Diesel Mechanic Programs

From semi-trucks to construction equipment, diesel engines drive many of the most powerful moving machines. However, not just any mechanic can work on these engines. Diesel technicians and mechanics provide specialized service doing the following:

  • Using technical charts and manuals to plan work procedures
  • Inspecting components of diesel engines and vehicles, including brakes, steering mechanisms and transmissions
  • Diagnosing mechanical problems
  • Repairing or replacing malfunctioning parts
  • Providing maintenance services such as changing oil and rotating tires

Diesel Mechanic Specializations

A diesel mechanic school provides the knowledge needed to work on a variety of vehicles, but some mechanics want to specialize their career. The following are some examples of specializations pursued by graduates of diesel mechanic trade schools.

  • Diesel auto mechanics. These diesel service technicians inspect, repair and maintain auto engines to ensure they run smoothly.
  • Bus and truck mechanics. As their title suggests, bus and truck mechanics tend to specialize in larger diesel engines. Often these vehicles are subjected to higher loads and run-times than passenger cars and require special care.
  • Small engine diesel mechanics. Small engine mechanics repair and maintain diesel engines in motorized power equipment like motorcycles and boats.
  • Heavy vehicle diesel technicians. These mechanics specialize in larger machinery such as construction equipment, farm tractors and diesel trains.

How to Become a Diesel Mechanic

At one time, diesel mechanics weren't expected to have any education beyond a high school diploma. While there are still some jobs available for those without a postsecondary education, employers are increasingly looking for graduates from diesel mechanic trade schools. In general, expect to need the following:

  1. Earn a high school diploma, though this is not always necessary.
  2. Complete training in a degree or certificatte program for diesel mechanics.
  3. Stay up to date with certification sometimes required by employers.

Having a formal education means less on the job training is needed and helps ensure new workers have a good grasp of all the following:

  • Basics of diesel technology
  • How to read technical manuals
  • Diagnostic and repair techniques

Degree programs for diesel mechanics

To become a diesel mechanic, you can earn a degree or complete a non-degree postsecondary program. Both can provide the knowledge needed to begin a career in the field. Here's a look at each option:

  • Diploma/Certificate: A diploma or certificate is a common level of education for diesel mechanics. If you're concerned about how long is diesel mechanic school, the good news is that these postsecondary programs can often be completed in less than a year. Diploma and certificate programs teach all aspects of diesel vehicle maintenance and repair and some even provide specialized training for those who want to become experts in working with engines from a particular manufacturer.
  • Associate Degree: Although less common, some mechanics choose to earn an associate degree in diesel technology or a similar field. These programs cover much of the same material as a diploma or certificate but may delve into more advanced concepts related to engine design and shop management. An associate degree typically takes two years to earn.

Diesel mechanic schools

You can find diesel technology programs at dedicated trade schools as well as community colleges. Since diesel mechanics have a hands-on job, most programs provide in-person training.

While you can find a diesel mechanic school online, distance education programs may not provide hands-on instruction. However, some online diesel mechanic schools offer hybrid programs which can be the best of both worlds. These programs may allow students to take online classes that are complemented with face-to-face instruction.

Diesel mechanic certification

While not required to work as a diesel mechanic, many employers prefer to hire those who have become certified. The National Institute for Automotive Service Excellence, known as ASE, offers what is considered the standard level of diesel mechanic certification. Those working with diesel technology can earn an Electronic Diesel Engine Diagnosis Specialist certification or be certified in one of the following areas for medium and heavy trucks:

  • Diesel Engines
  • Drive Train
  • Brakes
  • Suspension & Steering
  • Electrical/ Electronic Systems
  • Heating, Ventilation & Air Conditioning (HVAC)
  • Preventive Maintenance Inspection

Career advancement for diesel mechanics

Certification is a key ways to advance a career as a diesel mechanic. Earning specialty certifications may open the door to new job opportunities. Some mechanics also obtain a commercial driver's license so they can fill jobs requiring test drives.
