Nissan Teana replacing spark plugs. Replacing Nissan spark plugs. How many spark plugs for Nissan Teana

Spark plugs are one of the most important elements any motor unit of the car. The designated car parts are involved in the procedure for igniting the combustible mixture. The presented candle is a fairly durable part of the vehicle. However, it operates under high loads, as a result of which it is subject to wear. In addition to natural wear and tear, the above-mentioned element of the machine is also affected by low quality fuel. Based on the information indicated, we conclude that the spark plugs need to be periodically replaced with new ones.

How do spark plugs work?

As mentioned earlier, spark plugs are special devices that ignite combustible fuel in the engine cylinder.

The process of functioning of one cylinder can be divided into four points:

• To begin with, the engine cylinder of a Nissan Teana j32 is filled with a flammable substance;
• Afterwards, the fuel mixture is compressed by the piston, as well as ignited by the spark plug;
• Next comes the procedure for expanding the volume of the cylinder. The indicated process is carried out due to the movement of the machine piston in the opposite direction. When a fire occurs, the pressure increases significantly, resulting in the reverse movement of the car piston and, due to this force, the vehicle can drive;
• Afterwards the combustion products are pushed out through exhaust pipe car brand Nissan Teana J32.

The operation procedure of the motor unit is circular, in the engine of any vehicle, in this case the Nissan Teana j32, is far from one cylinder, and the number of spark plugs is always equivalent to the number of cylinders. As a result of this, the car owner may experience certain problems with the car's engine. This is due to the fact that if a car enthusiast who owns a Nissan Teana J32 car breaks a spark plug in one cylinder, or a breakdown occurs to him, then he cannot distinguish the presented nuances. If there are any problems with the vehicle’s engine, then most car enthusiasts first purchase new spark plugs and replace them, partly this is the right move. This is explained by the fact that repairing a motor unit, and even disassembling it, costs much more than replacing old spark plugs with new ones.

Deviations from the optimal combustion procedure

Deviations in the functioning of spark plugs from the optimal combustion procedure vary. If the designated part of the Nissan Teana J32 is faulty, then ignition may be missed, as a result of which one cylinder chamber stops working. Glow ignition is one of the most common deviations of the designated car part. It is accompanied by a late or early release of a spark, which leads to the fact that the engine unit of a Nissan Teana j32 vehicle will not function at full speed. full power. Another common deviation is detonation. It forms in the cylinder, in the place farthest from the spark plug and occurs due to strong compression of the combustible mixture.

The process of replacing spark plugs

It is recommended to replace and maintain elements and parts of the ignition system that are in direct contact with the engine unit housing when the engine is cool. Any car enthusiast can replace spark plugs - this is a simple procedure that does not require significant skills and knowledge. To carry it out, the owner of a Nissan Teana j32 will need to prepare certain tools.

What do you need to have with you?

• Collar (1/2);
• Long head 14 (1/2);
• Extension 25 mm (1/2);
• Socket wrench 10;
• Tubular wrench 10;
• Slotted and Phillips screwdriver;
• Pliers;
• Carburetor cleaner;
• Hexagons;
• Work gloves;
• Waste fabric;
• Six new spark plugs - Nissan, number 22402JD01B.

After the above tools have been prepared, the car owner can begin replacing the spark plugs on the Nissan Teana 2.5 v6.

Replacement procedure:

• First you need to open the hood of the vehicle and remove the decorative plastic from the engine unit;

• When performing the above action, access to the first three spark plugs will open. They can be replaced at this stage;

• To do this, you need to press the latch and pull out the contact chip from the ignition coil. Using a 10mm wrench, unscrew the fixing bolts. After this, the owner of a Nissan Teana j32 car can pull the coil up, thereby pulling it out;
• Next, you need to unscrew the first spark plug that is unusable with a spark plug wrench;

• Afterwards the new part is installed in place. It is tightened with a force of 17 Nm. Do not tighten it any further, as this can damage the threads of the spark plug well and the threads of the spark plug itself. This can lead to costly repairs;
• Afterwards, the coil needs to be installed in place, tighten the bolt and insert the contact chip;
• The above process should be done for the remaining two spark plugs;
• The further procedure is more complicated. The remaining three spark plugs are located under the intake manifold, which must be removed. The indicated process should be carried out sequentially;
• Frame air filter dismantled together with the corrugated pipe that goes to the filter;
• Afterwards you need to remove throttle valve. It is secured with four hex bolts. You should check about the rubber hose. It must be disconnected from the throttle valve;

• Next, unscrew the three screws from the manifold holding the metal tube;
• At this stage, it is necessary to remove two crankcase ventilation hoses;
• Then the five screws securing the intake manifold are unscrewed;
• The photo above shows the order of tightening the intake manifold bolts;
• Next, remove the intake manifold;
• At this stage, the car owner has access to three remaining spark plugs;
• Their replacement is carried out in the same way as the first three. When performing the presented process, it is recommended to cover the openings of the inlet ports of the cylinder head (cylinder head) with an unnecessary rag. This is done in order to avoid dirt getting into them;
• Along the way, the car enthusiast can thoroughly wash the throttle valve and intake manifold. They are washed with carburetor cleaner;
• After all the spark plugs have been replaced, you need to reassemble everything in the reverse order.

Frequency of replacing spark plugs on Nissan Teana j32

In order for the engine of a Nissan Teana j32 to function stably and without failure, its owner needs to monitor it. According to the regulations, when passing the planned maintenance The vehicle must be replaced with new spark plugs. The frequency of carrying out the indicated procedure is established by the manufacturer of the car, in this case the Nissan Teana J32. However, if the engine unit is in good working order, there are no deviations in the ignition system, and also provided that the owner of the vehicle uses only a high-quality fuel mixture, the period of optimal functioning of the spark plugs is thirty thousand kilometers. The period may be extended if the car owner uses platinum or iridium spark plugs.

Possible breakdowns and their causes

Due to the fact that with increased work of the cylinder, the temperature in its chamber increases sharply, the spark plug may be partially damaged and a lead coating will form on it. The temperature in the designated part is greatly influenced by the fuel mixture used by the car enthusiast in the Nissan Teana J32. This happens due to the glow of the spark plug. The problem may be in the piston, exhaust valve, piston rings, as a result, the insulator of the designated part may melt.

Adverse consequences of not replacing spark plugs on time:

• The service life of the catalyst is reduced. If the combustible mixture in the car’s cylinders is insufficiently ignited, the remaining unburned fuel enters the catalyst. After the combustible mixture enters the catalyst, it burns out, as a result of which the layer on the honeycomb of the designated part also burns out. In addition, the lambda probe may also be damaged;
• The ignition coils fail. As a result of an increase in the breakdown voltage, the distance between the electrodes of the spark plug increases - as a result, a breakdown of the insulation of the coil layers occurs and it ceases to function;
• The operating period of the motor unit is reduced. The entry of a combustible mixture into a cylinder that is faulty leads to fuel entering the engine crankcase. In addition, the cylinder wears out and the oil life decreases.

If a car enthusiast uses a Nissan Teana j32 with faulty spark plugs, then explosive pops may form inside the combustion chamber. As a result, the car owner will have to change piston group, crankshaft and connecting rod.

Hi all! From this article you will learn how to replace Nissan Teana spark plugs. In fact, the procedure is not complicated, but it requires time and a little technical skill. However, if you use our instructions, you can actually do everything without going to a car service center. This means that you can save on work and direct your money in a different direction. And if you don’t know, then look at our material on the website. So, let's go.

Frequency of replacing spark plugs on Nissan Teana

How many spark plugs are there for a Nissan Teana?

There are two types of engines installed on the Nissan Teana - a V6 and a regular in-line four. It is logical that the V6 has 6 spark plugs, and the “four” has 4 spark plugs. We have at our disposal Nissan Teana in a J32 body with a V6 VQ25DE engine. The spark plugs for our car are marked Denso FXE20HR11. These are platinum candles that cost about 900 rubles. per piece. Yes, the set costs about 5,400 rubles. It’s expensive, but it’s better to overpay than to buy something cheaper but of lower quality. Here are some analogues:

Here are less expensive analogues:

Work progress on replacing spark plugs Nissan Teana J32

Please note that replacing Nissan Teana spark plugs should be done on a cooled engine.

1. Open the hood and remove the decorative plastic from the engine. Here's what we see:

2. Access to the first three spark plugs is open. You can replace them immediately.

3. Press the latch and pull out the contact chip from the ignition coil. We unscrew the fixing bolts with a 10" wrench. Now you can pull the coil up and pull it out.

4. Take spark plug wrench and unscrew the first spark plug. We take a new candle and wrap it in place. Tighten with a force of 17 Nm. Do not over-tighten, as this may damage both the spark plug threads and the spark plug well threads. And this will result in expensive repairs.

We put the coil in place, tighten it with the bolt and insert the contact chip.

5. We perform this procedure for the remaining two spark plugs.

6. Now comes the hard part. The remaining three spark plugs are located under the intake manifold, which will have to be removed. This is done sequentially.

7. Dismantle the air filter housing along with the corrugated pipe going to the filter.

8. Remove the throttle valve. It is held on by 4 hex bolts. Don't forget to disconnect the rubber hose from the throttle body.

10. Remove two crankcase ventilation hoses, as shown in the photo below:

(The photo above shows the tightening order of the intake manifold bolts.)

And remove the intake manifold.

Now we have access to the remaining three spark plugs.

Their replacement is carried out in the same way as the first three pieces. During replacement, it is advisable to cover the openings of the cylinder head inlet channels with a napkin or rag to prevent dirt from getting there.

At the same time, you can wash the intake manifold with carburetor cleaner. You can also flush the throttle valve.

12. After replacing the spark plugs, everything is assembled in the reverse order.

That's all! At this point, the replacement of Nissan Teana spark plugs can be considered complete. Thank you for your attention. We also recommend that you read the articles

Launch gasoline engine is not possible if there is no spark in the combustion chamber of the cylinder. To ensure normal operation power unit, the spark plugs must function smoothly. Therefore, it is very important to carry out routine inspection and replacement of spark plugs in Nissan cars. All the details are in this article.

Spark plug: what role it plays, what it consists of

The role of the “igniter” in the car’s ignition system is performed by the spark plug, which produces a spark. The device allows you to convert a flammable mixture - an emulsion containing particles of gasoline and air - into thermal energy. Thanks to the latter, the movement of the engine pistons occurs.

Spark plug used in modern cars, consists of:

• housings,
• insulator,
• central electrode,
• side electrode.

Inside the central electrode is a copper core. It can also be used in the side electrode, which promotes improved heat dissipation. Similar solutions are offered by companies that produce expensive candles. Also, some manufacturers coat the central and (or) side electrodes with platinum, thereby protecting the spark plug elements from rapid destruction.

The average service life of a spark plug is 30 thousand kilometers. When choosing spark plugs, you must follow the instructions for the car. The Nissan car manufacturer recommends replacing spark plugs after 15-60 thousand kilometers, depending on the car model and engine. We, in turn, recommend Russian motorists change spark plugs every 15 thousand kilometers, this is not always due to quality fuel which has a detrimental effect.

Replacing spark plugs in Nissan cars

To replace spark plugs, you will need a standard set of car keys. For example this:

Let's take a car as an example. Nissan Qashqai. To replace spark plugs on this model you must:

1. Remove the engine protective cover.
2. Unscrew the air duct on the throttle valve.
3. Unscrew the throttle valve, which is attached to two bolts.
4. Remove the intake manifold. To do this, you need to unscrew the lower and upper bolts (for example, on the Qashqai model there are seven of them: five at the bottom and two at the top).
5. Remove the ignition coil, which is secured by several bolts.
6. Unscrew the spark plugs using the ignition coil (there is a special hole in its lower part).
7. Insert each spark plug (new) into its seat.
8. Fix the candles.
9. Secure the ignition coil.
10. Install and secure the intake manifold.
11. Attach the throttle valve.
12. Connect the air duct.
13. Install the protective cover.

By time the procedure takes about 60 minutes (+ registration and about 5-10 minutes)

Total cost of work: 1200 rubles for replacement + cost of original spark plugs from 450 rubles. (In this case, the client purchased the candles himself)

Attention: All prices indicated are current at the time of work.

Photo report on replacing spark plugs on a 2006 Nissan Teana.

1. We accept the car for work. We create an order. Technological washing was not carried out at the client's request.

2. Unscrew the engine boot.

3. Remove the manifold to get to the spark plugs.

4. So, we got to the ignition coils. We begin to remove them (first the coils are unscrewed, then they are pulled straight up).

To unscrew old candles, we use a candle wrench (candlestick) - a device that allows you to carry out the procedure more quickly and efficiently. The spark plugs are unscrewed counterclockwise.

5. Replace old spark plugs with new original ones Nissan spark plugs. New spark plugs must be screwed in with a force of approximately 30-35 Nm. Do not over-tighten (the thread may become damaged) or under-tighten (the spark plug may fly out).

The spark plug wells must be covered with a cloth, which helps prevent foreign objects from getting into the engine cylinder (in this case, you will have to disassemble the engine).

6. After replacing all the spark plugs (2 rows of 3 each), install the manifold back.
