What Is a Diesel Technician?
A Diesel Technician — also known as a diesel mechanic — is a skilled professional who inspects, maintains, and repairs diesel engines and systems. These engines power a wide range of vehicles and machinery, including:
-
- Commercial trucks and buses
-
- Construction and agricultural equipment
-
- Marine vessels and generators
-
- Railroad and public transportation fleets
Diesel techs use a mix of hands-on tools and diagnostic technology to troubleshoot issues, perform routine maintenance, and keep essential equipment running smoothly. It’s a hands-on, high-demand career where no two days are the same — and your skills are always in demand.
