Nissan Note engine number: where is it located, how to check and decipher it

Engine number Nissan Note is a unique identifier that is required for registration with the traffic police, checking the car’s history and selecting spare parts. However, finding it is not as easy as it seems: the manufacturer places markings in non-obvious places, and on different generations (E11 2006–2013 and E12 2013–2020) location may vary. In this article you will learn where exactly to look for the number on gasoline (HR16DE, HR12DE) and diesel (K9K) motors, how to read it correctly and what to do if the markings are erased or missing.

We will pay special attention to decoding VIN code and engine numbers - these data are closely related, and their discrepancy may indicate a replacement power unit or more serious problems (for example, number interruption after theft). We’ll also look at how to check the originality of the engine through traffic police databases and services like Autocode or CarVerticalwithout falling for scammers' tricks.

Where is the engine number on a Nissan Note?

On Nissan Note The engine number is stamped in two zones - it depends on the type of engine and year of manufacture. Main places:

• 🔧 On the cylinder block (on the right, when looking in the direction of travel) - a standard place for most HR16DE And HR12DE. Look for a flat area next to the oil filter.
• 🔍 On the front of the engine (closer to the radiator) - typical for diesel engines K9K and some earlier versions E11.
• 📌 On the plate under the hood — the number is duplicated (not always), but this is not the official marking for the traffic police.

To get to the room you will need:

1. Open the hood and secure it.
2. Remove the protective plastic casing (if any) - it is secured with latches.
3. Clean the area from dirt (use a brush and WD-40, but not metal tools - the marking may be damaged).
4. Light it with a flashlight - the number is often stamped in small print (approximately 5–7 mm).

On Nissan Note E12 (2013–2020) the number is most often located on the cylinder block closer to the gearbox. On E11 (2006–2013) may be hidden under the intake manifold - here you will have to remove the pipes. If you can't find the markings, check:

• 🔦 Left side of the engine (driver's side) - sometimes the number is duplicated.
• 📄 Certificate of Registration — the number is indicated there, but it may not coincide with the real one (if the motor has been changed).

What an engine number looks like: format and examples

Engine number Nissan Note consists of 14–17 characters (letters and numbers) and has a clear structure. Example for HR16DE:

HR16DE 1234567

Explanation:

• HR16DE — engine model (first 6-7 characters).
• 1234567 — serial number (unique for each motor).

For diesel K9K format may vary:

K9K 8 1234567

Here 8 — engine modification (for example, with or without a particulate filter).

Engine model	Example number	Location	Notes
HR16DE	HR16DE 5XXXXXX	Cylinder block (right)	On E12 it is often covered with a casing
HR12DE	HR12DE 3XXXXXX	Cylinder block (front)	Small print, needs cleaning
K9K (diesel)	K9K 8 7XXXXXX	Front of the motor	Corrodes frequently, check for rust

⚠️ Attention: If the number starts with letters JN1 or SJN - this is not engine number, and part VIN code. Don't confuse them! The VIN is stamped on a plate under the windshield or in the driver's door opening.

How to check the engine number for originality

Checking engine number Nissan Note needed in three cases:

1. Before buying a used car (to prevent theft or engine replacement).
2. When registering with the traffic police (if the number does not match the PTS, an examination will be required).
3. When selecting spare parts (some parts depend on the serial number of the motor).

Verification methods:

• 🔎 Comparison with PTS — the number in the document must completely match the one stamped on the block. If at least one digit differs, the motor has been replaced.
• 📋 Check through the traffic police - send a request on the website traffic police.rf (section "Checking the vehicle"). If the number is not found in the database, this is a cause for concern.
• 🌍 International bases — services CarVertical or Autocheck They will show the history of the motor by VIN and engine number (paid, but reliable).

⚠️ Attention: If the seller refuses to provide access to the engine number or paints it over, this is 100% sign of fraud. Most often, this is how they hide broken license plates after theft or an accident with serious engine damage.

What to do if the number is erased?

If the engine number is not readable, contact an expert organization (for example, NIIAT) to restore the marking. It is prohibited to “restore” the number on your own - this amounts to forgery of documents (Article 327 of the Criminal Code of the Russian Federation).

Decoding the VIN code and connection with the engine number

VIN and engine number Nissan Note are interconnected: by VIN you can determine which engine should be installed on the car initially. VIN format for Note:

SJNFBAJ11U3XXXXXX

Explanation of key symbols:

• SJN — manufacturer code (Nissan Japan).
• F — body type (hatchback).
• B — model (Note).
• J11 — modification (For example, J11 — E11 with HR16DE).
• U — model year (2013 for E12).

To check the engine and VIN match:

1. Find the VIN on the placard under the windshield or in the door opening.
2. Decipher the 8th character (engine):
   • 5 — HR16DE (1.6 l).
   • 3 — HR12DE (1.2 l).
   • 8 — K9K (1.5 diesel).

Compare with the number on the block. If the VIN indicates HR16DE, and it’s knocked out on the engine HR12DE — the engine has been replaced.

⚠️ Attention: If the title indicates one engine, but the VIN should indicate another, this is a reason to refuse the purchase. Such inconsistencies often arise after illegal engine replacement (for example, after a water hammer or a broken timing belt).

What to do if the engine number does not match the documents

The discrepancy between the engine number and the data in the title is a common problem when purchasing Nissan Note with mileage. Possible reasons:

• 🔧 Engine replacement — if the engine has been officially changed, there should be a mark on the PTS. Without it there is a violation.
• 🚨 Number interruption — criminal case (hijacking, dismantling).
• 📝 Error in documents - rare, but it happens (for example, a typo during registration).

Algorithm of actions:

1. Check the history through traffic police or Autocode — if the motor has been changed, there should be a record.
2. Contact the previous owner — Request receipts for engine repairs or replacements.
3. Conduct an examination — if the number is interrupted, this can be seen under a microscope (traces of welding, uneven font depth).
4. Submit changes to the traffic police — if the engine was replaced legally, enter new data into the vehicle title.

Cost of examination: from 3,000 to 10,000 rubles (depending on the region). Without it, registration of a car with a mismatched engine number impossible.

How to protect your engine number from corrosion and counterfeiting

Engine number on Nissan Note often suffers from corrosion (especially on diesel engines) K9K) or deliberate falsification. To protect your markings:

• 🛡️ Apply protective varnish - special formulations (for example, WD-40 Specialist) prevent rust.
• 📸 Take a photo of the number - useful for comparison when selling or checking.
• 🔒 Install an engine immobilizer - will complicate the hijacking and interruption of the number.

What to do it's impossible:

• ❌ Painting a license plate with paint is a violation (fine up to 2,000 rubles under Article 12.2 of the Code of Administrative Offenses).
• ❌ Clean the number with a metal brush - you can erase the numbers.
• ❌ “Recovering” erased symbols yourself is a criminal offense.

If the number is already corroded, try:

1. Process the site rust converter (For example, Tsinkar).
2. Wipe gently soft brush (no pressure).
3. Take photos from different angles - sometimes numbers are only visible under certain light.
