What Does a Diesel Truck Mechanic Do?

Diesel truck technicians carry out the repair and maintenance of diesel engines. Compared to automotive engines, diesel engines power heavy duty machinery such as trucks, busses, bulldozers, and cranes.

As a student in our diesel heavy truck mechanic training program, you will have the opportunity to learn the skills and techniques to become a diesel truck technician from industry-experienced professionals in a hands-on environment.

 

Diagnostic Duties

As vehicle technology becomes more complex, so too do the repairs. For example, technicians will use laptops and software to diagnose problems within electronic systems. They then read and interpret these tests to determine malfunctions and errors occurring in the vehicle’s systems.

Mechanical Duties

Diesel truck technicians work on a variety of repairs including rotating tires, changing oil, checking fluid levels, and replacing malfunctioning parts. They also inspect different parts of the vehicle, including brakes, steering, engines, and transmissions. In addition to this technology, technicians use both power tools and manual tools. Manual tools include wrenches, pliers, and sockets. Power tools include grinding machines and welding equipment.

Electrical Duties

Students will have the opportunity to learn how to inspect and diagnose problems with electrical and electronic systems, including how to use a manufacturer’s PC-based software to diagnose related electronic systems, and how to determine the necessary corrective actions.

Professional Diesel Technician Requirements

STVT’s program is oriented towards two important goals: 

  • Ensuring that our students have the opportunity to learn the skills and proficiencies employers are looking for
  • Preparing our students to sit for a number of important technical and professional mechanic certifications.

Our program prepares students to sit for these certification exams*:

*STVT does not guarantee third-party certifications. Certification requirements for taking and passing certification examinations are not controlled by STVT but by outside agencies and are subject to change by the agencies without notice to STVT. Therefore, STVT cannot guarantee that graduates will be eligible to take certification examinations, regardless of their eligibility status upon enrollment.

Diesel Truck Technician Career Outlook

As diesel cars and lighter trucks become more prevalent, the need for a large pool of skilled workers becomes increasingly necessary. In addition, as freight increases, more diesel-powered trucks may be transporting goods, as opposed to less economical options like trains. Diesel engines are indispensable in today’s economy, making the occupation of a diesel truck technician incredibly valuable.

According to the U.S. Bureau of Labor Statistics, the employment of diesel service technicians and mechanics is projected to grow by 5 percent from 2018 to 2028*.

Where Can a Diesel Mechanic Work?

Diesel technicians are employed in maintenance and repair shops, dealerships, mass transit, vehicle sales and leasing companies, power generating plants, and more. Those that choose can also work as traveling technicians who diagnose and repair roadside and worksite breakdowns.

Another reason to become a diesel truck technician is the opportunity to work with your hands, be on your feet, and on the move. If a typical 9-5 desk job sounds boring to you, then you’re in the right place. As a technician, you probably won’t be sitting at a desk or staring at a computer screen. You will be working in the shop and constantly moving!
