Spark plugs Nissan Qashqai: description, characteristics, replacement. Replacing spark plugs Nissan Qashqai How to replace spark plugs with Qashqai

Nissan Qashqai has been produced since 2006 to the present day. In the domestic market, the car is presented with 1.6 (HR16DE) and 2.0 liter (MR20DE) gasoline engines, as well as one modification with a 1.5 liter diesel engine.

Spark plugs for Nissan Qashqai 1.6 and 2.0

From the factory, the car is equipped with original spark plugs under the article 22401CK81B. Sold original spark plugs in original Nissan packaging. The manufacturer of the part is NGK. Price - 580 rubles. Direct analogue of a branded part from the manufacturer - PLZKAR6A-11(she is NGK 5118). Price - 380 rubles. In fact, it's the same piece. Spark plugs for Qashqai do not differ in any way depending on the engine size. There is also no division depending on the generations of the car. Spark plugs Nissan Qashqai J10 (first generation) and J11 (second generation) have the same serial number.

Characteristics of spark plugs Nissan Qashqai 1.6 and 2.0

As the experience of many Qashqai owners shows, spark plugs in the original packaging 22401CK81B there are often fakes. The main sign by which you can distinguish the original is that there should be candles in the branded box. PLZKAR6A-11 (NGK 5118). Also, a real original candle has even electrodes, a gap of 1.1 mm, a platinum patch soldered on the side electrode, just opposite the main electrode. The sealing ring is not removed (on fakes, most often it dangles). Experts recommend buying original spark plugs for Nissan Qashqai directly from the manufacturer - NGK 5118. In original Nissan packaging, fakes are much more common.

Also for Qashqai there are original iridium candles under the number 22401JD01B. Price - 830 rubles. They are not installed from the factory, but are recommended by the manufacturer as an original spare part. The manufacturer of this part is Denso. She, like NGK, is the official supplier of Nissan parts. Direct analogue of the original Nissan spark plug 22401JD01B manufacturer Denso - FXE20HR11. Price - 840 rubles. The electrode material is iridium. As in the first case, these spark plugs are also very often counterfeited. The signs by which you can distinguish a fake are the same as those of the first factory spark plug. In a box with a number 22401JD01B always have a Denso spark plug FXE20HR11. In all other cases, it is a fake.

According to the manufacturers of the spark plug with an iridium electrode, its service life is longer, and the performance is much higher. In practice, drivers did not notice any significant differences between spark plugs with a platinum and iridium electrode.

Analogues of original spark plugs Nissan Qashqai

When on Qashqai, you should also pay attention to the most popular analogues, which are not inferior in quality to the original, but at a slightly lower price:

0242135524 . Producer - BOSCH. Price - 420 rubles. This candle model has a proprietary Double platinum technology, in which platinum is also soldered into the side electrode. This improves the quality of ignition. The item has positive feedback from buyers. Electrode material - platinum;

Z325. Producer: Beru. Price - 350 rubles. The electrode material is platinum. quality analogue. The overwhelming majority of reviews about this model are positive;

OE207. Producer - CHAMPION. Price - 430 rubles. Also a high-quality analogue from an American manufacturer. According to customer reviews, the quality of this candle model is not worse than the original.

Also on the forums you can often find a recommendation to put Denso Iridium Tough candles VFXEH20. Price - 850 rubles. They combine two technologies - Iridium and Platinum. Which can provide a long period of operation up to 100,000 km. Also, these candles are special in that they have a reduced electrode gap of up to 0.4 mm, which increases the efficiency of the engine and leads to a decrease in fuel consumption.

When they change

It is recommended to change spark plugs every 30 thousand kilometers, or 2 years of operation. Every 15,000 km it is recommended to check them. As the experience of Qashqai car owners shows, original spark plugs with a platinum electrode can work out up to 60,000 km. Signs of the need to replace candles are standard - not smooth engine operation, increased fuel consumption, loss of dynamism.

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 with 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 depend on the correct operation of spark plugs. gasoline engines. Serviceability control and their timely replacement is a condition correct operation vehicle.

Causes of their natural and premature wear

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

• Compression reduction
• wear and tear valve stem seals due to oil ingress into the working volume
• Incorrect installation of the ignition angle, leading to the formation of increased soot;
• Selection of candles that do not correspond to the brand of the engine;
• Misfires in cylinders;
• Incorrect gasoline / air ratio in case of malfunctions of the flow meter, lambda probe, air leakage;
• Incorrect operation of injectors.

Qashqai spark plug replacement schedule:

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

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

• visual malfunction (contamination, soot in the gap area, change in the normally gray color of soot, its moistening, mechanical chips on the insulator);
• unstable engine speed;
• increased opacity 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 front of the work. 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 on by two 10 head bolts:

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

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

1 more bolt is at the manifold on the left

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

4. We take out the probe, loosen the clamps on the duct pipe. We take it off.

5. We take out the connector from the throttle: it is held by 4 bolts around the perimeter of the damper. We have two hoses going to the throttle, Remove the clamps from them and plug them with bolts so that the antifreeze does not run away. Bolts of 10 are ideal for these purposes. After removing the throttle, 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 inlet windows, it is necessary to remove it and close the windows so that nothing falls into them during work.

6. Remove the ignition coils by simply pressing their latches. We unscrew the mounting bolts, with a head of 10.

7. If possible, blow out the candle wells with compressed air so that when the candles are unscrewed, debris does not get into the engine (you can change one candle at a time so as not to shake debris into the candle wells). candle key 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 candle threads ... and thin-walled metal in these places ... It is worth pulling and a crack forms along the candle thread.

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

Spark plugs (SZ) play one of the main roles in the ignition system. Their failure can cause malfunctions in the entire operation of the internal combustion engine. The article is devoted to SZ for Nissan cars: when a replacement is needed, which candles to put in, how to replace Nissan Qashqai candles with your own hands.

In what cases is it necessary to replace spark plugs?

SZ serve to form a spark that ignites the combustible mixture.

The smooth operation of the engine depends on the quality of sparking. If at least one of the 4 fails, then further operation of the motor will be impossible.

SZ have their own resource. According to the regulations on Nissan cars, they are changed after 30 thousand kilometers. Although SZ must withstand significant thermal and mechanical loads, they are subject to wear and tear and can fail at the most inopportune moment. To prevent an unpleasant surprise on the road, a visual inspection of the SZ should be done at each inspection.

What kind of candles to put?

To avoid problems, it is better to purchase originals for replacement. For Nissan Qashqai, such SZs as NGK Plzkar6a with an iridium tip are suitable. The average service life of the SZ is different and largely depends on the material of the electrodes.

Chrome-nickel alloy has high thermal conductivity and high corrosion resistance. Silver has the best thermal conductivity. The advantage of platinum electrodes is high resistance to corrosion and resistance to burning (the author of the video is VybratAuto - Automotive information site).

Replacing SZ with Nissan is a laborious process, so it’s better to buy high-quality products right away. True, they are expensive. If you want to save money, you can find cheap analogues, of which a large number are offered on the Internet. But such savings can result in frequent replacement of candles.

DIY replacement instructions

The procedure for replacing the SZ with a Nissan Qashqai, Nissan Note and Nissan Juke is similar, especially in that it is not easy to get to the SZ. Although this process is laborious, it is quite doable even for a novice motorist.

Tools and materials

For work, you need to prepare the necessary tools and materials:

• a set of keys and screwdrivers;
• special candle key;
• torque wrench;
• new set of SZ;
• clean rags.

If necessary, it is worth changing the gasket of the throttle assembly and intake manifold.

The process of dismantling and replacing SZ

If the car is after a trip, then you need to wait until it cools down. Work is carried out on a cold engine.

Replacing candles Nissan Qashqai consists of a sequence of steps:

1. First, the decorative protective cover is removed from the engine. Under it is the collector of interest to us.
2. There is a pipe between the throttle valve and the filter. To remove it, you need to unscrew the two fasteners and loosen the clamps. Before removing the branch pipe, it is necessary to disconnect the ventilation system hose from the cylinder head.
3. With careful movements, so as not to damage the plastic manifold, you need to disconnect the vacuum hose.
4. The next step is to remove the manifold. To do this, unscrew 7 bolts. 5 of them are on top, 6th on the left. To get to the 7th, you need to remove the connector from the absorber purge valve and dismantle the throttle by unscrewing 4 bolts around its perimeter.
5. After pulling out the dipstick so that it does not interfere, you can raise the manifold. It is not necessary to remove it completely, you can simply tie it up with a rope or wire.
6. Now SZ is available. Before replacing them, everything should be thoroughly cleaned of dirt and oil, while not dropping anything in the cylinder head.
7. For safety, you can cover the cylinder head exhaust holes so that nothing falls there.
8. Now we change the SZ one at a time. First, the connector is disconnected from the ignition coil. Then the coil itself is removed.
9. Under the coil is an NW, which is unscrewed using a special candle key for Nissan.
10. Then we fix a new candle in the candle key and screw it in manually. Having screwed it up to the stop, you should take a torque wrench and tighten it with a torque of no more than 18-19 Nm. If overtightened, spark plug threads may crack and become unusable.
11. Similar actions are performed for all 4 SZ.
12. After replacing all the SZ, the assembly is performed in the reverse order.

After complete assembly, you need to start the engine and check its operation with the changed candles.

Today we received a car Nissan Qashqai (Nissan Qashqai) with a 2-liter engine, manufactured in 2012, on which it is necessary to replace the spark plugs. We will show you detailed photo and video instructions on how to do it yourself.

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

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

We take out the probe, loosen the clamps on the duct pipe. Let's take it off:

We pull out the connector from the throttle valve. We have two hoses going to the throttle, remove the clamps from them and plug them with bolts so that the antifreeze does not run away. Bolts of 10 are ideal for these purposes. After removing throttle I recommend cleaning it at the same time, this can be done with the help of a carburetor cleaner. Disconnect all hoses and remove the intake manifold.

In our case, dust from above got into the inlet windows, it is necessary to remove it and close the windows so that nothing falls into them during work.

We remove the ignition coils by simply pressing on their latches. We unscrew the mounting bolts, with a head of 10:

If possible, we blow out the candle wells with compressed air so that when unscrewing the candles, debris does not get into the engine. We unscrew the candles with a candle key for 14 or a similar magnetic head:

We will put original candles, their article is 22401-CK81B according to NGK PLZKAR6A-11. I recommend tightening new candles with a torque wrench, according to technical regulations manufacturer, it is necessary to tighten them with a force of 22 to 25 Hm. We assemble in the reverse order.

Replacing spark plugs with Nissan Qashqai 1.6 and 2.0 is a necessary manipulation to improve the engine. Thanks to the replacement, the motor will work 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 the performance and durability of the motor, but also to understand the problems with the engine. A frequent reason for replacement is both the loss of their quality by 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 detonation.

The first bell that tells you that you need to replace the spark plugs with a Nissan Qashqai 1.6 is insufficient engine traction when driving, dull sounds in the engine and problems with ignition. In a 1.6-liter engine with four in-line cylinders at 114 hp. in power, which is the base for the Qashqai, the main reason for the replacement is time, as these motors are among the best on the market in terms of tightness. The replacement of spark plugs in this motor can be done independently and without significant loss of time. Replacement will take only 1-1.5 hours.

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

• New spark plugs;
• Key for candles 14 mm;
• Keys for 8 and 10 mm;
• Screwdriver with a flat head.

It is also worth buying a dynamic key to replace it, which will correctly distribute the forces 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 relying on 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, unfortunately, after such a collection, “extra parts” will appear. Armed with tools and a camera, we begin the process of replacing spark plugs. The whole process takes 14 main points:

1. Having unscrewed all the bolts, you should raise the manifold and damper, but it is worth remembering that you should remove the oil dipstick before understanding the damper. The probe looks like a thin rigid 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 a Nissan Qashqai 2.0 almost completely repeats the process of replacing 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 atmospheric without an air blower, both 4-cylinder, work with the same components. Therefore, if you need to replace the spark plugs with a 2.0 liter gasoline engine, you should look at the instructions above.

Spark Plug Diagnostics

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