As a diesel mechanic, you'll work on the upkeep, overhaul, and general service of diesel-based vehicles such as trucks, buses, trains, and other vehicles with diesel-powered engines. Diesel mechanics do on the upkeep and repair of heavy machinery, too: machines such as cranes, bulldozers, and tractors.
You’ll typically work in a single fixed location, but some mechanics are required to travel to remote worksites to service vehicles.
Your work as a diesel mechanic is not confined just to the road, however. Diesel engines are in many different types of boats, many of which need an on-board diesel mechanic to monitor and service them. In addition, many corporations use backup generators with diesel engines to maintain power in case of an interruption. These companies typically need an onsite diesel mechanic to perform quick repairs.
The Day-To-Day Of A Diesel Mechanic
Your job is to monitor, inspect, maintain, and repair diesel engines. As such, you’ll do everything from routine oil and fluid changes to total engine rebuilds. Because diesel engines are worked hard and mechanically stressed, the job outlook for mechanics who repair them is good—you will always be needed to do fixes and maintenance.
Diesel mechanics work most closely with:
- The electrical system of vehicles
- The entire engine build and the parts that correspond with it
- Diagnostic computer software
- Brake systems
When a repair is needed, you will diagnose the problem and get the appropriate replacement parts. You might use pneumatic tools when diagnosing and repairing, as well as welding equipment. You'll definitely various hand-held tools, such as screwdrivers and wrenches.
Most modern vehicles have advanced computers inside of them. To repair most modern diesel engines, you are going to need to have experience with and knowledge of in-vehicle computers, processors, and other electronic parts.

- Diesel engines and fuel systems
- Climate control
- Preventative maintenance
- Electronic technologies in diesel vehicles
- Refrigeration transport
