Windshield washer nozzles for Nissan Almera Classic: diagnostics, replacement and selection of the best analogues

Windshield washer nozzles on Nissan Almera Classic (B10) - it would seem a trifle, but their malfunction can cause a lot of inconvenience. In rain or snow, a poorly cleaned windshield makes driving a challenge, and ignoring the problem often leads to scratches on the glass or even an accident due to limited visibility. Owners Almeri Classic encounter typical problems: clogged nozzles, leakage of liquid or complete failure of the nozzles. In this article, we will look at how to diagnose a malfunction, what spare parts to choose for replacement, and how to carry out repairs yourself - without contacting service.

Feature Almera Classic (2006–2012) is that its washer system is structurally simple, but has “weak points”. For example, original injectors 28550-4M000 often become clogged due to poor quality washer fluid or corrosion of internal channels. In this case, replacement takes no more than 30 minutes, and the cost of new parts starts from 300 rubles per piece. We have collected proven repair methods, current spare parts numbers and cleaning life hacks - so that your overview remains clear in any weather.

Signs of malfunctioning washer nozzles on a Nissan Almera Classic

The first signal about problems with the injectors is uneven spray of liquid or its complete absence when you press the washer lever. On Almera Classic The most common symptoms are:

• 💧 The liquid flows in a stream instead of spraying (nozzles are clogged or the sprayer is worn out).
• 🔄 One nozzle works, the second does not (problem with the tube or valve).
• 💦 Liquid leaks under the hood (cracks in the body or wear of the seals).
• 🚫 Complete lack of response to turning on the washer (pump malfunction or broken wiring).

On Nissan Almera Classic Fan-type nozzles were installed from the factory, which lose their tightness over time. If no fluid comes out at all, first check:

1. Fluid level in the tank (sometimes the problem is solved by topping up).
2. Condition of hoses for kinks or cracks.
3. Pump performance (listen to see if the sound of its operation is heard when you press the lever).

⚠️ Attention: If liquid does not flow into any nozzle, but the pump is humming, the filter in the tank is most likely clogged or the main hose is pinched. On Almera Classic it runs along the left pillar and often rubs against the edge of the hood.

Which injectors are suitable for Nissan Almera Classic: original vs analogues

Original injectors for Nissan Almera Classic (B10) have article number 28550-4M000 (left) and 28551-4M000 (right). Their average price in official catalogs is 800–1200 rubles per pair. However, many owners prefer analogues, which are cheaper and sometimes even more reliable.

Manufacturer	Article	Price (per piece), ₽	Features
Nissan (original)	28550-4M000 / 28551-4M000	800–1200	Exact fit, but plastic will crack over time.
Denso	550-0101	450–600	Japanese quality, compatible with most models Nissan.
Febi Bilstein	28550	300–450	A budget option, but there are defective seals.
Mitsubishi (cross compatible)	MR550005	500–700	Suitable for fastenings, but may require adjustment of hoses.

When choosing analogues, pay attention to spray type: on Almera Classic It is optimal to use fan nozzles with a spray angle of 90–120°. Cheap Chinese options (for example, nameless ones with AliExpress) often have imprecise nozzle geometry, which causes fluid to hit the body pillars or mirrors rather than onto the glass.

Important: On restyled versions Almera Classic (2010–2012) sometimes nozzles with article number were installed 28550-4M010 - they are visually identical, but have a different nozzle angle. When replacing, this is not critical, but may require adjusting the direction of the jet.

Step-by-step instructions for replacing injectors on a Nissan Almera Classic

Replacing injectors with Almera Classic does not require special tools - just a flat screwdriver and pliers. The work is completed in 20–30 minutes even without experience. Algorithm of actions:

1. Preparation: open the hood and find the injectors (they are located on the plastic casing under the windshield, on the sides of the wipers).
2. Removal: Carefully pry the injector retainer with a flat screwdriver and pull it up. The hose is disconnected by pressing the plastic clip.
3. Installing new ones: Slide the new injectors onto the hoses until they click and secure them in their sockets.
4. Check: turn on the washer and adjust the direction of the jet with a needle (if necessary).

On Almera Classic The injector mounts are plastic, so when removing, do not use excessive force - they may break. If the retainer is cracked, it can be replaced with a similar one from other models Nissan (for example, from Note or Tiida).

⚠️ Attention: When installing new injectors, do not confuse the left and right ones - they are mirrored! There are markings on the original parts L (left) and R (right). If you mix it up, the jet will hit the body pillar.

How to clean clogged injectors without replacing them

If the injectors are clogged but have no mechanical damage, they can be restored. On Almera Classic Most often, nozzles become clogged due to:

• 🧴 Using low-quality washer fluid (with sediment or particles).
• 🍂 Dust or leaves getting into the tank.
• 🔥 Corrosion of internal channels (if water was used instead of special fluid).

For cleaning you will need:

1. A needle or thin wire (0.3–0.5 mm in diameter).
2. Syringe with a tube.
3. Special liquid for cleaning injectors (for example, Liqui Moly Drosselklappen-Reiniger).

Procedure:

1. Remove the injectors (as described in the previous section).
2. Wash the nozzles outside and inside with cleaner, and clean with a needle.
3. Pour the cleaner into the syringe and pass it through the nozzle under pressure 2-3 times.
4. Blow with compressed air (for example, a tire pump) and reinstall.

If after cleaning the stream remains weak, the problem may be clogged filter in the tank. On Almera Classic it is located at the bottom of the tank and is a fine mesh. It is enough to remove the tank (by unscrewing 2 bolts) and wash it.

Adjusting the direction of the jet: why the liquid hits past the glass

A common complaint from owners Almera Classic — liquid from the injectors gets onto the body pillars or mirrors, but not onto the glass. This happens due to:

• 🔧 Incorrect installation of injectors (left/right mixed up).
• 🚗 Deformation of fastenings after an accident or careless repair.
• 🔄 Wear of the seals, which causes the nozzle to “walk” in the socket.

You can adjust the direction of the jet in two ways:

1. Mechanically: pry the nozzle with a needle and turn it in the desired direction. On original injectors Nissan the nozzles rotate 10–15°.
2. Substrate: if adjustment does not help, place a thin washer (1–2 mm) under the base of the nozzle to change the angle of inclination.

On restyled Almera Classic (2010+) sometimes replacing the injectors with Denso 550-0101 - they have a wider adjustment angle. If the problem persists, check hood geometry: after minor accidents it can sag, which changes the angle of incidence of the liquid.

What to do if adjustment does not help?

If after all the manipulations the liquid continues to flow past, the problem may be in the deformation of the plastic casing under the hood (where the injectors are attached). In this case you will have to:

1. Remove the casing (unscrew the 4 bolts at the edges).

2. Level its shape using a hair dryer (heating + manual editing).

3. Reinstall and re-adjust the injectors.

This method requires caution, as if overheated, the plastic may lose its strength.

Typical replacement mistakes and how to avoid them

Even something as simple as replacing injectors can result in new problems if mistakes are made. Here are the most common mistakes owners make Almera Classic:

• 🔌 No power cut: If the ignition is turned on, the washer pump may operate spontaneously when manipulating the hoses, which will lead to flooding of the electronics.
• 🔄 Hose entanglement: on Almera Classic The hoses of the left and right injectors sometimes differ in length. If they are swapped, the liquid will flow unevenly.
• 💧 Using water instead of washer: This leads to corrosion of the nozzles and freezing of the system in winter. Even in summer it is better to use a specialized liquid.

Another common mistake is failure to check tightness after installation. If the hose is not fully seated on the injector fitting, fluid will leak under the hood, which will eventually lead to corrosion of metal parts. After replacement, be sure to:

1. Turn on the washer for 5-10 seconds and check for leaks.
2. Make sure that the jet hits exactly the center of the glass.
3. Check the fluid level in the reservoir - if it drops sharply, there is a leak somewhere.

Frequently asked questions about washer nozzles on Nissan Almera Classic

Can I install injectors from another Nissan model?

Yes, but with reservations. For example, injectors from Nissan Note (28550-4M025) fit the mounts, but have a different spray angle. Parts from Tiida or Micra, but hoses may need to be adjusted. It is better to choose analogues with the same nozzle diameter (0.8–1 mm).

Why does the fluid flow in a weak stream after replacing the injectors?

There are several reasons:

1. The filter in the tank or hoses are clogged.
2. The washer pump is faulty (check its voltage with a multimeter - it should be 12 V when turned on).
3. New injectors have a smaller nozzle diameter (found in cheap analogues).

First check the pump: it is located on the washer reservoir and should make a humming sound when turned on.

How to protect injectors from freezing in winter?

On Almera Classic The washer system is not heated, therefore:

• Use a winter washer with a freezing temperature no higher than -25°C.
• Before frost, add 100–200 ml of alcohol or special anti-gel to the tank.
• After washing the car, blow out the nozzles with compressed air (for example, a tire compressor).

If the liquid is still frozen, do not turn on the washer - this may damage the pump. Warm up the car in a warm garage or pour hot water over the injectors (not boiling water!).

What to do if after replacing the injectors there is a smell of antifreeze?

This is a wake-up call! On Almera Classic The washer reservoir is located next to the coolant expansion tank. Possible reasons:

1. A crack in the washer reservoir through which antifreeze enters the system.
2. Cooling system pipe leaking to the washer reservoir.

Immediately flush the washer system with water and repair the leak. Antifreeze in the washer corrodes hoses and paint!

Is it possible to paint the injectors so that they do not stand out?

Yes, but only with special paint for plastic (for example, Motip Plastik Lack). Before painting:

1. Remove the injectors and clean them of dirt.
2. Sand the surface with sandpaper (400-600 grit) for better adhesion.
3. Apply 2-3 thin coats of paint, drying for 10-15 minutes in between.

Don't use regular enamel - it will crack after a few months.
