Methods to check the car engine number: 1. The engine number is listed on the vehicle license; 2. Check the engine number in the motor vehicle registration certificate; 3. Find the engine number on the car purchase invoice; 4. The factory certificate contains the engine number; 5. Check the engine number on the operation certificate for commercial vehicles; 6. The vehicle purchase tax payment certificate includes the engine number; 7. The engine number is recorded in the public security registration records; 8. The vehicle insurance card has the engine number; 9. The actual engine bears the engine number. The engine number is unique—each motor vehicle has a separate engine, which carries specific details such as the engine model, production date, and origin code. It is crucial vehicle information that must not be altered or replaced.
I remember it was quite a hassle when I first tried to locate the engine number. In the end, it was the mechanic who showed me how. The most straightforward method is to open the hood and look for the engraved alphanumeric combination on the engine block itself, usually located on the side or top of the cylinder block. For example, Toyota engines often have it near the alternator. If it's hard to see, you can wipe off the grease with a damp cloth and use your phone's flashlight to take a photo. However, the engine number is actually printed clearly on the vehicle registration certificate—just flip to the 'Engine Number' section. For older cars with rusted nameplates, you might need to visit the DMV to access the records, as they have professional spotlight equipment. By the way, don't confuse the engine number with the VIN (Vehicle Identification Number), which is stamped on the lower left corner of the windshield.
When helping my neighbor transfer the ownership of an old car, I had to locate the engine number. The stamped number on that vintage Santana was nearly obscured by grime. The standard procedure is to first check the second page of the vehicle registration certificate, but during the actual inspection, you need to verify it against the physical part. I recommend bringing a piece of chalk: open the engine hood and rub the chalk over the flat surface of the engine block, and the raised numbers will become visible. For American cars, the number is usually located behind the radiator, while for German cars, it might be hidden beneath the intake manifold. If you can't find it, don't scrape forcefully—last time, I accidentally loosened the sensor wire on my neighbor's car and ended up spending 200 yuan to clear the fault code. Nowadays, new car owner's manuals come with diagrams, so checking the manual before taking action saves a lot of trouble.
