The engine identification number provides engine information with regards to engine type (1st digit), engine displacement (2nd and 3rd digits), design sequence (4th digit), and manufacturing sequence (1th through 10th digits).
The 2nd and 3rd digits in the engine identification number indicate the engine displacement in liters. Therefore, a code of 18 indicates that the engine displacement is 1.8L.
The engine identification number is stamped onto the left-hand side of the engine block near the flywheel.
