineral base. But on sale you can find green oils produced under the auto brand. Such products usually have a narrow specification and are designed for use in certain models of machines. Own lubricants are produced by the brands General Motors, Peugeot, Citroen.

What to consider when mixing lubricants?

General tips for interchangeability and miscibility of various consumables:

  1. If it becomes necessary to mix oils, then add a substance with the type of base that was previously filled in. If it is synthetics, then topping up mineral water is not allowed.
  2. Do not add grease of a different color. This is not strictly prohibited, in extreme cases, mixing is allowed, for example, if a liquid leak occurs and it must be urgently added to the unit. As soon as possible, you will need to drain the mixed lubricant and fill the system with new oil.
  3. You cannot fill the power steering expansion tank with 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 lubricant was previously filled in, then it can be replaced with a yellow consumable with a similar base.

If necessary, simply add lubricant to the power steering system, it is recommended to achieve the maximum match of the compositions by brand and color.

When do you need to change the oil in the power steering?

The regulation for the replacement of consumable fluid is determined by the vehicle manufacturer. It is rare for a lubricant to be changed and added, but many experts advise performing this task when the car runs from 60 to 150 thousand kilometers.

New lubricant is poured or added to the system as it evaporates and the level drops. In fact, the process of topping up the consumable can be performed once every 1-2 years. But the need for a change may appear earlier if a precipitate appears in the lubricant or an unpleasant smell of burning comes from it.

DIY Power Steering Oil Change: 5 Easy Steps

How much fluid to fill depends on the volume of the hydraulic amplification system. You can do the replacement task yourself.

The Behind the Wheel channel showed the procedure for changing consumables in the power steering and spoke about the features of this task.

Step 1

To change the lubricant, you need to prepare vehicle to this process. At the initial stage, the car owner needs to raise the front of the car on a jack so that the wheels come off the ground. This is required for free rotation of the steering wheel with the engine off. After raising the front end, you can place supports under the car to ensure safety.

Step 2

At the next stage, the lid of the reservoir is unscrewed, into which the lubricant 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 to simplify the pumping procedure.

All remnants of the consumable are drained from the tank by turning off the nozzles connected to the tank one by one. After disconnecting the hoses, the steering wheel of the car must be turned 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 performing the task, it is necessary to monitor the level of lubrication. 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 again must be scrolled 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 lubricant must be added to the reservoir. These steps should be performed until the oil volume is normal.

Step 5

After completing the above steps, the car 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 completed. When the volume of lubricant is higher, it needs to be pumped out a little from the system using a syringe.

The 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 your 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;
  • bleed fluid through the power steering system while the vehicle is stationary.

The consequences of using low-quality lubricants

If a low-quality lubricant is added to the power steering, this can cause the following consequences:

  1. The fluid will lose its parameters when operating at elevated temperatures. During operation, the temperature of the lubricant can be increased up to 100 degrees. If the lubricant base is made up of low-quality additives, then the fluid will coagulate, as a result, the procedure for turning the steering wheel can be difficult. Excessively low-quality oils lead to breakdown of power steering mechanisms, in particular, the pumping device.
  2. When using poor-quality lubricants, vapors hazardous to human health can be released, which, when the temperature of the liquid rises, enter the interior of the car through the ventilation system.
  3. Rapid wear of power steering components can occur. Poor quality lubricants lead to the destruction of oil seals and sealing components of the hydraulic booster. As a result, leakage of the substance may occur.

User Aleksey Bogdanov showed the procedure for changing consumables using a car as an example Renault Logan.

The hydraulic booster system works according to a certain principle. If there are problems with the power steering, then experienced drivers first of all begin to check whether there is enough oil in the system. Lubrication may simply run out, or a leak has appeared in the system. In the first case, it is enough to add oil to the system, but the second situation will require repair work.

After the power steering is put in order, you can also think about what kind of oil to fill in the power steering. There are drivers who are not particularly worried about this and pour the first lubricant they find into the power steering. Such actions are fundamentally wrong, so I will talk about which lubricant is best suited for the system and how to choose it correctly.

Despite the fact that the system works a little differently than the engine, the oil performs almost the same functions. If we dwell on them in more detail, then it is worth highlighting the following opportunities:

  • lubricating;
  • protective;
  • anti-corrosion;
  • transport - provides energy transfer from the pump to the rail.

This list of functions is most typical for a modern power steering. Asian cars are much more practical. Due to the design features, it is possible to fill in such machines in the automatic transmission and in the power steering with the same oil.

Features of the choice of liquid by color

All working fluids can be divided into two groups - mineral and synthetic. Basically, mineral products with additives are used. Synthetics in power steering are poured very harmfully. This choice is due to the increased aggressiveness of the composition. Lubrication can lead to rapid destruction of the system.

The best option for using lubricant in power steering is the choice of the original composition. The automaker indicates in detail in the instructions in the vehicle which oil is better to fill in the power steering. An essential parameter when choosing a suitable product can be the color of the lubricant. According to the existing rule, only compositions of the same color are allowed to be mixed.

Sometimes you can combine red lubricants with yellow ones. For the most part, this principle always works, but in some cases it can be violated. For example, green compounds are produced both on a mineral and synthetic basis, and this indicates that it is absolutely impossible to combine such products. Consider the features of lubricants for power steering by color:

Grease color general description Features of the composition and use Popular brands
Red Developed by General Motors. It happens synthetic and mineral. Lubricants are often referred to as gear lubricants. The composition includes impurities for friction clutches.
  • mineral water - Dexron II and Dexron III;
  • synthetic - ATF.
Yellow The main manufacturer is Daimler AG. Used in power steering and hydraulic suspension. Basically, synthetics are poured. and .
Green There are mineral and synthetic. Available VAG and BMW. The composition contains various additives that provide reliable protection for GUR. Pentosin.

Apart from colors should also be taken into account Chemical properties oils. The basis of the product is important - mineral (obtained from petroleum fractions) or synthetic. (developed with the participation of polyhydric alcohols). Mineral water is half the price of synthetics, but synthetic substances can withstand temperatures from -40 to +15 degrees Celsius. Mineral products have a temperature range of only -40 - +90 degrees.

The main task of additives in oils for power steering

A special set of additives is added to each type of lubricant. These substances are designed to perform certain functions:

  • lubricate parts different type– metal, rubber, plastic;
  • reduce the level of friction between parts;
  • stabilize the degree of viscosity of the lubricant;
  • ensure protection of parts against corrosion;
  • does not allow lubricants to foam;
  • extend the life of components.

A very important point is that the additives color the lubricant in the desired color. Further, it allows drivers to choose the right product.

The most popular brands of lubricants for power steering

When there is no lubrication in the power steering system, it is better to fill in any substance. This will avoid subsequent system failure. Even an unsuitable composition will no longer be able to harm the rail seals, but it is important to immediately go to the service station to correct the violation.

When there is no suitable composition, it is best to use one of the most popular products:

  • Lukoil ATF Synth Multi Dextron III. A versatile product sold at an affordable price. Suitable for automatic transmission and power steering at the same time;
  • StatOil Pentosin LHM Plus. A quality product that was created specifically for Citroen. It tolerates temperature fluctuations;
  • 80W NEF PSF-3. Korean lubricant. The oil is inexpensive;
  • ATF SP III. Popular liquid in Russia. Has an excellent set of positive qualities. Suitable for Korean cars;
  • Hi Gear PSF. Fluid for power steering. The best option for Asian cars.

The lubricant in the hydraulic booster must be replaced every 30-45 thousand km. Lack of substance can lead to system failure.

Conclusion

The review can be concluded with the following conclusions:

  1. To avoid damage to the power steering, it is imperative to fill the system with lubricating fluid.
  2. At the initial stage, you need to choose a lubricant by color. It is not recommended to mix substances of different colors, because they can be of different composition.
  3. The best option is to use original or branded formulations that are recommended by manufacturers.

Accurate development of the mechanisms responsible for the maneuverability of the car is one of the main parameters of safe driving. It is important that all components and parts included in steering, worked flawlessly. A few years ago, the device of the steering system was simple and reliable, but after the massive introduction of hydraulic boosters, motorists have to take extra care of this element, which has a direct impact on driving. It is not so difficult to maintain the hydraulic booster in good condition - it is enough to fill it with high-quality oil when it is required. In this article, we will consider what kind of liquid to fill in the hydraulic booster, and also what are their differences, except for colors, cost and brands.

Frequency of oil change in power steering

The power steering fluid is not eternal and is not designed for the entire period of operation of the vehicle. 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 force on the steering wheel increases several times - the power steering fails. To prevent this situation, before the gap is eliminated, the oil must be topped up to a normal level. And here, motorists often have problems, because many do not know what kind of fluid is poured into the power steering.

Fluid function in power steering

Thanks to the power steering, it is very easy for the driver to turn the steering wheel. A special PSF fluid provides such conditions, 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.

Oil performs the following functions:

  • protects parts and components of the system from corrosion;
  • removes heat generated during the movement and friction of parts between themselves, preventing overheating.

How many functions PSF will perform, including how much it lathers, depends on the additives that are added to it.

Types of liquids

Often, drivers judge the quality of PSF fluid for power steering 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. Most commonly used for power steering mineral oil, due to the fact that rubber parts are present in its design. Over time, these parts dry out under heavy load on the steering system. Mineral based PSF extends the life of rubber parts.

Synthetic PSF is rarely poured for power steering. It can only be used for a vehicle control system if the manufacturer allows it. Often synthetics are used on technical machines who have permission to use it in their passport.

Each PSF power steering fluid 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 it is impossible to pour a solution of a different color. It is not recommended to mix mineral water and synthetics.

Substances of red color can have both mineral and synthetic bases. They are mainly used in automatic boxes gears. They are very rarely poured into the hydraulic booster. Red solution can be mixed with yellow, but only if they match in characteristics

Classification of oils for power steering by brand and color

Motorists can quite easily determine which liquid to fill in the power steering, since manufacturers have introduced the simplest color classification for PSF for greater convenience. Depending on the pigment added to the fluid, you can purchase red, yellow or green power steering oil.

Red and yellow ATF

Red oils are developed in compliance with the standards of the General Motors concern. They can be mineral or synthetic and are called Dexron. Today, Dexron III and Dexron IV are predominantly used. By the way, more often than in power steering, these fluids are used in automatic transmissions, therefore, in cars with an automatic transmission, one liquid 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 Dexron. The choice of fluid must necessarily be consistent with the recommendations of the manufacturers. These PSFs are widely used in cars of Kia, Nissan, Hyundai, Mazda, Toyota, etc.

Yellow liquids are produced under license from Daimler, they can also be mineral and 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 completely compatible. It is only necessary to follow that their chemical composition coincides - that is, you cannot mix “synthetics” with “mineral water”.

Necessary tools for self-changing oil

Power steering fluid is replaced using the following tools: Large syringe or rubber bulb. Socket wrench ten. Container (a plastic bottle will do). 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 last throughout the entire operation of the car. 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 perform its functions. Often, drivers wonder how to change the fluid in the power steering? You will need an assistant to complete this procedure. Replacing the fluid in the power steering is not particularly difficult, and every motorist is quite capable of carrying out this procedure on their own.

The procedure will be as follows: First of all, it is necessary to jack up the front of the car so that the front wheels are in the air, and also 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 with the engine turned off. Pre-protect belts and other engine parts from oil by covering them with rags. Open the tank cap. With a syringe with a flexible tube attached to it, remove the liquid from the tank to the filter. Using pliers, loosen the clamps on the 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 pipe (return) and place the free end in a pre-prepared plastic container.

In order for the liquid to flow out of the system, it is necessary to slowly turn the steering wheel to the left and right. This is how fluid is removed from the system. At the same time, you should not turn on the engine, because otherwise, although the process will go many times faster, air may enter the system. Now we move on to the suction hose that goes to the pump. It is necessary to 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: reinstall the tank and other elements. Before this, as necessary, it must be washed and checked for defects. Add liquid to the tank to the required level. Turn the steering wheel, then start the engine and turn it again. It is necessary to ensure that air bubbles disappear from the tank. After turning off the engine, lower the car and add fluid again to the MAX mark.

Partial replacement

This method is simpler, but less efficient. How to change the fluid in the power steering partially? We close 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. Remove the tank cap, suck out the liquid with a syringe (pear). Fill with new fluid to the correct level. We start the engine and then slowly turn the steering wheel in both directions until it stops. It is necessary to add oil again and repeat the procedure until the oil in the tank is clean. Thus, changing the oil is not a complicated procedure; it can be carried out without the help of specialists. The whole process will take no more than half an hour.
