Where can the engine ID tag be found?

• A. On the engine block
• B. Inside the drivers door
• C. Under the seat
• D. In the glove box

Answer: (B)

Engine identification data is carried on a data plate that the technician reads without needing to open the hood. This tag is placed where it’s easy to access when the door is open, typically in the driver's door jamb, so you can quickly read the engine code, serial number, and other identifiers. That accessibility is why the driver's door area is the correct place for the engine ID tag. The engine block may have stamped numbers, but those aren’t the standardized tag used for identification. The glove box or under the seat aren’t typical spots for the engine ID tag.
