Do-it-yourself replacement of power steering fluid
The power steering, like all machine components, requires regular maintenance, including fluid replacement.
Where to start replacing power steering fluid
Power steering, like most car components, requires maintenance. If this is not carried out regularly, complex and expensive power steering repairs will be required. Many automakers do not regulate the period after which it is necessary to replace the fluid in the power steering.
Most people think that it only needs to be topped up regularly. But the fluid in the power steering still requires replacement, since intensive use of the car negatively affects it - it darkens and heats up. Sometimes there may even be a burning smell.
In this case, replacing the fluid in the power steering is required immediately.
To save money, you can perform the procedure for replacing the power steering fluid yourself. This procedure is not much more complicated than changing engine oil. To perform the operation you will need:
- Pre-purchased new fluid. You need to buy it strictly according to the recommendations of the car manufacturer. The liquid is needed in the quantity specified in the technical documentation of the vehicle.
- 20 gram syringe with tube. It is necessary for pumping out waste liquid.
- Container for old liquid. A 1.5 liter plastic bottle would be the best option.
Stages of replacing power steering fluid
Fluid replacement can be carried out in two ways - by complete or partial replacement. Partial fluid replacement is a simpler method, but is less effective.
To perform a partial fluid change, you need to unscrew the cap of the reservoir that contains the power steering fluid. Using a syringe with a tube, you need to completely pump out the liquid from the tank, and then fill in a new one up to the mark.
After this, you need to start the engine and turn the steering wheel, and then repeat the procedure until the desired result is achieved.
The second method, or complete fluid replacement, is a more labor-intensive procedure. In this case, you can achieve almost 100% results. The procedure must be performed step by step:
- You must first hang the front of the car so that the wheels are in the air. This will allow you to freely turn the steering wheel without starting the engine.
- Having unscrewed the lid of the tank, you need to pump out the liquid from the container using a syringe.
- On the hose clamps that fit to the tank, you need to loosen the bolts.
- Now you can disconnect the hoses from the tank and remove it. If necessary, it is better to rinse the tank.
- The hose running from the steering rack to the tank must be placed with the free end into a previously prepared container - a plastic bottle. In order for the liquid to start pouring out, you need to sit behind the wheel and vigorously rotate it in both directions. This will remove fluid from the system.
- As soon as the fluid stops flowing, you need to insert a funnel into the second hose (it goes to the power steering pump).
- The hose with the funnel must be secured and fresh liquid must be poured into it. The filling process must be alternated with active rotation of the steering wheel. You can make the process easier by asking someone to help you.
- You need to add liquid until a light stream flows from the hose inserted into the bottle. This means that the old fluid has been completely removed from the system.
- Now you need to put on the hoses and put the tank in place.
- You need to add fluid to the reservoir to the level and turn the steering wheel without starting the engine.
- It is necessary to start the engine and turn the steering wheel in both directions several times.
- After turning off the engine, you need to lower the car's wheels to the ground and add fluid to the level.
Having completed all the steps, you can qualitatively replace the fluid in the power steering and avoid its breakdown.

How to change the fluid in the power steering (power steering) with your own hands with a video, what oil to fill and how much
The steering system of modern passenger cars is equipped with a hydraulic booster - a device due to which rotation of the steering wheel does not require physical effort from the driver.
Despite the statements of many automakers that the power steering fluid must be replaced only if the device is repaired, the condition of the system should be closely monitored and contaminated technical fluid should be changed as necessary.
The power steering fluid performs several functions:
- it is the working fluid of the system,
- ensures its safe operation,
- protects device elements from overheating,
- corrosion and other damage,
- reduces wear on steering system parts.
The specially developed substance is designed to function in a wide temperature range - from –40 to +120°C.
Diagram of power steering on cars of the VAG concern (Volkswagen Aktiengesellschaft)
There are two key situations when it needs to be replaced:
- During repair of the power steering or after removing and installing the steering rack, the power steering fluid becomes contaminated with mechanical particles that can damage the system and cause a rapid loss of the fluid’s performance properties. In this case, it is necessary to completely replace the power steering fluid, even if the oil is relatively fresh.
- After a mileage of 20,000 km, it is recommended to regularly check the condition of the technical fluid in the power steering expansion tank. Using a probe, a small amount of the substance is placed on a clean, light surface - a napkin or paper. If the liquid is clear and retains its original color (red, green or yellow), then replacement is not necessary. The reasons for changing the fluid are mechanical contamination, cloudiness, and a burnt smell.
If the car's mileage does not exceed 20,000 km per year, replacing the power steering fluid is necessary approximately every two to three years. If this is not done in a timely manner, the contaminated synthetic substance loses its operational properties, which leads to overheating and damage to system elements, failure of the power steering, pump, and steering rack.
The hydraulic system uses a synthetic substance that must meet the following parameters:
- maximum operating temperature from 110°C;
- stable viscosity of the medium regardless of temperature and load level;
- the presence of additives to improve the efficiency of functioning under pressure;
- resistance to foaming;
- safety for the materials from which seals and hoses are made.
The choice of liquid is carried out in strict accordance with the manufacturer’s requirements
Today, manufacturers offer power steering fluids that vary:
- by type of base (synthetic and mineral);
- by viscosity;
- according to the characteristics of additives;
- by performance properties, etc.
On sale you can find power steering fluid in red, yellow and green colors, and red and green compositions are mineral and synthetic, and:
- red - only for cars with automatic transmission;
- yellow - universal, for “mechanics” and “automatic”;
- green - only for cars with manual transmission.
When choosing power steering fluid, you should follow the recommendations of the car manufacturer and use the same composition that is poured into the system, or its equivalent.
It often happens that liquids need to be purchased as a kit. One bottle flushes the system, the second remains in the power steering
Synthetic compounds may only be poured into the system for which they are specified by the vehicle manufacturer. The use of synthetics instead of mineral oil will lead to damage to the sealing elements and hoses, as a result of which the hydraulic booster will lose its seal and fail. Even pre-flushing the system will not get rid of this problem.
It is allowed to mix power steering fluids from different manufacturers with each other if they match in type (mineral with mineral, synthetic with synthetic), color and characteristics.
DIY partial replacement
A simplified replacement option is allowed only if the car owner knows exactly what type of composition is currently poured into the power steering reservoir and has the opportunity to use the appropriate composition. The reason for a partial replacement is contamination of the tank, stains or suspension on the surface of the fluid after a long period of non-use of the car.
Procedure:
- Unscrew the cap of the power steering reservoir, and using a 20-cc syringe + elastic tube, pump out the contaminated oil.
- Fill in new fluid, focusing on the upper mark, and put the plug in place.
It's better to pour through a straw than to splash precious liquid past
- Start the engine, turn the steering wheel right and left several times until it stops.
- Stop the engine and use a dipstick and white paper to check the level and condition of the fluid in the power steering reservoir.
- If necessary, repeat the procedure - the oil should eventually become clean.
How much fluid to pour into the power steering when completely filled?
Before proceeding with a complete replacement, you should find out not only the type of fluid, but also the required volume. If you did not find the information in the car manual, you can use an Internet search.
Eg:
- Toyota RAV4 D4D requires DEXRON II-D or DEXRON III fluid in a volume of 1.1 liters.
- for Renault Logan, Elf Elfmatic G3 fluid is used in a volume of 1 liter;
- Ford Focus 2 requires green liquid Ford WSA/M2C195/A or analogues, including Ravenol-PSF in a volume of 2 liters.
How to completely replace a Ford Focus 2
A complete replacement will be considered using the example of the Ford Focus II.
Tools for work
To completely replace the fluid in the power steering, for example, Ford Focus 2, you will need to use:
- a hose at least 1.5 meters long with a fitting at the end, its diameter must correspond to the return hose of the system;
- a hose of similar diameter about a meter long, equipped with a plug;
- containers with a volume of several liters and with wide edges or neck;
- pliers with curved tips; You can use regular round nose pliers, but they are less convenient
- jack;
- new power steering fluid (with a reserve, since flushing of the system is provided).
How to change: instructions
- Raise the car with a jack to make it easier to turn the steering wheel. The engine must be turned off.
- Unscrew the fasteners and remove the power steering reservoir.
Using pliers, move aside the clamp that secures the return hose (it comes from the steering rack). Drain the old fluid from the return hose into a substitute container. Install a hose with a fitting instead of the return line.
Instead of the second hose (direct supply), install a hose with a plug.
Hose location
- Then fill the reservoir with new fluid in a thin stream. One person should turn the steering wheel all the way in both directions, the second should monitor the quality of the discharged waste. Clean oil differs from contaminated oil in color and smell.
Rotate the steering wheel left and right until it stops several times
- After you are sure that the power steering is clean, install the standard hoses in place, secure the reservoir, and add new fluid to the top mark. To remove air locks, start the engine and smoothly rotate the steering wheel all the way in both directions - two or three repetitions are enough for the fluid to fill the entire system. Using the dipstick, check the fluid level and add if necessary.
- If the replacement is carried out correctly, the steering wheel will rotate smoothly and effortlessly. Once you are sure of this, screw in the cap of the power steering reservoir. Check the tightness of the hose connections.

Do-it-yourself power steering fluid replacement
Do-it-yourself power steering fluid replacement. Most modern cars are equipped with a hydraulic power steering system.
Like other units, the power steering mechanism requires periodic maintenance, although the vehicle’s operating instructions often lack information on this issue.
However, the amplifier's working fluid does not last forever; over time, it becomes unusable and therefore needs to be replaced.
Since manufacturers do not establish clear terms for power steering service, it is recommended to carry out the procedure in the following situations:
- when removing the steering rack;
- when repairing a pump or in the process of replacing leaking hoses;
- if the annual mileage of the car is no more than 20 thousand km, the oil is changed every 3 years;
- partial renewal of the fluid can be done immediately with an oil change in transmission units;
- when the liquid is contaminated visually.
Checking power steering oil
About choosing a liquid
Before you drain the power steering fluid and change it, you must purchase new fluid. Information about its quantity and name must be in the car’s operating instructions, in the section on refueling volumes.
When there is no such information, it is better not to experiment with mixing and purchase new oil for the full volume, after consulting with a specialist in advance.
Mineral and synthetic based hydraulic fluids are available for sale. For a hydraulic booster, it is better to take a mineral one; the color (red, green or yellow) does not matter. The main thing is to completely remove the old grease. The most famous and trusted manufacturers are Dexron and PSF.
Stages of replacing power steering fluid
To save money, you can perform the procedure for replacing the power steering fluid with your own hands. This operation is not much more difficult than changing engine oil. To perform the operation you will need:
New liquid purchased in advance.
20 gram syringe with tube. It is needed to pump out waste liquid....
Container for old liquid. A 1.5 liter plastic bottle will be the best option.

After this, you need to start the engine and turn the steering wheel, and then repeat the procedure until a suitable result is achieved….
Complete fluid change
- Raise the front of the car so that a pair of wheels are suspended and they can be easily turned by the steering wheel.
- Using the same 20 cm3 syringe, pump out the used lubricant from the power steering reservoir and loosen the clamps on the pipes connected to it.
- Remove the pipes from the fittings, dismantle the expansion tank and wash it thoroughly.
- Insert the hose disconnected from the lower fitting into a plastic bottle, start the engine and turn the steering wheel several times in different directions until it stops. The operation is performed with an assistant.
- When the oil drains into the bottle, turn off the engine, replace the tank and connect the pipes, clamping them with clamps.

How to change power steering oil
Each unit and mechanism of the car must sooner or later undergo appropriate maintenance. The power steering, which is equipped with most modern cars, is no exception.
Not all car manufacturers indicate rotation periods for standard fluids, however, this does not mean that they are eternal. After a certain period of intensive use, the oil darkens or acquires an unpleasant odor, which indicates an urgent need to replace it as soon as possible.
Power steering operation
The purpose of power steering is to increase comfort and facilitate vehicle control.
The resource and quality of operation of this system directly depends on its quality, condition and timely maintenance, as well as compliance with basic operating rules.
So, it is strongly not recommended:
- hold the steering wheel in the extreme position for a long time, leaving the engine at high speeds, since increased oil pressure will simply rupture the hydraulic cylinder seals and system hoses.
- press hard on the steering wheel while parking, if the side of the car wheel rests against the curb, the fuses of the electric pump will certainly “fly”.
- continue to drive with a leaky power steering that is leaking oil. In case of significant fluid loss, the pump breaks down within 10-15 minutes.
- use damaged boots, which allow microparticles of sand and moisture to penetrate into the hydraulic cylinder and mix with oil, accelerating wear of the mechanism.
- turn off the power steering in systems with a common drive of the generator, pump and pump, which can cause damage to the engine and/or electrical equipment.
If a malfunction is noticed, go to a service station. This will save you nerves, time and money.
Reasons for changing the oil
A short but very interesting video from which you will learn what power steering is and why you should change the oil in it.
As already mentioned, car manufacturers rarely provide specific information on when to change the oil in the power steering. Many drivers only check its level during fairly rare maintenance and, if necessary, top it up.
Auto mechanics take this issue much more seriously. They claim that power steering mechanisms are very sensitive to the quality and “freshness” of the composition used, and recommend its complete replacement every 25-30 thousand miles. With very intensive use, this is done at least once a year.
In addition to prevention, the procedure must be carried out if there is a radical change in color or cloudiness of the liquid (dark, earthy tint), as well as if a burning smell occurs. At the same time, the filters in the tank are changed along with the oil.
The use of fluids that have exhausted their service life and “usefulness” leads to intensive wear of system parts and failure of the power steering pump, steering rack and gearbox.
Do-it-yourself fluid replacement
The process of changing power steering oil involves draining the used composition, removing its residues from the system, washing the reservoir and filters, filling, pumping and topping up. All this is done at any service station in the shortest possible time.
If you decide to do the procedure yourself, then you will need:
- new oil in sufficient volume, which can be found in the documentation for the car;
- a large syringe and a container for the used composition (a plastic bottle will do).
From this video, you will learn how to change the power steering oil yourself.
The ideal replacement option is oil that is recommended for use by the vehicle manufacturer itself. If this option is not available, consult with specialists. In any case, buying cheap products can backfire, so you shouldn’t skimp.
Important! In critical situations, such as a significant fluid leak, the missing volume can be compensated by adding a compound for transmissions (automatic) or engine oil. But only for the short period of time necessary to get to the workshop and flush the system, otherwise the mixture of different oils will negatively affect functionality.
Step-by-step instruction
Changing the oil in the power steering can be done by complete or partial replacement. Partial change is simple, but the resulting effect is low:
- Having removed the cap of the power steering reservoir, we empty the container with a syringe and tube;
- Fill the purchased composition to the required level;
- We start the car and make movements with the steering wheel;
- We turn off the engine and repeat the whole process several times.
As a result, you determine the quality of the final composition in the system “by eye” and, if it satisfies you, complete the procedure. A complete update is more labor-intensive and time-consuming, however, it guarantees a result that is close to ideal:
- First of all, the car needs to be “hung out” so that you can easily rotate the steering wheel without starting the engine.
- Proceeding similarly to the first option, we pump out the used oil from the power steering reservoir.
- Next, loosen or remove the clamps, disconnect the hoses, dismantle the container (tank) and wash it.
- We direct the steering rack hose (“return”), which runs along the radiator cooler tube, into the bottle.
- By turning the steering wheel, we remove the remaining old oil from the system. Movements should be wide and quite intense.
- When the flow into the bottle dries up, insert a suitable funnel (watering can) into the second hose going to the power steering pump.
- Having secured the hose and filled it with the purchased liquid to capacity, we return to the salon and repeat the manipulations with the steering wheel.
- We add liquid to the hose with a funnel until new oil poured from the pump connection flows out of the “return” hole.
- After this, we put the tubes in place and securely fix them using standard clamps.
- We mount the power steering reservoir in its place and pour fluid into it to the specified level.
- We repeat the manipulations with the steering wheel, first with the steering wheel stalled, and then with the power unit running.
- We turn off the engine, lower the car to the ground and add oil in the tank to the desired level.
This is a simple way to change the fluid in your car's power steering. By deciding to do it yourself, you will save money and get to know your “iron horse” better. There shouldn't be any difficulties.
Advice from car enthusiasts
Sharing their experience with beginners, masters of their craft and experienced motorists advise doing all the work with a partner, since in the process you will definitely need “free hands”.
So:
- in point No. 5, if you start the engine at this time, the process will go much faster;
- at point No. 7, one turns the steering wheel, and the second holds the hose with a funnel and controls the situation;
- in point No. 8, your partner can monitor the oil level in the system while you add oil.
It is worth noting that in car dealerships this procedure is performed by experienced professionals who thoroughly wash the entire system with special means that are not always available to the average person, and upon completion, thoroughly pump and carefully check the power steering.
You, “for everything,” will need a few hours free from worries, as well as two to five liters of new oil.

Which power steering fluid to choose and how to replace it correctly with your own hands
The power steering system is filled with liquid oil. Lubricant is poured 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 gear oil.
Auto power steering system diagram
Types of power steering fluids
The types of lubricants that can be used are divided into:
- synthetic;
- mineral.
Synthetics
These options are practically not used in passenger cars; 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.
Mineralka
This type of liquid is based on chemical elements that help prevent accelerated wear of rubberized parts. For passenger cars and SUVs, it is important to use mineral water. The use of this type of substance ensures effective lubrication of all power steering elements and prevents the formation of rust.
Selecting 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 results of a test of lubricants from different manufacturers and talked about the features of choice.
What are the differences between power steering fluids?
All lubricants vary in color and performance parameters.
Liquid color differences
Differences in colors:
- The red stuff is usually produced 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. The Dexron brand produces ATF lubricant, 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 manufacturer's brand. These substances use a mineral base as a base. There are no fundamental differences in yellow greases from different manufacturers; the difference usually lies in the addition of specific additives.
- Green oils can be either synthetic or mineral based. For example, green lubricant for hydraulic booster 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 specific machine models. Own lubricants are produced by the brands General Motors, Peugeot, Citroen.
Red lubricant from the manufacturer Felix Yellow oil Pikhtin Green substance for power steering Febi
What to consider when mixing lubricants?
General tips regarding interchangeability and miscibility of various consumables:
- If there is a need to mix oils, then add a substance with the type of base that was poured earlier. If it is synthetic, then adding mineral water is not allowed.
- Adding lubricant of a different color is not allowed. This is not strictly prohibited; in extreme cases, mixing is permitted, for example, if there is a liquid leak and it must be urgently added to the unit. At the first opportunity, you will need to drain the mixed lubricant and fill the system with new oil.
- 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 replacing it is allowed taking into account the base. If a green mineral-based lubricant was previously filled in, 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 maximum consistency in composition by brand and color.
When should you change the power steering oil?
The regulations for replacing consumable fluid are determined by the vehicle manufacturer. The lubricant rarely needs to be changed or added, but many experts advise performing this task when the car's mileage ranges from 60 to 150 thousand kilometers.
New lubricant is poured into the system or added as it evaporates and the level drops. In fact, the process of topping up consumables can be performed once every 1-2 years. But the need for a change may appear earlier if sediment appears in the lubricant or an unpleasant burning smell emanates from it.
Do-it-yourself power steering oil change: 5 simple steps
How much fluid to fill depends on the volume of the hydraulic booster system. You can complete the replacement task yourself.
The Behind the Wheel channel showed the procedure for changing consumables in the power steering and talked about the features of performing this task.
Step 1
To change the lubricant, you need to prepare the vehicle for this process. At the initial stage, the car owner needs to lift the front of the car with a jack so that the wheels come off the ground. This must be done to allow the steering wheel to rotate freely when the engine is off. After raising the front end, you can place supports under the car to ensure safety.
Step 2
The next step is to unscrew the lid of the reservoir 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, and with the help of this device all the substance is pumped out of the system. It is advisable to use a larger volume syringe to simplify the pumping procedure.
All remaining consumables are drained from the tank by alternately disconnecting the pipes connected to the tank. After disconnecting the hoses, you need to turn the car's steering wheel 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. Filling is done through the neck of the tank; when performing the task, you need to monitor the lubricant level. 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 again be turned in different directions until it stops several times. This will ensure 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, lubricant must be added to the reservoir. These steps should be performed until the oil volume is normal.
Step 5
After completing the steps described above, the car is removed from the jack and a test drive is made. This must be done because the fluid level may drop during driving.
In this case, it is added to the system. If the trip shows 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 Made in a Garage channel clearly demonstrated the procedure for changing the lubricant in a car’s power steering system.
Difficulty with self-replacement
To avoid difficulties when changing the lubricant yourself, the consumer must:
- accurately identify the condition, as well as the volume of the substance poured into 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 oil;
- Perform bleeding while the vehicle is stationary.
Consequences of using low-quality lubricant
If a low-quality lubricant is added to the power steering, this can cause the following consequences:
- The liquid will lose its parameters when operating at elevated temperatures. During operation, the temperature of the lubricant can be increased to 100 degrees. If the lubricant base consists of low-quality additives, the liquid will coagulate, and as a result, the procedure for turning the steering wheel may cause difficulties. Excessively low-quality oils lead to breakdown of power steering mechanisms, in particular the pumping device.
- When using low-quality lubricant, vapors hazardous to human health can be released, which, when the temperature of the liquid increases, enters the vehicle interior through the ventilation system.
- Rapid wear of power steering components may occur. Low-quality lubricants lead to the destruction of oil seals and sealing components of the power steering. As a result, substance leakage may occur.

Power steering fluid: how to replace it yourself:
Mostly all modern cars have a mechanism such as power steering - power steering. At first it was created for use on heavy-duty vehicles in order to make it easier to control. Later, its use spread to all other cars, which, of course, became a definite plus in increasing the comfort and safety of driving.
The meaning of power steering in steering
First of all, a few words should be said about the importance of power steering. Its most important function, of course, is to facilitate steering control and, accordingly, reduce the effort when turning the steering wheel. By reducing the steering ratio, the number of steering revolutions is also reduced.
In addition, shocks when driving on poor road surfaces are softened and the feeling of the road is ensured.
When is it necessary to change the oil?
The power steering operates using oil, so it is important to monitor its condition. Manufacturers announce different periods for planned replacement: some claim that it will be enough to change the power steering fluid once every three years, while others talk about a period of one year. In this case, you must rely on the information given in the operating instructions.
Periodically you need to check the oil level, which must correspond to a certain volume indicated by the corresponding mark on the tank.
If the oil volume is below normal, then malfunctions begin to occur in the mechanism. This is expressed in the following: the steering wheel becomes harder to rotate, it becomes difficult to hold it in one position, and extraneous sounds are heard. In this case, it is necessary to add oil.
The timing of replacement is also affected by how active the vehicle is used. If the power steering fluid has darkened, changed color, or has a burning smell, this is a signal that it is time to replace it.
Which oil should you choose?
Power steering fluid is designated PSF. It comes in three colors: yellow, green and red. Previously, only red was released. It is similar to automatic transmission oil, but the difference lies in the presence of different additives.
It is prohibited to mix products with different compositions. So, green oil is not allowed to be mixed with others. Red can be combined with yellow. At the same time, it is recommended to fill in only one type of liquid to avoid the formation of lumps and clots.
Important condition: the fluid poured into the power steering must comply with the recommendations for a particular vehicle. Information about this is in the service book, but if you don’t have it on hand, you can contact the seller at an auto parts store. Using the VIN number, he can determine which oil is suitable in a particular case.
Synthetic oil can be added if the operating instructions allow this. Mostly mineral ones are used. Do not mix synthetic and mineral oils.
Red power steering fluid (Dexron family) is rarely used in power steering. It is mainly used for automatic transmissions. For example, Mercedes often use yellow oil. Peugeot cars have green power steering fluid. Ford, like other American cars, primarily uses red oil in the power steering system.
Necessary tools for changing oil yourself
Replacing the fluid in the power steering is carried out using the following tools:
- Large syringe or rubber bulb.
- Ten socket wrench.
- 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 last safely throughout the entire operation of the car. But it is a consumable material, which means it undergoes aging during its use and can no longer fully perform its functions.
Drivers often wonder how to change the fluid in the power steering? To perform this procedure, you will need an assistant. Replacing the fluid in the power steering is not particularly difficult, and every car enthusiast is quite capable of carrying out this procedure on his own.
The procedure will be as follows:
- First of all, you need to jack up the front of the car so that the front wheels are in the air, and also install 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 turned off.
- First protect belts and other engine parts from oil by covering them with a rag.
- Unscrew the tank cap.
- Using 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, if necessary, wash it.
- Next, remove the return tube (return) and place the free end in a pre-prepared plastic container. In order for the fluid to flow out of the system, you must slowly rotate the steering wheel left and right. This is how liquid is removed from the system. In this case, you should not turn on the engine, because otherwise, although the process will proceed 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 clear fluid comes out of the return line.
- After this, you need to return everything to its place: install the tank and other elements back. Before this, as necessary, it must be washed and checked for defects.
- Add fluid to the reservoir 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 again add fluid to the MAX mark.
Partial replacement
This method is simpler, but less effective. How to partially change the power steering fluid?
- Cover the area under the tank with a rag to prevent oil from getting on the parts.
- Similarly to the first method, we jack up the car.
- Remove the lid of the tank and use a syringe (bulb) to suck out the liquid.
- Fill in new fluid to the required level.
- We start the engine and then slowly turn the steering wheel in both directions until it stops.
- You need 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 done without the help of specialists. The whole process will take no more than half an hour.

Do-it-yourself power steering fluid replacement: step-by-step instructions
Drivers often believe that the power steering fluid does not need to be replaced, which is a very serious mistake.
Yes, if it is not expected that the car “travels” more than 100 thousand kilometers, then you don’t have to worry about such a component as power steering fluid.
But if the car is purchased “for years” and there is no desire to encounter problems with the operation of the hydraulic booster, you will need to pay attention to replacing the fluid in it.
In new cars, power steering is gradually losing competition to more modern electric power steering. However, it continues to be installed, including in many fairly modern car models, so it is important to know the rules for operating power steering and its main components.
The main components of power steering are: pump, distributor, reservoir, hoses, drive belt and hydraulic cylinder. The tank contains liquid, which can also be considered one of the main components of the system.
Please note: Recently, it has become increasingly rare to come across designs where the drive belt is a separate component of the power steering system. Nowadays, more and more often, the power steering pump is activated by one of the service belts of the outboard equipment.
Power steering fluid can easily last 100 thousand kilometers or more without replacement. In fact, its replacement is needed to reduce the load on the pump in the structure and avoid the need for its premature replacement.
Important: A hum during operation indicates wear of the power steering pump.
Before you start replacing the power steering fluid, you need to purchase it. There is a wide range of similar liquids in different price ranges.
You should not save when purchasing power steering fluid and it is better to give preference to trusted manufacturers, otherwise a cheap consumable component can lead not only to overheating of the system and failure of its components, but also to harm to passengers due to harmful fumes during operation.
The process of replacing power steering fluid is quite simple and does not require contacting a service center. You can do the work yourself, following the following plan:
- The first step is to remove the power steering reservoir cap;
- There is a filter under it - take it out. The easiest way to do this is to stick two fingers into the neck and then turn it, as if unscrewing it along a thread (in fact, the filter does not have any threads).
Next, we pull out the filter; Please note: Pulling out the filter, it becomes clear that the power steering requires fluid replacement from time to time. You will see that the entire filter is covered with plaque, dirt and sediment.
- After you take out the filter, take care of it.
Clean it, you can use a special cleaning spray for this;
- Next, we leave the filter to dry and move on to the process of removing the filled fluid from the power steering reservoir.
To remove liquid from the tank, you can use available tools - a large syringe or hose (remembering the methods used to drain gasoline from cars);
Please note: It is not recommended to drain fluid from the reservoir through hoses, as there is a risk that it will get on the box and other components of the car, after which it may get into the crankcase protection;
Important: Before removing the hose, be sure to place a container under the mounting points so that the remaining liquid gets into them.
Please note: This procedure itself can cause damage to the car, so it is not recommended to carry it out for long periods of time. It will take literally a minute to expel the remaining liquid, then turn off the engine.
Please note: On some cars there is little point in cleaning the reservoir. It is much easier to install a new tank if its cost is at an acceptable level.
Important: If there are traces of leaks on the hoses, it makes sense to replace them.
It is worth noting that the correct service method for replacing power steering fluid was discussed above, but there are also alternative methods. For example, there will be much less fuss if you use the displacement method.
To do this, just disconnect the power steering hose, direct it into a container and fill in fresh fluid until it displaces all the old accumulated fluid.
This method is uneconomical, and service centers prefer not to use it.
