[DelGiselle]

The engine number of a Citroen C-Quatre is located at the right corner of the aluminum casing on the front end of the engine block. It typically consists of a combination of 7 to 8 digits and letters. In addition to the method mentioned above, the engine number can also be found through the following 4 ways: The vehicle's driving license will have the engine number printed, usually on the second-to-last line; The motor vehicle registration certificate will state the engine number; The car purchase invoice will state the engine number; The vehicle purchase tax payment certificate will state 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 range, and engine models can be the same. The engine number, however, refers to the production number of the engine. Each engine can only have one engine number, and every engine's number is unique.
