Diesel Mechanics

Experience is gained during training programs or postsecondary education to earn an associate's degree, and through internships and on-the-job training.

Diesel mechanics must be patient and thorough, have excellent troubleshooting skills to deduce the cause of system malfunctions, be detail oriented, have excellent manual dexterity, and be willing to continue to learn throughout their careers. They also need to be in good shape and possess physical strength because they often have to work in tight spaces and lift heavy parts and tools, such as exhaust system components. Other important traits include patience and good organizational and time-management skills.
