Finding the Engine Identification Number on a Crossover Nissan Qashqai the first generation (J10 body) often causes difficulties for car owners, especially when preparing for a technical inspection or selling a car. Unlike the easily accessible VIN numbers on the windshield, the power plant markings are hidden in hard-to-reach places under the hood, which requires the owner to carefully prepare and have high-quality lighting.
Understanding what it looks like unit marking, what symbols it contains and where exactly it is stamped is critical to verifying the legal purity of the machine. Errors in the transcription of even one letter can lead to refusal of registration with the traffic police, so it is necessary to approach the identification process with maximum responsibility and attention to detail.
Location of markings on the cylinder block
The main place for applying the engine number Nissan Qashqai J10 - this is a special nameplate or direct engraving on the cylinder block. For most gasoline engines of the series HR16DE and MR20DEinstalled on this model, the plate is located in the front of the engine, closer to the radiator, but is often covered with plastic covers or brackets for attachments.
For a visual inspection, you will need to remove the plastic trim if it is obstructing your view and use the handle mirror to view the underside of the pad. On the plate riveted to the block, you will see two lines: the top one contains the letter code of the motor model, and the bottom one contains a unique serial number. Sometimes the number is stamped directly onto the metal, making it more resistant to corrosion and counterfeiting attempts.
If you plan to check it yourself, be sure to clean the area around the sign from dirt and oil stains. Dirt can obscure the final numbers or make them unreadable, creating problems when reconciling data. Use a brush and degreaser, but be careful not to damage the marking itself or the sensitive sensors nearby.
Types of engines and their marking features
Depending on the year of manufacture and sales market, on Nissan Qashqai J10 various modifications of power units were installed, each of which has its own specific number. The most common is the naturally aspirated engine. HR16DE volume of 1.6 liters, which is reliable and economical. Its number plate is usually located on the front cover of the cylinder block.

It is also worth considering diesel versions with a motor M9R, where the number may be located in another location, for example, on the cylinder block on the gearbox side, which requires the removal of some components for visual inspection.
It is important to distinguish between factory markings and additional stickers that are often found in the engine compartment. These stickers contain information about routine maintenance or oil specifications, but they are not legally significant for engine identification. Always rely only on the stamped number or riveted metal plate.

The second part of the number is the serial index, which is assigned to each unit individually during assembly. It is this digital sequence that is checked against the data in the PTS and the registration certificate. When reading, pay attention to the similarity of symbols: letter I can be taken as a number 1, and the letter O per figure 0, which is a common cause of errors when filling out documents.

- 2.0 (MR20DE)
- 2.0 Diesel (M9R)
