Changing the oil in the Nissan Murano Z52 CVT: A Complete Guide

Modern crossover Nissan Murano The third generation, known as the Z52, has a powerful engine and a smooth ride, but its heart—the continuously variable transmission (CVT)—requires special attention. CVTs of this model, although reliable, are extremely sensitive to the condition of the working fluid. Ignoring maintenance regulations can lead to expensive repairs or complete replacement of the unit.

Many owners are wondering: when and how to change the oil in the gearbox? The manufacturer often claims that the transmission is “maintenance-free,” but real operating experience in our conditions suggests the opposite. Regular changing the oil in the variator is the key to long life of your transmission Nissan Murano Z52.

In this article we will look at all the intricacies of the process, from choosing the right fluid to the nuances of checking the level. You'll learn why a partial replacement is often more effective than a full replacement, and what mistakes can cost you thousands of dollars.

Features of the Jatco JF016E variator on the Nissan Murano Z52

The heart of the transmission system in Nissan Murano Z52 favors CVT Jatco JF016E (also known as RE0F11A). This is an improved version of the unit that was installed on previous models, but it retains its general vulnerability to overheating and contamination. The main task of the transmission fluid here is not just lubrication, but the creation of hydraulic pressure for the operation of cones and pulleys.

During operation, the oil loses its properties faster than in classic automatic transmissions. High loads typical of a heavy crossover lead to oxidation of the fluid and the appearance of metal shavings. If you notice jerks during acceleration or extraneous noise, this may be the first sign that the oil can no longer cope with the load.

It is important to understand that the variator is Murano Z52 works in tandem with a cooling system. A clogged automatic transmission cooling radiator often causes overheating of the fluid, even with timely replacement. Therefore, checking the condition of the cooling system should go hand in hand with servicing the transmission.

Selecting transmission fluid and consumables

It is critical to use only the fluid recommended by the manufacturer. For Jatco JF016E series CVTs the standard is the specification NS-3. An attempt to fill with old NS-2 fluid or, even worse, automatic transmission fluid will lead to rapid failure of the clutches and valve body.

When choosing a brand, focus on the original from Nissan or proven analogues, such as Idemitsu or Shell, who are often official suppliers for the plant. Cheap substitutes may not withstand the temperature conditions of the variator at Murano Z52, which will cause the belt to slip.

• ✅ Original Nissan NS-3 — guarantee of compliance with all specifications.
• ✅ Coarse filter - must be changed with every oil change.
• ✅ Oil pan gasket - prevents leaks after draining.
• ✅ Copper drain plug washers are required for tightness.

The oil volume in the variator is about 8.5 liters with a full replacement, but with a normal partial replacement it will require about 4-5 liters. Don't skimp on quantity: if the system is not filled completely, it will cause cavitation and overheating of the pump.

⚠️ Attention: The use of NS-2 fluid in the JF016E variator is unacceptable! This will lead to changes in friction and rapid wear of metal components.

Tools and preparation for the replacement procedure

Before you get started, make sure you have the necessary set of tools. For Nissan Murano Z52 you will need a jack, car stands and a set of sockets. Pay special attention to the drain plug - it has a specific head, and if you try to unscrew it with the wrong tool, you will tear off the edges.

You will also need a container to drain used oil, a funnel to fill in new fluid, and a hose that fits over the dipstick or filler hole. Check the condition of the drain plug and replace the copper washer if necessary to avoid future leaks.

• ✅ Set of sockets and ratchet (14, 17, 19 mm).
• ✅ Container for draining waste (minimum 10 liters).
• ✅ Funnel with a long hose for pouring.
• ✅ Gloves and rags to protect hands and floor.

The car must be parked on a level surface. If you are performing the procedure in a garage, make sure there is sufficient lighting and access to the underside of the crossover. On Murano Z52, access to the variator pan may be difficult due to the engine protection, which will have to be removed.

Step-by-step instructions for a partial oil change

The replacement process begins with warming up the transmission. Start the engine and let it run for 10-15 minutes so that the oil becomes less viscous and drains more easily. After this, turn off the engine and place the car on jacks, providing safe access to the bottom.

First you need to drain the old oil through the drain hole. Be careful: the liquid may be hot. After the oil has completely drained, remove the oil pan. Inside you will see a coarse filter and magnets covered with metal shavings. This is normal, but they need to be cleaned thoroughly.

• ✅ Remove the crankcase protection and unscrew the drain plug.
• ✅ Remove the pan, drain the remaining oil and clean the magnets.
• ✅ Replace the coarse filter and pan gasket.
• ✅ Reinstall the pan with a new gasket.

After installing the pan, fill in new oil through the filler hole. Use a funnel and hose to get to the desired depth. Fill in about 4 liters of fluid, then start the engine and let it idle, switching the selector modes (P-R-N-D) for a few seconds in each position.

Checking the level and nuances of working with a variator

One of the most difficult parts of the procedure is checking the level correctly. On Nissan Murano Z52 does not have a classic feeler gauge for the CVT. The level is checked through the control hole in the pan with the engine running. The liquid should flow out in a thin stream and then turn into drops.

Oil temperature is critical for proper testing. The manufacturer recommends checking the level at a fluid temperature of 35 to 45 degrees Celsius. If the temperature is lower, the level will be too low, if higher, the level will be too high. Use a diagnostic scanner to accurately monitor your temperature.

⚠️ Warning: If you overfill the oil, it will cause the fluid to foam and lose pressure, which can destroy the variator. If you don’t fill enough, the unit will overheat.

After checking the level, tighten the control plug with a new copper washer. Make sure it is tightened to the correct torque to avoid leakage or damage to the threads. At this point, the replacement process can be considered complete, but it is recommended to drive a short distance and check the level again.

What to do if the level does not level out?

If the level does not stabilize after several check cycles, there may be an air lock in the system. Try accelerating the engine and changing gears again. If the problem persists, contact a specialist to diagnose the valve body.

Partial or complete replacement: what to choose?

There are two main methods for changing the oil: partial (gravity) and machine (pressure). For Nissan Murano Z52 experts often recommend a partial replacement, especially if the car's mileage exceeds 100,000 km and the oil has never been changed.

Hardware replacement washes out up to 95% of the old oil, but it can also wash dirt out of the valve body and clog the channels. In a worn variator, old oil often serves as a kind of “sealant” for worn clutches. A sudden change to clean oil can cause the box to start slipping.

• ✅ Partial replacement: safe for old units, changes 30-40% of the volume.
• ✅ Complete replacement: effective for new cars with mileage up to 80,000 km.
• ✅ Double partial replacement: carried out at intervals of 500-1000 km for deep cleaning.

If you decide to carry out a complete replacement, make sure that the variator is in perfect condition. Otherwise, it is better to limit yourself to partial replacement, repeating the procedure every 10-15 thousand kilometers. This will allow you to gradually update the fluid without risk to the unit.

Typical mistakes when servicing transmissions

One of the most common mistakes is ignoring the condition of the coarse filter. Some owners simply wash out the old filter and put it back. This is unacceptable: the filter becomes clogged with wear products and stops passing oil, which leads to oil starvation.

Another mistake is using the wrong gaskets. Cheap gaskets may not withstand oil pressure and begin to leak after just a few thousand kilometers. Always use original parts or high-quality analogues from trusted brands, such as Viktor Reinz or Elring.

⚠️ Caution: Never overtighten the oil pan bolts. This can deform the pan and lead to difficulties during the next replacement.

Also, do not forget about washing the magnets at the bottom of the pan. They collect metal shavings, which are an indicator of the condition of the unit. If there are a lot of large chips or “crumbs” on the magnets, this is a signal that serious wear processes are occurring inside the variator.

How much oil is needed and table of regulations

For proper replacement planning, it is important to know the exact volumes and intervals. Below is a table with basic data for Nissan Murano Z52. These numbers will help you calculate the required amount of supplies and plan your budget.

Parameter	Meaning	Note
Total system volume	8.5 liters	With a complete replacement with flushing
Volume for partial replacement	4.0 - 4.5 liters	Gravity drain
Replacement interval	60,000 km	Recommended by factory
Real interval	40,000 km	For city conditions and mileage
Liquid type	NS-3	Strictly according to specification

Remember that the actual replacement interval depends on your driving style. If you like dynamic driving or often tow a trailer, reduce the replacement interval to 30-40 thousand kilometers. This will significantly extend the life of your Nissan Murano Z52.

FAQ: Answers to frequently asked questions

Is it possible to change the oil in a variator yourself?

Yes, you can do this yourself if you have a garage, a lift or jacks, and a minimum set of tools. However, checking the level requires precise control of oil temperature, which can be difficult without a diagnostic scanner.

How often do you need to change the oil in the Nissan Murano Z52 CVT?

The official regulations indicate 60,000 km, but for Russian conditions it is recommended to change the oil every 40,000 km with a partial change. This will ensure maximum reliability of the unit.

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

The oil loses its properties, begins to oxidize and become contaminated with wear products. This leads to overheating, belt slipping, jerking and, ultimately, the need for expensive repairs or replacement of the variator.

Is it necessary to warm up the variator before changing the oil?

Yes, the engine must be warmed up to operating temperature so that the oil becomes less viscous and drains better. However, when checking the level, the temperature should be in the range of 35-45 degrees, so after draining and filling, allow the engine to cool slightly.

Can I use NS-2 fluid instead of NS-3?

Absolutely not. NS-2 fluid has different physical properties and is intended for other CVT models. Using NS-2 in the JF016E will cause the transmission to fail quickly.
