Where is the engine serial number located on the Mazda6?

[PatrickDella]

The engine serial number on the Mazda6 is located on the engine block. You need to open the front engine compartment, and you can find it on the lower left side of the engine. It is illegal to alter the engine serial number of a vehicle without authorization. In case of damage, you should contact the vehicle management office or the traffic management department of the public security authority. The meanings represented by the car engine number are as follows: 1. Front part: Includes product series code, generation symbol, and regional or enterprise code, which are selected by the manufacturer as needed and must be approved and filed by the industry standard regulatory body. 2. Middle part: Consists of the cylinder count symbol, cylinder arrangement symbol, stroke symbol, and cylinder bore symbol. 3. Rear part: Comprises the structural feature symbol and the usage feature symbol. 4. Tail part: Differentiation symbol. When differentiation is needed due to improvements or other reasons within the same product series, the manufacturer selects an appropriate symbol to represent it, and the rear part and tail part can be separated by a hyphen (-).
