<em>Nissan Teana J31</em>windshield washer nozzles: selection, replacement and repair

Nissan Teana J31 - a car that is valued for its reliability and comfort, but even small but important parts wear out over time. One of these is windshield washer nozzles. At first glance, this is a simple part, but when it fails, it turns into a real problem: dirt on the glass is not washed off, liquid flows past or does not flow at all. In this article we will look at how to correctly select, replace and repair injectors on Teana J31so as not to overpay for the service.

Many owners are faced with the fact that over time the jet of washer fluid becomes weak or sprays unevenly. Sometimes the problem lies in clogging, but most often the injectors are to blame - their mechanism wears out, and the O-rings lose their elasticity. We will tell you in detail how to diagnose a malfunction, select original spare parts or high-quality analogues, and also give step-by-step replacement instructions with nuances that are not written about in standard manuals.

Signs of malfunctioning washer nozzles on Nissan Teana J31

The first signal that something is wrong with the injectors is change in the nature of liquid spray. Instead of a smooth stream or fan, you can observe:

• 💧 Weak pressure — the liquid barely drips or splashes in a thin stream.
• 🌀 Uneven Spray — one nozzle works normally, but the second “spits” or hits to the side.
• 🚫 Complete absence of fluid — when you press the washer lever, nothing happens (the reservoir is full and the pump is running).
• 🔊 Extraneous sounds — hissing or whistling from under the hood when the washer is activated.

If you notice at least one of these symptoms, do not rush to change the injectors. First check:

1. Liquid level in the tank (sometimes the problem is trivial - they forgot to top it up).
2. Condition of hoses - they could bend or burst.
3. Pump operation — when the washer is turned on, a characteristic buzzing sound should be heard.

⚠️ Attention! If the pump does not turn on at all, the problem may be in the fuse. F30 (10A) or relay K11 in the mounting block. On Teana J31 they are responsible for the washer circuit.

If everything is fine with the pump and hoses, but the liquid is not sprayed properly, the injectors are to blame. You can try to clean them, but most often they need to be replaced.

Original injectors vs analogues: what to choose for Teana J31

On Nissan Teana J31 (2008–2013) washer nozzles with article number were installed 28522-JM00A (for heated models) and 28522-JM000 (without heating). Original parts from Nissan They are expensive - from 1,500 to 2,500 rubles apiece, but they are guaranteed to fit in the seats and will not cause problems with installation.

However, there are high-quality analogues on the market that are cheaper:

Brand	Article	Price (per piece), ₽	Features
Denso	550-0101	800–1 200	High atomization quality, long service life
Valeo	698359	900–1 300	Universal, suitable for many Japanese cars
Hella	8XF 355 341-001	1 000–1 400	Good frost resistance
Febi	28522	600–900	Budget option, but the spray quality is worse than the original

When choosing analogues, pay attention to:

• 🔧 Mounting type - on Teana J31 The injectors are secured with latches, so it is important that the seat matches.
• 🌡️ Presence of heating — if your car is equipped with this option, take heated injectors (usually they have an additional power connector).
• 💦 Spray type — original nozzles produce a fan-shaped jet, some analogues can spray in a jet, which cleans the glass worse.

⚠️ Attention! Cheap off-brand injectors (for example, from NoName) often have poor sealing. This leads to fluid leaks on the hood and paint corrosion.

On Teana J31 Since the 2011 release, the washer nozzles have a slightly modified design of the heating connector (article no. 28522-JM01A). Please check this point when purchasing, otherwise you will have to modify the wiring.

Step-by-step instructions for replacing washer nozzles

Replacing injectors with Nissan Teana J31 does not require special tools - just a flat screwdriver and 10-15 minutes of time. The main thing is to act carefully so as not to break the plastic latches.

New injectors (2 pcs.)

Flathead screwdriver or plastic puller

Rags

Washer fluid (to check)

Silicone grease (optional, for O-rings) -->

Step 1. Preparation

Open the hood and find the injectors - they are located on a plastic panel under the windshield, on either side of the center. Remove the washer reservoir cap (if it interferes) and disconnect the negative terminal from the battery to avoid a short circuit when working with heating.

Step 2. Removing the old injector

Using a flat-head screwdriver, carefully pry the nozzle from the side where the latch is located. Do not pull it up - first you need to unclip the latch and then remove the part. If the nozzle is heated, first disconnect the power connector.

Step 3: Installing a new injector

Before installation, check the O-ring on the new injector - it should be intact and elastic. Insert the nozzle into the seat until it clicks, then connect the hose and (if available) the heating connector. Repeat the procedure for the second injector.

Step 4. Checking the work

Pour washer fluid into the reservoir, connect the battery and check the operation of the washer. The jet should hit exactly the center of the glass. If the liquid is sprayed crookedly, adjust the direction of the nozzle with a needle (most models have an adjustment ball inside the nozzle).

What to do if the new injector leaks?

If after replacement fluid leaks from under the nozzle, the reason may be:

1. Damaged O-ring (replace it or use silicone sealant).

2. Loose fit (check whether the nozzle is fully latched).

3. Crack in the body (defective part, requires replacement under warranty).

Cleaning injectors without replacing: when possible

If the injectors are clogged but are mechanically intact, you can try cleaning them. This is relevant if:

• 🔍 The stream is weak, but the liquid still flows.
• 🌑 A coating of salts or dirt is visible on the nozzles.
• 💡 The injectors are relatively new (less than 2-3 years old).

Method 1. Washing without removal

Fill the washer reservoir with a mixture of:

• 50% distilled water,
• 50% vinegar or citric acid (to dissolve salts).

Activate the washer for 10-15 seconds, then leave the mixture in the system for 30 minutes. Afterwards, rinse with clean water.

Method 2. Cleaning with a needle or compressor

If flushing does not help, remove the injectors and:

1. Blow them out compressor (pressure no more than 2 atm).
2. Clean the nozzle fine needle (not metal, so as not to damage).
3. Rinse in ultrasonic bath (if possible).

⚠️ Attention! Do not use wire or hard brushes for cleaning - this will deform the nozzle and the jet will flow unevenly.

Typical replacement mistakes and how to avoid them

Even something as simple as replacing injectors can cause problems if mistakes are made. Here are the most common:

1. Damage to plastic latches

Many owners Teana J31 they break the clamps, trying to pull the nozzle out by force. Solution: Use a plastic puller or pry the latch from the side, not from the top.

2. Mixed up hoses

On some trim levels Teana J31 The hoses to the injectors are of different lengths. If they are mixed up, the jet will hit the wrong point on the glass. Solution: Before removing, take a photo of the connection or mark the hoses with a marker.

3. Ignoring O-rings

Old rings become tanned over time and do not provide a tight seal. Solution: Always replace the rings with the injectors or lubricate them with silicone grease before installation.

4. Incorrect adjustment

After replacement, the injectors often hit too high or low. Solution: adjust the direction of the jet with a needle (insert it into the nozzle and carefully turn the ball inside).

Heated injectors: features and diagnostics

On Nissan Teana J31 Heated injectors were installed in top trim levels. This option prevents the liquid from freezing in cold weather, but adds difficulties during diagnosis.

How to check heating:

1. Turn on the ignition.
2. Measure the voltage at the injector connector (should be 12V).
3. If there is no voltage, check the fuse F30 and relay K11.
4. If there is voltage, but the injector does not heat up, replace it (the heating element has burned out).

When replacing heated injectors, consider:

• 🔌 The power connector must fit tightly - no backlash!
• 🌡️ After installation, check the heating operation by connecting the tester in resistance test mode (there should be 10–20 Ohm).
• ❄️ In cold weather, do not use ordinary water in the washer - even with heating, the risk of freezing remains.

Is it possible to install heated injectors instead of regular ones?

Yes, but you will need:

1. Lay the wiring from the relay K11 to the injectors.

2. Install an additional fuse (10A).

3. Set up heating control (on some versions Teana J31 it is activated automatically at temperatures below +5°C).

FAQ: Frequently asked questions about washer nozzles Nissan Teana J31

Is it possible to drive without one working injector?

Technically possible, but not advisable. One nozzle will not be able to clean the entire glass evenly, especially in rain or headwinds. In addition, if the problem is a blockage, it can switch to the second nozzle.

Why does the liquid splash past the glass after replacing the injectors?

Most likely the injectors are not adjusted. Insert the needle into the nozzle and gently rotate the ball inside to direct the stream to the center of the glass. Also check that the hoses are not mixed up (on Teana J31 they sometimes have different lengths).

How often should washer nozzles be replaced?

The service life of original injectors is 5–7 years. Analogs last less (3–5 years). However, a lot depends on the quality of the washer fluid: if you use water instead of a special fluid, the nozzles will clog faster.

Is it possible to install injectors from another car?

Theoretically yes, but only if they match:

• Type of fastening (latches or threads),
• Hose diameter,
• Presence/absence of heating.

For example, injectors from Nissan X-Trail T31 (article 28522-4M00A) fit the seats, but may differ in spray angle.

What should I do if, after replacing the injectors, the pump does not pump fluid?

Check:

1. Connecting the hoses to the pump (they may have come off during replacement).
2. fuse operation F30 and relay K11.
3. Pump condition - it may have burned out due to overload (for example, if the hoses were pinched).
