Here’s a brief list of what Diesel Technicians do:

• Diagnostic Testing: Using diagnostic tools and equipment to identify mechanical, electrical, and hydraulic issues in diesel engines and systems.

• Engine Repair and Overhaul: Performing repairs, overhauls, and rebuilds of diesel engines, including cylinder head repairs, piston replacements, and valve adjustments.

• Fuel System Maintenance: Inspecting, cleaning, repairing, and replacing components of diesel fuel systems, including fuel injectors, pumps, filters, and lines.

• Exhaust System Maintenance: Inspecting and repairing exhaust systems, including diesel particulate filters (DPF), exhaust gas recirculation (EGR) systems, and mufflers.

• Air Intake System Service: Cleaning and repairing air intake systems, including air filters, turbochargers, intercoolers, and intake manifolds.

• Cooling System Service: Checking and maintaining cooling systems, including radiators, water pumps, hoses, and thermostats to prevent overheating.

• Electrical System Work: Diagnosing and repairing electrical issues in diesel vehicles, including batteries, starters, alternators, and wiring harnesses.

Here’s how YOU can become one:

1. High School Education:

• Earn a high school diploma or equivalent. Focus on courses in mathematics, science (especially physics), and technical education. Developing strong problem-solving skills and mechanical aptitude early on can be beneficial.

2. Post-Secondary Education:

• Consider enrolling in a vocational or technical school that offers programs specifically in diesel technology or diesel mechanics. Look for programs that provide hands-on training and cover topics such as diesel engines, fuel systems, electrical systems, hydraulics, and diagnostics.

• Some community colleges and technical institutes offer associate degree programs in diesel technology, which provide a more comprehensive education and may include general education courses.

3. Apprenticeship or Entry-Level Position:

• Gain practical experience through an apprenticeship or entry-level position at a repair shop, dealership, fleet maintenance facility, or equipment rental company.

• Apprenticeships typically combine on-the-job training with classroom instruction under the guidance of experienced diesel mechanics.

4. Certification:

• Consider obtaining certification from the National Institute for Automotive Service Excellence (ASE) in diesel technology. ASE certification demonstrates your competence and proficiency in diesel engine repair and maintenance.

• ASE offers certification exams in various areas of diesel technology, including diesel engines, electronic systems, heating and air conditioning, and more.

5. Gain Experience and Specialize:

• As you gain experience, specialize in specific types of diesel engines or vehicles, such as heavy-duty trucks, construction equipment, agricultural machinery, or marine engines.

• Stay updated with advancements in diesel engine technology through manufacturer training programs, continuing education courses, and workshops.

6. Skills Development:

• Develop strong diagnostic skills to identify and troubleshoot problems in diesel engines and related systems.

• Familiarize yourself with diesel engine components, including fuel injection systems, turbochargers, exhaust systems, and emissions controls.

• Improve your proficiency in using specialized tools and diagnostic equipment for diesel engine repair and maintenance.

7. Licensing Requirements:

• Depending on your location, you may need to obtain a state or provincial license or certification to work as a diesel mechanic. Check with your local regulatory body for specific requirements.
