Self-removal of the washer reservoir on a Nissan X-Trail T31: instructions with photos and tips

Removing the washer fluid reservoir Nissan X-Trail T31 (2007–2013) is a challenge that every owner faces sooner or later. The reasons may be different: from the banal replacement of a cracked reservoir to the modernization of the washer system or repair of neighboring components. Unlike many European crossovers, where the tank is located in an easily accessible place, T31 it is hidden quite deeply, which requires accuracy and knowledge of the nuances.

In this article we will analyze the dismantling process step by step, pointing out Hidden fastenings that are often overlooked, and we’ll share life hacks on how to do it without removing the bumper or front fender. You will also learn which tools are really necessary and which you can do without. If you have never worked with plastic clips or are afraid of damaging the pipes, don’t worry: there are solutions for beginners and experienced car owners.

Preparing for work: tools and materials

Before you begin dismantling, make sure you have everything you need. The absence of even one tool can delay the process for hours. Here is the minimum set:

• 🔧 Flat head screwdriver (preferably with a magnetic tip for ease of working with clips).
• 🔨 10 mm socket wrench (to unscrew the bolt securing the tank).
• 🧲 Magnet on telescopic handle (will help you get fallen nuts or clips from hard-to-reach places).
• 🧴 Silicone grease or WD-40 (for processing rubber pipes before removal).
• 📦 Plastic container (to fold small parts and not lose them).

If you plan to replace the tank with a new one, buy the original part with the article number in advance 28511-JM00A (for Nissan X-Trail T31 with engines QR25DE And MR20DE). Alternative analogues (for example, from Denso or Febi) may differ in the shape of the fasteners, so check compatibility. Also prepare new clamps for pipes - old ones often break when removed.

⚠️ Attention: Do not use metal tools to pry off plastic clips! Even a small force can break the bumper or fender liner. Better buy a special one plastic clip remover (costs about 200–300 rubles).

If you work in a garage, provide good lighting - the engine compartment X-Trail T31 It's dark, and without a flashlight it's easy to miss small details. We also recommend wearing rubber coated gloves: They will protect your hands from sharp plastic edges and prevent tools from slipping.

Where is the washer reservoir located on the Nissan X-Trail T31?

Unlike many cars, where the reservoir is located directly under the hood near the windshield, in X-Trail T31 it is hidden deeper - in right front fender (in the direction of travel). Exact location:

• 📍 To the right of the battery, closer to the headlight.
• 🔍 Under plastic protection (it needs to be removed).
• 🚗 Partially blocked by bumper, so full access is only possible when it is dismantled (but we will tell you how to do without this).

The tank is a white plastic tank with a volume of 4.5 liters with two necks: one for filling liquid, the second for connecting the pipe to the pump. On its body there is also level indicator (transparent flask with a float), which often breaks if removed carelessly.

System element	Location	Features of dismantling
Washer reservoir	Right front fender, protected	Attaches with 1 bolt and 2 plastic clips
Washer pump	Bottom of tank	Connected via a connector and a rubber pipe
Pipes	From reservoir to injectors and pump	Fixed with clamps, may stick
Level sensor	Top of the tank	Fragile, often breaks when removed

If you have never seen a tank in person, look at its diagram in electronic spare parts catalog (For example, Nissan EPC). This will help you figure out which parts need to be disconnected first. It is also useful to study photos of the disassembled engine compartment — there are a lot of them on specialized forums (for example, Drive2 or X-Trail Club).

Step-by-step instructions: how to remove the reservoir without removing the bumper

Many experts advise removing the bumper for convenience, but this takes a lot of time. We will tell you how to do without this while maintaining access to all fasteners. Follow the instructions:

1. Disconnect the battery. Remove the negative terminal to avoid short circuits when working with the pump's electrical connectors.

2. Drain the fluid from the reservoir. Use a syringe or bulb to suck out as much liquid as possible through the neck. The residue can be drained by disconnecting the lower pipe (place a container!).

3. Remove the plastic protection. It is secured with 3 clips and 1 bolt (10 mm socket wrench). Carefully pry off the clips using a flathead screwdriver, starting from the top.

   How to release clips without a puller?

   If you don’t have a puller at hand, use two flat screwdrivers: insert one under the clip as a lever, and lift the center with the other. The main thing is not to press too hard so as not to break the plastic.

4. Disconnect the pipes. Loosen the clamps and remove the hoses from the tank. If they are stuck, treat the connections WD-40 and wait 5-10 minutes.

5. Disconnect the pump connector. Press the latch and pull out the block. Be careful - the contacts are fragile!

6. Unscrew the fastening bolt. It is located at the bottom of the reservoir (10 mm socket wrench). After this, the tank can be carefully pulled up, tilting it slightly to the right.

If the reservoir does not come out from behind the bumper, try slightly bending the plastic fender protection (it is flexible). Do not use excessive force - the plastic may crack. In extreme cases, you will have to remove 2 bumper mounting bolts (right) and bend it back 5–7 cm.

⚠️ Attention: On some versions X-Trail T31 (for example, with an engine M9R - diesel) the tank can be mounted on an additional metal bracket. It needs to be unscrewed with an 8 mm socket wrench.

Common mistakes and how to avoid them

Even experienced car owners sometimes make mistakes when removing the washer reservoir. Here are the most common ones and how to prevent them:

• 🔧 Broken clips. Never pull the plastic protection by force - first unsnap all the clips. If one is broken, replace it with a new one (part number 08915-JA00A).
• 💧 Spilled liquid. Do not forget to substitute the container when disconnecting the pipes. Washer fluid may damage the paintwork!
• ⚡ Short circuit. Always disconnect the battery before working on electrical connectors. Even low voltage circuits can cause a failure in the control unit.
• 🔩 Lost bolts. Use a magnetic fastener holder. The tank mounting bolt easily falls into the subframe.

Another common problem is pipe damage when disconnected. If the hoses have hardened over time, do not try to pull them off by force. It’s better to cut them with a knife and then replace them with new ones (item number 28518-JM00A for the kit). Also check the condition clamps - if they are rusty, replace them with stainless steel worm ones.

If after installing a new reservoir the pump does not pump fluid, check:

• The connector is connected correctly (the contacts should click).
• Fuse integrity F30 (10A) in the block under the steering wheel.
• Lack of air in the pipes (when starting for the first time, press the pump several times to bleed the air).

How to check the tank and pump for functionality

Before installing the tank back, make sure it is in good working order. Here's how to do it:

1. External inspection. Check the housing for cracks, especially in the places where the pipes are attached. Microcracks can cause leakage.

2. Pump test. Connect the pump to the battery (plus to the terminal, minus to the body) - it should hum. If not, replace the pump (part no. 28500-JM00A).

3. Checking the level sensor. Blow into the pipe leading to the sensor - if the float moves, the sensor is working. A stuck float is a common cause of false readings on the dashboard.

If you are upgrading the system (for example, installing a larger tank), keep in mind that:

• 🔋 The pump must be compatible in terms of performance (the original is designed for 4.5 l).
• 📏 The new tank must not touch moving parts (for example, timing belt).
• 🔌 Electrical diagram remains the same - no need to change wiring.

To check the tightness after installation, pour water into the tank and leave for 10–15 minutes. If there are no leaks, you can add washer fluid. Do not use regular water in winter - it will freeze and burst the tank!

Tips for maintaining the washer system

To make the tank and pump last longer, follow these simple recommendations:

• 🌡️ Use quality liquid. Cheap washers contain aggressive additives that corrode plastic and rubber. Optimal choice - Liqui Moly Scheiben-Frostschutz or Hi-Gear.
• 🔄 Change the fluid seasonally. In summer, use a concentrate with anti-scale agent, in winter - with a freezing temperature no higher -25°C.
• 🧼 Flush the system. Once a year, fill the tank with clean water with added 10% vinegar (for 10 minutes), then rinse with distilled water.
• 🛠️ Check the injectors. If the stream is weak, clean them with a needle or compressed air. Clogged injectors increase the load on the pump.

If you often drive on dusty roads, install additional filter to the pipe going from the tank to the pump. This will prevent dirt from entering the system. You can make the filter yourself from a piece of foam rubber or buy a ready-made one (for example, Bosch 1 987 499 035).

⚠️ Attention: Do not mix washer fluids from different manufacturers! This can cause a chemical reaction that creates sediment that clogs the pipes and injectors.

Frequently asked questions about the Nissan X-Trail T31 washer reservoir

Is it possible to replace the reservoir without draining the fluid?

Technically possible, but extremely inconvenient. The liquid will spill out when the tank is tilted, dirtying the engine compartment. It is better to spend 5 minutes draining than to wash the engine later.

What is the volume of the washer reservoir on the X-Trail T31?

Standard volume - 4.5 liters. On restyled versions (2010–2013) it may be 5.0 liters due to the changed form.

Why does the pump work but no liquid flows?

There are several reasons:

• The filter or pipes are clogged.
• There is an air lock in the system (the pump needs to be bleed).
• Broken injectors (check them separately).

Can I install a tank from another Nissan?

Yes, but only from models on the platform Nissan C: Qashqai J10, Rogue (first generation). Tanks from Teana or Murano will not fit due to other fastenings.

How often should the tank be changed?

During normal use, the reservoir serves 10–15 years. Replacement is required only in case of mechanical damage (cracks, punctures) or if the plastic has become brittle from age.
