Where is the car engine number located?

The engine number is generally found on the outer surface of the engine block, or on the vehicle's nameplate, the nameplate inside the engine compartment. You can also check the engine number on the car purchase invoice; the factory certificate includes the engine number; for commercial vehicles, the operation permit can be used to query the engine number; the vehicle purchase tax payment certificate contains the engine number; the public security authority's registration records have the engine number; the vehicle insurance card lists the engine number; it can also be found below the windshield directly in front of the driver's seat. The simplest and most direct method is to check the vehicle's administrative green book or the vehicle registration certificate. The engine number is like a person's ID number, representing each individual vehicle. It stores very important information about the vehicle. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, industry or enterprise practices, and the engine's attributes, for a batch of identical products. It indicates information such as the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine, including details like fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose passenger vehicles are marked with the professional manufacturer's name, model, and production number as required. It's important to note 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's product line, and multiple engines can share the same model. The engine number, however, refers to the production number of the engine, with each engine having a unique number that cannot be duplicated. Composition of the car engine number: Front section: Includes the product series code, generation symbol, and regional or enterprise code, which the manufacturer can choose as needed, but must be approved and recorded by the industry standard's regulatory body. Middle section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Rear section: Comprises symbols for structural features and usage characteristics. Tail section: Distinguishing symbols. When differentiation is needed within the same series due to improvements or other reasons, the manufacturer selects appropriate symbols to indicate this, with the rear and tail sections possibly separated by a hyphen.

I previously encountered a situation where I couldn't find the engine number, but eventually a mechanic helped me solve it. The engine number is usually engraved on the engine block itself, but its location varies significantly depending on the vehicle model. For ordinary cars, you can find it by opening the hood and looking along the front of the car at the side of the cylinder block. However, some cars require removing the intake manifold cover to see it. German cars often have the number stamped on the rear side of the engine near the cabin, while Japanese cars mostly have it on the front side of the engine. If you're looking for it yourself, remember to do it when the engine is cold. Use a flashlight to search for the metal nameplate, and if it's covered with grime, clean it with carburetor cleaner. This number is particularly important—it's used for vehicle transfers and annual inspections, so it's best to take a photo and save it on your phone for backup. If you really can't find it, don't force it—a professional repair shop can handle it in about twenty minutes.

Finding the engine number requires patience, as its location varies significantly across different model years. Older vehicles typically display it openly on the front or top of the engine, while newer models often conceal it in harder-to-reach spots. Last time I helped a friend locate the engine number on a Ford, it was actually near the firewall at the bottom of the engine block – we had to use a smartphone camera to photograph it. A pro tip: always carry a high-powered flashlight. Some German cars even require removing the engine cover. Don't panic if you can't find it immediately – the complete number is also printed on the vehicle's VIN plate (usually on the door jamb) and registration documents. Crucially, watch out for burns – engines stay extremely hot after shutdown. If obstructions make access difficult, it's smarter to visit a repair shop rather than risk damaging wiring by forcing tools into tight spaces.

During my last vehicle inspection, I was asked to provide the engine number, and I spent quite some time searching around the engine bay. The typical location is on the metal surface at the front of the engine, but it can be tricky to find: some are on the left side of the cylinder block, while others are hidden behind the alternator. I recommend checking the vehicle owner's manual first—many cars now come with a dedicated inspection mirror stored in the glovebox. It's best to wear gloves during the process and use a towel to clean off any oil or dirt. If the number is unclear, try making a rubbing—press tape lightly over the digits to create an imprint. This number is crucial for vehicle identification and is required for buying, selling, or transferring ownership, so make sure to record it accurately. If you notice any signs of tampering with the number, report it to the police immediately.

I remember spending half an hour searching for the engine number on my first car, but there's actually a pattern to follow. For small-displacement engines, it's usually located on the upper middle front side, while larger engines often have it positioned on the side. German cars tend to place it near the exhaust manifold, whereas Japanese models typically position it around the timing belt cover. The key is to locate the rectangular metal plate with embossed digits. Before starting, it's wise to clean the engine bay dust and keep a dental mirror handy for inspecting tight spots. This number serves as the engine's ID and is strictly checked during annual inspections and ownership transfers. Avoid using hard objects to scrape the numbers as damaging the engine would be troublesome. If you really can't find it, dealerships can quickly locate the rubbing position for you.
