Power steering oil for Nissan Almera Classic: how to choose and replace without mistakes

Nissan Almera Classic (internal designation B10) is one of the most popular foreign cars on the secondary market in Russia and the CIS. Despite the simplicity of the design, the power steering system of this car requires attention, especially when it comes to choosing and replacing the working fluid. Incorrect oil or late maintenance may result in power steering pump hum, a tight steering wheel or even a broken rack.

In this article we will analyze what kind of oil to put in power steering Almera Classic (including restyled versions 2006–2012), how often to change it, and why some “universal” fluids can harm the system. You will also find step-by-step instructions for replacement, taking into account typical errors and unique nuances specifically for this model - for example, why after changing the oil the steering wheel may become heavier when cold.

What kind of oil is poured into the power steering Nissan Almera Classic from the factory?

From factory to power steering Nissan Almera Classic (all modifications, including engines 1.5 And 1.6) liquid is poured Nissan PSF (Power Steering Fluid) with catalog number KE902-99931. This mineral oil red, corresponding to the standard Dexron II or Dexron III.

Important: despite the fact that Dexron II considered obsolete for Almera Classic it remains preferred. The fact is that more modern liquids (for example, Dexron VI) have a different additive package that can have an aggressive effect on the rubber seals of the pump and rack, especially on cars with mileage over 150 thousand km.

• 🔴 Color: red (not to be confused with ATF for automatic transmission, which is also red, but has a different composition!).
• 📦 Original article: KE902-99931 (1 l) or KE902-99932 (12 l for service stations).
• ⚠️ Incompatibility: should not be mixed with green or yellow oils (for example, Febi or Liqui Moly for power steering).

If the original oil is difficult to find, analogues are allowed:

Brand	Article	Type	Notes
Mobil	152621	ATF Dexron III	Suitable for replacement, but may be lighter in viscosity
Castrol	157AB9	ATF Dexron III	A good analogue, but do not mix with the original
Motul	105777	Dexron III	Often counterfeited - buy from authorized dealers
Ravenol	4014835734547	PSF Fluid	Specialized fluid for power steering, close to the original

⚠️ Attention: If in your Almera Classic Previously, green or yellow oil was poured (for example, Febi 06161), before replacing with red be sure to flush the system! Mixing different types of liquids leads to the formation of flakes that clog the pump filter.

When to change power steering oil: signs and regulations

Official regulations Nissan does not provide for the replacement of power steering fluid throughout the entire service life of the vehicle. However, in practice this leads to premature pump wear and slats, especially in the Russian climate with sudden temperature changes.

Recommended replacement intervals:

• 🔄 Every 60–80 thousand km or once every 3-4 years - for prevention.
• 🚨 Immediate replacement when appearing:
  • power steering pump hum when cold or hot;
  • heavy steering wheel in one of the extreme positions;
  • darkening or cloudiness of the liquid;
  • air bubbles in the tank (a sign of suction or leakage).

You can check the condition of the oil visually:

1. Open the power steering reservoir cap (located to the right of the engine, next to the windshield).
2. Drop the liquid onto a white paper napkin.
3. If oil:
   • 🟢 Transparent, red tint - normal.
   • 🟠 Dark brown, with particles - requires replacement.
   • ⚫ Black, with a burning smell — urgently change + check the pump!

Step-by-step instructions for changing power steering oil in Nissan Almera Classic

Replacing power steering fluid with Almera Classic does not require a special tool, but there are several critical nuancesthat are often missed:

1. Preparation:
   • Place the car on a level surface.
   • Raise the front part on jacks or a platform (needed to completely drain the old oil).
   • Prepare:
     • 1–1.5 liters of new oil;
     • syringe with a tube (for pumping out of the tank);
     • wrench 10 (to remove the tank if flushing is required);
     • clean rags.
2. Draining old oil:
   • Suck out the liquid from the tank with a syringe.
   • Loosen the clamp on the return hose (lower tank hose) and remove it. Place an extension on the hose (for example, from a dropper) and direct it into the container.
   • Ask an assistant to turn the steering wheel from lock to lock 5-6 times until all the fluid is drained.
3. Flushing the system (optional):
   When is flushing needed?

   Flushing is required if:

   - You don’t know what kind of oil was filled in earlier.

   - The liquid in the reservoir is black or has flakes.

   - After replacement, the steering wheel became heavier or a hum appeared.

   For washing, use special compounds (for example, Wynns Power Steering Flush) or fresh power steering oil. Pour it into the system, twist the steering wheel, then drain and repeat 2-3 times.

4. Refilling with new oil:
   • Connect the return hose back to the tank.
   • Fill with fresh fluid up to the mark MAX.
   • Rotate the steering wheel from lock to lock 10–15 times to distribute the oil throughout the system.
   • Add fluid to the level (after bleeding the level will drop).

⚠️ Attention: After changing the oil, the steering wheel may become heavier when cold in the first 1-2 days. This is normal - the liquid should be evenly distributed throughout the system. If tightness persists, check presence of air in the system (you need to bleed the power steering again).

Typical mistakes when changing power steering oil and their consequences

Even experienced car owners make mistakes that lead to pump breakdown or slats. Here are the most common:

• 🔴 Mixing different types of oils.

  For example, adding green Febi in red Nissan PSF. The result: the formation of gel-like clots that clog the pump filter. Symptoms: hum when turning the steering wheel, jerking.

• 🔴 Using ATF for automatic transmissions instead of PSF.

  Automatic transmission fluids (for example, Dexron VI) have a different additive package and viscosity. On Almera Classic this leads to accelerated wear of rack seals and leaks.

• 🔴 Incomplete drainage of old oil.

  If the system is not flushed, the new oil will mix with the old oil and its properties will deteriorate. This is especially critical if the old oil was black or had metal shavings.

• 🔴 Overfilling or underfilling liquid.

  Excess oil leads to foaming and leakage through the reservoir breather. The disadvantage is air leaks and pump noise.

1. Liquid level (must be between MIN and MAX).

2. The presence of air in the system (you need to bleed it by turning the steering wheel several times with the engine off).

3. Quality of oil - perhaps it was a fake.-->

What to do if after changing the oil the steering wheel becomes heavier

If after replacing the power steering fluid the steering wheel becomes stiff, the reasons may be as follows:

Reason	Symptoms	Solution
Air in the system	The steering wheel is tight, gurgling sounds are heard	Bleed the power steering (turn the steering wheel 10–15 times with the engine off, then add oil)
Poor quality oil	Tightness persists after warming up, humming is possible	Replace the fluid with the original one Nissan PSF or proven analogue
Dirty pump filter	The steering wheel is heavier in one of the extreme positions	Flush the system or replace the filter (requires disassembling the pump)
Worn rack or pump	Tightness + knocking or play in the steering wheel	Diagnostics at a service station, possible repair or replacement of components

If pumping doesn't help, try the following:

1. Check power steering belt condition - it could have weakened or worn out.
2. Make sure hoses are not pinched (sometimes after repairs they forget to fasten them correctly).
3. If the oil foams, it may be air leak through cracks in hoses or seals.

Alternative methods of power steering maintenance: flushing and additives

If the power steering oil has not been changed for a long time or the system operates intermittently, you can use flushing or additives. However, they must be treated with caution:

• 🧪 Flushing the system:

  Special formulations (for example, Wynns Power Steering Flush) help remove deposits and old oil residues. But on Almera Classic with mileage >200 thousand km, flushing can wash away deposits that covered microcracks in the oil seals, which will lead to leakage.

• ⚗️ Additives for power steering:

  Additives type Liqui Moly ATF Additiv or Hi-Gear Power Steering Treatment can temporarily improve pump performance, but do not replace a full oil change. On worn slats, they often have the opposite effect - they increase leaks.

• 🔧 Partial replacement:

  If it is not possible to completely drain the oil, you can pump out the old fluid with a syringe 2-3 times at an interval of 100 km and add new one. It's less effective, but better than nothing.

⚠️ Attention: Do not use kerosene or gasoline based washes! They destroy the power steering rubber seals. For Almera Classic Only specialized formulations based on mineral oils are suitable.

Where to buy original power steering oil for Nissan Almera Classic

Original oil Nissan PSF (KE902-99931) you can buy:

• 🛒 Online stores:
  • Exist.ru, Emex.ru, Autodoc.ru – there are often discounts, but check the seller’s reviews.
  • AliExpress - cheaper, but there is a high risk of running into a fake.
• 🔧 Car markets: You can find it cheaper, but there is a high chance of buying a counterfeit. Always check:
  • presence of a hologram on the packaging;
  • production date (fresh oil is lighter);
  • consistency (the original should not be too liquid).

When purchasing analogues, pay attention to:

• 📌 Standard: must be indicated Dexron II or Dexron III (not Dexron VI!).
• 📌 Color: only red (green or yellow oil is not suitable!).
• 📌 Composition: mineral or semi-synthetic (full synthetics are not recommended).

FAQ: Frequently asked questions about power steering oil for Nissan Almera Classic

Is it possible to fill it into the power steering? Almera Classic automatic transmission oil?

Technically possible, but only if it complies with the standard Dexron II or Dexron III. However, the original oil Nissan PSF better suited for rubber sealing systems. Automatic transmission fluids (for example, Dexron VI) have a different additive package and can reduce the life of the pump.

How much oil is needed for a complete power steering change?

To the power steering system Nissan Almera Classic fits about 0.8–1 liter liquids. A complete flush replacement may require up to 1.5 l (part of it will be used to displace old oil).

Why did the pump hum after changing the oil?

Most likely reasons:

1. Air has entered the system - you need to bleed the power steering.
2. Poor quality or incompatible oil - replace with the original.
3. Pump wear - If the hum persists after bleeding, repair may be required.

Is it possible to mix red and green power steering oil?

No! Red oils (mineral based, Dexron) and green (synthetic based) have different additives. Mixing them leads to the formation of flakes, which clog the pump filter and damage it.

How often should you check the power steering oil level?

It is recommended to check the level every 10–15 thousand km or once every six months. Power steering reservoir Almera Classic transparent, so can be inspected visually. Critical level - when the liquid is below the mark MIN.
