Power steering oil Nissan Almera N16: a complete guide to selection and replacement

Nissan Almera N16 (2000–2006) is one of the most popular foreign cars on the secondary market, but its power steering (power steering) requires special attention. Owners often encounter pump noise, a stiff steering wheel, or fluid leaks - and this is due not only to wear and tear of parts, but also incorrectly selected oil.

In this article we will look at what kind of oil to fill in the power steering. Almera N16how to replace it correctly, and why even the original fluid Nissan PSF may not be suitable in some cases. And we’ll also reveal the secret of compatibility of oils from other brands, which saves up to 30% of the budget without risk to the system.

What kind of oil to fill in power steering Nissan Almera N16: official requirements

The manufacturer recommends for Almera N16 liquid Nissan PSF (Power Steering Fluid) with catalog number KE902-99931 or 999MP-AM000P. This is a mineral oil with a package of additives optimized for power steering systems Nissan early 2000s. However, there are nuances here:

• 🔹 Color: original liquid - red (not to be confused with ATF for automatic transmission!).
• 🔹 Specification: must match Dexron II or Dexron III, but no higher - modern oils with Dexron VI may damage the seals.
• 🔹 Base type: only mineral! Synthetics or semi-synthetics lead to leaks through the pump seals.

Important: if in your Almera N16 previously filled green oil (For example, Pentosin), mix it with red Nissan PSF you can't! This will cause a chemical reaction that will cause sediment to form and clog the power steering filter.

Analogues of the original oil: what can be filled without risk

Original liquid Nissan PSF is expensive (from 800 rubles per liter), but there are proven analogues that are not inferior in quality:

Brand	Liquid name	Color	Compatibility	Notes
Mobil	ATF 220 (Dexron II)	Red	100%	The best budget analogue. Suitable for all model years N16.
Liqui Moly	Central Hydraulic Oil	Red	95%	More fluid than the original. Recommended for cold climates.
Castrol	Transmax Dexron III	Red	90%	Undesirable for cars older than 2003 - may corrode old hoses.
Febi	PSF Fluid (item 22616)	Red	98%	A complete analogue of the original, but 20–30% cheaper.

⚠️ Attention: if in yours Almera N16 installed power steering gearbox from Renault (this happens on restyled models 2004–2006), use only ELF Renaultmatic D2 or Mobil ATF 220. Other oils may cause foaming in the system!

Signs that it’s time to change the power steering oil

B Nissan Almera N16 Power steering fluid does not have a strict replacement schedule, but there are clear symptoms of its wear:

• 🚨 Pump hum when turning the steering wheel (especially when cold).
• 🔧 Stiff steering wheel rotation in one of the extreme positions (left/right).
• 💧 Dark oil color (black or brown) and a burning smell.
• 🛑 Foam in the power steering reservoir - a sign of air or water ingress.
• 🔥 Steering rack overheating (the rack body is hot to the touch).

What happens if you don't change the oil?

If these signs are ignored, first the pump seals wear out (repair cost - from 5,000 rubles), then the steering rack fails (from 15,000 rubles). In critical cases, the pump shaft jams, which makes the machine uncontrollable while moving.

Check the oil level and condition every 20,000 km or once a year. To do this:

1. Open the hood and find the power steering reservoir (located on the left, next to the battery).
2. Wipe the tank with a clean cloth and check the level according to the marks MIN/MAX.
3. Drop oil onto white paper: if the color is cloudy or there are metal particles, replace it immediately!

Step-by-step instructions for changing power steering oil in Nissan Almera N16

To replace you will need: 1 liter of new fluid, syringe with tube (for pumping), key on 10 And 12, drainage container, rags.

Step 1. Drain the old oil

1. Pump out the maximum possible volume of liquid from the tank with a syringe.
2. Loosen the clamp and remove the return hose (lower reservoir hose).
3. Place an extension on the hose (you can use a hose from a dropper) and direct it into the container.
4. Ask an assistant to turn the steering wheel left and right until it stops - this will drive out the remaining oil.

Step 2: Flush the system (optional, but recommended for heavy soiling):

1. Pour into the tank 200–300 ml new oil.
2. Start the engine and turn the steering wheel several times.
3. Drain the flushing fluid and repeat the procedure 2-3 times.

Step 3. Filling with new oil

1. Reconnect the return hose and secure with a clamp.
2. Fill with fresh fluid up to the mark MAX.
3. Start the engine and slowly turn the steering wheel in both directions all the way (do not hold in the extreme position for more than 5 seconds!).
4. Add oil to the level and repeat the procedure 2-3 times.

Typical mistakes when changing power steering oil and how to avoid them

Even experienced car owners make mistakes that reduce the life of the power steering. Here are the most common:

⚠️ Attention: Never use automatic transmission oil (For example, Dexron VI) instead of specialized power steering fluid! It has a different viscosity and can destroy pump seals in 1–2 months.

• ❌ Mixing different types of oils (red with green, mineral water with synthetics). Consequence: formation of gel-like clots that clog the filter.
• ❌ Incomplete drainage of old fluid. Consequence: new oil quickly becomes contaminated, and the effect of replacement disappears after 5,000 km.
• ❌ Oil overflow above the MAX mark. Consequence: foaming and pump overheating.
• ❌ Using Hose Sealant. Consequence: Sealant particles clog the rack valves.

Another critical error - bleeding the system at high speeds. When changing the oil, the engine must be idling (800–900 rpm), otherwise the pump will trap air and will have to be pumped again.

Frequent power steering malfunctions after oil change

If problems appear after replacing the fluid, most likely the technology was broken. Let's consider typical cases:

Symptom	Possible reason	Solution
The steering wheel is heavier than before	Air in the system or incorrect oil	Bleed the system (see instructions below) or replace the fluid with the original
The hum of the pump increased	Low oil level or pump wear	Add liquid to MAX or check the pump for bearings
Leaking from under the tank or hoses	Damaged clamps or cracked hoses	Replace the clamps with worm clamps (article no. N90850101) and hoses
Foam in the tank	Air or water entering the system	Complete oil change with flushing

How to bleed the power steering after changing the oil

Bleeding is needed to remove air from the system. Do it necessarily, otherwise the steering wheel will “twitch” or turn hard.

1. Fill the oil up to the mark MAX.
2. Raise the front of the car with a jack (the wheels should be hanging in the air).
3. Start the engine and let it idle for 1-2 minutes.
4. SLOWLY turn the steering wheel all the way to the left, hold for 2-3 seconds, then to the right. Repeat 5-7 times.
5. Check the oil level and add if necessary.
6. Lower the car and repeat steps 3–5 2 more times.

⚠️ Attention: If foam is visible in the tank after pumping, repeat the procedure after 1–2 hours. Air could remain in the rack or hoses.

FAQ: Frequently asked questions about power steering oil Nissan Almera N16

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

No! Red oil (eg. Nissan PSF) has a mineral base, and green (Pentosin) - synthetic. When mixed, a sediment will form that will clog the filter and rack valves. If you don’t know what was uploaded earlier - completely drain the old fluid and flush the system.

How much oil is needed for a complete power steering change? Almera N16?

Total system volume - 0.8–1 liter. To replace, it is enough to buy 1 liter, but if you plan to flush, take 1.5 liters. The remainder can be used for topping up.

How often do you change power steering oil?

Official regulations Nissan — every 60,000 km or 4 years. But in Russian conditions (temperature changes, dust) it is recommended to reduce the interval to 40,000 km or 2 years. If the car is used in difficult conditions (taxi, off-road), replace the fluid after 30,000 km.

What to do if the steering wheel becomes stiff after changing the oil?

The reasons may be different:

• 🔹 Airing the system — pump up the power steering (instructions above).
• 🔹 Wrong oil - merge and fill the original Nissan PSF.
• 🔹 Pump or rack wear - diagnostics required.

If pumping doesn't help, check power steering belt tension (should bend by 8–10 mm) and hose condition (Aren't they bent?)

Can ATF be used instead of power steering oil?

Theoretically yes, but only if the ATF matches Dexron II or Dexron III (For example, Mobil ATF 220). However:

• 🔹 ATF viscosity is lower, so the power steering pump will work with increased load.
• 🔹 Additives in ATF are not optimized for power steering seals, which reduces their resource.

Use ATF only as a last resort (for example, on the road), and replace it with a specialized oil as soon as possible.
