Nissan PSF: a complete guide to the characteristics and application of the original fluid

Liquid Nissan PSF (Power Steering Fluid) - a specialized composition developed for power steering of cars of the brand Nissan. This fluid ensures smooth system operation, protects parts from wear and corrosion, and maintains stable performance in extreme temperatures. However, many owners are faced with questions: what Nissan PSF different from universal analogues? How often does it need to be changed? And can it be mixed with other liquids?

In this article we will analyze in detail technical specifications, chemical composition and performance properties Nissan PSF. You will find out which models Nissan require this particular fluid, how to check its condition and what to do in case of leaks. We will also compare the original liquid with popular substitutes and give recommendations on choice for different climatic conditions.

1. What is Nissan PSF: composition and purpose

Liquid Nissan PSF belongs to the class hydraulic oils for power steering (power steering) systems. Its main task is to transfer force from the pump to the actuators, reduce friction between parts and protect against oxidation. Unlike transmission or motor oils, PSF has a unique additive package adapted to the materials of seals and seals Nissan.

By chemical composition Nissan PSF refers to synthetic fluids based on polyalphaolefins (PAO) with the addition of:

• 🧪 Antifoam additives — prevent the formation of foam during intensive operation of the power steering pump.
• 🛡️ Antioxidant components — extend the service life of the fluid and protect metal parts from corrosion.
• 🔥 Thermal stabilizers — maintain viscosity in the range from -40°C to +120°C.
• 🔄 Friction modifiers — reduces wear of gears and bearings.

Important feature: Nissan PSF does not contain silicones, making it compatible with most rubber seals in power steering systems Nissan (unlike some silicone-based all-purpose fluids). This is critical for models with sensitive seals, for example, Nissan Qashqai J10 or X-Trail T31.

⚠️ Attention: Using liquids containing silicone (eg Pentosin CHF 11S) in systems designed for Nissan PSF, can lead to swelling of the seals and leaks!

2. Technical characteristics of Nissan PSF

Original liquid Nissan PSF meets the manufacturer’s strict standards and has the following key parameters:

Parameter	Meaning	Note
Color	Red (sometimes amber)	Color may change over time, but should not turn black
Viscosity at 40°C	32–35 mm²/s	Optimal for power steering pump operation in the urban cycle
Freezing point	-45°C	Guarantees work in the northern regions
Boiling point	+230°C	Prevents the formation of vapor locks due to overheating
Quality standard	Nissan KE902-99931	Original article for ordering

Particular attention should be paid viscosity-temperature properties. The liquid remains fluid even when -30°C, which is critical for winter operation. For example, in Nissan Murano Z51 with electric hydraulic booster (EHPS) Using too thick a liquid can lead to increased load on the pump and its premature wear.

For comparison: universal class fluids ATF Dexron III have a viscosity of ~7–8 mm²/s at 100°C, whereas Nissan PSF - about 6.5 mm²/s under the same conditions. This makes it "lighter" for systems with high pump speeds.

3. Compatible with Nissan models

Liquid Nissan PSF recommended by the manufacturer for most models with power steering released after 2000. However, there are nuances:

• 🚗 Qashqai (J10, J11) - demands PSF for all versions with power steering, including diesel.
• 🚙 X-Trail (T30, T31, T32) - original fluid is required for models with 2.5 MR20DE And 2.0 MR20DD.
• 🏙️ Note (E11, E12) - in versions with EHPS (electric hydraulic booster) it is allowed to use Nissan E-PSF.
• 🛻 Navara (D40, NP300) - for diesel engines YD25DDTi A shortened replacement interval is recommended (every 60,000 km).

Exceptions:

• ⚡ Models with electric power steering (EPS) (For example, Nissan Leaf or Ariya) do not require power steering fluid.
• ⚠️ Nissan GT-R (R35) uses a specialized liquid Nissan Matic S for power steering, not compatible with PSF!

To determine exact compatibility, check:

1. The inscription on the cover of the power steering reservoir (there should be a mark PSF or Power Steering Fluid).
2. Operating manual (section "Technical Fluids").
3. The label on the original canister (item number KE902-99931).

How to check fluid compatibility with your model?

If the manual specifies a standard Nissan PSFbut you are in doubt, run the test:

1. Drain 50 ml of old liquid into a transparent container.

2. Add 10 ml of new fluid.

3. Stir and leave for 24 hours.

If sediment or separation appears, the liquids are incompatible!

4. When and how often to change Nissan PSF

Manufacturer Nissan does not always indicate clear power steering fluid replacement intervals, but experts recommend adhering to the following rules:

• 📅 Standard interval - every 100,000 km or 5 years (whichever comes first).
• ⚠️ Difficult conditions (frequent off-road driving, towing, extreme temperatures) - every 60,000 km.
• 🔧 After renovation Power steering (replacement of pump, rack, hoses) - mandatory fluid replacement.

Signs that the fluid needs replacing:

• 🔴 Darkening of color (from red to brown or black).
• 🌊 The appearance of foam or cloudy sediment.
• 💨 Burning smell (indicates overheating).
• 🔊 Extraneous noise when turning the steering wheel (creaking, humming).

To check the condition of the fluid:

1. Open the hood and find the power steering reservoir (usually next to the pump, marked with a cap that says PSF).
2. Wipe the dipstick with a clean cloth and put it back down.
3. Take out the dipstick and evaluate the color, smell and consistency.

⚠️ Attention: If the fluid has metal particles or a strong odor, this is a sign of wear on the pump or rack! In this case, system diagnostics are required, and not just fluid replacement.

1. Purchase original liquid (article KE902-99931)

2. Prepare a syringe for pumping out old fluid

3. Buy a new tank filter (if necessary)

4. Warm up the engine to operating temperature (50–60°C)

5. Raise the front of the car to completely drain it-->

5. Step-by-step instructions for replacing Nissan PSF

Replacing power steering fluid Nissan - a procedure that can be performed independently with a minimum set of tools. It is important to follow the algorithm to avoid air entering the system.

Required materials:

• 🛢️ Original liquid Nissan PSF (1–1.5 liters).
• 🔧 Syringe volume 50–100 ml with a tube.
• 🧻 Clean napkins and drainage container.
• 🔩 Key on 10 mm (to loosen hose clamps).

Procedure:

1. Draining old fluid:
   • Suck out the liquid from the tank with a syringe.
   • Loosen the clamp on the bottom hose of the tank and drain the residue into a container.
   • Turn the steering wheel left and right (with the engine off) to expel fluid from the system.
2. Flushing (optional):
   • Fill in 200–300 ml new fluid, turn the steering wheel, drain.
   • Repeat 2-3 times to remove sediment.
3. Refilling with new fluid:
   • Reconnect the hose and tighten the clamp.
   • Fill the liquid up to the mark MAX on the tank.
   • Заведите двигатель, несколько раз поверните руль до упора.
   • Add fluid to the level (with the engine running).

After replacement, check:

• No leaks around the tank and hoses.
• Ease of rotation of the steering wheel (there should be no jerking or humming).
• Liquid color through 1,000 km (if it gets dark, it needs to be replaced again).

6. Comparison of Nissan PSF with analogues

Many owners Nissan They are wondering: can analogues be used instead of the original liquid? The answer depends on the model and operating conditions. Consider popular substitutes:

Liquid	Compatible with Nissan PSF	Pros	Cons
Febi 06161	Full	Low price, good anti-foam properties	Less resource (replacement every 80,000 km)
Mobil ATF 320	Partial	High thermal stability	May cause swelling of seals in older models
Castrol Transmax Dex III	Limited	Widely available	Not suitable for systems with high loads (e.g. Navara)
Pentosin CHF 11S	Incompatible	Excellent low temperature properties	Silicone base - risk of leakage

Recommendations for selection:

• 🚗 For Qashqai, X-Trail, Note - only original or Febi 06161.
• 🏗️ For Navara, Pathfinder - only Nissan PSF (high loads on power steering).
• ❄️ For northern regions - original or Febi (better low temperature fluidity).

If you decide to use an analogue, be sure to:

1. Check compatibility by VIN on the website of the liquid manufacturer.
2. Mix a small amount of old and new fluid for a sludge test.
3. Reduce replacement interval by 20–30%.

7. Common problems and their solutions

Problems associated with power steering fluid often appear gradually. Let's look at typical symptoms and ways to eliminate them:

Problem 1: Pump noise when turning the steering wheel

• Reason: low fluid level or degradation.
• Solution: add fluid to the level MAX or replace completely. If the hum remains, check the pump.

Problem 2: Stiff steering when cold

• Reason: thickened liquid (especially if non-original is used).
• Solution: replace the fluid with Nissan PSF and check operation after warming up.

Problem 3: Fluid leaks

• Reason: worn rack seals or hoses, incompatible fluid.
• Solution:
  • Replace damaged hoses (part numbers for Qashqai J11: 48520-4M00A - top, 48521-4M00A - lower).
  • Flush the system and refill with original fluid.

Problem 4: Foam in the power steering reservoir

• Reason: air or water entering the system.
• Solution:
  1. Check the tightness of the hoses and clamps.
  2. Replace pre-flush fluid.
  3. If foam appears again, diagnose the pump for air leaks.

⚠️ Attention: If, after replacing the fluid, the steering wheel begins to “jump” when turning, this is a sign of air in the system! It is necessary to bleed the power steering: with the engine running, turn the steering wheel several times all the way in both directions, then add fluid.

FAQ: Frequently asked questions about Nissan PSF

Is it possible to mix Nissan PSF with other power steering fluids?

Mixing is only allowed with liquids that have an identical composition (for example, Febi 06161). Categorically cannot be mixed with:

• Silicone fluids (Pentosin CHF 11S).
• Mineral ATFs (eg. Dexron II).
• Universal fluids based on glycols.

When mixing incompatible fluids, there is a risk of sediment formation and blockage of the power steering channels!

How to spot a fake Nissan PSF?

The original liquid has the following characteristics:

• Canister with holographic sticker and article number KE902-99931.
• The color of the liquid is clear red (not cloudy).
• There is no sediment at the bottom of the canister.
• When shaken, the foam settles behind 10–15 seconds.

Counterfeits often have a strong chemical smell and are darker in color.

What happens if you don't change your Nissan PSF?

Consequences of ignoring replacement:

• Increased wear on the power steering pump (the cost of a new one is from 15 000 ₽).
• Seizures on the rail vines (repairing the rail costs 20 000–40 000 ₽).
• Increased steering play and deterioration in controllability.
• Blockage of the tank filter (leads to starvation of the pump).

Critical case: the power steering pump jams, which can lead to loss of control!

Can Nissan PSF be used in other brands of cars?

Liquid compatible with some models Renault, Infiniti And Mitsubishi, where the standard is also used PSF. However:

• For Renault with power steering is often recommended Renaultmatic D3 SYN.
• B Infiniti (For example, QX50) can be used Nissan PSF, but with a reduced replacement interval.
• For Mitsubishi (For example, Outlander) it is better to use Mitsubishi PSF (article MZ320277).

Always check the manual for your specific model!

How to dispose of used Nissan PSF fluid?

Waste power steering fluid belongs to hazardous waste (hazard class 3–4). Disposal rules:

• Take it to waste oil collection points (for example, service stations or eco-centers).
• Do not pour into drains or onto the ground - Nissan PSF toxic to water bodies.
• Store the waste in a tightly closed container (for example, in a canister of new fluid).

In Moscow and St. Petersburg, testing reception is organized at most official service stations Nissan.
