Honest answers before you download.
- How does a diesel technician differ from a diesel mechanic?
- The titles are largely used interchangeably in most job postings, though 'technician' sometimes implies more emphasis on computerized diagnostics alongside hands-on repair.
- What tools should candidates already be comfortable using?
- Candidates should be comfortable with hand and power tools plus electronic diagnostic scanners; specific OEM software experience is a plus but can often be trained on the job.
