How to remove and clean the injectors on a VAZ 2109 (injector)?

Injectors - what are they?

Let's figure out what injectors are and what they are needed for. Injectors are an electromagnetic mechanism designed to spray fuel into the cylinder. Their number depends on the number of cylinders in the car. The VAZ car has 4 cylinders, therefore there are also 4 injectors.

A serviceable and clean injector sprays fuel evenly without any delays or jerks.

A clogged injector may not spray fuel at all or, on the contrary, pour it in drops. As a result, the engine cannot operate normally and correctly.

Fuel injection system for VAZ 2108, 2109, 21099 cars

Installing an injector in a VAZ 21099 car

Reliable operation of the fuel system of the VAZ 21099 depends on the injector. Its clogging can lead to large excess fuel consumption, unstable idling and a decrease in engine power, and the car jerking during acceleration. Many gas stations sell low quality fuel that contains dirt, benzene, water, sulfur and olefin. This leads to the accumulation of tarry deposits in the fuel system, rail, and on the surfaces of the injector. This article discusses how to flush the injector on a VAZ 21099 car yourself.

Symptoms of clogged injectors

Loss of dynamics is one of the main signs of clogged injectors. If they are contaminated, the car simply will not accelerate properly.

• Unstable idling, the engine at idle will operate unstably and intermittently.

• Starting difficulties can occur when there is contamination or when the injectors stop holding pressure. Fuel begins to drip into the cylinder, which can cause popping sounds in the exhaust pipe.

• Ringing fingers are inevitable when the spray nozzle is clogged; this is due to the fact that the fuel entering the cylinder is mixed with air and the concentration of fuel in this mixture is quite small, so the engine experiences detonation.

Driving with dirty injectors will not provide any driving pleasure. And driving with such a problem is highly not recommended.

How to check for faults

The car owner can independently check the performance of the injectors on his car. The procedure is quite simple and does not require special training or expensive equipment. In garage conditions, diagnostics can be performed with a set of open-end wrenches, screwdrivers and a tester with a resistance measurement mode.

Reasons indicating problems

Diagnostics must be performed not after any period of operation or mileage has expired, but in the presence of external manifestations of injector failures. In cases where other vehicle systems are operating normally, the following indicators indicate problems with the injection solenoid valves:

• at idle there is instability in engine speed;
• starting the engine is difficult - the engine may stall;
• when overclocking it is impossible to achieve the same dynamics;
• The amount of fuel consumed has noticeably increased.

1. Open the hood.
2. Unclip the plastic clips that secure the valve's power cable. Remove the connector.
3. Switch the tester to resistance measurement mode and take measurements of the windings of each of the injectors in turn. That is, you need to apply one contact of the tester to each of the five terminals, and the second one to the fifth wire for power.
4. Optimal resistance values ​​in all cases should be in the range of 11–15 ohms. If at least one pin shows deviations, it will be necessary to change the nozzle.

When to clean injectors

Cleaning of injectors on Lada cars is carried out according to the condition of the car. If there are no problems with your car, then there is no need to clean them. Also, to find out for sure whether the injectors need to be cleaned, you first need to diagnose the fuel system. You can learn more about how to diagnose the fuel system in our article.

The manufacturer recommends cleaning the injectors every 50,000 km. Since the fuel at our gas stations leaves much to be desired, just before this mileage they begin to become clogged and flushing them will be useful. You can wash it at a service station, or you can do it yourself. Next, we will look in detail at how to wash the injectors on a VAZ car at home.

Repair of VAZ 21099 injector

In most cases, you can get by by simply cleaning the injector. This procedure can be done at every car service center. To prevent serious damage, have your car diagnosed in a timely manner. You can do the cleaning yourself using chemicals, but it will not be complete. If you decide to clean the injector yourself, you need to buy a repair kit for rubber O-rings for injectors and injector cleaning fluid.

Before performing this procedure, you need to remove the terminals on the battery and disconnect all power supply connectors near the injector. Then we proceed to remove the manifold, carefully unscrew and disconnect the pipes from it. After this, we release the pressure in the fuel rail of the injector by pressing the nipple on the left side of the rail.

Next, carefully move the sealing clamps from the injectors and, by swaying in different directions, remove our injector. It is not difficult to see whether the injectors are dirty. After disconnecting each nozzle, place them in a jar with a pre-prepared chemical mixture for 30–40 minutes. Once you have completed this procedure, we proceed to reassemble our fuel system in reverse order. Be sure to remember to change the o-rings on the injectors that come in the repair kit.

Methods for cleaning injectors

Injector flushing additives

There are a huge number of different additives for flushing the injector. Such additives are poured into the car tank and mixed with fuel. The mixture of fuel and additives enters the main elements of the fuel system and flushes them, including the injectors. But, as a rule, such washings do not bring much results, since all the dirt that was washed away to the injectors gets and settles on them, which can only aggravate the situation. Using this method is not recommended.

How to clean injectors yourself

Method 1: fuel additive

The simplest and relatively gentle cleaning method is using special additives. More suitable for preventing the formation of deposits inside all elements of the fuel system - from the gas tank to the injectors.

The disadvantage of such additives is that on cars with high mileage they lift all the dirt from the gas tank and pipelines. As a result, the filters and the injectors themselves become clogged, which leads to even more disastrous consequences.

You will need

• Fuel additive-injector cleaner.

How to do

1. Pour the product into the tank immediately before refueling according to the proportions in the attached instructions.
2. Operate the vehicle as normal.
3. For the best cleaning effect, it is advisable not to stand in city traffic jams, but to drive along the highway.

Method 2: flushing the injectors on the engine

This cleaning method is more difficult, but also more effective. It not only cleans the injectors, but also additionally decarbonizes the piston rings and also increases compression. Flushing is carried out with the engine running, which runs on detergent instead of gasoline.

The main disadvantage is that the quality of washing cannot be controlled. Other disadvantages include the entry of aggressive substances into the exhaust tract and potential damage to the catalyst. After using some products, spark plugs may need to be replaced.

You will need

• Injector cleaner;
• fuel filter;
• two-liter plastic bottle;
• wire;
• 1 m of fuel hose with a diameter of 10–12 mm;
• 3 clamps with a diameter of 9–14 mm;
• 2 nipples from a tubeless tire;
• bolt M12;
• screwdriver or drill;
• drill with a diameter of 12½ mm;
• tire compressor;
• spark plugs (if their replacement is recommended in the flushing instructions).

How to do

1. Drill one hole each in the cap and bottom of the bottle. Install the nipple with the valve turned out into the cover. The nipple will supply liquid to the ramp.
2. Insert the second nipple assembly into the hole in the bottom. You will need it to pump in air later to create pressure.
3. Place one end of the hose onto the nipple in the cover, and install the other on the fuel filter, according to the arrow on the body. Tighten the ends of the hose with clamps. Wrap the bottle with wire so you can hang it.
4. Warm up the engine to operating temperature and turn it off. Disable the fuel pump by removing the corresponding fuse.
5. Start the engine. Let it run to relieve pressure in the rail. Wait until the engine stops.
6. Disconnect the fuel supply hose from the line and connect it to the filter of an improvised flushing receiver. Pour the wash into the bottle, close the cap and hang it on the hood.
7. If the car has a return fuel line, plug it using a bolt of suitable diameter and clamp it with a clamp.
8. Use a compressor to pump air into the bottle until the pressure reaches 2–2½ bar.
9. Start the engine and let it idle for 15 minutes, maintaining the pressure in the bottle at the same level.
10. Turn off the engine and wait about 15 minutes for all deposits to soak off.
11. Start the engine again and use up any remaining flushing fluid while maintaining the RPM between 1,000 and 1,500.
12. Remove the bottle, the return plug and connect everything as normal. Don't forget the fuse.
13. If the flush is aggressive and affects the spark plugs, replace them.

Method 3: washing and removing the injectors

The most difficult method, which involves removing the fuel rail and injectors. At the same time, it is the most effective and targeted - there is no harm to other elements of the system. For flushing, the operation of an injector is simulated, and a carburetor cleaner is used instead of gasoline.

The only disadvantages of this method are the difficulty of dismantling the ramp and injectors, as well as the need to replace microfilters and o-rings.

You will need

• Aerosol cleaner for carburetors;
• syringe 5 mm³;
• 9-volt Krona battery;
• 1–2 m of wires;
• doorbell button or other without fixation;
• 4 alligator clips;
• screw with a diameter of 4 mm;
• pliers;
• repair kit for injectors (only rubber rings and a filter are allowed).

When replacement is required

There are several signs that indicate you need to at least remove and check the condition of the fuel injectors. Next, a decision is made to clean or replace the elements.

Pay attention to the behavior of your car and specifically the engine. They will tell you if there is something wrong with the injectors. This may manifest itself as follows:

• The engine produces less power, the same acceleration efficiency is not felt;
• If the engine performs poorly or lacks power, fuel consumption still increases;
• Poor starting is not a rare sign of injector failure;
• If the engine does not hold idle speed well, the injectors may well be the cause;
• The amount of toxic components in exhaust gases increases;
• At idle the speed increases.

Cleaning injectors on VAZ 2108, VAZ 2109, VAZ 21099

Welcome! Do you want to learn how to clean fuel injectors on fuel-injected cars of the Samara family? If you are interested in this, then continue reading the article further, in it you will find instructions for properly cleaning the injectors.

Summary:

When should you clean your injectors? Each person cleans their injectors differently, because as a rule, there are no exact numbers that would indicate how often fuel injectors should be cleaned. But there are small signs by which you can determine that the injectors are not working correctly, the signs are as follows:

• Basically, if the injector is heavily contaminated, the car’s engine may become difficult to start.
• It may begin to exhibit unstable operation, this will be especially noticeable at idle.
• The engine may also stall at idle.
• And in some cases, its speed may increase while operating at the same idle speed.
• And finally, due to improper operation of the fuel injectors, when driving the car may experience jerks, various kinds of failures, and fuel consumption usually increases.

Removal and replacement

Now we’ll talk specifically about how to properly remove and replace old injectors that have lost their usefulness with new units.

First, a good video instruction, and below in the text, step by step, how to proceed.

The process of dismantling each of the 4 injectors is identical, so there will be no difference in the process.

Perhaps the most problematic step in replacing or cleaning injectors is dismantling the fuel rail. Therefore, we will separately tell you how this knot is removed.

The fuel rail is the bar on which the injectors are installed. It is secured with a pair of bolts on the intake manifold. To the left of the ramp there is a fuel pressure control fitting. To remove it you need:

• Disconnect the negative terminal from the battery. Nobody needs short circuits;
• Relieve pressure in the fuel line;
• Remove the air filter and disconnect the intake pipe hose, then remove the vacuum hose of the pressure regulator;
• Disconnect the power supply wire from the idle speed sensor. To do this, simply press out the pad retainer, made of plastic;
• Disconnect the block with the wires coming from the injectors;
• Disconnect the drain and supply hoses from the fuel pipes;
• Unscrew the pair of mounting bolts that secure the fuel rail to the intake pipe;
• The fuel pipes are held in place by a special holder, which requires unscrewing one mounting screw to remove;
• Remove the fuel rail by sliding it along the axis of the fuel nozzles. This way they will come out of their seat on the intake pipe;
• Assembly is performed in reverse order.

Please note that under the fuel rail mounting bolts there are washers that must be returned to their place during reassembly or replaced with similar new ones.

If you need to add a video on removing and installing the ramp and injectors, write in the comments below.

1. First, remove the fuel rail from your vehicle.
2. Next, the ramp is laid on a flat surface, after which the wiring block is disconnected from the damaged injector. To remove it, you need to compress the spring mounting bracket and then disconnect the block.
3. Using a screwdriver, slide the metal retainer toward the fuel rail. It serves to fix the fuel nozzle. For some reason, many people remove the lock completely. There is no need for this. Just move it a little to the side.
4. Take the nozzle in your hand and rock it slightly to the sides. So it should come out of the fuel rail without any problems.
5. At the same time, be sure to check the current condition of the sealing rings of the fuel atomizer body.
6. The sealing ring of the nozzle spray element is checked in the same way. To do this, you need to pry both rings with a screwdriver and see if they are worn out.
7. In the case of fuel injectors, there is no need to change the O-rings when replacing the injectors themselves if they are in good condition. Only if you are going to reuse them, be sure to lubricate the rings with oil before installation. Motorized, of course.
8. When the nozzle is removed and the rings are replaced (or the old ones are left), you can begin installing new devices. The procedure is performed in reverse order.
9. Insert the nozzle into the hole on the fuel rail and secure it with the clamp.
10. Return the block with the wires to its place, and install the fuel rail in its rightful place.

Disconnecting the wiring block
Replacing injectors is not always the only and rational way to restore the functionality of fuel nozzles. Try cleaning them. This is not a difficult matter, but the savings are impressive .

How to clean the injectors from dirt on a VAZ 2108-VAZ 21099?

Preparation: 1) First, prepare the surface on which you will clean the injectors.

Note! In order to prevent the ingress of small particles of dirt and dust, it is best to clean the injectors on a clean surface, for example, laying down a clean rag!

2) Now take the phone charger in your hands, connect two wires to its terminal and wrap the whole thing with electrical tape.

3) Next, pick up two hoses, one of which is thin and the other thick. And then press the thin hose inside the thick one, and into the hole of the thin hose insert a small stick that comes from the spray head of the carburetor cleaning cylinder.

Note! Place a clamp on top of all the hoses so that all the hoses are tightly attached to each other!

4) Then connect the resulting hose structure to the fuel injector.

Note! After the nozzle is connected to the hose structure, tighten this place with a clamp so that the nozzle does not fly out when spraying. Also pay attention to how the nozzle is installed in the hose; carefully ensure that the spray part of the nozzle comes out!

5) And to complete the operation, connect the carburetor cleaning fluid to the spray head and as a result you should get the following thing:

Cleaning the injectors:

1) In order to start cleaning the injectors, they must first be removed. (For detailed instructions on how to remove them, read the article: “Replacing fuel injectors”)

2) Now, if you haven’t done this yet, then build absolutely all the things that were described in the “preparation” section. When all things are collected, place the cylinder along with the nozzle in a vertical position as shown in the figure below:

3) Then connect the charger to the outlet and then to the two terminals of the electrical connector of the injector, gradually begin to touch the tips of the two wires that come from the charging.

Note! When the wires touch the injector terminals, the injector will automatically begin to spray the liquid that is in the carburetor cleaning bottle, thereby cleaning the fuel injector. When cleaning, the pressure in the system will gradually drop, due to which the nozzle will stop working, in order to return the pressure to normal, press for a short duration of “2-4 seconds” on the spray head of the cylinder, indicated by the arrow in the bottom photo, and after which the pressure will return to normal !

Cleaning

There are two ways to clean fuel nozzles, each of which has its own nuances. Choose for yourself which one you like best or is more affordable, taking into account the available funds.

What is an injector - a modern replacement for a carburetor

An injector is a device that replaces the operation of a carburetor and consists of a fuel rail (rail) onto which injectors are attached. Under high pressure from the gasoline pump, fuel enters the rack, and from there the gasoline is distributed to the injectors. The injector nozzles, using rubber sealing rings, are inserted together with the rack into the engine block and inject fuel, which then ignites.

One of the main parts of the work in the injector is performed by the intake manifold. Its device includes a throttle valve, which is responsible for supplying air from the environment to the engine block.

How to remove and check injectors on a VAZ 2114 with your own hands

The “fourteenth” model of the domestic automaker represented by AvtoVAZ is equipped with injection power units . The motors have fairly good reliability indicators, but problems are rarely avoided. This is influenced by many factors.

If the Check Engine light comes on on the dashboard, and other symptoms of engine trouble are observed, it is likely that the injectors are clogged. In practice, cleaning injectors on a VAZ 2114 with your own hands is done quite often. It is not necessary to be an expert in the field of auto repair to understand the nuances of this event.

It is the issue of cleaning this fuel cell that our material today is devoted to.

How to remove VAZ 2109 injectors (injector) step by step

Removing the fuel rail

1. First of all, you need to remove the fuel rail.
2. Then place it on a flat surface, and then disconnect the wiring harness from the damaged injector. To dismantle it, compress the spring mounting bracket and disconnect the block.
3. Using a screwdriver, slide the metal retainer toward the fuel rail. It is designed to fix the fuel sprayer. For some reason, many car enthusiasts completely remove the lock. However, there is no need for this. Just move it a little to the side.
4. Take the nozzle in your hand and swing it to the sides. This way it will come out of the fuel rail without any problems.

Disconnect the wire block

What you need to know about injectors

The quality of the fuel used has a huge impact on the safety and efficiency of the injectors on your VAZ 2114. Alas, the quality of domestic fuel leaves much to be desired. If you regularly fill your car with low-quality gasoline, the injectors will not last more than 120 thousand kilometers.

Unscrew the fuel pipe

The optimal replacement frequency is about 80-90 thousand kilometers.

As for the cost, original injectors for the VAZ 2114 cost from 500 rubles apiece . Foreign analogues are more expensive, sometimes several times. But the price is largely justified by reliability and longer service life. Therefore, if possible, buy high-quality imported devices.

How to understand that you need to flush the injectors

Car manufacturers recommend cleaning every 30 thousand kilometers. Problems with the injectors will be indicated by corresponding errors on the on-board computer. The same thing will be shown by diagnostics of fuel equipment in a car service center.

But with a high probability, flushing is needed regardless of mileage, if at least three symptoms from the list appear in your car:

• poor starting (especially in winter);
• unstable operation at idle speed;
• reduction in engine power;
• slow acceleration;
• dips when pressing the gas pedal;
• increased fuel consumption.

How to extend the life of injectors

There are essentially two main ways to ensure that the fuel cells installed in your vehicle last as long as possible.

1. Use of additives. Special additives for increasing fuel quality and cleaning the system can be found in any automotive chemical store. They are poured into the gas tank. The additive costs quite little, so everyone can afford to buy it. But when starting to use additives, you should do this regularly, otherwise they will not be effective. Some people believe that additives only spoil the condition of the injectors. This statement may be true if low-grade or counterfeit chemicals are used. Good products, although they do not completely clean devices, can significantly extend their service life.
2. The second method is periodic flushing. Experts recommend performing the operation approximately once every 40 thousand kilometers traveled by your car. Some people do the cleaning themselves, while others turn to auto repair shops for help. For reference, we note that the cost of cleaning injectors at a service station will be from 1,500 rubles.

Malfunctions of VAZ 21099 - the injector also fails!

Regardless of the time of year outside, very often the car may simply stop starting, or begin to respond poorly to the gas pedal. In this case, all on-board computer sensors may not show errors. The causes of failure should be sought in the injector.

Usually the breakdown is associated with clogging of the fuel injector nozzles, which increases fuel consumption in the car and reduces traction. Due to the fact that the fuel does not enter in the quantity required for engine operation, the idle speed begins to float. For a VAZ, the normal value when the engine is idling in warm weather is 900 rpm. When starting in the cold season, the engine produces 1500 rpm; with proper operation, after 5–10 minutes they should drop to 900.

It is also worth paying attention to the throttle valve of the intake manifold - over time, black deposits appear on it, which prevents it from properly passing air. It is enough to clean the damper with a special spray and gently wipe with a cloth - the problem is eliminated!

Removing injectors

To clean the devices, they must first be removed from the vehicle. Let's figure out how to remove injectors on a VAZ 2114:

• Turn off the engine and let it cool for a while. This is necessary for your own safety;
• Disconnect the negative terminal from your car's battery;
• Remove the protective casing;
• Remove the air filter;
• The high pressure pipeline should be unscrewed from the nozzle and pump. It must be removed from the support bracket;
• You now need to unscrew the nozzle with a spanner wrench. Do this together with the puck;
• Be sure to disconnect the electrical connector and slide the lock located along the ramp;
• Manipulate all 4 injectors in the same way, which will allow you to eventually remove them;
• If the device is completely out of order, you will have to replace the injectors on the 8-valve VAZ 2114. If everything is fine with them, just clean them.

Location

You cannot start a conversation about instructions for removing injectors without first talking about the location of the object you are looking for.

How to Remove the Starter of a VAZ 2107 Injector Video... How to properly remove the starter on a VAZ-2107 One of the main mechanisms of any modern car is the starter. It is the one that starts the engine, so it is very important to maintain it in perfect condition. If the starter does not rotate after turning the ignition key, it will need to be dismantled and diagnostic and repair work performed. How…

At what Speed ​​to Shift Gears on a VAZ 2109... Gear shifting and lever position Manual transmission The positions of the gear shift lever are shown on its handle. Before engaging reverse gear, you need to lift the ring under the lever handle. When changing gears, depress the clutch pedal one hundred percent and then gently release it. It is not recommended to drive a car with one hand on the lever...

The injectors of VAZ 2109 cars are located on the fuel rail. There are 4 of them in total. This is due to the fact that each injector sprays fuel onto one separate cylinder. Since the nine has four cylinders, we conclude that the number of injectors is logical.

Cleaning

Useful cleaning agent
The procedure is not complicated, but try to do everything carefully and step by step.

1. Visually examine the condition of the item. If there are traces or signs of leakage, it is better to immediately replace the elements, since cleaning will definitely not have a long-term effect.
2. If the injector can be saved by stripping, remove the O-rings located on the body and nozzle.
3. Place them in acetone for a while. As an analogue, you can use regular gasoline. But do not forget that these are highly flammable mixtures, so there should not be any sources of even the slightest spark nearby.
4. Be sure to keep a fire extinguisher near you. Let you be the most careful and consistent person, accidents have never been canceled.
5. Keeping the injectors in acetone or gasoline will allow you to better clean all accumulated contaminants.
6. While the units are soaking, pay attention to the valve cover and ramp. It is advisable to clean them, as they act as sources of contamination.
7. The ramp is blown out with a conventional vacuum cleaner.
8. Now we take out the nozzles and start working directly with them.
9. Coke often forms on the nozzles, resembling resin in appearance and consistency. Be sure to get rid of these deposits.
10. The surface around the nozzle is cleaned with gentle movements of a pin or needle.
11. At this point, external cleaning can be considered complete.
12. Now the most difficult process is the internal “cleaning” of the elements. For this procedure, arm yourself with a tube, a syringe and a can of a substance intended for cleaning carburetors. It doesn’t matter that you have an injection car produced by our glorious automobile company AvtoVAZ. It is not difficult to purchase such a product, and it is cheap.
13. The product must be applied under pressure using a tube, simulating an injection. For each injector, perform several such manipulations. This will allow them to cleanse themselves and break through from within. As a result, the devices will be able to spray fuel liquid more evenly than before cleaning.
14. Be sure to give them some time to dry.
15. You should also replace the old O-rings with new ones. It is strongly not recommended to use the old ones, even if you clean them. Replace the seals every time you clean the injectors.
16. To delay the next cleaning as much as possible, and also to ensure long-term and efficient operation of the cleaned injectors, it is recommended to replace the mesh on the fuel pump, as well as the fuel filter.

VAZ 2114 drivers motivate the use of cheap gas stations by the need to save money . But if this is not stopped, clogged injectors will be only a small part of the problems your car will face due to poor fuel. And all the money saved on gasoline, plus the same amount, will be spent on repairs. Here is the price of cheap gas stations.

Injector flushing procedure

The contamination of injectors with tar deposits is primarily caused by the desire of companies that own gas stations to buy fuel cheaper and sell it at a higher price, and at the same time mix into it everything that increases the volume:

The whole process is discussed in detail in the article:

“How to flush an injection engine yourself.”

After consuming such a “cocktail”, a tarry coating forms

, which does not contribute to the normal operation of the engine.

The procedure for cleaning the nozzles and flushing the injector will consist of the following manipulations.

Before starting work, you need to stock up on special flushing liquid, new spark plugs and a syringe or powerful syringe. It is best to invite an assistant to perform this type of work. He does not need any qualifications in car mechanics; his task will be to maintain constant engine speed by pressing the gas pedal.

Algorithm

• Flushing liquid is mixed with gasoline in a volume of 1.5–2 liters;
• 
  connecting the intake manifold and the brake booster is disconnected
• A mixture of gasoline and rinsing is introduced into the adapter using a syringe;
• For the flushing mixture to react and clean the surface of the nozzle, it is enough to pause for 20 minutes. After this, the engine starts and idles. The speed must be constantly maintained with the gas pedal;
• After injecting the flushing solution, white smoke will come out of the hose along with pieces of black dirt. It will be greater the less frequently the injector is washed;
• 
  It is best to inject the washing mixture In this case, the quality of washing will be higher. After injecting the entire volume of flushing, the engine can be turned off;
• It is necessary to install new spark plugs only on a cooled engine, for which a certain time is allotted.

As a preventive measure, to reduce the degree of contamination of injectors, repair of the VAZ 21099 injector must be carried out every 5,000 km. mileage

, adding special additives with a cleaning effect to the gas tank as a preventive measure.

It is strictly not recommended to use solvent as a cleaning agent, as it will simply corrode the silicone on the injectors.

How to replace old injectors with new ones (in detail)

All four injectors are removed and installed identically, so we will consider replacing only one injector. The dismantling of the injectors was described in detail above, so we move on to the next stage - replacement.

1. First of all, we check the condition of the sealing rings of the fuel atomizer housing.
2. Likewise, check the O-ring of the injector spray component. To do this, pry up both rings with a screwdriver and inspect them for wear.

3. When it comes to fuel injectors, there is no need to change the O-rings when replacing the injectors if they are in good condition. But if you are going to reuse them, lubricate them with engine oil before installation.
4. When the nozzle is removed and the rings are replaced (or the old ones are left), you can begin installing new devices. The procedure is performed in reverse order.

5. Then we insert the sprayer into the hole located on the fuel rail and secure it with a clamp.
6. We return the block with the wires to its place, after which we install the fuel rail in place.
