Engine Plant Sequence Number
WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
The engine plant sequence number is located in one place on the engine and is a twelve digit number stamped or laser etched onto the block at the engine assembly plant.
The engine block is marked with the engine plant sequence number on a pad area on the left rear side (1).
