🔧 Trade Spotlight: Diesel Service Technicians & Mechanics 

“Powering the Machines That Keep America Moving.”

From semi-trucks and buses to bulldozers and boats — diesel engines keep the world running.
Diesel technicians are the people who keep those engines alive.
If you’ve got a steady hand, mechanical curiosity, and don’t mind getting your hands dirty, this trade is a rock-solid career path.

​

What Do Diesel Technicians and Mechanics Do?

Diesel service technicians inspect, maintain, and repair diesel engines and related systems in heavy-duty vehicles and equipment.
They make sure engines run safely, efficiently, and meet environmental standards.

Their work includes:

  • Diagnosing engine problems using test equipment and software

  • Repairing or replacing faulty parts and systems

  • Adjusting fuel injection, timing, and emissions systems

  • Performing regular maintenance and safety checks

  • Using tools like wrenches, grinders, welding machines, and laptops

Diesel techs work on everything from trucks and buses to cranes and marine engines.
The work blends mechanical skill, computer diagnostics, and real-world problem-solving.

​

Work Environment

Most diesel technicians work in repair shops, garages, or maintenance yards — but roadside or on-site repairs are common too.
Shops are usually well-lit and ventilated, but noise, grease, and heavy lifting come with the job.
Technicians spend long hours on their feet, often bending, reaching, or crawling into tight spaces.

Safety matters — protective gear like gloves, boots, and eye protection are part of the uniform.

How to Become a Diesel Technician

Most diesel techs start with a high school diploma or GED, then learn through on-the-job training or technical programs in diesel technology.
More employers now prefer candidates with postsecondary training or industry certifications to prove their skills.

 

Training Covers:

  • Diesel engine systems and repair

  • Electrical, hydraulic, and fuel systems

  • Computerized diagnostics

  • Welding and fabrication basics

  • Safety and environmental regulations

Many technicians earn ASE (Automotive Service Excellence) certification to advance their careers and increase pay.
