What kind of oil to pour into the Nissan Qashqai variator. Maintenance of the variator on the Nissan Qashqai crossover

Not so long ago, newly produced cars began to be equipped with completely new types of transmission - CVTs. The name comes from the English phrase Continuously Variable Transmission, which means “constantly variable transmission”.

Often this type of gearbox is called by the abbreviation of the name in English - CVT. The very concept of this technical solution is not new and has been used on some types of equipment for a long time.

The technology of stepless speed control received mass distribution only when it was possible to achieve an acceptable service life of the CVT transmission.

The car, in addition to the standard machine, was also equipped with a CVT gearbox. In the material of the article, we will consider in detail the procedure for changing the oil in the variator of a Nissan Qashqai car.

Features of the variator

The CVT-type gearbox is fundamentally different from all analogues known today. The technology of stepless regulation itself has been known since the boom of small-displacement scooters.

But in the case of the scooter, the infinitely variable mechanism was fairly easy to make reliable. The method of increasing the margin of safety due to the massiveness of the knot was used. And the torque that the variator on the scooter passed through itself was negligible.

How the variator works - video

In the case of the automobile, the slowdown in the adoption of this technology was partly due to the difficulties in creating a reliable and durable prototype of the CVT box. No one will buy a car in which the transmission resource barely reaches 100 thousand kilometers.

Today this problem is solved. CVT-boxes without problems work out no less than their automatic opponents, built according to the classical scheme. But here a very important condition is timely service. Namely, the replacement of transmission oil and filters.

In the Nissan Qashqai CVT, torque is transmitted through a metal belt stretched between two pulleys. The pulleys have movable walls, controlled by hydraulics, which can diverge and shift. Due to this, the radius of these pulleys changes, and, accordingly, the gear ratio.

The hydraulic system in the Nissan Qashqai variator is controlled through a valve body, which is controlled by a computer. Fluid flows are distributed throughout the system by opening and closing valves actuated by solenoids.

Why is it necessary to change the oil in the variator

If we compare all types of transmission common today, then the variator will be the most demanding on lubrication. Let's take a look at the reasons for this demand.


A metal belt stretched between two pulleys perceives and transmits enormous loads for such a small element. The contact of the side surface of the plates that make up the belt with the working surface of the pulley occurs with a very large clamping force.

This is necessary so that the belt does not slip and does not bully the surface of the pulley. Therefore, an oil layer must be present in the contact patch. Such operating conditions lead to intense heating. And with a drop in the quality or level of oil in the variator, the box overheats quite quickly.

Qashqai variator without protective cover

The second important factor is the nature of the operation of the control valve body. To close the clutch packs in a classical automaton, only the very fact of creating an effort at the right moment is required.

And for the normal operation of the pulleys, the speed and exact observance of the moment of fluid supply to the cavity under the movable pulley plate is important.

If the moment of applying the force and its magnitude is not observed, then the belt may slip due to loosening of the tightness or, conversely, an excessively high tension, which also has a bad effect on the durability of the variator.

What is required to replace

Changing the oil in a Nissan Qashqai variator is a simple operation from a technological point of view. But it requires a careful and thoughtful approach. Before starting work, it is advisable to immediately stock up on everything you need.

So, to independently replace the working fluid, you will need the following:

• 8 liters of genuine NISSAN CVT Fluid NS-2 gear oil (sold in 4 liter cans, purchase code KLE52-00004);
• pallet lining;
• fine oil filter;
• coarse oil filter (mesh);
• rubber sealing ring in the heat exchanger;
• copper sealing ring under the drain plug;
• an empty plastic container with a volume of at least 8 liters, preferably with a graduated scale to assess the amount of drained oil;
• carburetor cleaner or any other process fluid intended for degreasing surfaces (preferably highly evaporating);
• a set of wrenches (preferably with heads, so the replacement process will be faster), pliers, a screwdriver;
• clean rags from which the pile or single threads do not separate (a small piece of soft flannel fabric will do);
• watering can for pouring new oil.

To change the oil in the Nissan Qashqai variator, you will need an inspection hole or a lift. It is more convenient to carry out work from the inspection hole, since during the replacement process it will be necessary to carry out manipulations in the engine compartment.

The procedure for changing the oil in the Nissan Qashqai CVT

Before starting the replacement, it is recommended to warm up the fluid in the variator to operating temperature. To do this, depending on the season, you need to drive 10-15 km or let the car idle for 15-20 minutes. Thanks to the heat exchanger, the oil in the variator warms up even without load.

After placing the car on a viewing hole or lift, the pan is cleaned of adhering dirt. Carefully remove the drain bolt. An empty container is substituted.

1. The bolt is unscrewed to the end, and the spent fluid is drained. You need to wait until the jet of oil turns into drops. After that, the cork is wrapped back into the hole.
   
2. Carefully break off and unscrew the bolts securing the pallet. The pallet is carefully separated from the box. There is still some oil left in it. This oil is also sent to a waste tank.
3. The bolts securing the coarse filter are unscrewed. The mesh is carefully removed.

   Important! Be careful not to lose the o-ring. It doesn't always come with a new filter.

   Some car owners wash the mesh on the old filter, thereby saving several hundred rubles. But washing it completely will not work, since fine chips are firmly clogged between layers of mesh material. Therefore, saving on this element is a very dubious occupation.
   

4. A new coarse filter is installed.
5. The tray and two magnets are cleaned of sediment and small chips. At this stage, it is important to pay attention to the amount and structure of the chips.
   Sometimes it is in the process of changing the oil that it is possible to detect and eliminate serious malfunctions in the operation of the variator before the limit state occurs. Additionally, the pallet geometry is checked and the contact surfaces for the gasket are cleaned.
6. The front left wheel is removed.
7. The air duct, the plastic protection of the left front arch, the battery and the stand under it for access to the heat exchanger are dismantled.
8. The hoses for supplying antifreeze and gear oil are carefully disconnected. Openings can be plugged with clean rags or other available means.
9. The heat exchanger is disassembled and the fine filter is changed.
   
10. A new o-ring is installed in the housing. The heat exchanger is assembled in reverse order. The dismantled parts are installed in their places.
11. The pallet is installed in its place. When tightening its fasteners, it is important to remember that the crankcase of the CVT box is made of aluminum alloy, the bolt thread diameter and its length are small. Therefore, it is impossible to apply excessive force when tightening the bolts. You can turn the thread. If you have a torque wrench, it is better to use it. The tightening torque is 30 Nm.
12. A new copper ring is placed under the drain plug. The cork is twisted into a pallet.
13. New oil is poured through the dipstick channel in an amount approximately equal to the drained one. The level is checked. Fluid is added to the COLD mark on the dipstick.
14. The engine starts and at idle the oil warms up to operating temperature. The level is checked again. It should be at the HOT mark. In case of abundance, topping up is performed.

This completes the oil change procedure in the Nissan Qashqai variator.

Conclusion
As can be seen from the instructions for changing the oil in the CVT box of the car in question, there is nothing complicated about this. You just need to carefully and sequentially follow the instructions. Change the oil more often than the scheduled period - and the variator will serve for a long time and without fail.

- the procedure is standard, but painstaking. You can make it in two ways, the first is to take the car to the service, the second is with your own hands.

Automatic transmissions with a CVT are quite common among Nissan cars. Such an automatic transmission is reliable and, with proper care, has a long service life. To avoid problems in the gearbox, it is necessary that the lubricant in the Nissan Qashqai variator be changed on time. Checking the fluid level should be done at least as often as on any other vehicles. If you see that the color of the oil has become too dark and an unpleasant smell has appeared, then this indicates that a complete and immediate oil change is necessary.

The probe in the variator, with which the replacement is carried out

Due to a malfunctioning filter, friction powder and metal chips may enter the variator. Such a process will impede the operation of the solenoid valves, which is why it is so important that the replacement be carried out in a timely manner. Also, a timely replacement prevents the oil pump valve from jamming. Changing the lubricant in the Nissan Qashqai automatic transmission variator should occur after every 30,000 km. Before each such procedure, it is necessary to lower the probe for. Today we will tell you how to replace the fluid in the Nissan Qashqai automatic transmission with your own hands. We will show how to check the level and share our experience on how to give your car a long service life.

What kind of oil is required and in what quantity

The quality of your Nissan Qashqai automatic transmission depends on the right transmission fluid. And the correct amount of slurry filled in indicates further consequences. Therefore, it is recommended to fill the variator with NISSAN CVT Fluid NS-2 oil (it has the original code KLE52-00004). You will need 2 canisters (each with a capacity of 4 liters). Remember that before starting the procedure and after its completion, it is necessary to check the level in the gearbox. The transmission fluid must be at least the “min” mark and not more than the “max” mark.

Tools

• New pallet lining in the variator (for those who, along with this procedure, want to change the lining);
• Key for 10;
• Open-end wrench or head;
• Slotted screwdriver;
• Drain container;
• Clean rag;
• Funnel;
• New lubricant.

Replacement instructions

1. As we wrote earlier, you will need 2 cans of 4 liters of lubricant, which you need to acquire in advance. Also decide in advance whether you will change the pallet. So what do we do:
2. Install the Nissan Qashqai car over the pit or on a lift.
3. Before replacement is carried out, remove the crankcase protection. (for this you will have to refer to the manufacturer's instructions) Or you can try to remove the factory shield from the back.
4. Next, unscrew the 2 bolts that are located on the sides and are attached in front to the subframe. Unscrew the bolts with an open-end wrench or head.
5. Now you need to pull out 4 pistons (on the sides) and 1 (in front). How it's done? You need to pry off the part of the piston, which is located in the center and pull it down by 8 mm, so they will be easier to remove.
6. When the entrance to the engine compartment has opened, you can proceed directly to this procedure. Check the level before starting. You can check the level by pulling the dipstick.
7. Then, after confirming the need for replacement, warm up your engine by shifting gears 1-2. It is possible to pour lubricant into the variator and generally proceed with such a procedure only if the engine is warmed up. Warm up for 5 minutes, and then remove from all gears.
8. To remove the probe from the pipe, you need to press the locking tab with a slotted screwdriver, and then pull it up. By the way, in a warm engine, the lubrication level is always higher.
9. After checking and warming up, you can install a drain container under the variator and actually drain the old consistency. It is better to know the volume that will pour out, because then it will be easier to navigate when pouring. Draining will take you 20-25 minutes.
10. If you still decide to change the pan, then you will need to unscrew it after draining, it is held on by 18 bolts. Remember that grease has also likely leaked into the pan, so be careful when removing it, it will immediately pour out.
11. There are 2 magnets on the pallet, so you need to wipe them with a clean cloth, remove all plaque. This is done in order to avoid getting debris inside.
12. Well, the last thing left is to fill in the new transmission fluid using a funnel. After filling, it is necessary to check the level again, you can preheat the engine.

This completes the operation. Good luck.

If the article helped you change the Nissan Qashqai, then do not forget to leave your feedback on our website.

Crossovers are a popular class of cars in Russia. This is explained by their improved cross-country ability. Given the quality of Russian roads, this is a weighty argument. Among this group of cars, the latest generation Nissan Qashqai, released in 2014, stands out. The relatively inexpensive cost and availability of this car is explained by the fact that it is assembled at Russian factories.

Brief autobiography of Qashqai

Nissan Qashqai appeared on the automotive market by the end of 2006. In the English city of Sunderland, at the Nissan plant, they began to produce it for the European market. In Japan and North America, this car is sold under different names. His concept was so successful that the Nissan Qashqai became the founder of a new class of compact crossovers.

The last, second, generation of cars was introduced by the end of 2013. Already in 2014, cars began to roll off the assembly line of the English plant. A little later, by the first half of 2015, the assembly of cars was launched at a plant near St. Petersburg, which began its work in 2009. Thus, Russian motorists can buy a 2013 Nissan Qashqai on the market, produced in Russia, England or Japan. Russian cars occupy a third of all offers. But it is immediately worth noting that a foreign-assembled car is more expensive due to customs duties.

Complete sets of the Russian assembly are offered with three models of engines - two petrol volumes of 1.2 and 2.0 liters, with a capacity of 115 and 144 hp. with, as well as with a diesel engine with a capacity of 130 horses. Its volume is 1.6 liters. You can choose front or all-wheel drive. There are options with a manual transmission (1.2 and 2.0 liters) or a variator (CVT).

Features of the CVT

This transmission is not common in cars traveling on Russian roads. This is explained by the fact that everything new is perceived with caution and ambiguous. And the principle of operation of the variator in the Nissan Qashqai, as well as in other car models, is really new. The gear ratio from the engine to the wheels changes smoothly, and not in steps, as in all other gearboxes.

It's pretty simple: the CVT has two tapered pulleys - a drive and a slave. The pulley cones can converge and diverge, thus changing their working diameters. The pulleys are interconnected by a metal wedge-shaped belt capable of changing the geometry of its section. The principle is similar to gear shifting on a sports bike. Only instead of pulleys, the design of the bicycle has a driving and driven sprockets. How the variator works - clearly and without comment, can be seen in the figure.

Advantages and disadvantages

The advantages of CVT transmissions include the fact that the car picks up speed very smoothly. Jerks and shocks during normal operation of the CVT are absent. Acceleration is as fast as with a manual transmission. There is no loss of power and increased consumption, unlike automatic transmissions. If you follow the operating rules and change the oil regularly, the variator will serve without repair for a very long time. Nissan gives a guarantee for CVT manufactured by the Japanese company Jatco - 100 thousand kilometers. In reality, subject to proper operation, the declared resource is 200 thousand kilometers.

At the same time, the Nissan Qashqai 2013 variator has disadvantages in the form of restrictions and operating rules:

Main malfunctions

Unfortunately, the manufacturer's warranty does not protect the Nissan Qashqai 2013 transmission from damage. He has his weaknesses, which appear after a significant run. Many car owners note that after a run of 50–60 thousand km, problems appear in the operation of the microswitches. As a result, they need to be replaced. The malfunction manifests itself in the fact that it is impossible to change the operating modes of the variator - for example, remove it from the parking lot.

The metal strap is also the weak point of the box. If you drive too aggressively, it may need to be replaced. Symptoms of malfunctions are manifested in the fact that the Nissan Qashqai begins to behave unnaturally:

If such symptoms appear in the Nissan Qashqai 2013, you should immediately contact the dealer or a trusted service station for diagnosis and subsequent repair.

How to change gear lubricant

During operation, the Nissan Qashqai requires a periodic oil change in the variator of the 2013 model. Replacement, according to the regulations, should be done every 60 thousand km. But for Russian operating conditions, it is better to do this after 30-40 thousand km - then the Qashqai variator will last a long time.

For this purpose, it is required to purchase Nissan CVT Fluid NS-2 transmission oil. Its original code is KLE52-00004. To completely replace it in the box, you will need 2 canisters with a capacity of 4 liters each. In addition, you will need to purchase:

• oil filter, which will need to be changed in the heat exchanger;
• new CVT crankcase gasket;
• sealing ring for drain plug;
• coarse mesh filter (in case you cannot wash the old one).

From tools and improvised means you will need:

• ring wrench for 10;
• funnel for draining oil;
• capacity for old grease with a volume of at least 8 liters;
• liquids for washing the pan and filter (carburetor cleaner and diesel fuel);
• rag.

The replacement of transmission oil in a 2014 Nissan Qashqai car must be carried out in a certain sequence.

1. It is required to warm up the transmission, and then drive into the inspection hole or overpass. Can be used to replace the lift. If there is engine protection, you will have to remove it.
2. You need to find the CVT oil dipstick and check the oil level in order to know to what level it will need to be filled. It should be near the "HOT" (hot) mark.
3. The drain plug from the CVT pan is carefully unscrewed with a 10 wrench. First you need to prepare a container for draining mining. Be careful not to burn your fingers - the grease is hot. It is important not to confuse the CVT sump with the engine sump.
4. The oil is drained until it completely stops flowing. We'll have to wait a while.
5. The CVT pan is being dismantled, and after it, the coarse filter. For this, a key of 10 is used. You need to keep a container nearby - a little more grease will merge.
6. The crankcase of the box and the magnets on it, as well as the filter, are cleaned of dirt and metal particles with diesel fuel and a carburetor cleaner. If the filter does not wash off, you will have to replace it with a new one.
7. The filter is installed in its place. The pallet with a new gasket also needs to be installed back. The drain plug with a new copper gasket is screwed on.

Next, the fine filter is replaced. To replace it, you will have to remove the air duct and battery under the hood, unscrew the bolts securing the platform under the air duct. Before that, remove the left wheel and partially unscrew the fender liner.

Getting to the heat exchanger will be quite difficult. It should be remembered that oil flows through thin pipes of the oil cooler, and antifreeze flows through thick pipes. The oil cooler is unscrewed and the filter located inside is changed.

Finally, all parts and pipes are installed in place. New oil is poured through the funnel into the dipstick hole. Usually it takes from 7 to 7.5 liters of lubricant. Periodically check the oil level with a dipstick. Then you need to warm up the engine and transmission well and add lubricant if necessary. This completes the procedure for replacing the transmission fluid in a 2013 Nissan Qashqai car.

One of the important conditions for the trouble-free operation of the Nissan Qashqai variator with a 2.0 liter engine is the timely replacement of oil in it. This procedure is not too complicated, but rather painstaking. You can perform it yourself, but if the driver is afraid of “doing something wrong”, then it is better for him to seek help from a specialist.

Automatic transmissions with a CVT in the Nissan car family are not uncommon. They are highly reliable and durable, of course, subject to the rules of operation. The fluid level in this mechanism must be carried out at the intervals established by the manufacturer, as in any other machine.

The need for an urgent oil change in the variator is indicated by an unpleasant odor coming from the liquid, as well as its darkening. Before proceeding with the replacement, you need to purchase exactly the oil that should be used in the variator mechanism, since the correct operation of the gearbox largely depends on this. In addition to choosing the right brand, it is also important to know the amount of transmission fluid that will be needed for replacement.

The oil used in the variator of this car is produced by the NISSAN automobile concern and has the CVT Fluid NS-2 brand. The original code for this fluid is KLE52-00004.

To change the oil, you will need to purchase two 4-liter cans of new transmission fluid. Immediately before starting work, as well as after its completion, it is necessary to check the amount of oil in the gearbox (the level must be within two marks on the dipstick - “MIN” and “MAX”).

Necessary tools and materials

To perform the work, you will need a wrench "10" socket or ring type, an open-end wrench (you can use a head instead), as well as a flat-tip screwdriver. In addition, you need to stock up on a container into which the waste liquid will be drained, clean rags, new oil in the amount of 8 liters and a funnel for pouring it into the system. If there is a need to replace the lining of the pallet, then you need to purchase a new lining.

Operating procedure

Having prepared a new transmission fluid, and, if necessary, a new pan, you can get to work. For this, the car will need to be driven into a viewing hole or hung out using a special lift. A car overpass will also work.

First of all, it will be necessary to dismantle the crankcase protection (this procedure is described in detail in the operational documentation). If this seems too inconvenient, you can try to dismantle the factory shield, which is located on the back of the car.

After that, using an open-end wrench (special head), you need to unscrew a couple of bolts on the sides that are fixed to the subframe.

The next step is to pull out five caps, one of which is located in front, and four on the sides. To do this, you need to pry up the central part, and then pull it down 8 millimeters - this will make it easier to remove.

After that, access to the compartment of the power unit opens, which allows you to proceed directly to the replacement. Before that, as mentioned above, it is necessary to check the level and condition of the transmission fluid contained in the system by pulling out the dipstick.

If replacement is really necessary, the engine should be warmed up for 5-7 minutes, shifting gears alternately to positions 1 and 2 - this is necessary to complete the operation. After warming up, the transmission lever should be in neutral position.

The probe can be pulled out of the tube with a flat-tip screwdriver. She should press on the stopper tab, and then pull the probe up. It should be borne in mind that the oil level inside a warm engine is always higher than inside a cold one.

After the oil level is checked and the engine warmed up, the container into which the old fluid will be drained should be installed under the lower part of the variator. Then, removing the hole plug, drain the used oil. It is advisable to measure the volume of the drained liquid - this will help you navigate when filling in a new one.

If there is a need to replace the pan, then after draining the old oil, you need to remove it by unscrewing the 18 fixing bolts with which it is held in place. In this case, care should be taken so as not to pour over mining, which in most cases flows into the pan.

A couple of magnets on the pallet should be carefully wiped with a clean rag, otherwise, when installing a new lining, debris from them will enter the system.

After that, remove the coarse filter

After that, all removed parts must be thoroughly washed - diesel fuel is suitable for this purpose. Disassembly of the filter in most cases is not required, its mesh is washed without much difficulty.

Here's what a well-cleaned and washed pan looks like:

Then a new copper washer must be installed on the gearbox drain plug.

The last thing left to do is insert a funnel into the filler neck, and then pour new gear oil into the variator system.

After the oil has been filled, start the engine again and warm it up for a few minutes, and then check the oil level.

This completes the operation.

Photo report on oil change in the variator car will help you cope with this procedure on your own.

If you refer to the maintenance schedule, the oil change in the Qashqai J10 2.0 variator must be carried out through every 60 thousand kilometers, and given the state of domestic roads - better every 30. In restyled models (Qashqai 1.6 CVT), this regulation was extended to 90 thousand. Also note that the variator requires not the usual ATF like an automatic machine, but NISSAN CVT Fluid NS-2 or NS-3 (KLE5300004) if the box is RE0F10E, JF016E / JF017E (CVT8/TN). For a complete replacement, two 4-liter canisters will be required, although 7.5 liters will enter the box, and if you do not remove the tubes from the radiator and do not drain from there, then less. But if you change, then do it as expected, and with washing the valve body (if the box twitches), magnets, pallet.

Perhaps someone will start a discussion about this, however, to change or not is everyone's business. The oil change procedure is simple, and as you can see on the slides, you can do it yourself, but it is unlikely that you will be able to follow all the recommendations. Ideally, at the service, the Nissan Qashqai variator fluid is replaced by removing the pan and oil cooling radiator, cleaning the magnets, washing the iron filter, and with every third replacement it is also worth changing the paper one (fine cleaning is in the heat exchanger) and the iron filter (coarse mesh filter cleaning) and resetting the CVT fluid degradation level registered in the ECU (oil pressure depends on this).

Changing the oil in the variator must be done when the engine and gearbox are warm. And also do not forget to change the sealing washer of the drain bolt and change the oil filter.

The Nissan Qashqai CVT fluid replacement procedure requires the following tools and materials:

• socket wrench to "10" (or head) and to "19" (unscrew the drain plug);
• flat screwdriver;
• oil drain container;
• cleaner;
• clean rag.

Naturally available to have:

• fresh liquid (original code KLE5200004);
• pan gasket orig. nom. 31397-1XF0C aka MITSUBISHI 2705A015;
• sealing washer (NO. NISSAN 11026-01M02);
• a new paper filter cassette for the heat exchanger (original NISSAN 317261XF00 or MITSUBISHI 2824A006), and if the variator filter (coarse cleaning) is heavily clogged, then it will also be needed, its orig. number NISSAN 317281XZ0D or MITSUBISHI 2824A007;
• oil cooler housing gasket (MITUBISHI ref. 2920A096)
• funnel.

As the oil change procedure in the Qashqai variator is completed, it is recommended that the scanner reset the oil aging counter.

With self-replacement, no matter how much oil is inside 8-9 liters (front-wheel drive), only 2/3 is drained, so that a third of the old oil is mixed with the new one, which naturally reduces its further service life. That is why it is recommended to change the oil in the variator on the Nissan Qashqai more often than on.

To change the oil in the CVT, you need CVT oil NISSAN CVT Fluid NS-2, original code KLE52-00004. You will need to purchase 2 cans of 4 liters.

Since changing the variator oil is recommended not only with removing the sump and cleaning the magnets, but also with changing the filter, it is recommended to purchase both a new NISSAN GASKET OIL-PAN variator sump gasket with the original number 31397-1XF0C and also a brand of small things ...

O-ring for oil filter in cooler

Drain plug gasket and oil cooler filter for the Qashqai variator.

Before changing the oil in the variator, it is necessary to remove the crankcase / gearbox protection according to the manufacturer's instructions or remove the back of the nameplate. Dismantling is carried out on a pit, overpass or lift.

To do this, unscrew the 2 x 10 bolts on the sides of the attachment to the front of the subframe and remove 4 clips from the side parts and 1 clip from the front of the subframe.

To remove the pistons, hook the central part of the piston and pull it down about 8 mm. After that, the piston is easily removed from the hole.

It is convenient to unscrew the bolts with a head, because. they are recessed inside the shield. But you can get by with an ordinary open-end wrench.

When access to the engine compartment is open, you can proceed to the direct procedure for changing the oil.

Changing the oil in the variator must be done on a warm engine and gearbox. Before you start draining the oil, you need to remove the CVT dipstick and check the level.

To remove the probe from the seat on the tube, use a slotted screwdriver to press the locking tab and pull the probe up.

On a warm box, the oil level will be higher than the marks on the dipstick and tend to the inscription > HOT<.

The drain plug of the Qashqai variator pan is unscrewed with a key to “19”. By the way, when it is reversed, it is recommended to tighten it with a torque wrench with a force of 35 Nm. Since there is a copper sealing washer under it, and the delicate thread there can be torn off, then you will also have to run for a new bolt (No. 3137731X06)

Old and new washers for the drain bolt. Be sure to change with every fluid change.

It must be remembered that it is better to know how much oil has drained from the box, so that it is easier to navigate when filling. Oil can drain from the box up to 20-25 minutes.

As soon as it stops dripping from the drain hole, you can unscrew the pan itself. Fastening bolts, all 18 pieces, unscrew the head to "10". When removing, be careful, because there will still be oil (due to the design features), so it’s better to unscrew and leave a few bolts on one side so that all that liquid does not pour out.

This is what the Qashqai variator looks like with the pallet removed. The picture opens onto the valve body and the coarse filter in it, which must be cleaned of chips, and if it is very dirty, then it’s better to change it because the variator, like no other box, is VERY afraid of chips. Therefore, we will continue to remove the same mesh filter ...

The filter is also unscrewed with a 10 head.

On this slide, you can see all the dirt and chips that settled on the grid and did not get into the valve body solenoids.

There are 2 magnets on the tray. All plaque from them must be removed and the pan wiped clean with a lint-free rag so that no debris gets into the variator. It is important!

This is what the magnets look like before cleaning from chips.

And here it is after cleaning...

so we clean the tray itself with high quality.

When reinstalling an old or new coarse filter, do not lose this sealing ring, many people forget about it and then the filter does not let dirt through tightly. Next, screwing the pan to get to the fine filter....

To get the filter out of the heat exchanger, it’s not an easy job to do, you will need to dismantle the air duct, battery, unscrew and put aside the “brains”.

It is unlikely that it will be possible to dismantle the platform that will interfere, but in principle you can do it this way, you can easily get it by hand, if you can remove the wheel and bend the fender liner and turn it from below, but I don’t think it will come to that.

By the way, look there, do not confuse the hoses, suddenly you will be removed ... otherwise, instead of the varicose fluid, you will also start draining the antifreeze.

Unscrew the oil cooler to get the fine filter. There are 4 turnkey bolts on "10"
