Jianghuai Refine S3's engine number is located on the left side of the engine, on the nameplate in the engine compartment, under the vehicle identification number column. The model number consists of the following 4 parts: 1. Prefix: Includes product series code, generation symbol, and regional/enterprise code. Manufacturers may choose appropriate letters as needed, but must obtain approval and filing from the industry standard regulatory body; 2. Middle section: Composed of cylinder count, cylinder arrangement type, stroke, and cylinder diameter symbols; 3. Rear section: Consists of structural feature symbols and usage feature symbols; 4. Tail section: Used to distinguish improved versions within the same series, manufacturers may select appropriate symbols, with a "-" potentially separating the rear and tail sections.

Recently, while helping a friend locate the engine number of his JAC S3, I went on this little adventure. The number is located in the engine compartment and can be seen after opening the hood. It's engraved as a string of digits on the front side of the engine block, often covered in dust, so you'll need to gently wipe it clean with a cloth to see it clearly. The first time I tried without gloves, I accidentally burned my hand—a reminder to everyone to wait at least half an hour for the engine to cool down before attempting this. Safety comes first. This isn't just about vehicle registration or transfer procedures; it's also useful for spotting issues like oil leaks or cracks during routine maintenance. I always take a photo of the number with my phone and save it for future reference—it makes things much easier during the next service or when selling the car, saving me from having to crouch down and search for it every time. The owner's manual actually has detailed diagrams, but hands-on experience is more fun and has helped me develop a habit of regularly cleaning the engine compartment.

As an experienced maintenance technician, I can tell you that locating the engine number on the JAC S3 is quite straightforward. It's clearly engraved on the front section of the engine block within the engine compartment. After opening the hood, you'll need to bend down for a closer look - the number is typically stamped in a single line on the cylinder block surface. I've seen many car owners try to scratch it out with their fingernails, which can cause damage, so I recommend using a soft brush or cloth to clean the surface instead. If the number appears faded, you can cross-reference it with the vehicle identification plate to verify consistency. This isn't a minor detail - it can help you avoid fraud when purchasing or servicing the vehicle. At our repair shop, we routinely assist customers with this process while also cleaning carbon buildup areas, which allows for early fault detection and helps keep the vehicle running longer and more reliably.

Before purchasing the JAC S3, I did thorough research and learned that the engine number is located on the front side of the engine block. It is directly visible after opening the hood, and I copied it down in my notebook to compare with the vehicle documents to prevent counterfeit issues. The actual position is slightly closer to the fan on the front side of the car, and a flashlight is needed to see it clearly in low light. This number is crucial for registration and insurance, so it cannot be taken lightly. Due to my lack of experience initially, I overlooked this step once, causing a delay in the transfer process. Since then, I always take photos as backup. A few simple steps—cleaning and verifying—can save a lot of time and effort. Now, during every vehicle inspection, I prioritize confirming this detail to ensure my car remains legally transparent.
