The electrode of the original iridium plug should have such a soldering

Compliance with the factory regulations for replacing spark plugs will not reduce possible equipment failure, and will also ensure correct ignition of the air-fuel mixture. For Nissan with gasoline 1.6 and 2.0 liters, the manufacturer recommends replacing the spark plugs every 30,000 km or every two years. Experience shows that the Nissan Qashqai candles installed at the factory can run up to 60,000 kilometers. Signs of incorrect operation are manifested in the following:

• deterioration in vehicle dynamics;
• prolonged engine start;
• motor troit;
• interruptions in the operation of the internal combustion engine;
• increase in gasoline consumption.

It is not easy to distinguish a fake by packaging

If these problems appear, replace the spark plugs. Provided that the malfunctions are not caused by problems in other parts of the motor. In this case, all Nissan spark plugs should be replaced at once, both during the next and unscheduled replacement.

Which candles to choose for Nissan Qashqai?

Spark plugs with the following characteristics are used on Nissan:

• thread length - 26.5 mm;
• heat rating - 6;
• thread diameter - 12 mm.

Devices with platinum or iridium electrodes have a longer resource. From the factory, spark plugs from NGK with the article number 22401-SK81V are used. It is recommended to use Denso (22401-JD01B) or Denso FXE20HR11 products equipped with an iridium electrode as the main analog version prescribed by the factory instructions.

When buying an original plug for Nissan powertrains, it is easy to run into a fake.

NGK offers an analogue of a factory product, but with a significant difference in cost - NGK5118 (PLZKAR6A-11).

You can also use the following options:

• bosch products with a platinum electrode - 0242135524;
• Champion OE207 - electrode material - platinum;
• Denso Iridium Tough VFXEH20 - These products use a combination of platinum and iridium for electrodes;
• Beru Z325 with platinum electrode.

Tools for self-replacement candles and features of the procedure

Dismantle the decorative cover, remove the branch pipe

You can change the candles for Nissan Qashqai on your own, while you need to dismantle a number of nodes. To do this, you will need to prepare the following tools and materials:

• spanners and socket heads for 8, 10 with ratchet and extension;
• flat-blade screwdriver;
• candle wrench for 14;
• torque wrench;
• new spark plugs;
• throttle assembly and intake manifold gasket;
• clean rags.

For the convenience of replacing with a Nissan, it is better to use a spark plug wrench with a magnet. If not available, ignition coils can be used to remove and install the spark plugs. It is recommended to replace the elements one by one. This will minimize the likelihood of foreign objects entering the cylinders.

Unscrew the manifold mounting bolts, disconnect the connector from the purge valve, unscrew the throttle

The use of a torque wrench is necessary to withstand the tightening torque of the spark plugs, throttle body and intake manifold fasteners. If the permissible forces are exceeded, destruction of the plastic or the cylinder head can occur.

A detailed description of changing candles Nissan Qashqai do it yourself

If the replacement of the candles is done on our own, it is recommended to use the camera for step-by-step recording of actions. This will simplify the process of reassembling previously dismantled units from the power unit.

Replacing the ignition elements for a Nissan 1.6 and 2 liters is carried out in the same way, regardless of the generation of the car.

Replacement process

• Before starting work, it is necessary to allow the power unit to cool;
• We dismantle the decorative plastic cover fixed with two bolts;
• Next, the air duct is removed, which is mounted between the air filter housing and the throttle assembly. To do this, the clamps are loosened on both sides that hold the air filter and crankcase ventilation pipes;
• The next stage is the dismantling of the remote control. To do this, unscrew the fixing bolts in the amount of four pieces, one of them is located directly under the damper. In the future, the entire unit is retracted to the side, without disconnecting the supply wires and the cooling system;
• We remove the oil dipstick from the seat, covering the hole with a rag. This will avoid getting debris into the;

It is better to cover the openings of the block head with something, remove the coils, remove the candles, put new ones, tightening with a torque wrench

• The intake manifold is dismantled, which is fixed with seven bolts. It is recommended to start by unscrewing the central bolt located on the front of the manifold, followed by unscrewing four more fasteners. The back of the plastic is secured with two bolts. One is located in the place of installation of the throttle unit, and the second is on the left side and is fixed through the bracket. After removing all the fasteners, the intake manifold is gently lifted up and out to the side without disconnecting the pipes;
• The installation site of the intake manifold is carefully wiped from dirt and dust, with holes in the cylinder head previously covered with rags;
• Further, the supply wires are disconnected and the fastening bolts of the ignition coils are unscrewed, which makes it possible to remove the device;
• With the help of a candlestick, candles are broken. After that, all the landing wells are wiped with a rag; if there is a compressor, it is better to blow it with compressed air;
• Subsequently, one by one, new ignition sections are removed and installed. In this case, it is required to carefully insert them into the seat to avoid breaking the gap on the electrode. The tightening force of new elements should be in the range from 19 to 20 N * m;
• In the future, the dismantled units are installed in the reverse order, using new gaskets. In this case, the following efforts must be maintained when tightening the fastening bolts: the intake manifold - 27 N * m, the throttle unit - 10 N * m.

Throttle training

In theory, after replacing the spark plugs with one without disconnecting the power wires from the throttle assembly, there is no need to perform throttle training. But in practice, various options can be observed.

The following are the steps that need to be performed sequentially to teach remote sensing in various modes, while you need to have a stopwatch. You will first need to warm up the transmission, turn off all electrical devices, set the gearbox to the "P" position and check the battery charge level (at least 12.9 V).

Qashqai before upgrade from above, restyle 2010 from below

The sequence of actions when teaching DZ:

• After fulfilling the prerequisites, you must turn off the engine and wait ten seconds;
• The ignition is switched on, without starting and with the gas pedal released, for three seconds;
• After that, a full depression cycle is carried out, followed by releasing the gas pedal. Within five seconds, five repetitions are required;
• Subsequently, a seven-second pause is maintained, then the accelerator pedal is pressed all the way down and held. In this case, you need to wait for the CHECK ENGINE signal to light up, first it will start blinking;
• After setting the CHECK ENGINE signal, the gas pedal is held for three seconds and released;
• In the future, the power unit is launched. After twenty seconds, try to act on the accelerator pedal with a sharp set of revolutions. With proper throttle training, the idle speed should be kept between 700 and 750 per minute.

Replacing spark plugs for Nissan Qashqai 1.6 and 2.0 is a necessary manipulation to improve the engine. Thanks to the replacement, the motor will run more efficiently and longer.

In the most popular crossover in Europe and Russia, candles for a 1.6 liter engine should be replaced every 40,000 km, for a 2.0 liter power unit every 30-35,000 km and no later. Replacing spark plugs is not only necessary to increase engine performance and longevity, but also to understand engine problems. A frequent reason for replacement is both the loss of their quality by the candles at the end of the recommended service life, and as a result of engine malfunctions, in particular with oil, which almost completely fills the candles and prevents them from detonating.

The first bell that will tell you that you need to replace the spark plugs for the Nissan Qashqai 1.6 is insufficient engine thrust while driving, dull sounds in the engine and ignition problems. The engine with a volume of 1.6 liters with four in-line cylinders at 114 hp in power, which is basic for Kashkai, the main reason for replacement is time, since these motors are one of the best on the market in terms of tightness. Replacing the spark plugs in this engine can be done independently and without significant losses in time. The replacement will take only 1-1.5 hours.

The first thing you need to replace is the tools. So, to replace the spark plugs, you will need the following tools and components:

• New spark plugs;
• Wrench for candles 14 mm;
• Keys for 8 and 10 mm;
• Flat head screwdriver.

It is also worth buying a dynamic wrench for replacement, which will correctly distribute the efforts when tightening the candles. This key looks like this:

Before starting work, you should take a smartphone or camera to photograph the mechanisms at each stage of the work done. You will not remember everything completely and hopes for your memory is not worth it. If you can disassemble the upper part of the motor, then it will be a problem to assemble and, as evil, after such a collection, "extra parts" will appear. Armed with tools and a camera, we begin the process of replacing the spark plugs. The whole process takes 14 main points:

1. Having unscrewed all the bolts, the manifold and the damper should be raised, but it is worth remembering that the oil dipstick should be removed before understanding the damper. The probe looks like a thin stiff wire, you can see it in the photo above, it looks like a yellow ring from above. After lifting, the collector must be secured, preferably with wire.

Replacing spark plugs for Nissan Qashqai 2.0

Replacing spark plugs with Nissan Qashqai 2.0 almost completely repeats the replacement process on a less powerful 1.6 liter power unit. The thing is that the motors belong to the same series, which is typical for all representatives of this series - this is almost identical in structure. Both engines are naturally aspirated without an air blower, both are 4-cylinder and work with the same components. Therefore, if you need to replace the spark plugs with a 2.0 liter gasoline engine, see the instructions above.

Spark plug diagnostics

Spark plugs can tell the condition of the working units of the machine by the condition of their surface. The presence of soot, severe wear, or other deposits can indicate problems with the oil filter, fuel system, or cylinders. The main states of the spark plugs, the consequences of these conditions and recommendations on what to do are shown in the table:

Not the most difficult and time-consuming task is to replace the Nissan Qashqai candles. Knowing which elements are suitable for your car, you can significantly improve the quality of engine operation and increase the resource of the parts themselves. The ability to change them will save the budget, help out in the event of a consumable breakdown during a trip.

When to replace?

Replacing spark plugs for Nissan Qashqai is usually carried out when the car has traveled about 30 thousand km, it may be necessary to intervene earlier if the operating conditions were difficult and the elements were not installed the best. If you are not the first owner and buy a car, for example, 2012 or 2015, pay attention to the condition of consumables, the degree of their tightening.

It is better to replace candles immediately, even if they work properly. That way, you know when to change your Nissan Qashqai spark plugs next time, and the need won't catch you off guard.

Some manufacturers produce spare parts that can last 45 thousand km, but you still have to follow the timing. If the engine check lights up, start looking for the problem with checking the spark plugs, for this there is a special inexpensive device. In this case, it is not worth delaying the replacement, even if there are no visible engine malfunctions: repairs will be more expensive.

How is the installation going?

Replacing candles on a Nissan Qashqai 1.6 or 2.0 liter is carried out in the same way. The procedure requires some experience, since getting to the candle is not so easy.

It is advisable to purchase a torque wrench in advance. It will help to distribute efforts accordingly, facilitate installation. Get a candle wrench and long tweezers. Do-it-yourself replacement is necessary, observing the regulations. It is carried out on a cooled engine.

Replacement actions are performed in the following order: by opening the hood and finding the place where the candles are located, you still cannot get to them without doing some operations. First you need to disconnect the pipe located between the throttle valve and the filter element. It is necessary to remove the clamps and the hose of the ventilation system. After that, you can remove the vacuum hose, you need to do this carefully. Be careful not to damage the manifold. The cost of repairing it is quite high.

Remove the connector from the purge valve of the absorber, unscrew the brackets; the hose must be removed. You can see the bolt on the right - it also needs to be unscrewed. Remove 5 more manifold bolts. You can reach the spark plugs by lifting up the manifold and throttle.

Replacing the Nissan Qashqai spark plugs is accompanied by a very complex set of actions. In order not to forget the sequence, you can photograph the work done in stages. You can watch a detailed video to better consolidate the material. On Qashqai J11 2l or 1.6 everything happens the same. Clear the area around the consumables. Wipe it off, then start unscrewing.

It is very important that nothing gets into the intake holes.

It is advisable to cover the openings with a clean cloth before removing the ignition coils. After that, you can unscrew the old candles and install new ones. Good consumables suitable for mechanics - Denso FXЕ20HR11, you can install Bosch 0 242 135 524; do not save a few hundred rubles and buy cheap fakes. Their price is lower, but the service life is two or more times shorter, and the engine performance will significantly deteriorate. This will be confirmed by the one who installed such products on the Nissan Qashqai 2.0 or 1.6. Original products will last much longer and will not let you down at a crucial moment.

Today we will change the spark plugs on a Nissan Qashqai with a 2 liter engine.
The 2.0 liter 16-valve Nissan MR20DE engine has been produced since 2005 in Japan, at the company's largest engine plant in Yokohama. In Russia, the unit is known for such popular models as X-Trail and Qashqai (2007-2014)

Note! Replacing candles on a Nissan Qashqai 1.6 or 2.0 liter is carried out in the same way. The procedure requires some experience, since getting to the candle is not so easy

Many parameters of gasoline engines depend on the correct operation of spark plugs. Serviceability monitoring and their timely replacement is a condition for the correct operation of the vehicle.

The reasons for their natural and premature wear

The spark plug works under extremely extreme conditions: high temperature in the working cylinder; aggressive environment in the form of a mixture of fuel, air and oil; high ignition pressure; high voltage and temperature of the electrical spark. The simultaneous action of these factors leads to an increase in the processes of their natural wear and tear. This process can be significantly accelerated in the following cases:

• Reduce compression
• Worn valve stem seals due to oil entering the working volume
• Incorrect setting of the ignition angle, leading to the formation of increased carbon deposits;
• Selection of candles inappropriate to the engine brand;
• Misfire in cylinders;
• Incorrect ratio of gasoline / air in case of faults in the flow meter, lambda probe, air leaks;
• Incorrect operation of injectors.

Qashqai spark plug replacement schedule:

As prescribed by the maintenance regulations, the replacement of the Nissan Qashqai spark plugs should be done after 30,000 km or after 24 months, whichever comes first.
Many people consider candles to be a consumable and change every TO.

The main sign of the need to replace the spark plugs is misfiring (tripping). This is not always associated with candle problems. In order to finally determine the need for their mandatory replacement, the easiest way is to install a knowingly serviceable candle instead of a problematic candle. The easiest way to identify a possibly faulty spark plug is with the engine running. To do this, it is necessary to sequentially disconnect the high-voltage wires (or the connector of the individual ignition coil) from each of them. A non-working cylinder will be the one, when disconnected from which the nature of the engine does not change.

• visual malfunction (contamination, carbon deposits in the gap area, change in the normally gray color of carbon deposits, its moistening, mechanical chips on the insulator);
• unstable engine speed;
• increased smoke of exhaust gases;
• engine detonation;
• message of the control lamp "CHECK ENGINE" or on-board computer.
• increased fuel consumption

You should not rely on memory and try to remember the original work front. As a rule, only large nodes are remembered. To protect yourself from unnecessary worries about the correctness of the newly assembled structure, use your phone and take a photo.

1.Open the hood, unscrew the engine cover, which is held by two bolts under the head by 10:

2. Now we need to remove the intake manifold, unscrew 5 bolts of its fastening to the head.

The manifold holds 7 bolts! We unscrew the first 5 in front of the engine.

Another 1 bolt is located at the manifold on the left

3. To get to the 7th bolt it is necessary to unscrew the throttle valve! To do this, remove the connector from the absorber purge valve.

4. Take out the dipstick, loosen the clamps on the air duct. We remove it.

5. We take out the connector from the throttle valve: it is held by 4 bolts along the perimeter of the valve. We have two hoses for the throttle, we remove the clamps from them and plug them with bolts so that the antifreeze does not run away. Bolts 10 are ideal for these purposes. After removing the throttle valve, I recommend cleaning it at the same time; this can be done with a carburetor cleaner. Disconnect all hoses and remove the intake manifold.

Attention: do not allow dust and dirt to enter the intake windows, it is imperative to remove it and close the windows so that nothing spills into them during operation.

6. Remove the ignition coils by simply pressing on their clips. We unscrew the mounting bolts, head 10.

7. If possible, blow out the candle wells with compressed air so that debris does not get into the engine when unscrewing the candles (you can change one candle at a time so as not to shake debris into the candle wells). Spark plug 14 or a similar magnetic head (it is better to use a special spark plug wrench for Nissan Qashqai). We unscrew the candles.

Tighten the candles very carefully, otherwise if you overtighten, you can get to replace the internal combustion engine. The design of these heads is such that a coolant jacket passes around all the spark plug threads ... and thin-walled metal in these places ... It is worth overtightening and a crack forms along the plug thread.

Original candles, their article number 22401-CK81B according to NGK PLZKAR6A-11.
After installing the candles by hand and making sure that they are level, tighten them with a 22-24Nm or 2.3-2.5 kg / m torque wrench. Gently lower and tighten the spark plug coils first, then the connectors on them

Hello! From this article you will learn how the replacement of spark plugs Nissan Qashqai 2.0 l. All work was carried out on a 2008 Nissan Qashqai with a 2.0 liter engine and 141 hp. The check point is a variator. To begin with, it should be said that this procedure is not the easiest, but if you have basic knowledge and free time, then everything can be done independently. Usually, Nissan Qashqai owners go to the service, where they change the candles. This is the simplest solution to the problem. But if you are not used to overpaying for someone else's work, then you are welcome to us. We will tell and show everything clearly. And you just have to follow our instructions to complete all the actions on your car. So let's go.

As prescribed by the maintenance regulations, the replacement of the Nissan Qashqai spark plugs should be done after 30,000 km or after 24 months, whichever comes first.

What will it take to replace the spark plugs on the Nissan Qashqai?

1. Free time. All work takes about half an hour of free time.

2. Basic set of tools.

3. Straight arms.

4. New spark plugs. If you do not know what kind of candles you need, then you can turn to the help of the Internet or to sellers in a spare parts store. We took DENSO Iridium Tough spark plugs labeled VFXEH20. These are iridium-platinum candles that cost a lot of money. On 10/25/16 the price for one candle was about 1000 rubles. Since candles in Qashqai are not quite easy to change, it is better to immediately buy high-quality candles so that they will not be "touched" for the next couple of years. However, if you are not ready to spend money, you can always find cheaper analogs, of which there are now a great many in any online stores:

Work progress on replacing spark plugs Nissan Qashqai

1.Use the 10 "head to unscrew the engine trim and set it aside.

8. Now you need to unscrew the spark plug itself. To do this, use a special spark plug wrench for 14 ". Unscrew the old spark plug and screw a new one in its place. We perform a similar procedure on the remaining three spark plugs.

9. Putting everything together in reverse order. If the intake manifold gasket has become rigid, then along the way you can replace it in order to eliminate air leaks during engine operation.

That's all! At this, the replacement of the Nissan Qashqai 2.0 spark plugs can be considered complete. In addition, we recommend watching a video in which everything is clearly shown.
