How to Check the Engine Serial Number?

Under the B-pillar on the passenger side, open the door to see it. This nameplate only specifies the year and month. The nameplate also notes the vehicle's chassis number. Additionally, the certificate of conformity that comes with the new car is located in the upper right corner of the certificate. The production date indicated here can be precise to the year, month, and day. Related precautions for engine disassembly: 1. Disassemble after the engine cools down: Disassembling after the engine cools down makes it easier to remove parts and prevents deformation during disassembly, as high temperatures weaken rigidity, making parts prone to deformation. 2. Avoid deforming the oil pan during removal: The Wuling B-series engine uses an iron oil pan, which is difficult to remove due to the adhesive on it. Avoid forcing it open at high temperatures to prevent deformation, which could lead to oil leaks after reassembly. The best method: Use specialized tools for removal. 3. Remove bolts in sequence: Removing bolts in order prevents breakage or deformation during disassembly. 4. Use specialized tools for inspection: After engine disassembly, each component needs to be inspected. Many experienced mechanics rely on visual or tactile methods, but for beginners or those with less experience, professional tools are necessary (and this is also the most accurate and recommended method). Follow the repair manual's instructions and use tools such as calipers, micrometers, and dial indicators.
Finding the engine serial number is like a treasure hunt! It's usually hidden in the engine bay, most commonly on the metal surface of the engine itself, displayed either as stamped digits or on a label. First, pop open the hood, find good lighting, and check the engine cover or the side of the block. From my experience with several cars, Japanese brands like Toyota often place it on the left-side cover, while European or American models like Volkswagen might have it near the front bottom. Sometimes the number is covered in dust—just gently wipe it clean with a small brush or cloth. Never touch the engine when it's hot to avoid burns. This number is crucial for matching genuine parts or vehicle registration, so after noting it down, snap a photo and save it on your phone. If you can't locate it, check the owner's manual or sometimes even the vehicle's underbody for reference.
Observing the engine serial number reminds me of playing a puzzle game. It's usually located in a visible spot within the engine bay, but varies greatly across different models: sedans like Honda place it near the intake manifold, SUVs like Land Rover position it on the firewall side, while trucks may hide it deeper. I recommend bringing a flashlight or phone light for inspection—the stamped digits include serial and code numbers, with alphanumeric combinations easily causing confusion. Additionally, new vehicles typically display it clearly on the hood label, whereas older cars might have it obscured by grime, requiring cleaning. While searching, take the opportunity to check fluid levels for maintenance, as the number is useful for verifying VIN records or warranty information to prevent overcharging during repairs. Always record the complete number to ensure accuracy and avoid mistakes.
