Nissan PSF-KLF50-00001: a complete guide to hydraulic steering fluid

If you are a car owner Nissan with power steering (power steering) or electric power steering (EPS), then sooner or later you will be faced with the need to maintain the system. One of the key components here is a special liquid - Nissan PSF-KLF50-00001. This article often raises questions: what does it mean, where is it used, and can analogues be used?

In this article we will analyze in detail unique properties of the original liquid PSF-KLF50-00001, its difference from universal analogues, and we will also provide step-by-step instructions for replacement - taking into account the nuances for different models Nissan. We will pay special attention to compatibility with systems EPS (for example, in Qashqai J11 or X-Trail T32), where an error in the choice of fluid can lead to damage to the amplifier.

What is Nissan PSF-KLF50-00001 and what is it for?

Article PSF-KLF50-00001 stands for original hydraulic fluid for steering systems Nissan. Abbreviation PSF stands for Power Steering Fluid — power steering fluid. However, its application is wider: it is also used in some systems EPS (electric booster), where lubrication of mechanical parts is required.

Main functions of the liquid:

• 🔧 Lubrication moving parts of the power steering pump and rack, reducing wear.
• 🔥 Heat dissipation from overheated components (especially important for severe operating conditions).
• 🛡️ Corrosion protection metal parts and seals.
• 🌀 Power transmission in hydraulic systems (for classic power steering).

Important: PSF-KLF50-00001 - this is not universal ATF (like for example Dexron III), but a specialized product designed to meet the requirements Nissan. Its composition is optimized to work with rubber seals and plastic parts of steering systems of specific models.

Technical characteristics and composition of the liquid

Original liquid PSF-KLF50-00001 belongs to the class synthetic hydraulic oils with a package of additives providing:

• 🌡️ Viscosity stability over a temperature range -40°C…+120°C.
• 🔬 Low foaming (critical for the durability of the power steering pump).
• 🛢️ Compatible with seal materials (rubber NBR, EPDM).
• 🔄 Long service life (up to 100,000 km or 5 years under normal conditions).

Comparison with analogues:

⚠️ Attention: Power steering fluids and EPS often confused with ATF (automatic transmission oil). Usage Dexron or Mercon in the steering system Nissan can lead to destruction of the seals and failure of the rack!

Compatible with Nissan models: where PSF-KLF50-00001 applies

Liquid PSF-KLF50-00001 recommended for the following models (the list is incomplete, please check VIN):

• 🚗 Nissan Qashqai (J10, J11) - Power steering and EPS.
• 🚙 Nissan X-Trail (T31, T32) - power steering only (T32 with EPS uses a different fluid!).
• 🚐 Nissan Navara (D40) - Power steering.
• 🚖 Nissan Teana (J32) - power steering.
• 🚗 Nissan Juke (F15) - EPS (only for models up to 2017).

Critical nuances:

• B X-Trail T32 with EPS (electric booster) is used other liquid — NS-3 or E-PSF. PSF-KLF50-00001 cannot be poured there!
• B Qashqai J11 with EPS (after 2014) the original fluid is poured only into the mechanical part of the system (if any).

How to check which steering system is in your Nissan?

1. Look under the hood: if there is a fluid reservoir and hoses to the pump, this is power steering. 2. If under the hood there is only an electric motor on the steering column, this is EPS. 3. In the manual, look for the section "Power Steering System" or "Electric Power Steering".

When and how often to change the fluid PSF-KLF50-00001

Official recommendations Nissan for replacing fluid in the steering system:

• 📅 Power steering (hydraulic booster): every 100,000 km or 5 years (whichever comes first).
• ⚡ EPS (electric power steering): replacement is not provided, but in case of repairs or leaks, the original fluid is added.

Signs that it’s time to change the fluid:

• 🔊 Noise or hum power steering pump when turning the steering wheel.
• ⚠️ Tight rotation steering wheel at low speeds.
• 🟢 Darkening of the liquid (a sign of oxidation or contamination).
• 💧 Leaks from under seals or hoses.

💡

Before replacing the fluid, check the condition of the power steering hoses for cracks and abrasions. If they are worn out, replace them along with the fluid - this will prevent re-contamination of the system.

Step-by-step instructions for replacing fluid PSF-KLF50-00001

To change the fluid in the power steering system you will need:

• 🔧 Set of keys (10 mm, 12 mm).
• 🛢️ Original liquid PSF-KLF50-00001 (1–1.5 l).
• 🔩 Syringe or vacuum pump for pumping.
• 🧤 Gloves and rags.

☑️ Preparing to replace power steering fluid

Raise the front of the car on jacksRemove the crankcase protection (if it interferes)Prepare a container to drain the old fluidWarm up the engine to operating temperature (50–60°C)

Done: 0 / 4

Step 1: Drain the old fluid

1. Open the power steering reservoir cap and pump out the fluid with a syringe.
2. Loosen the clamp on the return hose (usually the lower reservoir hose) and remove it.
3. Place an extension on the hose (for example, a hose from a drip) and direct it into a drainage container.
4. Ask an assistant to turn the steering wheel left and right until it stops (the engine is off!). This will flush any remaining fluid from the system.

Step 2: Flush the system (optional)

If the fluid is heavily contaminated, flushing is recommended:

1. Pour into the tank 300–500 ml new fluid.
2. Start the engine and turn the steering wheel in both directions (not all the way!).
3. Drain the flushing fluid and repeat the procedure 2-3 times.

Step 3. Filling with new fluid

1. Connect the return hose back to the tank and secure with a clamp.
2. Fill the liquid up to the mark MAX on the tank.
3. Start the engine and slowly turn the steering wheel left and right (all the way) 3–5 times.
4. Add fluid to the level (it will go into the system during operation).
5. Check that there is no air in the system: there should be no “dips” or jerks when turning the steering wheel.

💡

After replacing the fluid, be sure to check the tightness of the connections! A leak can cause air to enter the system and cause the power steering pump to fail.

Analogues of PSF-KLF50-00001: what can be filled instead of the original

If the original liquid is not available, you can use certified analogues, meeting specifications Nissan:

Manufacturer	Article	Type	Notes
Febi	06162	Semi-synthetics	Suitable for power steering, but not for EPS
Liqui Moly	7501	Synthetics	Color yellow, compatible with rubber seals
Ravenol	4014835734606	Synthetics	Approved for Nissan And Infiniti
Mobil	ATF 320	Synthetics	Only for power steering, not for EPS!

⚠️ Attention: In systems EPS (For example, Qashqai J11 or X-Trail T32) the use of analogues can lead to malfunctions of the electronics! Only original liquid or Nissan E-PSF (article KE909-99932).

💡

Before purchasing an analogue, check its compatibility with your model on the manufacturer's website. For example, Febi 06162 not suitable for Nissan Juke with EPS, but acceptable for Teana J32 with power steering.

Common mistakes when replacing fluid and how to avoid them

Even experienced car owners make mistakes when servicing the steering system. Here are the most common:

• 🔄 Mixing different types of liquids. For example, PSF-KLF50-00001 (red) with Liqui Moly PSF (yellow). This leads to foaming and loss of properties.
• 🚫 Using ATF instead of PSF. Automatic transmission oils (Dexron) have a different additive package and destroy power steering seals.
• 💨 Air entering the system. Air pockets cause “dips” when turning the steering wheel and can damage the pump.
• 🔧 Incorrect pumping. After changing the fluid, you need to turn the steering wheel with the engine running, and not with the engine turned off!

How to avoid problems:

• Always use only one brand of liquid (do not mix).
• When topping up, use the same fluid that has already been filled in (if you don’t know, flush the system).
• After replacement, check the fluid level through 1–2 days - Topping up may be required.

What should I do if the steering wheel becomes stiff after changing the fluid?

1. Check the fluid level - it may be missing. 2. Make sure that there is no air in the system (you need to bleed it by turning the steering wheel with the engine running). 3. If the problem remains, check the power steering pump for wear or malfunction.
