It is no secret that the visibility of the windshield directly affects the safety of driving a car. Sometimes the driver encounters difficulties - dirt, snow and midges get on the surface of the windshield. Then visibility is reduced several times, and even one object that the driver did not see can lead to the most unpleasant consequences. For example, at night, a pedestrian may appear from behind the side of the road, whom the motorist will notice at the very last moment. Only then do you realize how important it is to keep the glass clean. And so that there are as few such incidents as possible, all cars are equipped with special tools for cleaning the windshield. There are three of them: washer fluid, wipers and nozzles. The inoperability or absence of at least one of these parts precludes the possibility of cleaning the windshield. In today's article, we would like to pay attention to nozzles. Although they seem petty at first glance, without their presence, the glass will always be dirty.
At the moment, there are two types of these devices:
- Windshield washer jet nozzle (equipped for all cars of 80-90 years of release).
- Fan (considered more modern and efficient).
Indeed, windshield washers have become very popular lately. Ford Focus and many other cars are now equipped with just such devices. In general, the principle of operation of this part is the same, and it has not changed over the years. Today's windshield washer nozzle, like its "ancestors", sprays washer fluid at a certain part of the body with high pressure.
The difference between jet and fan devices is only in the spray technology. If the first one supplies liquid to the glass with a jet (hence the name), then the second one does it in small drops over the entire area of the windshield. Replacing the windshield washer nozzles is almost the same, as is their external design.
Pros and cons of these devices
The fan part, unlike the jet part, more evenly sprays the liquid over the glass surface. The latter option directs the agent only to a small area of the windshield, and only then the wipers smear it over the surface. The windshield wiper in this case makes an unpleasant creaking sound, while the fan analogues evenly process the glass, and the wipers quietly clean it to a shine in a matter of seconds. At the same time, the surface is practically not scratched, since everything happens without unnecessary resistance and with the best glide.
However, there are still things in which the windshield washer jet is superior to the fan. The fact is that the last element, when spraying liquid, completely deprives the driver of visibility, as it is scattered instantly by the entire layer around the perimeter of the windshield. For a few seconds the car is driven blindly. The driver has no choice but to trust his intuition and strong hands. A lot can happen in this short period of time. Therefore, here the windshield washer jet nozzle is clearly in the lead.
This article describes step by step how to properly replace the washer nozzles on the VAZ 2112. And the features of the maintenance and adjustment of these devices are also fully disclosed.
Some measures are proposed to improve the operation of injectors in general. Many motorists and professionals quite often face such a problem as the incorrect operation of the windshield washer nozzles.
In adverse weather conditions, any defect in the washer nozzles can bring quite a lot of trouble. Violation of visibility of the road is a very serious issue and all problems associated with it must be eliminated in advance.
In this case, replacing the washer nozzles of the VAZ 2112 is not a panacea for the above problem. It would be appropriate to consider it in conjunction with activities such as maintenance and adjustment of this node.
Nozzle detection
First of all, the car must be installed on a site convenient for work. The detection of the nozzle is carried out by its elementary inclusion.
Using the steering column switch lever, it is necessary to turn on and observe the operation of the nozzle.
List of malfunctions in the washer nozzles
- Washer fluid does not flow through the nozzle at all.
- Washer fluid pressure is very low.
- The jet of fluid supplied is directed to the side and does not provide full cleaning of the windshield.
- The washer fluid pump or its motor has failed.
- Washer fluid supply pipe damaged.
- The nozzle has mechanical damage.
- Nozzle nozzle clogged with foreign material.
- Injector adjustment out of order.
Causes of problems
Attention: In order to quickly determine the area where the defect is located, it is recommended to disconnect the washer fluid supply pipe from the nozzle and turn on the washer. If the pressure of the liquid supply is normal, then the whole problem is in the nozzle.
Dismantling the nozzle
In order to perform high-quality service, restore the efficiency of the nozzle or replace it, first of all, it is necessary to disconnect the wind pad or, as it is called in the common people, “jabot”.
Or rather, its upper part. To do this, you need a head for 10, flat and Phillips screwdrivers.
How to detach the upper part of the windshield
So:
- Using a 10 head, unscrew the two nuts located along the edges of the cladding.
- Next, we turn off the four screws with which the lining is attached. The screws are under the plugs.
- Then it is necessary to disconnect the noise insulation, which is attached to the wind window trim with six screws.
- Carefully remove the top of the windshield.
Having thus obtained access to the washer nozzles, we proceed directly to their dismantling.
To dismantle the injectors, you must:
- Disconnect the washer tube from the tee.
- Loosen the injector mounting screws as shown in the photo above.
- Remove nozzles.
Now you can perform all further operations with the nozzles. Assembly is carried out in reverse order.
Washing nozzles
Before replacing the nozzles, if they are thoroughly clogged, you can try to reanimate them. To do this, it is necessary to flush the nozzles.
The manual for servicing components and assemblies of a VAZ 2112 car does not indicate how to flush the nozzles. But, even for a novice motorist, this procedure is not very difficult.
For this you need:
- Soak the nozzle in white spirit for 3-4 hours.
- Clean the nozzle with a thin soft wire.
- Rinse the supply channel with water under pressure.
- Blow out the channel with compressed air.
If necessary, the procedure must be repeated several times. In particular, on a VAZ 2112 car, flushing the nozzles does not take much time.
And it is not the price of the issue that worries in this case. Much more important is the knowledge and experience that we gain in the process of performing these works.
Attention: Do not clean the nozzle with a sewing needle. The tip of the needle may break and severely jam the washer fluid passage.
Nozzle adjustment
If you managed to flush the nozzles on your VAZ 2112 car yourself, then you can confidently cope with the task of adjusting them. To do this, you need to understand a little about the design features of this device.
On a VAZ 2112 car, two types of washer nozzles are used - jet and fan. In turn, jet nozzles can be: single-jet, double-jet and four-jet.
This terminology is defined by the way washer fluid is sprayed onto the windshield. In the jet nozzles, at the washer fluid outlet, a hinged socket is installed.
This is a small ball with a through hole. Fan nozzles are equipped with a narrow slot-like socket.
And now let's start adjusting the nozzles with our own hands:
- The direction of the jet in the jet nozzles is adjusted by turning the hinged socket.
- We insert a thin wire into the hole of the ball and turn the bell in the right direction.
- Adjustment of fan nozzles according to their design is carried out only in a vertical position, the socket rises or falls to the desired direction. But it doesn't matter, turning them left or right is also possible.
And, in general, no instruction can forbid you to introduce any technical solution that improves the operation of car units.
Nozzle maintenance
To ensure the smooth operation of the injectors, periodic attention is required. An extra inspection of the injectors will not hurt.
If the nozzles have not been turned on for a long time, then they must be checked for operability. Clean and adjust if necessary.
In the winter season, it is imperative to use an anti-freeze washer fluid. Freezing nozzles leads to their wear and premature failure.
If you follow the recommendations suggested in this article, then you will not need to replace the VAZ 2112 washer nozzle for a long time. And the windshield will wash as the video shows.
Clogged windscreen washer nozzles are a fairly common problem. Typically, the source is automotive wax or varnish, which creates a blockage at the top of the nozzle, preventing fluid from spraying onto the windshield. Despite all the inconveniences, this problem is quite simple to fix. If it is not possible to clear the blockage, there is nothing difficult in replacing the nozzle either.
Steps
Removing blockages in windscreen washer nozzles
-
Listen to the washer pump. Before you start cleaning the nozzles, turn them on and listen for the low hum of the washer pump. If the nozzles are clogged, then, despite the lack of spray, you will still hear the pump.
- If you're not sure the pump is on, have a friend stand near the hood and listen to it from outside the car.
- If the pump cannot be heard, it must be replaced.
-
Inspect nozzles for external blockage. Locate the jets at the top of the hood, near the windshield, and look for the cause of the blockage. Often, automotive wax or varnish can clog the nozzles of the nozzles, thereby preventing the liquid from spraying correctly.
- Wipe off any wax or varnish that interferes with the nozzles.
-
Take a pin to clear a deep blockage. If removing the blockage does not clear the nozzle enough to spray the washer, try clearing the nozzles with a pin or needle. Insert a pin into all holes of the nozzle, after each time cleaning it from the dirt to be removed.
- Don't push the pin too deep or you won't be able to pull it out later.
- Do not push the needle too far into the back of the nozzle to avoid breaking it or the nozzle inadvertently.
-
Pass the wire through the nozzle. If the pin is too short to clear the blockage in the injector, get under the hood and disconnect the hose at the bottom of the injector. After that, pull a thin wire through the bottom of the nozzle up to the nozzle. If the nozzle has multiple holes, run the wire through several times until both holes are clear.
- Guitar strings are ideal for this task as they are stiff enough to go through the jet.
- You can also use stripped electrical wire.
Soaking or replacing nozzles
-
Disconnect the hose from the bottom of the nozzle. The rubber hose at the bottom of the nozzle is held in place solely by the pressure it exerts on the nozzle, so it should come off with relative ease.
- Squeeze the hose with your index finger and thumb in the area of the nozzle and pull it towards you to remove it.
- If the hose suddenly gets stuck, take the pliers and twist it back and forth to free it.
-
Use pliers to pry the nozzle out of the hood. The windshield washer nozzles are fixed with plastic latches. Take the pliers and press the valves into the nozzle, and then pull them up.
- When the valve is pressed, the nozzle should be easily pulled out of the hole in the hood.
- Do not be afraid to break the valves if you decide to completely replace the nozzles. Otherwise, try not to damage them.
-
Pull the injectors out of the hood. Lower the hood again and pull up on the nozzle, pulling it out of the hole. If you have already taken care of the valves, then the nozzle should pop out of the hole without any resistance.
- If the injector gets stuck somewhere, open the hood and squeeze the clips with pliers to release them again.
- Be careful not to damage the paint on the hood while you are pulling out the injectors.
-
Soak the jets in a bowl of vinegar. You may be able to clear clogged jets by soaking them in a bowl of vinegar for a while. Move the nozzles a little in the vinegar so that it certainly penetrates the blockages. Take the jets out of the vinegar after a few minutes and rinse them.
- Try blowing into the nozzle after rinsing to see if the blockage has cleared.
- If the nozzle has been cleaned, return it back to the vehicle.
-
Install new windshield washer nozzles. It doesn't matter if you bought new windshield washer nozzles or are returning cleaned ones, the installation process remains the same. Insert the nozzle through the hole in the top of the hood with the nozzles facing the windshield. When they are at the very bottom, the plastic clips will spread out to the sides and hold the nozzles in place.
- Once the nozzle is in place, connect the washer to it.
- Start the engine and turn on the new injectors to make sure they are working properly.
Inspection and repair of windshield washer tubes
-
Inspect the tubes coming from the washer fluid reservoir. If the windshield washer jets are not spraying washer fluid onto the windshield, the problem may be a broken or kinked hose from the washer fluid reservoir to the washer fluid. Inspect tubing for blockage or damage.
- Start your inspection at the reservoir and follow the pipes all the way to the nozzles attached to the hood.
- Look for signs of leaks, bends, and other potential damage.
Factory-installed jet windshield washer jets do not always clean the surface properly. They quickly clog, and the very efficiency of work leaves much to be desired. The best option is fan-shaped windshield washer nozzles.
Windshield washer jets
What are their features? How to choose these nodes for a car? What installation features should you be aware of? Let's consider these points in more detail.
Purpose
Fan nozzles have a more advanced design, which implies a "drip" distribution of liquid over a larger area of \u200b\u200bthe windshield, which ensures that the wipers clean the surface quickly and efficiently. In contrast to products of the jet type, where the supply occurs in 2-3 jets to a certain place.
Pros and cons of windshield washer fan nozzles
Before buying and installing fan nozzles, it is important to study their features, positive and negative qualities.
The advantages of true injectors include:
1. Efficient removal of contaminants from the glass surface. Thanks to high-quality spraying, it is easier for wipers to cope with dirt, dust and even dried insects.
2. Full windshield processing, thereby reducing the risk of scratches. In the case of jet jets, the wipers travel a certain distance on dry glass.
3. Reduced washer fluid consumption. When operating a car in the cold season, you have to buy an “anti-freeze” - a special liquid that can withstand low temperatures. Fan nozzles allow you to reduce the consumption of expensive composition, and save money in your wallet.
4. The wipers at the first stroke move on a wet surface. As a result, contaminants are better removed, and not smeared on the glass, as is usually the case.
Disadvantages of fan nozzles:
1. After liquid is supplied through the jets, the glass is covered with many small drops. At the same time, visibility deteriorates until the wipers pass the first cycle. This feature is usually what annoys car owners who prefer jet nozzles. We must not forget that the loss of control of the traffic situation, even for a fraction of a second, can lead to an accident.

2. Fan type jets freeze faster in the cold. That is why it is important for car owners living in the northern regions to think about heated nozzles.
Rules for choosing fan nozzles for windshield washer
The best option is to buy original jets that are suitable for working on a particular vehicle. A large number of companies are engaged in the production of such products, so it is not difficult to choose a jet for a specific model and brand.
If the original part could not be found, an alternative is available - universal fan nozzles. Their peculiarity lies in the possibility of mounting on a whole group of makes and models of vehicles. In extreme cases, minor structural modifications may be required.
As an option - purchase jets from Volvo or Ssang Yong manufacturers (catalog numbers - 30655605 and 7845009010). If you choose from two types, the details of the Korean brand can boast more versatility. Their advantages are low cost and the ability to install cars on a whole group - Mazda, Toyota, Daewoo and others.
Which check valve to choose?
The factory design of the washer often does not provide a check valve. The task of the mechanism is to protect against the flow of the working fluid back into washer reservoir when power is removed from the pump. At the same time, the valve guarantees continuous cleaning of the windshield. Structurally, this is an ordinary ball with a spring that blocks the exit from the jet in the absence of pressure.
check valve
It is allowed to use fan nozzles without installing a valve. But in this case, an alternative solution is required - delaying the movement of the wipers in relation to the fluid supply. It can be organized in two ways - using an electrical circuit or mechanical devices. Thanks to this alteration, the washer composition travels the distance from the liquid container to the jets until the wipers start working.
The following types of valves can be used:
- Check valves for VAZ-2108 or 2109.
- Foreign production (for Volvo or Toyota).
- Ready-made tee with a valve from Mitsubishi.
- Check valve from the aquarium compressor. Advantages - reliability and efficiency.
The device is sold in a pet supply store. Here you can also purchase a piece of silicone tube to create nozzles. Such a product withstands elevated temperatures and has a long resource (even in comparison with the factory tubes installed on the VAZ).
How to mount fan nozzles?
Contrary to popular belief, windshield fan nozzles are easy to install. The algorithm of actions is as follows:
1. Remove the upholstery (thermal insulation) mounted on the hood (if provided). Be careful not to break the fragile plastic caps. Get them with a special tool or with a pair of screwdrivers.
2. Remove the foam pads that are held on by double-sided tape (you will need a new piece during the installation process).
3. Discard the overlays on the plastic elements.
5. Remove old devices. They can be held on the frame or hood using plastic fasteners or nuts.
6. Install the fan jets (without fastening) and bring the nozzles to them.
7. Connect the check valves to the pipelines and nozzles of the jets, then fix them.
8. Check that the device is working properly and the droplet spray is falling on the windshield. Fasten the jets.
Video on installing fan nozzles.
Please note that windshield washer fan nozzles for VAZ cars or other cars often require adjustment after installation, but they do not have an angle of inclination (it seems that now there are adjustable nozzles, who knows, write in the comments).
To change the angle of inclination, height or direction, it is worth adjusting the base of the jets using a notch, trimming or building up the base. Special gaskets made of plastic or rubber may be required here. It is important that as a result of the adjustment, the liquid covers the glass and does not go beyond its borders.
Fan nozzles of a windshield washer of a motor vehicle are characterized by many advantages. For this reason, many drivers install them in place of standard fixtures.
Fan windshield washer nozzles - advantages and disadvantages
The main advantage of fan-type devices is that they apply a special washing composition to the glass with a powerful front of small droplets, and not in separate streams, as is customary in classical devices. Due to this, the drops immediately cover almost the entire windshield.
It is clear that such a supply is very economical, and most importantly, it provides high-quality cleaning of the main glass of the car for the driver, through which he watches the road.
There are such advantages of using fan devices:
- Removal of insects, plaque of different composition and any solid structure contaminants from the windshield at a high level of quality, due to the fact that a large area is washed evenly (“blind” zones on the glass are practically absent).
- The glass cleaner brushes make their first movement on the surface moistened with the cleaning liquid. Thus, the brushes immediately begin to remove dirt, and not just smear it on the glass.
- The consumption of the composition for removing contaminants, which costs a lot of money, is reduced.
- The risk of scratches on the glass caused by the sweep of a dry brush is significantly reduced.
The disadvantages of the described devices experienced motorists include the following facts:
- Applying the cleaning agent to a large area of the glass surface temporarily deprives the driver of adequate visibility of the road in front of the vehicle. Such a loss of visibility does not last long, but it “annoys” many motorists, which is why they refuse to install fan nozzles.
- High susceptibility of liquid fan devices to freezing. In the conditions of the Russian winter, such a disadvantage is of great importance. You can cope with it by installing nozzles, which are equipped with a device for heating them.
Choice of Fan Design Nozzles
The optimal situation is when you buy branded fan devices that are made for a specific make and model of a machine. Now many manufacturers produce original fan nozzles for specific vehicles. In other cases, you will have to choose such devices that are classified as universal, that is, suitable (initially or with minor technical modifications) for your car.
Universal nozzles now include products with catalog number 7845009010 from the company Ssang Yong and 30655605 from Volvo. The latter are standard for Volvo S80. There is no difference between them, except that Korean devices are almost half the price of more prestigious ones. Volvo. According to reviews of Russian motorists, these nozzles are suitable for vehicles of various automakers, in particular the following:
- Mazda;
- Subaru;
- Toyota;
- Daewoo and many others.
Features of mounting fan nozzles
Sometimes, to install universal windshield washer fan nozzles, they must be adjusted in height, using insulating tape to seal (this is required in cases where the spray area is excessively large). Also, motorists often have to undermine the body of the nozzles if their lower part is wider than standard inkjet devices in their parameters.
