Vehicle Identification Number (VIN)

This is the legal identifier for your vehicle. It appears on a plate in the front corner of the instrument panel, on the driver’s side. You can see it if you look through the windshield from outside your vehicle. The VIN also appears on the Certification/Tire and Service Parts labels and the certificates of title and registration.
Engine Identification
The eighth character in the VIN is the engine code. This code will help you identify your vehicle’s engine, specifications, and replacement parts.
