The engine number of the Toyota Crown is located on the right side of the engine block, at the junction between the engine body and the oil pan. In addition to the method mentioned above, the engine number can also be checked through the following four ways: The vehicle's driving license contains the engine number, usually found on the second-to-last line; The motor vehicle registration certificate will state the engine number; The purchase invoice will include the engine number; The vehicle purchase tax payment certificate will also indicate the engine number. It is 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 product line, and multiple engines can share the same model. On the other hand, the engine number is the production serial number of the engine, with each engine having a unique number that cannot be duplicated. The engine number consists of four parts, each representing different meanings. The first part includes the product series code, generation symbol, and regional or manufacturer code, which are selected by the manufacturer as needed and must be approved and recorded by the industry standardization body. The middle part is composed of symbols representing the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. The rear part includes symbols for structural and usage characteristics. The tail part is a distinguishing symbol, used by the manufacturer to differentiate between improved or modified versions of the same series.
