Consequences and symptoms of untimely replacement

If you do not change the oil on time, then serious problems with the quality operation of the variator cannot be avoided. The purpose of the lubricant is to lubricate the components of the box, and if it is not changed, the parts begin to rub against each other and their wear accelerates.

As a result, the transmission channels become clogged with metal shavings from the parts being ground in. This entails a drop in the pressure level in the variator, which subsequently negatively affects the functioning of the box as a whole.

Symptoms signaling the imminent failure of the variator:

• increasing the time period for warming up the box;
• drop in power plant power indicators;
• jerks and jolts when changing the position of the lever;
• drop in oil level.

Periodicity

According to the manufacturer's instructions, in Nissan Qashqai j11 CVTs and other Nissan models, replacement is recommended every 2 years or after 60 thousand vehicle mileage. For restyled cars of the same brand, this interval is increased to 90 thousand and three years, respectively.

However, in practice the situation is completely different: for long-term operation of the Nissan variator, a complete oil change is needed after 30-40 thousand mileage.

You need to take into account the conditions in which your car is used. Under increased loads, such as: strong temperature changes in summer and winter; bad roads; aggressive driving; the interval between oil changes is reduced. You can understand that another replacement is required by the following signs:

1. The variator jams;
2. Jerking when starting off;
3. The appearance of noise when moving;
4. Increased heating of the variator;
5. Noise in bearings;

You should immediately change the oil if any of these signs occur; as a rule, after the change they disappear, unless it breaks down.

Features of oil selection

Not only the correct operation of the variator, but also the overall performance of the crossover depends on whether the correct oil is selected for the automatic transmission. In order for a Nissan Qashqai with a CVT to please its owner for a long time, it is necessary to purchase exclusively products recommended by the manufacturer.

The best option would be Nissan CVT Fluid NS-2 oil. To change the oil in the variator, you need to stock up on two 4-liter cans of oil.

Which oil to choose for Nissan cars?

The original oil in the Nissan variator has the following markings: CVT NS-1, CVT NS-2, CVT NS-3. NS-1 is a first generation synthetic designed for Jatco continuously variable transmissions. It is poured into the boxes of Nissan cars produced before 2006 - Primera, Cube, March, etc.

NS-2 was developed for Hyper CVT gearboxes installed on cars after 2006 - Qashqai, X-Trail, Teana, Murano, Note, etc.

NS-3 will be required for 2012-2013 cars. release with continuously variable transmission. Used for the following Nissan models - Pathfinder, Teana, Serena, Altima.

Other manufacturers of CVT oil

Filling a Nissan CVT with non-original fluid is a risky undertaking. Incompatibility with factory lubricant, lack of necessary additives affects the service life of the box, and its repair is an expensive procedure. There are several analog options on sale that have proven themselves among Nissan car owners:

Idemitsu CVTF - designed for Jatco CVTs. In the list of relevant fluids, the manufacturer indicates the entire line of Nissan transmission fluids. Ravenol CVTF NS2/J1 Fluid is an oil of German origin, designed for use in JF010E and JF011E CVTs. A distinctive feature is green color. Nissan models for which the fluid is designed are Qashqai (Dualis), X-Trail, Serena, Lafesta. Febi Bilstein CVT is another German brand that is officially supplied to the Mercedes-Benz auto concern. The manufacturer claims the oil is compatible with original fluids for Nissan CVTs.

The process of changing the oil in Qashqai with a CVT

You can change the oil in a Qashqai with a CVT yourself. To do this, you need to go into the garage and turn off the engine. The driver has 15-20 minutes for all actions while the gearbox and engine are hot. To change the oil, you need to acquire the following tools:

• two 4-liter cans of oil;
• “flat” screwdriver;
• container into which the waste will be drained (volume no less than 3 liters);
• set of wrenches - wrenches and open-end wrenches;
• watering can;
• two or three clean rags or rags;
• rubber seal for the pallet;
• cleaning agent for the pan and filter (ordinary diesel fuel will do);
• coarse filter (if it is impossible to wash an already installed mesh).

Before starting this process, you must be very careful and strictly follow the following steps:

1. Install the SUV on the pit.

2. Remove the power plant protection.

3. Find the plug and place a waste container under it.

4. Unscrew the plug - a wrench will help.

5. Unscrew the screws that secure the pan and carefully remove it (waste oil may remain in it).

6. Inspect the magnets located inside the tray. If necessary, clean the products.

7. Remove and clean the filter mesh. If unsuccessful, replace with a new one.

8. Return the filter and magnets to their place. Replace the worn rubber pan seal using sealant.

9. Install the pallet and check that the bolts are securely fastened.

10. Pour oil into the variator using a watering can.

11. Drive a few meters (up to approximately 1 kilometer).

12. Measure the oil level and, if necessary, add to the mark.

Tools and consumables for replacement

If you are going to change the CVT oil yourself in the J10 and other Qashqai models, prepare the following tools:

1. Slotted screwdriver;
2. Pliers;
3. Socket wrenches or heads 10 and 19;
4. Open-end wrench “10”;
5. Funnel;

The materials you will need are:

1. Replacement fluid, from those described above in the “Oil selection” section;
2. CVT pan gasket;
3. Heat exchanger filter element;
4. Heat exchanger gasket;
5. CVT coarse filter Qashqai;
6. Drain plug gasket;
7. Spare drain plug, in case the thread of the main plug is damaged;
8. Containers for mining;
9. Clean rags;
10. Cleaner;

How to correctly measure the oil level in a Nissan Qashqai

1. If the car is cold. Start the car and let it run for 60-90 seconds. Turn off the car, remove the dipstick, wipe it, insert it again and now take it out and look. The level should be between the lower and middle “COLD” holes

2. If the car is warm (i.e. after a trip or turning on the cooling system fan 2 times.). Turn off the car, wait 60-90 seconds. Remove the dipstick, wipe it, insert it again, take it out and look. The level should be between the upper and middle “HOT” holes. As the car cools, the level will increase and again may rise above the upper mark.

For proper operation of the oil pressure pump, it is necessary to reset the fluid aging counter to zero! Since its performance is set by the ECU and as the oil wears out it changes. Therefore, if you do not have your own NISSAN CONSULT III or Launch X431 Diagun scanner, you will still have to contact a service station

The aging sensor is reset using ELM327 and CVTz50 in 3-5 seconds, or for 3000 rubles in the service

Checking the level

Checking the oil level and appearance can also help determine the need to change it. Therefore, you should check the level monthly. It is not difficult to check; all Nissan Qashqai CVTs have a dipstick. However, simply taking it out and checking the level is not enough; before checking the level, you should perform the following steps:

• Warm up the coolant of the car to 60-80 degrees, (indicator on the dashboard), if it is hotter, let it cool to the desired temperature;
• Roll the car onto a flat horizontal surface, do not turn off the engine;
• Depress the brake pedal. Then sequentially switch the selector with an interval of 5-10 seconds, through all possible positions;
• Switch the lever to “P” mode. Release the brake pedal.
• Find the filler neck (it may be marked CVT or Transmission);
• Unclip the latch and pull the dipstick out of the neck;
• Wipe the dipstick with a rag and return it to its place;
• Take the dipstick out again and see what mark the lubricant level is;
• The norm is considered to be the o level (“hot” or “full”);
• Replace the dipstick and secure it with the latch;

When your level is below normal, you need to look for and eliminate the cause - most likely there are leaks. If the lubricant is darkened or has a burning smell, it should be replaced immediately.

Metal particles in the lubricant visible on the dipstick indicate a problem with the radiator.

Detailed description of the procedure

1. The machine is placed on a flat area, above an inspection hole or on an overpass.
2. The bottom plug is unscrewed and all the oil is drained.
3. The pallet needs to be removed. To do this, unscrew the fasteners, and then you need to carefully pry it around the perimeter with a flat screwdriver, because the gasket often sticks. Reinstalling the pan can only be done using a torque wrench and replacing the gasket. The minimum tightening torque for the oil pan is 8 N/m, we advise you to increase it to 10-12 N/m in order to avoid sniveling.
4. It is necessary to dismantle the coarse filter. When dismantling, the main thing is not to lose the rubber seal. It must be purged under pressure using a special liquid or solvent.
5. There is a magnet on the oil pan to catch chips. Before and after cleaning it looks like this - fig. 1
6. It must be wiped with a dry cloth until it is completely clear of metal fragments.
7. It is necessary to change or blow out the filter of the Qashqai variator, fig. 2. It is pulled out of the socket with little effort. Purge is performed from a syringe using purified gasoline. To gain access to the fine filter, you need to remove the cover with four bolts - Fig. 3
8. Drain the oil from the radiator (Fig. 4.
9. Don't forget to reset the oil aging sensor.

When to change the oil in the variator

The oil in the variator of the Nissan Qashqai crossover should be changed every 40-50 thousand km. A more precise replacement period depends on road and climatic factors, driving habits and the cargo being transported, the volume of which should not exceed the permissible limit. For example, sudden starts and braking, driving in traffic light conditions, dusty and slushy areas - all this negatively affects the quality of the lubricant, which becomes unusable ahead of time. As a result, the replacement period must be halved, otherwise problems in the operation of the transmission may occur (jerking, jerking, humming and extraneous noise), and then technical problems up to a major overhaul or replacement of the gearbox.

What to do if the oil level is higher or lower than required?

If the oil level in the continuously variable transmission is below the permissible level, topping up will be required. In this case, only oil of equivalent characteristics is used. To test the product, you can mix a drop of old and new oils. Precipitation and a change in color indicate that the liquid selected for refilling cannot be used.

Excess oil can be pumped out through the dipstick hole.

Since overfilling is undesirable, it is necessary to check the dipstick when bringing the oil level to normal. If the level is higher than acceptable, pumping will be required. For this, a syringe with a rubber tube is used. The tip must be clean to prevent debris from getting into the box. Pumping is similarly controlled using a probe.

The Korean manufacturer's regulations state that the oil change in the Nissan Qashqai gearbox with a CVT must be done at least every 60 thousand kilometers. However, the Qashqai has an overly sensitive transmission.

It endures especially “painfully” poor-quality road surfaces, as well as off-road conditions. Such operating conditions negatively affect the condition of the mechanical transmission components and lead to their rapid wear. Therefore, owners of Kashkai cars with a CVT are advised to change the gearbox oil every 30 thousand.
