Nissan Almera G15 washer reservoir: Complete guide to replacement and repair

The windshield wiper system is a critical safety feature of any vehicle, and Nissan Almera G15 is no exception here. Precisely from serviceability washer reservoir depends on whether you can quickly clean the glass from dirt, insects or reagents in bad weather. In practice, owners of sedans of this generation are faced with a number of typical problems associated with the plastic tank.

The plastic from which it is made container for washer fluid, over time loses its properties under the influence of temperature changes and aggressive chemistry. This leads to cracks, loss of tightness and, as a result, to a constant flow of fluid under the hood. Ignoring such little things can lead to serious electrical problems or body corrosion.

In this article we will look in detail at what options exist. spare parts for your car, how to correctly diagnose a malfunction and how to replace the tank. We will also pay attention to the nuances of choosing pumps and nozzles, which are often changed along with the tank.

Design features and location of the tank on the Nissan Almera G15

On the model Nissan Almera generation G15 (production since 2012) the washer reservoir is located in the front part of the engine compartment, usually on the right or left, depending on the market and configuration. It is accessed after removing the plastic protective screens and, in some cases, the bumper, which somewhat complicates the DIY repair procedure.

The design of the reservoir provides for the presence of several compartments or a single container with partitions if the car is equipped with a headlight washer system. As standard, this is a single plastic tank, to which electric liquid supply pumps are attached. It is important to note that the filler neck often has an extended nipple that extends deep under the hood to avoid splashing when topping up.

Particular attention should be paid to fastenings. The tank is held on special brackets using rubber dampers, which become dull and break over time. This leads to the fact that when the engine vibrates, the tank begins to “walk”, which accelerates the process of crack formation in the places where hoses and pumps are attached.

Typical malfunctions and causes of their occurrence

The most common problem is the appearance of microcracks in the body of the tank. This is due to the fact that the plastic becomes brittle in the cold, and when trying to pump water out of the system or due to a mechanical shock (for example, when installing abnormal protection), the container bursts. Delamination of material is also often observed in places where seams are soldered or welded.

The second common malfunction is the failure of the electric pumps themselves or the breakage of electrical connectors. Water can get inside the connector, causing the contacts to oxidize, causing the washer pump will stop working even if the tank is intact. Sometimes the problem lies in clogged pump filters that stop passing liquid due to dirt or crystallization of reagents.

• 🌡️ Temperature changes: In winter, the frozen liquid inside expands and tears the plastic from the inside.
• 🦠 Chemical aggression: Cheap washer fluid concentrates can corrode seals and the plastic itself.
• 🔧 Mechanical damage: Incorrect installation of accessories or impacts from stones may damage the housing.

If you notice that the fluid level is dropping faster than usual and spots are forming under the car, you need to get it checked immediately. Often the leak is masked by smudges from other components, so it is important to accurately determine the source.

⚠️ Attention: If you find any fluid leaking, do not try to simply add water and continue operation. A leak can cause a short circuit in the wiring located near the reservoir, which could result in the entire wiring harness having to be replaced.

How to choose an original or a high-quality analogue

Replacement if necessary washer reservoir The owner is faced with the question: should he install an original part or turn to analogues? Original tank from Nissan is guaranteed to fit all geometric parameters and has high-quality plastic that is resistant to chemicals. However, its cost is often inflated, and it may not be available in dealer warehouses for months.

There are many analogues on the market, such as Sakura, Masuma or Sat. Their quality varies: some models are quite decent and last for years, while others burst after just one season. It is important to pay attention to the wall thickness and the quality of the casting - there should be no burrs on the surface, and the necks should have clear dimensions.

Be sure to check the part number before purchasing. For Nissan Almera G15 (1.6 and 1.5 diesel engines) part numbers may vary depending on the year of manufacture. Use the vehicle's VIN code for accurate identification, since tank designs for different engines may have differences in the location of the mounts and pipes.

Part type	Original article (example)	Popular analogues	Average price
Tank assembly	28930-1HC0A	Sakura, Masuma	4,500 - 7,000 rub.
Tank without pumps	28930-1HC0A (without us.)	Sat, Outlander	2,500 - 3,500 rub.
Washer pump	28931-31U0A	Febi, Vemo	1,200 - 2,000 rub.
Pump filter	28931-00U0A	Original	300 - 600 rub.

Step-by-step instructions for replacing the washer reservoir

The process of replacing the tank Nissan Almera G15 is not overly complicated, but it requires accuracy and free time. You will need to remove the front bumper to gain direct access to the container. This is necessary, since the tank mount is often hidden behind the plastic arch protection and subframe elements.

First you need to drain the remaining liquid. Disconnect the pump power connectors and unscrew the hoses. Be prepared for some of the liquid to spill onto the engine compartment, so place a rag or container. Next, unscrew the nuts securing the tank to the body and carefully remove it.

Installing a new element is done in the reverse order. Be sure to check the condition of the rubber seals and gaskets. If they have lost their elasticity, it is better to replace them immediately to avoid repeated leaks. When connecting the hoses, make sure they are tight and secured with clamps.

⚠️ Attention: Do not tighten the plastic hose clamps too much, otherwise you may damage the tank pipes, which will lead to a new leak. Use only standard fasteners or high-quality nylon ties.

What to do if the tank is cracked, but replacement is impossible?

If replacement is not possible immediately, you can temporarily seal the crack with epoxy resin or special plastic, after degreasing the surface. However, this is a temporary measure, since at subzero temperatures the repair may not withstand the pressure of the frozen liquid.

After installation, you need to check the operation of the system. Turn on the ignition and activate the washer. Make sure that the jets hit the desired areas of the glass and that the pumps operate without any extraneous noise. Check the tightness of all connections visually and by touch.

Repair and maintenance: how to extend the life of the tank

If the crack is small, sometimes it makes sense to try to restore the integrity of the tank rather than buy a new one. To do this, the method of soldering plastic or using special adhesives and sealants that are resistant to water and chemicals is used. However, this method is only suitable for cracks that do not pass through stiffeners.

Regular maintenance includes cleaning the pump filters. Dirt and sludge that settles at the bottom of the reservoir can get into the pump and cause it to jam. Remove the pumps, wash them and clean the strainers. It is also recommended to wash the tank itself with water and detergent once a year.

• 🧼 Use high-quality washer fluid: It should not leave sediment or crystallize.
• ❄️ Winter mode: In cold weather, be sure to use an anti-freeze with a freezing temperature lower than the current one outside.
• 🔍 Visual inspection: Periodically check the tank for abrasions and microcracks.

Don't forget that using water in the tank in the summer is normal, but in the winter it is guaranteed to cause the tank to burst. If you forgot to drain the water before frost and the tank bursts, repairs are inevitable. The most common cause of failure is frozen water inside the tank, which expands and tears the plastic from the inside.

Features of connecting injectors and pumps

After replacing the tank, it often becomes necessary to adjust the operation of the injectors. On Nissan Almera G15 nozzles with adjustable jet direction are used. Usually, a thin needle or sewing needle is enough to slightly bend the nozzle in the desired direction.

Electric pumps can also have different capacities. If you install an analogue one, make sure that its power matches the standard one. A pump that is too powerful can create excessive pressure, causing hoses to rupture or poor spray flow.

⚠️ Attention: When connecting the electrical connectors of pumps, be sure to observe the polarity, if it matters for a particular pump model, and check that the connector latches are firmly secured to avoid oxidation of the contacts.

If the system does not work after replacement, check the fuse. On Nissan Almera it is usually located in the fuse box in the engine compartment marked "WASHER" or "WIPER". In rare cases, the problem may be with the relay or wiring.

Conclusion and operating tips

Washer reservoir on Nissan Almera G15 is a consumable item that, if properly cared for, will last a long time. The main enemy of the system is water in winter and low-quality reagents. Timely replacement of a cracked tank and regular checking of leaks will help avoid costly electrical wiring repairs.

When choosing spare parts, do not chase the lowest price. Cheap analogues often have casting defects and cannot withstand loads. Original or proven brands are an investment in your safety and comfort while driving. Remember that clean glass is the key to road visibility in any weather.

If you doubt your abilities when replacing a tank, it is better to entrust this work to professionals. Improper installation can cause the bumper to not fit into place, gaps will appear, and water will flow into the arches, causing corrosion.

How can you tell if your washer reservoir is cracked?

The main signs are: a constant smell of washer fluid in the cabin, a drop in the fluid level for no apparent reason, leaks under the front bumper after using the washer, as well as visual cracks when inspecting the engine compartment.

Is it possible to use water in the tank in winter?
