Power steering system on a car Nissan Almera Classic Generation B10 is a critical component for safety and operating comfort. Many owners are faced with the problem of choosing the right fluid, since factory documentation does not always provide comprehensive answers, and oil specifications may change over time. The wrong choice of lubricant can lead to rapid wear of the pump, leaks in the steering rack and, as a result, loss of controllability at high speed.
Owners Nissan Almera Classic It is necessary to understand that the hydraulics of this model are sensitive to the type of fluid used. Using unsuitable analogues or mixing different types of oils often causes failure of expensive components. In this article, we will analyze in detail what characteristics the system requires, which brands have proven their effectiveness in practice, and how to correctly carry out the replacement procedure without involving service specialists.
Original specification and approvals
Manufacturing plant Nissan for model B10 recommends using fluid that meets the standard PSF (Power Steering Fluid). However, in practice, most mechanics and experienced drivers have come to the conclusion that transmission fluid works fine in the system ATF, developed for automatic transmissions. This is due to the fact that the power steering hydraulic pump has similar requirements for viscosity and anti-wear additives as the automatic transmission torque converter.
The most popular and proven option is liquid Dexron II or Dexron III. These oils have excellent low-temperature properties, which is critical for operation in harsh winter conditions, when the liquid thickens and creates increased load on the pump. Using the original marked canister Nissan Genuine Power Steering Fluid is also acceptable, but often it has a higher cost compared to high-quality analogues from leading lubricant manufacturers.
It is important to consider that the system Nissan Almera Classic not designed to work with modern synthetic fluids with aggressive additives that can corrode rubber seals. If you plan to switch from mineral oil to synthetic oil, you need to make sure that the oil seals and O-rings are compatible. It is strictly forbidden to mix red fluid (Dexron) with yellow or green (mineral oils for Mercedes or other brands), as this will lead to coagulation and failure of the entire hydraulic system.
β οΈ Attention! If you notice dark, almost black liquid with a burning smell on the dipstick or in the reservoir, this is a sure sign that the pump is working at the limit of its capabilities. In this case, a simple oil change will not help; diagnostics and, possibly, pump replacement will be required.
Analogues and proven brands
The automotive consumables market offers a huge selection of oils that can replace the original. The main condition is compliance with the viscosity characteristics and chemical composition. For Nissan Almera Classic products from brands such as Mobil, Castrol and Shell. These manufacturers guarantee stability of characteristics under temperature changes and absence of oxidation during long-term operation.
Among the specific names it is worth highlighting Mobil ATF 220 (Dexron II) and Castrol Transmax Dex II. They ensure smooth steering operation even in severe frosts. Also a popular choice is Shell Spirax S3 ATF. When purchasing, be sure to check the markings on the canister: there is a mark ATF Dexron II/III is a prerequisite for the safe operation of your vehicle.
- π΄ Mobil ATF 220 - a classic choice, optimal price-quality ratio for Nissan systems.
- π΄ Castrol Transmax Dex II β provides excellent wear protection and cleanliness of the hydraulic system.
- π΄ Shell Spirax S3 ATF - reliable oil with good thermal stability.
You should not skimp on the choice of fluid, since the cost of repairing a power steering pump or steering rack significantly exceeds the price of a high-quality canister of oil. Cheap counterfeits often do not have the necessary additive package, which leads to rapid wear of the pump bearing and noise when the steering wheel rotates. Always buy consumables from authorized distributors or trusted auto parts stores.

Symptoms of the need for replacement
The need to change the oil in the power steering can be determined by a number of external signs that become noticeable when operating the car. The first signal is a change in the sound of the pump. If when you turn the steering wheel you hear a characteristic squeal or buzz, this indicates that the liquid has lost its properties or air has appeared in the system. Also a sign of a problem may be a knocking or vibration transmitted to the steering wheel.
Another important indicator is the color and transparency of the liquid. In normal condition, the oil should be transparent, with a reddish or light brown tint (depending on the type). If you see that the liquid has become cloudy, dark, or has foreign particles (chips) in it, it is necessary to urgently replace it. The presence of metal shavings indicates that the pump or rack has already begun to deteriorate.
It is also worth paying attention to the force on the steering wheel. If the steering wheel becomes harder to rotate, especially at low speeds or at a standstill, this may indicate a loss of system tightness or a deterioration in the lubricating properties of the oil. In some cases, there may be a fluid leak under the car - in this case, changing the oil will not solve the problem; repair of the seals will be required.
β οΈ Attention! Don't ignore the pump noise. Working βdryβ or with degraded fluid can lead to pump jamming within just a few kilometers, which will entail an expensive replacement of the unit.
Preparatory work and tools
Before you start changing the power steering oil, Nissan Almera Classic, you need to prepare all the necessary tools and materials. The process does not require complex specialized equipment, but the presence of certain devices will greatly simplify the task. You will need new fluid (about 1-1.5 liters), a bulb to pump out the old fluid or a medical syringe with a tube, as well as a set of keys to remove the mudguard.
For comfortable access to the power steering reservoir, which is located in the engine compartment on the right (passenger side), it is often necessary to remove the plastic fender liner or engine mudguard. This is done in order to make room for maneuvers and to avoid spilling oil on hot engine parts. Also prepare clean rags and a container to drain the used fluid so as not to pollute the engine and the environment.
- π Set of keys β to remove the crankcase protection or fender liner (usually you need 10, 12 end pieces or a screwdriver).
- π Bulb or syringe - to pump out old fluid from the expansion tank.
- π New oil - a volume of at least 1 liter (it is better to take 1.5 liters for a full replacement cycle).
Make sure the car is on a level surface and the engine is turned off. Working on a hot engine is not recommended, as there is a risk of burns from hot parts or flying drops of oil. If the car has been parked in a garage, allow it to cool slightly, but do not leave it overnight to prevent the fluid from thickening too much.

Step-by-step replacement instructions
The procedure for changing the oil in the power steering system Nissan Almera Classic performed using the displacement method. This is the most effective method, allowing you to remove up to 90% of the old fluid without disassembling the connections. First you need to open the hood and find the power steering reservoir. It has transparent walls and markings MIN and MAX. Using a bulb or syringe, pump out as much of the old fluid as possible from the tank.
Then fill in new fluid up to the mark MAX. Do not overfill above this mark, as the level may rise and spill when the engine is running. After this, start the engine and let it idle for 1-2 minutes. There is no need to turn the steering wheel at this time. Monitor the level in the reservoir - it will drop as new fluid displaces old fluid from the system.
Stop the engine and add fluid again to the maximum. Now begin to smoothly rotate the steering wheel from lock to lock left and right, holding it in extreme positions for 2-3 seconds. This will help bleed the system and remove air. Repeat the procedure of starting the engine and turning the steering wheel several times until the fluid level stops falling and becomes stable.
What to do if the level does not drop?
If the fluid level does not drop after starting the engine, the filter in the reservoir may be clogged or the problem is in the pump itself. Try gently turning the steering wheel to extreme positions several times without turning on the engine to move the fluid. If the problem persists, check the coarse filter in the tank - it can be removed and washed.
After the level has stabilized, screw on the reservoir cap and wipe off any leaks with a clean rag. Start the engine and check the steering operation. The steering wheel should rotate easily and without noise. If you hear extraneous sounds, there may be air left in the system - repeat the bleeding procedure. Never leave the reservoir open while the engine is running, as the rotating belt may drag objects or your hand into the reservoir.
The basic principle of replacement is to repeatedly displace the old fluid with a new one by rotating the steering wheel with the engine turned off and running. This allows you to update the composition without removing the hoses.
Level check and condition monitoring
After changing the oil, it is necessary to regularly monitor its level and condition. On Nissan Almera Classic The power steering reservoir has transparent walls, which allows you to visually assess the amount of fluid without removing the cap. The check should be carried out on a cold engine with the car parked on a level surface. The level must be between the marks MIN and MAX.
If the level drops faster than expected, it may indicate a leak. Inspect all hoses, connections and the pump itself for leaks. Often the problem lies in worn out oil seals or cracks in rubber pipes. Also check the condition of the pump belt drive - weak belt tension can lead to slippage and overheating of the fluid.
- π Visual inspection β check the tank once a month, especially before long trips.
- π Liquid color - If the oil has darkened or become cloudy, schedule another change.
- π Pump noise - If a hum occurs, immediately check the level and quality of the fluid.
Do not operate the system with low fluid levels. The power steering pump operates in lubrication and cooling mode precisely due to the circulating oil. Running dry for even a few minutes can cause permanent damage to the pump bearing and impeller. If a critically low level is detected, immediately add fluid and find the cause of the leak.
Common mistakes and their consequences
Many owners Nissan Almera Classic make mistakes when servicing the power steering system, which can lead to serious damage. One of the most common mistakes is mixing different types of oils. For example, adding mineral oil to a system that is already filled with synthetics, or vice versa. This causes a chemical reaction that leads to the formation of sediment and blockage of the system channels.
Another mistake is ignoring the need to bleed the system after replacement. If air remains in the system, it causes cavitation (the formation of bubbles), which destroys the internal parts of the pump and creates a characteristic noise. Also, do not pour oil above the mark MAX, since when heated it expands and can squeeze out the lid or leak through the reservoir, hitting the belt and causing it to slip.
β οΈ Attention! Using oil with the wrong viscosity (for example, too thick) in winter may result in the pump being unable to pump fluid, causing it to overheat and quickly fail.
Also, do not delay changing the oil if it has changed color or smell. Old oil loses its lubricating properties and ceases to protect metal surfaces from wear. Regular replacement is a guarantee of long and reliable operation of the power steering system. Donβt expect noise or stiff steering to appear; change the fluid regularly every 60-80 thousand kilometers or every 3-4 years.
