Owing to the durability and efficiency of diesel engines, they are increasingly being used in trucks, buses, other heavy vehicles, commercial boats, and bulldozers and cranes. Diesel mechanics are primarily responsible for inspecting, repairing, and overhauling vehicles that have a diesel engine.
Over time, maintenance and service of diesel engines has become more complex since operations like fuel injection and engine timing systems are now mechanized and computerized to a great extent. Diesel mechanics may be involved in:
-
Working on vehicle's electrical system
-
Major engine repairs
-
Monitoring emission control systems so that they comply with pollution regulations.
Although many diesel technicians and mechanics receive informal on the job training, it could be a good idea for you to complete postsecondary education and receive industry certifications. There are many diesel mechanic schools in which you could enroll. Programs are usually offered at community colleges and trade and vocational schools. If you want to save money and keep your current job, you may want to consider getting into an online diesel mechanic school. You'll enjoy the comfort and convenience of studying from home according to your own study schedule.
Program Curriculum
You will acquire training in areas like automotive repair, electronics, and mathematics. To help ensure that students gain hands-on knowledge, program curriculums are designed to incorporate practical exercises too. You will learn about engine repair techniques, equipment, and diesel technology. Students gain knowledge in areas like electronic circuits, steering and drive trains, cooling systems, truck brake systems, and converters. Some courses that you may come across include:
-
Diesel Electrical and Electronic Systems
-
Introduction to Diesel Tools, Technology and Safety
-
Preventative Medicine

Certification
Although not a requirement, acquiring a certification could further enhance your knowledge and job prospects, showing to potential employers that you are committed to the field. Diesel mechanics may obtain certifications through the National Institute for Automotive Service Excellence. In order to be eligible for the certification, you'll need to have two years of work experience and pass an ASE exam. The certificate needs to be renewed after every five years.
