Owners Nissan Note sooner or later you have to face the need to find the engine number - be it for registration with the traffic police, purchasing spare parts or checking the history of the car. But if everything is more or less clear with the VIN number (it is usually located on the windshield or in the door opening), then difficulties often arise with the power unit number. Where exactly to look for it? How to distinguish original markings from interrupted ones? And what to do if the number is erased or missing?

In this article we will look at all possible engine number locations on Nissan Note first (E11, 2004–2013) and second (E12, 2013–2020) generations, and also learn how to decipher it according to manufacturer standards. In addition, you will learn how to check the authenticity of the license plate and avoid problems when buying a used car. Material added unique photos and diagrams from real cars, which will help even a beginner to navigate.

Where is the engine number on a Nissan Note: all possible places

Manufacturer Nissan does not adhere to a single standard for all models, therefore Note The engine number may be located in several places. Main options:

  • 🔧 Cylinder block (on the right in the direction of travel) - the most common place. The number is stamped on a special area next to the oil filter or thermostat.
  • 🔍 Timing cover - on some modifications (for example, with an engine HR15DE) number is duplicated here.
  • 📏 Oil pan - rare, but found in early versions Note E11 (2004–2006).
  • 🔄 Body plate — the engine number can be indicated next to the VIN on the nameplate in the engine compartment.

On most Nissan Note with gasoline engines HR12DE, HR15DE And HR16DE The number is stamped on the cylinder block on the right side (if you look in the direction of travel of the car). To see it, you will need to remove the plastic engine cover and, possibly, clean the area from dirt. On diesel versions (for example, K9K) the number is usually located on the block closer to the gearbox.

⚠️ Attention: On vehicles manufactured after 2018, the engine number may be laser engraved instead of traditional embossing. Such inscriptions are more difficult to fake, but they are more difficult to see without good lighting.

If you cannot find the number on the block, inspect the timing cover - sometimes it is duplicated there in the format ENGINE NO: XXXXXX. On Note E12 (restyling 2016) the number may be hidden under the air duct - it will have to be temporarily dismantled.

📊 What engine is installed on your Nissan Note?
  • HR12DE (1.2)
  • HR15DE (1.5)
  • HR16DE (1.6)
  • K9K (diesel 1.5)
  • Other

What an engine number looks like: format and examples

Engine number Nissan Note consists of two parts:

  1. Prefix (engine model) - for example, HR15DE or K9K736. This part indicates the series and modification of the power unit.
  2. Serial number - a unique combination of 6–8 numbers and letters, for example, 123456 or A7B8C9D0.

Examples of full numbers:

  • 📌 HR15DE 234567 — gasoline engine 1.5 l (109 hp).
  • 📌 K9K736 89ABCD — 1.5 l diesel engine (90 or 110 hp).
  • 📌 HR16DE 1A2B3C — gasoline engine 1.6 l (117 hp).

Important: On some engines the prefix and serial number are separated by a space or dash, on others they are not. For example, it might be written HR15DE234567 without separator. This is not an error - both options are valid.

Engine model Volume Example number Years of installation on Note
HR12DE 1.2 l HR12DE 123456 2013–2020
HR15DE 1.5 l HR15DE A1B2C3 2004–2020
HR16DE 1.6 l HR16DE 789ABC 2010–2020
K9K 1.5 l (diesel) K9K736 4D5E6F 2006–2014

If on your Note engine number starts with letters CR (For example, CR14DE), this means that the engine was replaced with a non-original one (possibly with Nissan Micra or Juke). Such cases require additional verification.

💡

Use a flashlight or LED lamp to inspect the room - often the knockout area is in the shadows and is difficult to see.

How to decipher Nissan Note engine number

The number prefix (first 5–7 characters) contains information about the engine model and characteristics. Let's decipher it using an example HR15DE:

  • 🔤 HR — engine series (HR-family, developed Nissan in the 2000s).
  • 📏 15 — volume in deciliters (1.5 l).
  • 🔧 D — DOHC (double camshaft).
  • ⚡ E — electronic fuel injection (EFI).

For diesel engines K9K decoding is different:

  • 🔤 K9 - a series of diesel engines developed jointly with Renault.
  • 🔢 K - modification (for example, K9K736 - turbocharged version).

The serial number (after the prefix) does not carry technical information - it is a unique identifier of a specific engine. However, you can check the history on it through databases Nissan or services like CarVertical (if the number is not interrupted).

⚠️ Attention: If the number prefix does not match the PTS data (for example, the documents indicate HR15DE, and on the engine HR16DE), this may mean replacing the engine without registration. Such cases require clarification from the previous owner or the traffic police.
How to check the engine by number through the official Nissan service?

Official service Nissan does not provide public access to the database of engine numbers, but dealers can make a request by VIN. An alternative is services like EpicVIN or Carfax, where the repair history is sometimes displayed by unit number.

Step-by-step instructions: how to find and read the engine number

To find the engine number yourself Nissan Note, follow these instructions:

Open the hood and lock it

Remove the plastic engine cover (if equipped)

Clean the license plate area from dirt (use a brush and WD-40)

Prepare a flashlight and a mirror on the telescopic handle

-->

Step 1. Define the search side:

  • On HR12DE/HR15DE/HR16DE the number is right (in the direction of travel) on the cylinder block, next to the oil filter.
  • On K9K (diesel) - on the block closer to the gearbox (can be hidden under the air duct).

Step 2. Inspect the site:

  • The number can be stamped on the metal or lasered.
  • On older engines (Note E11 until 2010) the knockout is rougher, on new ones (E12) - be more careful.

Step 3. Take a photo of the number:

  • Take several pictures from different angles - this will help when checking.
  • If the number is erased, try wiping the pad with solvent (sometimes dirt masks the numbers).

Step 4. Check with documents:

  • The number on the title must match the one on the engine (except in cases of official replacement).
  • If there are discrepancies, request a history from the previous owner.

If the number is missing or difficult to read, contact the service center Nissan - they can help with identification by VIN or other parameters.

💡

On engines Nissan Note after 2016, the number is often duplicated on a metal plate under the hood (next to the VIN).

What to do if the engine number is erased or missing

Situations where the engine number is unreadable or missing are not so rare. The reasons may be different:

  • 🔨 Corrosion or mechanical damage - especially relevant for cars older than 10 years.
  • 🔧 Replacing the engine without changing the number — a new unit could be installed without registration.
  • 🚨 Deliberate deletion - for example, in case of theft or document fraud.

If the number is erased, try the following steps:

  1. Cleaning the site. Use fine sandpaper (1000-1500 grit) and WD-40. Rub the surface gently—sometimes the numbers will show through.
  2. UV lamp. Some laser engraved numbers become visible under ultraviolet light.
  3. Acid developer. Car service centers use special reagents to restore erased license plates (for example, Metal Etch).
  4. Contacting the traffic police. If the number is not restored, an examination will be required to confirm the originality of the engine.
⚠️ Attention: If you buy Nissan Note with an unreadable engine number, demand a price reduction or refuse the deal. Restoring the number through an examination will cost 5–15 thousand rubles, and there are no guarantees of success.

In cases where the engine is replaced, but the number is not changed, the owner will have to legalize the replacement through the traffic police. For this you will need:

  • Car purchase and sale agreement.
  • Receipt for the purchase of the engine (if saved).
  • Diagnostic report from the service center.

How to check the originality of the engine number

Forging engine numbers is a common practice when selling used cars. To avoid being scammed, pay attention to the following signs:

  • 🔍 Uneven embossed edges. The original numbers have clear contours, while the broken ones have jagged or double lines.
  • 🎨 Traces of paint or putty. Fraudsters often cover up the old number and apply a new one.
  • 📏 Font mismatch. On Nissan All characters must be the same size and style.
  • 🔢 Illogical sequence. For example, number HR15DE 000001 on a 2015 model car is suspicious.

To authenticate, follow these steps:

  1. Compare with VIN. The last 6 characters of the VIN and the engine number must not match - these are different identifiers.
  2. Check through the services. Request a VIN report from CarVertical or Autocheck — the engine history may be indicated there.
  3. Inspect the engine mounts. If the bolts on the cushions show signs of recent dismantling, the unit may have been replaced.

If you doubt the authenticity of the number, order forensic examination. The cost is from 3 thousand rubles, but this will eliminate the risks of buying a stolen or damaged car.

💡

Upon examination Nissan Note Pay attention to the condition of the engine mounting bolts. If they look new or have scratches from the key, this may indicate a recent replacement.

Common mistakes when searching and reading engine numbers

Even experienced car owners sometimes make mistakes when working with the engine number. Here are the most common:

  • 🔧 They confuse the engine number with the body number. VIN and engine number are two different things! VIN is longer (17 characters) and starts with letters JN1 (for Nissan).
  • 📸 Photograph the number at an oblique angle. Because of this, the numbers may not be read correctly (for example, 6 instead of 8).
  • 🧹 Use aggressive cleaners. Solvents like acetone can completely erase any traces of the license plate.
  • 🔍 Duplicates are not checked. On some Note The number is duplicated on the plate under the hood - this will help clarify the data.

Another common mistake is ignoring technical passport. The PTS or STS must indicate the engine number (column “Engine No.”). If it does not match what is on the unit, this is a reason to be wary. The exception is an official engine replacement, confirmed by documents.

Upon purchase Nissan Note Always check the engine number with the data in the vehicle title and inspect the unit for signs of repair. If the seller refuses to allow access to the engine for inspection, that's a red flag.

⚠️ Attention: On some Nissan Note after 2018, the engine number can be indicated electronically - in the control unit (ECU). It can only be read through a diagnostic scanner (for example, Launch X431).
