This metal or plastic plate features a sequence of characters known as VIN plate symbols, each representing specific vehicle details.
Look closely at the VIN plate symbols to locate the engine size information. Sometimes, the engine size is displayed as a code within this sequence, which corresponds to your car’s engine specifications. If the engine size isn’t directly listed, the engine compartment labels near the VIN plate might show the engine displacement or model details.
Use Online VIN Decoding Tools to Find Engine Size
If you can’t find the engine size on the VIN plate or engine compartment labels, you can use online VIN decoding tools to get the information you need. These tools let you enter your VIN and quickly reveal detailed engine specs. They’re great for vehicle maintenance and car insurance decisions.
They’re especially handy if you want accurate info without digging under the hood.

Look for Engine Size on the Engine Block
When you want a direct and reliable way to find your car’s engine size, checking the engine block is a solid approach. The engine block usually has stamped markings that provide specific details about the engine, including its size.
These engine block markings can be found by opening the hood and inspecting the engine bay carefully. Sometimes, engine bay labels also display this information, but the engine block markings are often more precise.
Here’s a quick guide to help you identify engine size from the engine block markings:
| Location | What to Look For |
|---|---|
| Front of engine | Stamped numbers or codes |
| Side of engine | Engraved size or displacement |

Look closely for combinations of numbers and letters. The displacement is usually in liters (e.g., 2.0L) or cubic centimeters (cc). This method guarantees you get accurate engine size info directly from the source.
Check the Emissions or Under-Hood Sticker for Engine Size
You can find your engine size on the emissions sticker or the under-hood label, which is usually located near the engine bay. Take a close look at these stickers because they often have detailed engine specifications listed by the manufacturer.
This info usually includes the exact engine displacement you’re after, so it’s a handy place to check if you want to know your engine size.
Locate Emissions Sticker
Although it might seem hidden at first, the emissions sticker is one of the easiest places to find your car’s engine size. This sticker provides essential details about emission standards and engine specifications required by law.
To locate it, check common sticker locations like the inside of the driver’s door frame, under the hood near the radiator support, or on the firewall. The sticker clearly lists engine displacement alongside other crucial information, making it a reliable source.
Since emission standards vary by model year and region, this sticker guarantees your engine size matches regulatory requirements. By knowing the exact sticker location, you save time and avoid guesswork when identifying your engine size quickly and accurately.
Read Under-Hood Label
Finding the emissions sticker near the driver’s door is a great start, but there’s another label under the hood that can confirm your engine size. Open the hood and look for the under hood label, usually located on the underside of the hood or along the front of the engine compartment.
This label often includes crucial information such as engine displacement, engine type, and sometimes horsepower ratings. By checking this under hood label, you get a direct reference to your car’s engine size without guesswork.
Be sure the engine compartment is cool and well-lit so you can read the label clearly. This step gives you a reliable source to verify engine details and complements the information found on the emissions sticker.
Identify Engine Specifications
When checking your car’s engine size, the emissions or under-hood sticker provides key specifications you can rely on. This sticker usually lists essential details that help you understand your engine’s capacity.
Knowing this aids in proper car maintenance and ensures ideal engine performance. Look for terms like “Engine Displacement” or “Engine Size” to find the exact number.
