Windshield washer nozzles on Nissan Almera Classic (B10) - it would seem a trifle, but their malfunction can cause a lot of inconvenience. Over time, the nozzles become clogged with dirt, lose their seal, or simply wear out, turning the liquid stream into a weak trickle or splashing in unpredictable directions. If you notice that the washer works “every once in a while”, liquid is pouring past the glass or the nozzles do not respond to the command at all - it’s time to replace them.

In this article we will walk through the entire process from diagnosing the problem to installation of new injectors, including the choice of original and analog parts, the necessary tools and typical mistakes that even experienced car owners make. We will pay special attention unique feature of fastening the injectors on the Almere Classic - they are secured not with standard latches, but through rubber seals, which often causes leaks if assembled incorrectly.

Signs of a faulty washer nozzle

Before you rush to change parts, make sure that the problem is in the injectors. Here are the key symptoms of their failure:

  • 🔍 Weak fluid pressure or a complete absence of jet when the pump is running (you can hear the buzzing of the motor in the tank).
  • 💦 Spraying to the sides — liquid splashes past the glass, onto the hood or on the sides.
  • 🔄 Uneven operation: one nozzle flows normally, the second one barely oozes.
  • 🚨 Constant leaks under the hood near the injector mounting area (wet marks are visible).
  • ❄️ Freezing of liquid in nozzles in winter - even when using “anti-freeze” (indicates a blockage).

If any of these signs appear, first check:

  1. Fluid level in the tank (sometimes the problem is a simple lack of washer).
  2. Pump performance - when the washer is turned on, the sound of its operation should be heard.
  3. Condition of supply hoses - they may become kinked or cracked.
⚠️ Attention! On Almera Classic Faulty injectors are often confused with a problem check valve in the washer system. If, after turning off the washer, liquid continues to drip from the nozzles, it is the valve that is to blame, not the nozzles.

Which injectors are suitable for Nissan Almera Classic (B10)

On Nissan Almera Classic (2006–2012) two types of washer nozzles were installed depending on the year of manufacture and configuration:

Nozzle type Original article Analogs (brand + article) Notes
Standard (before 2010) 28511-4M000 Febi 27380
Valeo 617208
Hella 8FL 355 371-041 		Fastening with rubber seals, without latches
Improved (after 2010) 28511-4M010 Bosch 1 987 402 035
Mitsubishi MR550909
Denso 550-0101 		With metal clamps, better hold pressure
Universal (suitable for all years) — Lynxauto LA-0198
SCT WA 010 		Requires adjustment of seals

When choosing, pay attention to:

  • 🔧 Nozzle material: plastic ones are cheaper, but wear out faster; metal (for example, Bosch) last longer.
  • 💧 Spray pattern: original nozzles give a fan jet, some analogues give a point jet (they clean glass worse).
  • 🔄 Completeness: the set must contain rubber seals (if they are not there, purchase them separately, article no. 28518-4M000).
💡

Before purchasing, remove the old nozzle and compare it with the new one - even original parts may differ in nozzle length by 1-2 mm, which will affect the direction of the jet.

Tools and materials for replacement

To work you will need:

Phillips screwdriver (PH2)

Flathead screwdriver or plastic puller

Pliers with narrow jaws

New washer nozzles (2 pcs.)

Rubber seals (if not included)

Silicone grease (eg Liqui Moly Silicon-Fett)

Rags and paper towels

Plastic clamps (2–3 pcs., in case of broken hoses)

Washer fluid for testing (1–2 l)

-->

Additionally, you may find it useful:

  • 🔦 Flashlight — The lighting in the engine compartment leaves much to be desired.
  • 🧴 WD-40 - if the injector mounts have become sour.
  • 📏 Ruler or caliper - to measure the seating depth of the new nozzles.

If you plan to flush the system, prepare:

  • 🚿 20 ml syringe with a tube (for bleeding hoses).
  • 🧼 Special cleaner for washer systems (For example, Hi-Gear HG5625).
⚠️ Attention! Do not use for rinsing plain water — deposits remain in the hoses and tank, which will quickly clog the new injectors. Only specialized liquids!

Step-by-step instructions for replacing injectors

Replacement process Nissan Almera Classic takes 30–40 minutes. Follow the instructions exactly step by step to avoid leaks or damage to the hoses.

Step 1: Removing old injectors

  1. Open the hood and find the injectors - they are located on a plastic casing under the windshield, on the edges from the center.
  2. Disconnect negative battery terminal (this is mandatory to avoid short circuit when working with electronics).
  3. Remove the plastic covers covering the injector mounts. They are held on by latches - pry them off with a flat-head screwdriver.
  4. Click on hose clamp (plastic clip) and remove it from the nozzle. If the clamp is broken, replace it with a new clamp.
  5. Gently pull the nozzle upward while rocking it from side to side. The rubber seal may “stick” - do not pull with force to avoid tearing it.
What to do if the nozzle cannot be removed?

If the nozzle does not budge, spray it WD-40 and wait 5-10 minutes. Then grab the nozzle pliers through rags (so as not to scratch it) and carefully twist it counterclockwise while pulling up. Do not use excessive force; the plastic housing may crack and splinters may be released into the hose.

Step 2: Preparing New Injectors

Before installation:

  1. Check the contents - the set should contain rubber seals (rings). If they are not there, use the old ones, but clean them first.
  2. Apply a thin layer silicone grease on the seal - this will facilitate installation and protect against sticking.
  3. If the new injectors have an adjustable nozzle, set it to the middle position (you will adjust it later).

Step 3: Installation and Connection

  1. Insert the nozzle into the socket all the way, making sure that the seal is seated evenly.
  2. Connect the hose and secure it with a clamp. Check that the hose is not kinked.
  3. Replace the plastic covers and snap them into place.
  4. Connect the battery terminal.

Step 4: Check and Adjust

Pour washer fluid into the reservoir and turn on the washer:

  • If the stream hits too low — bend the nozzle upward with a needle or toothpick.
  • If liquid flows to the sides — turn the nozzle left/right to the desired position.
  • If the pressure is weak, check tightness of connections (possibly sucking air).
💡

On Almera Classic After replacing the nozzles, be sure to bleed the system: turn on the washer 2-3 times for 3-5 seconds to remove air from the hoses.

Common mistakes and how to avoid them

Even experienced car owners make mistakes when replacing injectors. Here are the most common:

  • 🔧 Ignoring seals - without lubrication or with torn rings, the injectors will leak.
  • 🔄 Mixed up hoses — on Almere Classic, the left and right hoses sometimes differ in length. Mark them with a marker before removing them.
  • 💦 Using water for rinsing — leads to corrosion of metal parts of the pump.
  • 🔨 Tightening too much — the plastic nozzle body may crack.
  • ❄️ Replacement without checking the pump - if the pump is weak, the new injectors will also work poorly.

To avoid problems:

  • 📸 Take a photo location of hoses and fasteners before dismantling.
  • 🧪 Check the pump — if when connecting the hose directly to the pump (bypassing the nozzles) the stream is weak, the problem is there.
  • 🔍 Inspect the hoses for cracks - even a small gap negates the efforts to replace the injectors.
⚠️ Attention! On some Almera Classic after 2011 production, nozzles with electrically heated (article 28511-4M020). They cannot be replaced with regular ones - this will lead to an error on the dashboard (B2205).

How to extend the life of new injectors

To make your injectors last longer:

  • 🌡️ Use a quality washer — cheap fluids contain aggressive additives that corrode seals.
  • 🧹 Clean the nozzles regularly - wash them once every 3 months special cleaner (not water!).
  • ❄️ In winter, fill in anti-freeze in advance - do not wait until the first frost, when the liquid in the system has already thickened.
  • 🔧 Check the fastenings — tighten the hose clamps once a year.

If you often drive on dusty roads, install mesh filter at the inlet to the washer reservoir (article no. 28531-4M000). It traps sand and debris, which quickly clogs the injectors.

💡

To prevent blockages, add washer fluid to the washer reservoir every six months. 100 ml isopropyl alcohol — it dissolves deposits and prevents icing in winter.

FAQ: Frequently asked questions about replacing injectors

Is it possible to replace only one injector if the second one is working properly?

Technically yes, but not recommended. New and old nozzles will produce different pressures and jet shapes, which will impair visibility. In addition, if one injector fails, the second one will soon follow - their service life is approximately the same.

What should be the pressure from the injectors after replacement?

On Almera Classic a normal stream should hit 2/3 windshield height (approximately 30–40 cm from the nozzle). If the pressure is weaker, check:

  • Tightness of hose connections.
  • Pump functionality (supply voltage directly from the battery).
  • Make sure the filter in the tank is clean (it is located at the pump inlet).
What should I do if, after replacing the injectors, fluid pours into the hood?

This is a sign leaking seal. Remove the injectors and check:

  • Integrity of rubber rings (if torn, replace).
  • Correct installation - the seal should sit in the groove without distortion.
  • Availability of lubricant on the seal (use only silicone!).

If the leak remains, the injector mounting socket in the plastic casing may have cracked. In this case, it will need to be replaced or sealed with epoxy resin.

Will injectors from other Nissan models fit?

Yes, but with reservations:

  • From Nissan Note (E11) - article 28511-4M200, but the seals will need to be modified.
  • From Nissan Tiida (C11) - article 28511-4M100, are compatible in mounting, but give a narrower jet.
  • From Nissan Qashqai (J10) - not suitable due to different hose diameter.

It is better to use original parts or certified analogues from the table above.

Do I need to bleed the system after replacing injectors?

Definitely! Air remains in the hoses, which:

  • Reduces fluid pressure.
  • May cause "spitting" instead of a smooth stream.
  • Leads to false activation of the washer level sensor (if there is one).

For pumping:

  1. Fill the reservoir with liquid to the maximum.
  2. Turn on the washer for 5-7 seconds, repeat 3-4 times.
  3. Check that there is no air coming out of the hoses (put your hand to the connection with the nozzle).
