Where to Find the Engine Model Number?
2 Answers
Engine model numbers can be found near the spark plugs on the left side of the engine. These numbers are identification codes assigned by the engine manufacturer in accordance with relevant regulations, industry or corporate conventions, and engine attributes to represent information such as the manufacturer, specifications, performance, features, technology, intended use, and production batch of a series of identical products. Engine model numbers consist of three parts: 1. Prefix: Composed of self-selected letters; 2. Middle section: Includes symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter; 3. Suffix: Composed of symbols indicating structural and usage characteristics.
I remember once helping a friend fix their car, and only when the engine had issues did I realize how crucial the location of the model number is. First, open the engine hood—there's usually a small metal plate on the engine block itself, engraved with the engine model and serial number, which is the most straightforward method. Second, check the Vehicle Identification Number (VIN), located on a label at the lower-left corner of the windshield or on the B-pillar. The 7th to 8th characters of the VIN can reveal specific model details. Additionally, the owner's manual has a dedicated page listing all key component specifications. My advice? Take photos during routine maintenance for reference. Different models affect part replacements, such as horsepower output—overlooking these details can cost you time and money.
