What should a technician do if the engine size differs from the under-hood emission label?

• A. The technician should check to see if that engine was offered for that vehicle that year
• B. The technician should update the label
• C. The technician should ignore the difference
• D. The technician should replace the engine

Answer: (A)

When the engine size on the under-hood emission label doesn’t match the actual engine, the technician’s first step is to verify whether that engine was offered for that vehicle model and year. The label’s displacement reflects the certified configuration for that specific year, so confirming the factory options helps determine if the mismatch is an authorized variation or a non-conforming setup. If that engine was indeed offered for that year, you can proceed using the appropriate certification and documentation for that configuration. If it wasn’t offered, you’d follow the proper procedures for non-conforming configurations rather than trying to adjust the label or ignore the difference.
