If you've ever been curious about engines — how they work, how to fix them, how to make them run better — consider a career as a diesel mechanic.
Diesel mechanics work with their hands, solve dynamic problems and maintain diesel-fueled vehicles that help keep industries moving.
But it’s not just about knowing your way around a wrench. Diesel engines power some of the biggest machines on the road and at job sites, and getting certified can help prove that your skills meet industry standards.
Let’s break down what it takes to get certified and how Universal Technical Institute’s 48-week Diesel Technology program can help you prepare to get there.1,7
What Does a Diesel Mechanic Do?
A diesel mechanic inspects, diagnoses, repairs and maintains diesel systems. These systems and engines are used in everything from buses and trucks to generators and heavy equipment. Their size and complexity require specialized knowledge and a strong foundation in the systems that make them run — fuel, air intake, exhaust, electrical and more.
In this role, you could handle engine rebuilds, inspect drivetrains, test emissions systems or troubleshoot electrical faults. The work is hands-on and needed in industries like transportation, construction and agriculture.

What Are the Requirements for Becoming a Diesel Mechanic?
Most employers want entry-level technicians who are qualified for the role. That’s why many aspiring diesel mechanics start with a core training program like UTI’s Diesel Technology program. In less than a year, students get to train with industry-aligned tools and technology, learning the skills needed to become qualified diesel pros after graduating.
But success also depends on more than technical skill. Diesel techs need to think on their feet, communicate clearly and pay close attention to detail. The ability to explain what’s wrong with a system — and how to fix it — is part of the job.
What Is ASE Certification for Diesel Mechanics?
ASE (National Institute for Automotive Service Excellence) certification is one of the most widely recognized credentials for vehicle technicians, including diesel technicians. Becoming an ASE-certified diesel mechanic helps show that you’ve met national industry standards.
There are several ASE test areas specific to diesel mechanics, including diesel engines, drive train systems, brakes and electrical/electronic systems. Technicians must pass these exams and meet work experience requirements to earn certification.

How Can I Get ASE Certification?
To take an ASE exam, you’ll need two years of hands-on work experience. Fortunately, the Diesel Technology program at UTI is accredited by the ASE Education Foundation, which means the diesel mechanic courses in the curriculum are built to help prepare you for ASE testing. Graduates of UTI’s diesel mechanic program can also substitute their training for one of those two years of experience required for testing.
That means you can be double-focused, also using your hands-on training as certification prep.18 You can learn how to apply technical knowledge to real repairs and avoid walking into exams cold.
