Changing the oil in the Nissan Qashqai J11 variator: complete instructions with nuances

CVT Nissan Qashqai J11 - a reliable, but maintenance-demanding unit. Many owners are faced with the question: is it possible to change the oil themselves without resorting to service? The answer is yes, but only with strict adherence to technology. In this article we will analyze complete process of changing the oil in the J11 variator, including selecting consumables, draining old fluid, flushing and filling with new fluid, as well as resetting the oil aging counter.

Official regulations Nissan prescribes changing the oil in the variator every 60,000 km (or once every 4 years), but more often under severe operating conditions. Skipping this procedure will result in accelerated wear of the belt, bearings and valve body, which will ultimately result in expensive repairs. We will describe each stage in detail so that even a beginner can complete the task without errors.

What kind of oil to fill in the Nissan Qashqai J11 variator

Choosing your oil is a critical step. CVT Jatco JF016E, installed on Qashqai J11, requires specialized fluid NS-3. Using other types (such as NS-2 or generic ATF) will result in incorrect operation of the transmission and possible failure.

Original oil from Nissan has an article number KE909-99945 (4 liters) or KE909-99944 (1 liter). Alternative options with NS-3 approval:

• 🔹 Idemitsu CVT Type NS-3 - a complete analogue of the original, often used in services
• 🔹 Ravenol CVT NS-3 — German oil with improved cleaning properties
• 🔹 Mobil CVT NS-3 - budget option, but with good reviews

Oil volume for complete replacement (with removing the pan and replacing the filter) - 7.8–8.2 liters. For partial replacement (without rinsing) 4–5 liters will be enough. Don’t skimp on quality: cheap analogues can cause belt slippage and overheating of the variator.

⚠️ Attention: If the variator previously used NS-2 oil, before switching to NS-3 it is mandatory complete flushing of the system with filter replacement. Mixing different types of liquids is unacceptable!

Tools and consumables for oil change

To work, you will need a standard set of tools, but there are also specific devices. Here's the full list:

Category	Name	Note
Consumables	Oil NS-3 (8 l)	It's better to take extra
Consumables	Variator filter	Article 31726-3MX0A (original) or JS Asakashi JT519K (analog)
Consumables	Pan gasket	Article 31397-3MX0A (it is recommended to change each time the pan is removed)
Tools	10 mm wrench	To unscrew the pallet bolts
Tools	19 mm head	For drain plug
Tools	Funnel with extension	To fill oil through the dipstick
Other	Drain container (minimum 6 l)	It is better to use a wide pelvis
Other	Lint-free rags	For cleaning the tray and magnets

Additionally you may need:

• 🔧 Torque wrench - for tightening the drain plug with a torque 35–40 Nm
• 🔧 Oil syringe - if filling through the dipstick is difficult
• 🔧 Scanner ELM327 — to reset the oil aging counter (optional)

Warm up the variator to 50–60°C (drive 10–15 km)

Place the car on a flat surface

Raise the front end using jacks or a lift

Prepare a drain container and tools

Disconnect the negative terminal of the battery (optional, for safety) -->

Step-by-step instructions: draining old oil

We start by removing the waste fluid. This step requires care as the oil will be hot.

Step 1. Warming up the variator

Start the engine and let it run for 5–7 minutes, or drive 10–15 km. The oil temperature should be 50–60°C - this will ensure better drainage. Check the temperature using a scanner (parameter CVT Fluid Temp) or by touch (the tray should be warm, but not scalding).

Step 2: Drain the oil

1. Place the car on flat surface and lock the rear wheels.
2. Raise the front end using jacks or a lift. Protect yourself with stops!
3. Unscrew drain plug (19 mm wrench) and drain the oil into a prepared container. Be careful - the liquid will leak out under pressure.
4. Wait until it drains completely (about 5-7 minutes). In the variator Qashqai J11 drains approximately 4.5–5 liters with partial replacement.

Step 3. Removing the pan and cleaning

After draining, unscrew 18 pan bolts (10 mm wrench) and carefully remove it. Inside you will find two magnets - they need to be thoroughly cleaned of metal shavings. Wash the tray itself gasoline or kerosene, removing any remaining old oil and deposits. Pay special attention coarse filter (mesh) - if it is heavily soiled, it is better to replace it.

What to do if the drain plug does not unscrew?

If the plug is stuck, do not use excessive force - you risk breaking the thread. Try:

1. Treat the threads with WD-40 and wait 10–15 minutes.

2. Use an impact wrench with a 19 mm socket.

3. Heat the cork with a hair dryer (do not overheat!).

If all else fails, contact a service center to drill and cut a new thread.

Replacing the variator filter and washing

Variator filter Qashqai J11 consists of two parts: coarse filter (metal mesh in the tray) and fine filter (paper element inside the case). When changing the oil completely, it is recommended to change both.

Replacing the fine filter:

1. Unscrew 3 bolts filter mounting (10 mm wrench).
2. Remove the filter housing and replace the paper element with a new one. Original article - 31726-3MX0A.
3. Check the condition of the sealing ring on the body - replace if damaged.
4. Reinstall the filter and tighten the bolts to torque. 10 Nm.

Flushing the variator:

If the oil is heavily contaminated (black color, burning smell), flushing is recommended. To do this:

1. After draining the old oil, refill 1–2 liters of new NS-3 oil.
2. Start the engine and let the CVT run 3–5 minutes in mode P.
3. Toggle the selector across all positions (P → R → N → D), holding each for 10 seconds.
4. Drain the flushing oil and repeat the procedure 2-3 times until the fluid is clear.

⚠️ Attention: When flushing do not use special flushing fluids - they can damage the rubber seals of the variator. Use only original NS-3 oil!

Filling with new oil and checking the level

Filling oil into the variator Qashqai J11 has its own nuances. The main rule is don't overfill, since excess oil is just as harmful as its lack.

Step 1. Installation of the pallet

Before installing the tray:

1. Clean the mating surfaces of the pan and the variator housing from the old gasket.
2. Apply a thin layer sealant (For example, Loctite 574) onto the gasket or surface of the pallet.
3. Install the pan and tighten the bolts evenly criss-cross moment 10 Nm.

Step 2. Filling with oil

Oil is poured through probe hole (located next to the battery). Use a funnel with an extension. Algorithm:

1. Fill in 4 liters of new oil.
2. Start the engine and let it idle for 2-3 minutes.
3. Toggle the selector across all positions (P → R → N → D), holding each for 5–10 seconds.
4. Check the oil level with a dipstick - it should be between the marks MIN And MAX at temperature 50–60°C.
5. Add oil to the desired level (usually another 0.5–1 liter is required).

Step 3. Control check

After filling:

• 🔧 Take a test drive of 5–10 km, including acceleration and braking.
• 🔧 Recheck the oil level on a hot variator.
• 🔧 Make sure there are no leaks from under the pallet and drain plug.

Resetting the oil aging counter

CVT Qashqai J11 equipped oil aging counter, which tracks its resource. After replacement, this counter must be reset to zero, otherwise the ECU will assume that the oil is still old and may incorrectly adjust the operation of the transmission.

Method 1: Using an ELM327 scanner

The easiest method is to use an adapter ELM327 (version 1.5) and program CVTz50:

1. Connect the adapter to the diagnostic connector (located under the steering wheel).
2. Run the program CVTz50 on a smartphone or PC.
3. Go to section Service Functions → Oil Degradation Reset.
4. Click Reset and confirm the operation.

Method 2: Manual reset (without scanner)

If you don’t have a scanner, you can reset the counter manually:

1. Turn on the ignition (do not start the engine).
2. Press the gas pedal all the way and hold.
3. Move the selector to position D, then N, then R, and again P.
4. Release the gas pedal.
5. Turn off the ignition for 10 seconds, then turn on again.
6. Repeat the procedure 3 times.

⚠️ Attention: Manual reset does not work on all versions of ECU firmware. If after the procedure the indicator on the dashboard lights up CVT, the counter has not reset to zero - you will need a scanner.

Common mistakes and how to avoid them

Even experienced car owners sometimes make mistakes when changing the oil in a CVT. Here are the most common:

Error	Consequences	How to avoid
Using NS-2 oil instead of NS-3	Belt slippage, overheating, variator failure	Check the label on the canister - it should be clearly stated NS-3
Incomplete drainage of old oil	Mixing old and new oil, reducing service life	Use a vacuum pump to pump the oil out of the pan or flush it
Overfilling or underfilling oil	Oil foaming, insufficient pressure, jerking when switching	Check the level on a warm variator (50–60°C) using the dipstick
Failure to reset the oil aging counter	The ECU continues to use “old” algorithms, accelerated wear	Reset the counter using a scanner or manually
Use of flushing fluids	Destruction of rubber seals, leaks	Flush only with original NS-3 oil

Another typical problem is oil leak after change. Most often it occurs due to:

• 🔧 Incorrectly installed pallet gasket (distortions, insufficient tightening of bolts).
• 🔧 Damaged thread of the drain plug (if it was tightened with excessive force).
• 🔧 Poor quality sealant (use only specialized compounds for CVT).

FAQ: Frequently asked questions about changing the oil in the Qashqai J11 variator

Is it possible to partially change the oil in the variator without removing the pan?

Yes, partial replacement is possible, but it is less effective. With this method, only ~50–60% of the oil is renewed, since some remains in the torque converter and channels. Partial replacement is recommended every 30,000 km, and full - once every 60,000 km.

What happens if you don’t change the oil in the variator?

Over time, the oil loses its properties: viscosity decreases, metal shavings accumulate, and deposits form. This leads to:

• 🔹 Belt slipping and jerking during acceleration.
• 🔹 Overheating of the variator (risk of hydraulic unit failure).
• 🔹 Accelerated wear of bearings and cones.

In critical cases, the variator can go into emergency mode or completely fail (repairs will cost 150,000–250,000 rubles).

How to check the oil level in the Qashqai J11 variator?

The level is checked at warmed up variator (oil temperature 50–60°C):

1. Place the car on a level surface.
2. Start the engine and let it run for 2-3 minutes.
3. Toggle the selector across all positions (P → R → N → D).
4. Remove the dipstick, wipe it, then reinsert and remove.
5. The level should be between the marks MIN And MAX.

Important: On a cold variator the level will be lower than real!

Do I need to change the filter every oil change?

The coarse filter (mesh in the pan) can be washed and reinstalled if it is not damaged. Fine filter (paper) It is recommended to change at every complete oil change., since it becomes clogged with small particles that are not visible to the naked eye.

Is it possible to mix NS-3 oil from different manufacturers?

Theoretically yes, if both oils are approved NS-3 and are produced by trusted brands (e.g. Idemitsu And Ravenol). However, it is better to use the same brand of oil to avoid possible chemical reactions. It is strictly forbidden to mix NS-3 with NS-2 or universal ATF!
