Diesel engines run differently than normal gas engines, so, naturally, they require a different set of skills to maintain them. Diesel mechanics are the specialists who maintain diesel engines in cars, light trucks, semi-trucks, and more. You also have the opportunity to further specialize in the types and sizes of engines you work on.
Read on to learn more about becoming a diesel engine specialist and what careers you could have in the industry, or find your ideal mechanic training program now.
On the Job | What You’ll Do
In 2023, diesel mechanics earned an average of $59,920 (bls.gov). The top 10 percentage of diesel engine specialists made $82,430 or more.
As a diesel mechanic, you can work on light, medium, or heavy-duty equipment. Light vehicles are diesel cars and heavy duty pickups, whereas medium and heavy-duty vehicles are school buses, semis, and construction equipment.
You’ll be responsible for the upkeep and repair for all diesel vehicle systems—brakes, electrical, drive train, and more — just as mechanics do with gas-fueled cars.
On the job, you’ll:
- Run tests
- Diagnose problems
- Replace parts
- Test equipment
- Communicate with vehicle owners
You can be hired at dealerships, auto shops, or a company with a fleet and a garage. Eventually, once you have the space and tools, you could work for yourself. Many diesel mechanics, if they are entrepreneurial as well, look forward to opening their own performance shop.
Job Training and Certification
A lot of mechanical knowledge can be picked up outside of a training program, but it’s important to go through a class, especially if you’re seeking ASE certification. In many cases, employers look for formal training among applicants. Training helps set you apart from the others, and it can help command a higher pay rate.
After you’re done with a training program and meet the necessary work experience as a diesel mechanic, you’ll want to pursue your ASE certifications from the National Institute for Automotive Service Excellence.
Becoming ASE certified is one of the best ways to increase your pay and work responsibilities throughout your career.
Diesel mechanics can become ASE master certified by taking tests T2-T8:
- T2 – Diesel Engines
- T3 – Drive Train
- T4 – Brakes
- T5 – Suspension & Steering
- T6 – Electrical/Electronic Systems
- T7 – Heating, Ventilation & Air Conditioning
- T8 – Preventive Maintenance Inspection
These skill assessment tests are the automotive industry’s gold standard, and your training program will prepare you for these.
Diesel Mechanic Demand
If you're someone who enjoys working on engines, you’ll be making a great career choice by choosing to become a diesel mechanic.
The Bureau of Labor Statistics expects that demand for diesel mechanics will remain relatively steady between now and 2032. The BLS predicts that over the next decade, there will be about 24,300 job openings for diesel service technicians.
Diesel mechanics are essential for keeping semi trucks on the road and construction equipment moving. Between heavy-duty equipment and passenger vehicles, a diesel mechanic's job is never dull. With something new to work on each day, you can have a rewarding career where your work and passion coincide.
