Nissan Almera G15 is a popular sedan that is valued for its reliability and unpretentiousness. However, even in such a proven model, little things wear out over time, which sometimes cause a lot of trouble. One of them is windshield washer nozzles. At first glance, this is an insignificant detail, but when they become clogged or broken, driving in rain or snow turns into an ordeal. The driver loses visibility, and attempts to manually clear the glass distract from the road.

In this article we will look at everything you need to know about washer nozzles on Almera G15: how they work, why they stop working, how they are diagnose, clean or replace on your own. We will also compare original parts with analogues and give advice on selection. If you are faced with the problem of weak spray or complete absence of liquid on the glass, you will find a solution here.

The design and principle of operation of washer nozzles on Nissan Almera G15

Windshield washer nozzles (or nozzles) Almera G15 - These are small plastic sprayers that are attached to the hood under the windshield. Their task is to evenly distribute the washer fluid over the surface of the glass for the wipers to work effectively. In the model G15 (2012–2019) injectors used fan type, which create a wide spray pattern rather than a jet.

How it works:

  • 🔋 When you press the washer lever, it turns on electric pumplocated in the washer fluid reservoir.
  • 💦 The pump creates pressure, and the liquid flows through the hoses to the nozzles.
  • 🌀 Installed inside the nozzle spray element (most often a plastic mesh or membrane), which splits the flow into small droplets.
  • 🌊 The liquid evenly covers the glass, after which the wipers remove dirt.

On Almera G15 the injectors are attached to the hood using plastic latches or screws (depending on the year of manufacture). Hoses are connected through quick-release fittings. Important: in some configurations nozzles with heated - this is relevant for regions with cold climates, where liquid can freeze in the nozzles.

Signs of injector failure: when is it time to clean or replace

Washer problems rarely occur suddenly; they are usually preceded by noticeable symptoms. If you ignore the first signs, over time the injectors will completely fail and will have to be replaced. Here's what to look for:

Main symptoms of malfunction:

  • 🚫 No spray — liquid does not flow onto the glass, although the pump is running (the sound of it turning on is heard).
  • 💧 Weak or uneven pressure — the jet hits only one point or the spray is too weak.
  • 🌀 Distorted torch shape — instead of a fan spray, the liquid flows in a stream or splashes to the sides.
  • ❄️ Freezing of liquid in nozzles - relevant in winter if the nozzles are not heated.
  • 🔊 Extraneous sounds — a whistle or hissing sound when the pump is running may indicate a blockage in the hoses or the nozzles themselves.

Most often the problems are caused clogged nozzles (dust, dirt, deposits from poor-quality washer fluid) or mechanical damage (cracks in the body, wear of the spray element). Less often to blame pump or broken hoses.

⚠️ Attention: If fluid does not flow from any of the injectors and the pump does not make sounds when turned on, the problem may be fuse (usually F30 (10A) in the block under the steering wheel) or relay. Check them before disassembling the injectors!

Diagnostics: how to determine that the injectors are to blame

Before removing the injectors, make sure that they are the problem. Carry out simple diagnostics:

  1. Check fluid level in the tank. Sometimes the problem lies in the banal lack of washer.
  2. Listen to the pump. When you press the washer lever, you should hear a slight buzzing sound from the reservoir area (under the front bumper). If it is not there, the problem is in the pump, fuse or wiring.
  3. Disconnect the hose from the nozzle and check whether fluid flows when the washer is turned on. If yes, the nozzle is clogged; if not, the problem is in the hose or pump.
  4. Replace the injectors. If a non-working nozzle starts working in another place, and the second one stops spraying, the nozzle itself is to blame, and not the supply hose.

If the diagnostics confirm that the nozzles are to blame, you can proceed to repair them. cleaning or replacement. In 80% of cases, simple washing helps, but if the spray element is damaged, new parts will need to be installed.

Is the washer reservoir valve open?

Is the pump running (can you hear a sound)?

Are the hoses intact (are there any cracks or kinks)?

Is the liquid in the reservoir clean (is there any sediment)?

Is fuse F30 (10A) good?

How to clean washer nozzles on Nissan Almera G15 without removing

If the blockage is not severe, you can try to clean the injectors without dismantling them. This method is suitable for prevention or if the spray has weakened, but the liquid is still flowing. You will need:

  • 🧴 Needle or thin wire (with a diameter of no more than 0.5 mm).
  • 💦 Syringe with tube (for example, from a drip).
  • 🧼 Special cleaner for injectors or regular vinegar (diluted 1:1 with water).

Step by step instructions:

  1. Remove the washer reservoir cap and add cleaning fluid (vinegar solution or injector cleaner).
  2. Press the washer lever several times to force fluid through the system. Wait 10–15 minutes.
  3. If the blockage remains, carefully clean the nozzle hole with a needle. Don't press too hard — the spray element may be damaged!
  4. Using a syringe with a tube, apply the cleaner directly into the nozzle nozzle. Repeat 2-3 times.
  5. Flush the system with clean water by pressing the washer lever 5-6 times.

If after cleaning the spray is restored, but after some time the problem returns, it means that the blockage is deep or the spray element is worn out. In this case you will need replacing injectors.

💡

To prevent blockages, use high-quality washer fluid without sediment and rinse the system once a season with water with the addition of citric acid (1 teaspoon per 1 liter of water).

Replacing washer nozzles with Nissan Almera G15: step by step instructions

If cleaning does not help, you will have to install new injectors. The procedure is simple and takes no more than 30 minutes. You will need:

  • 🔧 Flat head screwdriver or a plastic clip remover.
  • 🔨 Phillips screwdriver (if the injectors are secured with screws).
  • 🛠️ New injectors (original or analogues, see table below).
  • 🧴 Silicone grease (for O-rings).

Sequence of actions:

  1. Open the hood and find the injectors. They are located on a plastic panel under the windshield, on either side of the center.
  2. Disconnect the fluid supply hoses. To do this, press the lock and pull the hose to the side.
  3. Remove the injectors:
    • If they are attached to latches - use a screwdriver to pry them off from the side and pull them up.
    • If on screws - Unscrew the fasteners with a Phillips screwdriver.
  • Install new injectors in reverse order. Don't confuse left and right — they may differ in spray angle!
  • Connect the hoses until the lock clicks.
  • Check the washer operation by pressing the lever. Adjust spray direction if necessary (see next section).
    • ⚠️ Attention: When installing new injectors do not use excessive force when tightening screws or snapping clips. The plastic housing may crack and the injector will begin to leak!

    On Almera G15 after 2016, some trim levels are equipped with heated injectors (article no. 28540-JM00A). They cannot be replaced with regular ones - this will lead to an error in the system and failure of the washer in winter.

    Adjusting the spray direction: how to set the nozzles correctly

    Even new injectors can spray fluid in the wrong places. For example, the jet may hit too low (on the hood) or high (outside the glass). On Almera G15 The spray direction can be adjusted without tools.

    How to adjust:

    1. Turn on the washer and pay attention to where the fluid hits.
    2. Paste needle or toothpick into the nozzle hole and carefully pry the spray element in the desired direction:
      • If the liquid rushes too low — lift the sprayer up.
      • If too high - lower it down.
      • If the jet goes to the side — move the sprayer to the left or right.
  • Check the result by turning on the washer again. Repeat the adjustment if necessary.

    • Some injectors (for example, original Nissan) have adjusting screw on the side. In this case, it is enough to turn it with a screwdriver to change the spray angle.

    💡

    The ideal spray direction is in the middle of the windshield, slightly above the wiper line. This provides maximum fluid coverage with minimal flow.

    Selection of injectors: original vs analogues, articles and prices

    On Nissan Almera G15 Two types of nozzles are installed:

    1. Regular (without heating) - article 28540-BM40A or 28540-JM000.
    2. Heated - article number 28540-JM00A (for versions with winter package).

    Original parts can be replaced with analogues from trusted brands. Below is a comparison table:

    Type Article Brand Approximate price, ₽ Notes
    Original (without heating) 28540-BM40A Nissan 1 200–1 500 Guaranteed compatibility, long service life
    Analogue 28540-JM000 Febi (28540) 400–600 Good quality, often installed at service stations
    Analogue 8K0 955 985 A Hella 500–700 Universal, suitable for many models

    When choosing analogues, pay attention to:

    • 🔍 Mounting type (latches or screws).
    • 🌡️ Presence of heating (if it was in the original).
    • 📏 Spray angle - it must match the original.

    Where to buy:

    • 🛒 Official dealers Nissan - original parts, but expensive.
    • 🔧 Auto parts stores (For example, Exist, Autodoc) - a wide selection of analogues.
    • 🌍 Internet platforms (AliExpress, eBay) - cheaper, but there is a risk of running into a fake.
    How to distinguish an original nozzle from a fake?

    Original parts Nissan have:

    - Clear marking of the article number on the case.

    - Smooth plastic without burrs.

    - O-rings made of soft rubber (do not harden in the cold).

    - Brand logo on packaging with a hologram.

    Counterfeits often feature dull plastic, crooked seams, and lack of markings.

    Common replacement mistakes and how to avoid them

    Even something as simple as replacing injectors can turn into problems if mistakes are made. Here are the most common of them:

    • 🔧 Left and right injectors mixed up. On Almera G15 they may look the same but have different spray angles. Always check the label (L - left, R - right).
    • 💧 Loose hose connection. If the latch is not fully latched, fluid will leak or not flow at all.
    • 🧴 Using aggressive cleaners. Solvents or acetone can damage the plastic of injectors and hoses.
    • ❄️ Replacing heated injectors with regular ones. This will lead to an error in the system and failure of the washer at low temperatures.
    • 🔨 Screws are over-tightened. The plastic body of the injector may crack and it will have to be replaced again.

    To avoid problems:

    • 📸 Take a photo location of injectors and hoses before removal.
    • 🧴 Use silicone lubricant for o-rings - this will prevent leaks.
    • 🔧 Check the washer operation immediately after installation, so that you don’t have to disassemble everything again.
    ⚠️ Attention: If after replacing the injectors there is still no fluid flow, check filter in the washer reservoir. It is located at the pump inlet and often becomes clogged with dirt. It is enough to rinse it with water or replace it.

    FAQ: answers to frequently asked questions

    Is it possible to drive without working washer nozzles?

    Technically yes, but this unsafe. The traffic regulations (clause 4.3 "List of faults") indicate that it is prohibited to operate the vehicle if they do not work provided by the design glass washers. The penalty for this is 500 ₽ (Article 12.5 of the Administrative Code). In addition, without a washer, you risk losing your view in the rain or when dirt gets on the glass.

    Why do injectors freeze in winter, even if the fluid does not freeze?

    There are several reasons:

    1. Remained in the system water after summer use. It freezes even at −5°C.
    2. Injectors are not heated, and the liquid in the nozzle has time to cool.
    3. Used poor quality washer with a low freezing point.
    4. Clogged injector impairs circulation liquid and it stagnates.

    Solution: Flush the system isopropyl alcohol (diluted 1:1 with water), then fill with a high-quality winter washer (for example, Liqui Moly Antifrost).

    How often should washer nozzles be replaced?

    Injector service life Almera G15 — 50–80 thousand km or 3–5 years. However it depends on:

    • The quality of the washer fluid (cheap compounds leave a residue).
    • Frequency of use (injectors wear out faster in the city).
    • Operating conditions (dust, dirt, frost reduce the service life).

    Signs that it is time to change the injectors: constant blockages, cracks in the body, inability to adjust the spray pattern.

    Can I install injectors from another Nissan model?

    Theoretically yes, but only if they match:

    • Type of fastening (latches/screws).
    • Hose fitting diameter.
    • Spray angle.

    For example, injectors from Nissan Note (28540-4M000) are suitable in size, but may differ in the shape of the torch. It is better to choose a part with the same article number as the original.

    What should I do if, after replacing the injectors, fluid flows under the hood?

    Most likely the problem is:

    1. Loose connection of hoses — check the clamps and, if necessary, crimp them with pliers.
    2. Cracked injector body - if you tighten the screws, you will have to install a new one.
    3. Damaged O-ring - Lubricate it with silicone or replace it.

    Also check if the fluid supply hose is kinked - this could create excess pressure in the system.
