Diesel service technicians and mechanics inspect, repair, and overhaul buses and trucks, or maintain and repair any type of diesel engine.
Diesel service technicians and mechanics usually work in well-ventilated and sometimes noisy repair shops. They occasionally repair vehicles on roadsides or at worksites. Most diesel technicians work full time, and overtime and evening shifts are common.
How to Become a Diesel Service Technician or Mechanic
Most diesel service technicians and mechanics learn informally on the job after a high school education, but employers increasingly prefer applicants who have completed postsecondary training programs in diesel engine repair. Although not required, industry certification can be important for diesel technicians.
Employment of diesel service technicians and mechanics is projected to grow 12 percent from 2014 to 2024, faster than the average for all occupations. Job opportunities should be best for those who have completed postsecondary training in diesel engine repair.
