* On the engine itself: The EIN is usually stamped on the passenger side of the engine block, near the front. It may be on a flat surface, or on a raised rib. Look for a metal tag with a series of numbers and letters.
* On the vehicle identification number (VIN) plate: This plate is located on the driver's side dashboard, near the windshield. The VIN contains information about the vehicle, including the engine type.
* In the vehicle's documentation: The EIN should also be listed on the vehicle's registration and title documents.
Note: The EIN is a unique identifier for each engine and is crucial for identifying the specific engine model and its specifications.
