The engine number of the Geely Vision X3 can be found on the plane where the cylinder block and the transmission housing meet, at the lower left side of the front end of the engine. It usually consists of a combination of 7 to 8 digits and letters. In addition to the method mentioned above, the engine number can also be checked in the following 4 ways: The vehicle's driving license has the engine number printed on it, usually located on the second-to-last line; The motor vehicle registration certificate will indicate the engine number; The car purchase invoice will indicate the engine number; The vehicle purchase tax payment certificate will indicate the engine number. It should be noted that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer, and engine models can be the same. The engine number, however, refers to the production number of the engine. Each engine can only have one engine number, and the number of each engine is unique.

I remember helping a friend locate the engine number on his Geely Vision X3. We spent quite a while crawling under the car searching for it. The engine number is actually engraved on the engine block, near the connection point between the engine and transmission, close to the exhaust pipe side. You'll need a strong flashlight to look upwards - there's a row of raised alphanumeric characters there. Just be careful not to reach in right after turning off the engine, as the exhaust pipe gets hot enough to roast sweet potatoes. Some owners take the easy way out by going directly to the DMV for a rubbing - the staff will press an inked rubber pad against that spot to make an imprint of the number. If checking it yourself, I recommend wearing gloves since the engine compartment tends to be quite greasy.

Last time I went to the 4S shop for maintenance, the mechanic pointed it out to me under the chassis. The engine number of the Vision X3 is indeed located on the back of the engine block, near the firewall. To see it clearly, you need to lift the car up or find an inspection pit to crawl under. That spot is particularly prone to getting covered in mud—I've seen people spend ages scrubbing it with a toothbrush dipped in carburetor cleaner. Nowadays, new car engine numbers even come with a QR code; you can scan it with a barcode reader to access the vehicle information. However, for regular owners who want to verify it themselves, they can just copy the number from the vehicle license or registration book and compare it with a flashlight.

I've encountered this issue when helping a neighbor with vehicle transfer. The engine number is usually engraved on a lower platform on the side of the cylinder block, in an extremely awkward position - you have to reach through the narrow gap between the generator pulley and the vehicle frame. Older folks simply can't reach it, so it's best to find a young helper. Pay special attention to distinguishing between 0 and O when recording the number - last time a vehicle owner mistakenly wrote O instead of 0 on the rubbing, and the DMV absolutely refused to process the paperwork. It's easier to operate when the engine is cold in winter, as the nearby exhaust manifold can reach nearly 100 degrees when the engine is hot.
