Where is the engine number located on the BYD S7?

BYD S7's engine number is located on the cylinder block. You need to remove the engine cover and look towards the underside of the engine on the opposite side of the battery to find it. The engine model number is an identification code assigned by the engine manufacturer in accordance with relevant regulations, corporate or industry practices, and engine attributes. It represents information such as the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine. The BYD S7 is BYD's new mid-to-large-size SUV, featuring a three-dimensional and dynamic design with sharp yet elegant lines that perfectly balance aerodynamics. The hawk-eye headlights are striking, complemented by window frame bright trims and a chrome grille, creating a wavy, sophisticated, and premium overall appearance.
I bought a BYD S7 last year and have done quite a bit of tinkering myself, so finding the engine number is a breeze for me. It's located under the hood—open the engine hood, stand at the front of the car looking downward, and you'll find a small metal tag with the number printed on the front or left side of the engine block, usually near the air filter. The first time I looked for it, it took me over half an hour, squatting down and almost straining my back. Later, I realized using a phone flashlight helps when the lighting is poor. This number is crucial for verification during transfers or maintenance, as mistakes can easily happen otherwise. Remember to clean the engine compartment regularly to prevent dust from covering the tag—I usually wipe it every three months and check for loose wires while I'm at it. If you can't find it, refer to the detailed diagram on page 32 of the user manual, or take a photo and keep it on your phone for easy access anytime.
As a seasoned mechanic specializing in domestic vehicles, I've dealt with the BYD S7 engine number issue dozens of times. It's fixed on the right side of the engine block—just open the hood, and you'll find the number engraved on the metal plate at the front of the engine, near the driver's seat side. When checking, don't start the car; simply open the hood, crouch down, and take a quick look. If it's dirty, clean it to see clearly. This number is the engine's unique identifier and must be accurate for maintenance records or ownership transfers. I recommend owners regularly check for rust or wear and protect the label with tape if necessary to avoid costly repairs due to errors. If the engraving becomes faint and hard to read, try verifying it with the vehicle registration documents.
