Where exactly is the engine number on the Nissan Almera G15

On Nissan Almera G15 (in the back N17, aka G15 for the Russian market) the engine number is stamped in two possible places - depending on the year of manufacture and modification. Main location:

• 🔧 On the cylinder block on the right (in the direction of travel) - next to the oil filter. The number is stamped on a special area, often covered with dirt or corrosion.
• 📍 On the front of the block — closer to the gearbox, under the thermostat. Visible only when the protection is removed or using a mirror.

Important: on models 2019–2026 the number may be duplicated on a metal plate under the hood (next to the VIN), but this does not replace the main marking on the block! If you do not find the number in the specified locations, check:

• 🔦 Lighting: Use a flashlight with a narrow beam - the number is often hidden in the shadows.
• 🧹 Cleanliness: The plate with the number may be covered with a layer of oil or road dirt. Clean it with a solvent (eg WD-40).
• 🔍 Viewing angle: Sometimes the number is only visible from a certain angle - try using a mirror on the telescopic handle.

3. Remove the engine protection (if any): on most Almera G15 protection is secured with 4–6 bolts 10 mm.
4. Clear the pad with the number: Spray solvent and wipe with a cloth. Do not use hard brushes - they can erase the numbers!
5. Use a mirror: Shine the flashlight at an angle and look at the number in the mirror. An alternative is to take a photo of the site and enlarge the photo on your phone.

If the number is still not visible, check alternative locations:

Inspect the left side of the cylinder block (rare, but happens on early batches of 2013–2014)

Check the metal plate on the front bulkhead under the hood (duplicate, not the main number!)

Use an endoscope to inspect hard-to-reach areas under the thermostat

Check the VIN code - the first 3 characters of the engine number must match 4-6 characters of the VIN-->

Critical detail: On HR16DE engines after 2020, the number may be laser engraved instead of punch-stamped. Such numbers are almost invisible without special lighting!
