Where is the engine number located on a Cadillac?

[NoraLynn]

Cadillac's engine serial number is located on the side of the flywheel end flange surface of the engine block. In addition to the above method, the engine number can also be viewed in the following 4 ways: The vehicle's driving license displays the engine number, usually located on the second-to-last line; The motor vehicle registration certificate will indicate the engine number; The car purchase invoice will show the engine number; The vehicle purchase tax payment certificate will indicate the engine number. 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 lineup, and engine models can be identical. The engine number, however, refers to the production serial number of the engine. Each engine can only have one unique engine number, and no two engines share the same number.
