<em>Nissan Micra</em> washer reservoir: everything the owner needs to know

Washer reservoir in Nissan Micra - a seemingly simple part, but its malfunction can cause a lot of trouble. From cracked plastic to clogged nozzles, problems with your windshield washer system are more common than you think. This is especially true for models K12 (2002–2010) And K13 (2010–2017), where the design of the tank has its own nuances.

In this article we will look at how choose the right tank by article, which symptoms indicate its malfunction, and is it possible repair part instead of buying a new one. You will also learn how to avoid common mistakes when replacing and which fluids are best to use for the longevity of the system. If you are faced with the fact that the washer has stopped working or the reservoir is leaking, here you will find step-by-step instructions and useful tips.

Article numbers and compatibility: which tank is suitable for Nissan Micra

The first thing to start with is to determine exact article number washer reservoir for your model. U Micra They differ from generation to generation, and an error in selection can lead to problems with the installation or operation of the system.

For Nissan Micra K12 (2002–2010) the original tank has the article number 28511-4M000 or 28511-4M00A. These parts are interchangeable and suitable for most modifications, including versions with gasoline engines 1.2 And 1.4. For K13 (2010–2017) current articles 28511-JM00A or 28511-JM00B, depending on the year of manufacture and configuration.

• 🔧 Original vs analogue: Original tanks from Nissan are more expensive (from 3,500 to 5,000 rubles), but they guarantee a perfect fit. Among analogues, brands have proven themselves well Febi (article 28511), Hella And VAICO (price from 1,800 to 2,500 rubles).
• 🔄 Interchangeability: Tanks from Renault Clio II (article 7701207567) and Suzuki Swift (article 86511-60J00) may fit after minor modifications to the fastenings.
• ⚠️ Be careful with fakes! There are cheap copies on the market (from 800 rubles) with thin plastic that cracks after 1–2 years. Check for the presence of the manufacturer's logo and casting quality.

Please check before purchasing tank volume - in Micra K12 he makes up 3.5 liters, and in K13 — 4.2 liters. This is important if you plan to use non-standard fluids or upgrade the system (for example, adding a headlight washer).

Signs of trouble: when the tank requires replacement or repair

Window washer system in Nissan Micra It can fail for various reasons, but most often the tank is to blame. Here are the key ones symptoms, which are worth paying attention to:

• 💧 Liquid leak: Puddles under the car on the side of the front bumper (usually on the left side) or wet spots on the engine protection.
• 🚿 The washer does not work: The pump hums, but the liquid does not flow onto the glass (the mesh may be clogged or the tank may be cracked).
• 🔊 Extraneous sounds: Bubbling or whistling when the pump is running is a sign of air leaking through a crack.
• 🔥 Antifreeze smell: If antifreeze accidentally gets into the tank (for example, when the lids are mixed up), the plastic may corrode.

The most common problem is cracks in plastic, which appear due to:

• ❄️ Liquid freezing in winter (if not used anti-freeze).
• ☀️ Overheating of the tank (for example, when parking in direct sunlight).
• 🔧 Mechanical damage (impacts during repairs or accidents).

Before changing the tank, check integrity of hoses And pump operation. Sometimes the problem lies in oxidized contacts or a clogged filter. For diagnostics:

1. Remove the reservoir cap and visually inspect it for cracks.
2. Check the fluid level - if it drops quickly, there is likely a leak.
3. Disconnect the hose from the pump and blow it out - if air does not flow through, the filter or nozzles are clogged.

Step-by-step instructions: how to replace the washer reservoir with Nissan Micra

Replacing the tank is a procedure that you can do yourself in 30–60 minutes. You will need:

• 🔧 A set of keys (heads on 10 And 12).
• 🔨 Flat screwdriver for removing clamps.
• 🧴 New washer fluid (we recommend Liqui Moly Scheiben-Frostschutz).
• 🧽 Rags and container for draining old liquid.

Sequence of actions:

1. Drain the liquid. Unscrew the reservoir cap and use a syringe or tube to remove any remaining liquid. If the tank is cracked, place a container under the leak.
2. Remove the bumper (partially). To access the tank in Micra K12/K13 just unscrew it 2 bolts fastening the bumper from below and bend its left side. Some modifications may require removal of the engine protection.
3. Disconnect hoses and connectors. First, remove the fluid supply hose to the pump (it is secured with a clamp), then disconnect the electrical connector from the pump. Be careful - contacts may be fragile!
4. Remove the old tank. Unscrew 3 bolts fastening the tank to the body (usually under the head on 10). Carefully remove the tank without damaging the adjacent pipes.
5. Install a new tank. Do all the steps in reverse order. Before installation, check that the pump O-ring is intact.
6. Add fluid and check the system. Fill the tank at 2/3 and turn on the washer. Make sure that the liquid flows onto the glass without delay.

If the washer does not work after replacement:

• Check fuse (in the block under the steering wheel, usually F10 on 10A).
• Make sure pump receives power (test the contacts with a multimeter).
• Inspect injectors - they may be clogged or damaged.

What to do if the pump does not pump liquid?

If the pump hums but no fluid flows, the problem may be:

1. The filter at the pump inlet is clogged (needs to be washed or replaced).

2. Damage to the pump impeller (replacement of the pump is required, article number for K12 - 28531-4M000).

3. Break in the power supply (check the wires from the fuse box to the pump).

Repairing the washer reservoir: when is it possible and how to do it right

A crack in the tank does not always need to be treated by replacing it - sometimes it can be repair. However, this is a temporary solution and the problem will return within 6-12 months. Let's consider 3 repair methodsthat actually work:

1. Epoxy glue or cold welding.

   Suitable for cracks up to 3–5 cm. Procedure:

   • Clean and degrease the surface (use acetone or white spirit).
   • Apply glue (eg Loctite Epoxy Metal/Plastic) on both sides of the crack.
   • Secure with tape and leave on 24 hours.

⚠️ Attention: Do not use superglue (such as moment) - it does not hold the load and corrodes the plastic.

Soldering plastic.

To do this you need a soldering iron with a power 40–60 W and solder for plastic (for example, PLASTIX). The method is suitable for large cracks, but requires skills.

Installing a fiberglass patch.

Apply fiberglass cloth to the epoxy resin over the crack. This method increases strength, but worsens aesthetics.

If the crack is located at the bottom of the tank or near the fasteners, repair is useless - the part needs to be replaced. Also, you should not repair tanks with:

• 🔥 Traces of melting (for example, from contact with the outlet).
• 🧊 Multiple microcracks (“cobwebs”).
• 🚫 Destroyed threaded bushings for fastening.

Service life of a repaired tank:

Repair method	Service life (approx.)	Cost (RUB)
Epoxy glue	3–6 months	200–500
Cold welding	6–12 months	300–800
Soldering plastic	1–2 years	500–1,500 (with tool)
Fiberglass patch	1 year	600–1 200

Choosing washer fluid: what to put in Nissan Micra

Not only the cleanliness of the glass depends on the quality of the washer fluid, but also reservoir and pump life. B Micra The manufacturer recommends using liquids with a neutral pH (from 6.5 to 8.5) to avoid corrosion and destruction of the plastic.

Types of liquids and their features:

• 🌡️ Summer (concentrate or ready-made). Suitable for temperatures above +5°C. Top Brands: Liqui Moly Scheiben-Reiniger, Sonax Clear View.
• ❄️ Winter (anti-freeze). Must withstand temperatures up to -25°C (optimal for Russia -30°C). Avoid cheap compounds with methanol - they corrode rubber seals.
• 🔄 Universal (all-season). Convenient, but often contains aggressive surfactants. Example: Mannol Scheiben Reiniger.

What not to put in the tank Nissan Micra:

• 🚫 Tap water. Leads to plaque formation and corrosion of the pump.
• 🚫 Household detergents (Fairy, Myth). Foams and clogs the injectors.
• 🚫 Antifreeze or antifreeze. Destroys plastic and rubber hoses.
• 🚫 Undiluted concentrate. May crystallize at low temperatures.

For Micra K13 with headlight washer system use special liquids without dyes (eg Motul Tech Wash), so as not to clog the thin channels of the injectors.

💡

If the washer fluid begins to foam, flush the system with distilled water. To do this, disconnect the hose from the pump and run 1–2 liters of water through it.

Common mistakes when servicing the washer system

Even experienced owners Nissan Micra Sometimes they make mistakes that lead to breakdowns. Here TOP-5 misses and how to avoid them:

1. Ignoring leaks.

   If puddles appear under the car, but the washer is still working, many people postpone repairs. However, even a small leak leads to:

   • Pump overheating (running dry).
   • Corrosion of tank fastenings.
   • Dirt getting into the system.
2. Use of unsuitable liquids.

   In winter, many people pour the first anti-freeze they come across without checking the composition. Methanol liquids are cheaper, but they:

   • The rubber seals of the pump are corroded.
   • They evaporate faster, leaving a residue.
   • They have a pungent odor that penetrates the interior.
3. Incorrect installation of the tank.

   When replacing it is important:

   • Do not overtighten the fastening bolts (the plastic may burst).
   • Connect the hoses correctly (mixed pipes will lead to an air lock).
   • Check the pump O-ring (if it is torn, there will be air leaks).
4. They forget about the filter.

   In the tank Micra There is a fine mesh filter at the pump inlet. If you don't clean it, over time:

   • The fluid pressure decreases.
   • The pump overloads and burns out.
5. Independent modification of the system.

   Some owners install additional tanks or higher power pumps. This may lead to:

   • Overload of standard wiring (fuse F10 not designed for high current).
   • Hose rupture due to increased pressure.

⚠️ Attention: If after replacing the reservoir the washer operates jerkily, check air lock in the system. To remove it, disconnect the hose from the nozzle and let the pump pump the fluid manually (press the washer lever 3-4 times).

Upgrading your washer system: useful upgrades for Nissan Micra

Standard washer system Micra does not always cope with Russian realities (dirt, salt, frost). Let's consider 3 tested upgradesthat will improve its performance:

• 🔥 Tank heating.

  In winter, the liquid in the tank may freeze, even if an anti-freeze agent is used. Solution - installation heating element (for example, from Webasto or homemade based on a flexible cable). Cost: from 1,500 rubles.

  To connect, use a relay and fuse on 10Aso as not to load the standard wiring.

• 💦 Installation of an additional pump.

  If the standard pump is weak (especially important for Micra K12), you can connect a second pump in parallel (article no. 28531-JM000). This will increase the pressure and reduce the washing time.

  ⚠️ Attention: When making such an upgrade, check the capacity of the hoses - if they are too narrow, the pressure may rupture them.

• 🎯 Replacing nozzles with adjustable ones.

  Standard nozzles in Micra They often spray past the glass. The solution is to install adjustable nozzles (for example, from Bosch or HELLA). They allow you to adjust the direction and intensity of the jet.

  For installation you will need a drill 5 mm (if the fastenings do not match).

Cost and complexity of upgrades:

Upgrade	Cost (RUB)	Difficulty (1–5)	Installation time
Tank heating	1 500–3 000	3	2–3 hours
Additional pump	2 000–3 500	4	3–4 hours
Adjustable nozzles	800–1 500	2	1 hour

If you are planning a comprehensive upgrade, start with injectors - This is the simplest and most effective improvement. Heating the tank is relevant for regions with temperatures below -20°C, and the second pump will come in handy if you often drive off-road.

FAQ: answers to frequently asked questions about the washer reservoir Nissan Micra

🔧 Is it possible to drive without a washer reservoir cap?

Short term - yes, but permanently - no. Without a lid, dirt gets into the tank, which clogs the pump and injectors. In addition, the liquid evaporates faster, and in winter it can freeze due to snow.

❄️ What to do if the liquid in the tank is frozen?

Do not try to turn on the washer - this will burn the pump. Warm the tank with warm air (hair dryer, heater) or drive the car into a heated garage. After defrosting, drain the liquid and flush the system with water.

🔄 How often do you need to change the fluid in the tank?

It is recommended to update summer fluid every 2–3 months, winter - before the season (even if it remains from last year). If the fluid becomes cloudy or sediment appears, replace it immediately.

🚗 Is the tank suitable for Renault Clio on Nissan Micra K13?

Partially. Tank from Clio II (article 7701207567) is suitable for fastenings, but hoses may need to be replaced, since their length and diameter are different. Also check the compatibility of the pump connector.

💡 Is it possible to install a larger tank?

Theoretically yes, but in practice this is difficult due to the limited space under the hood Micra. The maximum volume that can be installed without modifications is 5 liters (for example, a tank from Nissan Note, article 28511-4M200).
