Diesel mechanics are responsible for the repairs, maintenance and overall care necessary to keep diesel vehicles running. This includes bulldozers, trucks, boats, and buses. They may work in well-ventilated indoor shops or outdoor shops exposed to elements such as extreme heat and humidity or cold and aridity. They may specialize in inspecting and overhauling one vehicle such as a school bus or certain truck brand. Typical employers and industries include federal, state and local governments, mass transit, freight trucking and vehicle wholesaling. Many people choose this career because of the entry requirements and the diesel mechanic salary.

Education and Training

Education requirements will differ from employer to employer. Federal government agencies, for example, may have stricter standards than the family-owned boat repair shop in your town. Entry-level positions typically require no more than a high school diploma. If competition is fierce in your local area, look at attending a college or university that offers certificate programs or Associate’s degrees with a specialization in diesel mechanics. Trade or vocational schools may offer more hands-on training and cost a lot less. Look for programs that teach you systems such as the vehicle’s fuel and electrical system and become familiar with the diagnostic software. More vehicles than ever are computerized and can self-diagnose if you know how to read the reports.


The National Institute for Automotive Service Excellence, or ASE, has been certifying mechanics for over 30 years. Passing an ASE exam specifically for diesel vehicles and heavy equipment proves you have the overall knowledge of systems and the quick recall of the smallest important details necessary to excel in your career. Ask your employer if they will pay for your exam. There are eight parts to the medium and heavy truck tests – gasoline engines, diesel engines, drive train, brakes, suspension and steering, electrical and electronic systems, heating, ventilation and air conditioning (HVAC) systems, and preventative maintenance inspection.

Diesel mechanics must be physically fit as they must work and move quickly, sometimes lifting heavy machinery without the assistance of special equipment. They must have excellent recall to quickly and efficiently diagnose problems without having to consult manuals and other resources constantly. They must have great dexterity as sometimes they will need to fit tools into tight, cramped spaces. In addition, they need to be both physically and mentally flexible, using their vast knowledge to think quickly on their feet.

They sometimes have higher education but often receive all their training on-the-job. New and renewing certifications are often paid for by their employers. These professionals must have great attention to detail and understand both the technical and mechanical workings of diesel vehicles. They must also be comfortable with computer software used to diagnose and precisely repair these vehicles. Finally, customer service is a necessary skill. You want customers to continue patronizing your employer’s business, so you have to be friendly and personable. It can be frustrating for a customer when he or she has an expensive or time-consuming repair looming. A friendly, knowledgeable, trustworthy diesel mechanic will go a long way in easing their worries.

Job Description

To earn the average diesel mechanic salary you must have certain core competencies. These include complying with EPA and safety procedures as well as learning and applying cutting-edge technology to diagnose and repair the most advanced motors. You must maintain an accurate inventory of supplies and tools whether you provide those on-the-job yourself or your employer provides them for you. You must also know how to troubleshoot and repair each kind of diesel engine vehicle and perform basic preventative maintenance. If you specialize in one type of diesel vehicle, you pigeonhole yourself and lose the opportunity to advance your career.
