Under the hood Nissan Note even experienced car owners sometimes get lost: the compact dimensions of the car dictate a non-standard arrangement of key components. There are no usual “classics” here like battery under the windshield or oil filler neck in the center — engineers Nissan optimized the space for the specific tasks of an urban hatchback. If this is your first time opening the hood Note E11 or E12, then this article will help you figure out where everything is.
We will analyze in detail arrangement of main elements - from the fuse box to the expansion tank, we'll explain why some parts aren't hidden where you expect, and give practical maintenance tips. We will pay special attention unique feature Nissan Note: battery shifted to the right, which often causes confusion when “lighting up”. You will also find current diagrams for gasoline (HR12DE, HR16DE) and diesel (K9K) versions.
Engine compartment diagram Nissan Note: what is where
Let's start with a visual guide. Below is a basic diagram for most modifications Note (years 2006–2020). Please note: Layout may vary slightly depending on year and engine type, but key elements remain in place.
| element | Location | Notes |
|---|---|---|
| Battery | On the right (in the direction of travel), under the plastic cover | The terminals are covered with protective caps, negative is on the right |
| Oil filler neck | Left, on the valve group cover | Yellow pen with inscription OIL |
| Fuse box | At the left glass of the counter, under the black lid | Duplicate unit - in the cabin under the steering wheel |
| Coolant expansion tank | On the right, next to the battery | Transparent plastic with marks MIN/MAX |
| Washer reservoir | Left, near the front bumper | White plastic with blue cap |
For clarity, here is a photographic comparison of the engine compartment Note E11 (2006–2013) and E12 (2013–2020). On E12 additional sound insulation for the hood appeared, and the fuse box was moved closer to the windshield. If your machine is equipped turbocharged engine HR12DDR, then on the left under the hood you will see an intercooler - it is often confused with the air conditioning radiator.

Battery: where to look and how to remove it correctly
The most common question from owners Nissan Note: "Where's the battery?". Unlike most cars, where the battery is located on the left, here it is hidden on the right under the plastic cover with the inscription BATTERY. This decision is related to the layout of the body and the need to distribute weight for better handling.
To get to the battery:
- 🔧 Open the hood and find the black plastic cover on the right.
- 🔧 Press the latch on the front of the cover and pull it up.
- 🔧 Under the cover you will see terminals (minus on the right, plus on the left), covered with protective caps.
- 🔧 To remove the battery, first disconnect the negative terminal, then the positive one.
An important nuance: in Nissan Note smaller batterythan in most B-class cars. Standard size - DIN 43Ah (length 207 mm, width 175 mm, height 190 mm). It is not recommended to install a battery with a larger capacity: it may not fit into the allotted space or damage the mounts.
If, when lighting up another car, the wires do not reach the battery Note, use extension cables or temporarily remove the battery and move it closer to the donor.
⚠️ Attention: When the battery is disconnected Nissan Note The audio system protection is triggered. After connecting the battery, you will need to enter the radio unlock code (indicated in the service book or on a sticker in the glove compartment).
Fuse box: location and decoding
B Nissan Note two fuse blocks: main one under the hood And additional in the cabin. The engine compartment block is located at the left glass of the counter, under a black plastic cover with the inscription FUSES. To open it, press the latch at the top.
Inside you will find:
- 🔌 Fuses (indicated by letters
Fand numbers). - 🔌 Relays (indicated by letters
R). - 🔌 Diagnostic connector for scanner (on some versions).
Below is a breakdown of the key fuses for Note E12 (2013–2020) with engine HR16DE:
| Number | Ampere | Purpose |
|---|---|---|
| F1 | 10A | Engine Management System (ECM) |
| F5 | 15A | Anti-lock braking system (ABS) |
| F10 | 10A | Cigarette lighter |
| F14 | 20A | Heater fan |
| F20 | 15A | Audio system |
If the fuse is blown, replace it with one of the same rating. Using bugs or larger amperage fuses may result in fire in the engine compartment. To check the fuses, use a multimeter or visually inspect the filament.
☑️ Checking fuses in Nissan Note
Cooling system: tanks, pipes and nuances
B Nissan Note used closed cooling system with an expansion tank, which is located on the right next to the battery. The tank is made of translucent plastic with marks MIN And MAX. The coolant level should be between these marks on a cold engine.
Key elements of the cooling system:
- 🔥 Radiator: located at the front, behind the bumper. Access to it is blocked by the air conditioner condenser.
- 🔥 Pump: driven by the timing belt (on
HR16DE) or a separate belt (onK9K). - 🔥 Thermostat: located in the housing at the engine outlet (on the left, when viewed in the direction of travel).
- 🔥 Radiator fan: turns on automatically when the coolant temperature reaches ~95°C.
Feature Nissan Note: narrow cooling system pipes, which can crack over time due to vibrations. When replacing coolant, use original fluid. Nissan Coolant L250 (blue) or analogues (Coolstream NRC, Sintec Unlimited). Mixing liquids of different colors is prohibited!
⚠️ Attention: On diesel versions (K9K) installed in the cooling system additional heat exchanger for interior heating. When flushing the system, it must be cleaned separately, otherwise the stove will blow cold air.
How to check the operation of the thermostat without removing it?
Start the cold engine and touch the lower radiator hose. It should remain cold until the coolant temperature reaches ~85°C. If the pipe heats up immediately, the thermostat is stuck in the open position.
Oil filler neck and dipstick: how not to confuse them
Oil filler neck in Nissan Note is located on the left on the valve group cover and is indicated by a yellow pen with the inscription OIL. The neck diameter is standard - any funnel for motor oil is suitable. Located nearby oil level dipstick (orange ring).
Important points:
- 🛢️ Check the oil level on a warm engine (5 minutes after stopping).
- 🛢️ The optimal level is between the marks
MINAndMAXon the dipstick. - 🛢️ For engines
HR12DEAndHR16DEoil recommended5W-30or0W-20(specificationAPI SN/ILSAC GF-5). - 🛢️ Oil volume when changing:
3.2 lforHR12DE,4.3 lforHR16DE.
A common mistake owners make: confusion between oil filler neck and power steering fluid neck (if there is one). On Note with electric power steering (EPS) there is no power steering reservoir - a maintenance-free system is used instead. If your car is equipped with power steering, the reservoir is located on the right side below the battery (white plastic with a black cap).
On engines HR16DE after 2016 the system was installed automatic oil level control. If the oil drain icon lights up on the dashboard, check the level with a dipstick - the sensor may give false alarms.
Maintenance and typical engine compartment problems
Engine compartment Nissan Note requires regular attention, especially if the car is operated in city mode with frequent traffic jams. Here are the key maintenance points:
1. Cleaning the drainage holes
In the front part of the engine compartment (near the windshield) there are drainage holes for draining water. Over time, they become clogged with leaves and dirt, which leads to accumulation of water under the hood and corrosion of metal parts. Clean the holes at least twice a year.
2. Checking the tightness of the pipes
Due to the tightness under the hood, the cooling and crankcase ventilation pipes often rub against other parts. Inspect them for cracks or abrasions at every maintenance. Particularly vulnerable pipe from expansion tank to radiator — it is made of soft plastic.
3. Checking the condition of belts
- 🔄 On
HR16DEThe timing belt requires replacement every120,000 kmor 5 years. - 🔄 Check the alternator belt for cracks and wear every
60,000 km. - 🔄 On diesel
K9KThe timing belt is changed every100,000 km, but his condition needs to be monitored more often due to high loads.
4. Electrical problems
Due to the close location of the battery and fuse box to the windshield, in rainy weather there may be short circuits. If after heavy rain the car does not start or the fuses trip, dry the unit with hair dryers or contact a service center to check the tightness of the seals.
Modernization of the engine compartment: what can be improved
Owners Nissan Note often complain about insufficient hood sound insulation And poor ventilation of the engine compartment. Here are a few proven improvements:
1. Additional sound insulation
Install sheets on the inside of the hood Splen 4mm or Bitoplast 10mm. This will reduce rain noise and engine vibration. The main thing is not to block the ventilation holes.
2. Enhanced ventilation
A popular modification on owner forums is the installation of additional radiator deflectors to improve airflow. This is true for cars with air conditioning, where the standard fan does not always cope with the load.
3. Electrical protection
To prevent corrosion of the fuse box contacts, treat them CRC contact lubricant or Liqui Moly Electronic-Spray. You can also install additional cover made of plastic or rubber to protect against moisture.
4. LED lighting of the engine compartment
Standard lighting under the hood in Note no. Can be installed LED strip 12V powered by cigarette lighter or battery. The main thing is to insulate the wires and secure the tape so that it does not interfere with maintenance.
When installing additional equipment (for example, an alarm or a DVR), avoid laying wires above the engine. High temperatures can damage the insulation. The optimal route is along the left wing.
FAQ: Frequently asked questions about the engine compartment Nissan Note
Where is the engine number on Nissan Note?
The engine number is stamped on cylinder block, on the left (in the direction of travel), next to the gearbox. For inspection, you will need to remove the plastic protection (if installed). On diesel K9K The number may be hidden under the turbine pipe.
What kind of antifreeze to pour into Nissan Note?
For all modifications Note Ethylene glycol based antifreeze that meets specifications is recommended Nissan Coolant L250 (blue). Suitable analogues: Coolstream NRC, Sintec Unlimited, Felix Carbox G12+. Mix with other types (eg. G11 or G13) it is impossible!
Why in Nissan Note Does the battery drain quickly?
Main reasons:
- 🔋 Small battery capacity (total 43Ah) - in cold weather it may not be enough to start.
- 🔋 Leakage current through an audio system or alarm system (norm - up to 50 mA).
- 🔋 Short trips — the generator does not have time to charge the battery.
Solution: check the leakage current with a multimeter, replace the battery with a model with a capacitance 50–55Ah (if space allows), or install mass cutter.
Is it possible to wash the engine compartment? Nissan Note Karcher?
You can wash it, but with caution:
- 🚿 Close fuse box, generator And air intake polyethylene.
- 🚿 Use wide spray nozzle (not a point jet!).
- 🚿 After washing, blow with compressed air battery contacts And candle wells.
Do not wash the engine in cold weather - water in the connectors may freeze and damage the contacts.
