Where is the Yuchai engine number located?
4 Answers
The engine number on the Yuchai engine block is located below the oil pump, typically consisting of a combination of 7 to 8 digits and letters. In addition to the above method, the engine number can also be viewed through the following 4 ways: The vehicle's driving license prints the engine number, usually located on the second-to-last line; The motor vehicle registration certificate will state the engine number; The car purchase invoice will state the engine number; The vehicle purchase tax payment certificate will state 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 refers to the production number of the engine, where each engine can only use one engine number and each engine's number is unique.
Last time I helped my friend repair his truck equipped with a Yuchai engine, I carefully looked for the engine number location. Generally speaking, the Yuchai engine number is engraved on the nameplate attached to the engine block, usually located inside the engine compartment—after opening the hood, first check near the side of the cylinder block or the crankcase cover. There’s often a metal nameplate fixed there, clearly displaying the serial number and model. If the nameplate is rusted or missing, the number might also be directly engraved on the cast part of the engine block, near the oil pan. I recommend cleaning the engine surface first and using a high-power flashlight to search, as dust and grease often obstruct the view. Don’t forget to check the vehicle manual—it usually includes diagrams pointing to the exact location. Identifying this number is crucial, as it’s required for repairs or ownership transfers to confirm the engine’s identity. That’s why I always remind vehicle owners to regularly check if the nameplate is intact.
Back when I was driving my Yuchai-powered truck, I spent every day pondering maintenance details. I learned the engine number's location from the vehicle manual—it's fixed on a small metal plate on the upper side of the engine block, near the fan side. You can spot it by crouching down to look under the engine. Once during maintenance, I noticed the plate had rusted, making the number nearly illegible. Fortunately, I cleaned it up with rust remover. The actual method is simple: after turning off the engine, open the hood and feel around the connection between the cylinder block and the bracket. There's usually a raised or attached plate there. On newer vehicles, the number is clearer; older ones might require careful inspection of the engraving. Once found, jot down the number for future use—it comes in handy during annual inspections or part replacements.
When I first encountered Yuchai engines, I was curious about where the engine number was located. In most cases, it's on the nameplate attached to the engine casing, typically positioned in the engine compartment near the top or side, such as around the cylinder head. To find it, start by opening the engine cover and visually scanning the metal surfaces. Sometimes the nameplate may be loose or covered with dirt, requiring a wipe with a cloth for better visibility. Remember, the vehicle manual also provides detailed descriptions of its location—keeping a record can save you trouble later. It's a straightforward task to get started with.
