Diesel mechanics repair and maintain large trucks, tractors and buses. Courses in diesel technology or mechanics are generally found as part of certificate, career diploma or associate's degree programs available at technical institutes and community colleges. Some schools offer a hybrid format.
Although no set education requirements exist for employment as a diesel mechanic, employers often prefer candidates with formal training. National certification is available through the National Institute for Automotive Service Excellence (ASE) and may increase employment opportunities. Completion of diesel mechanic training may lead to a career as a diesel service technician, diesel engine specialist or truck mechanic.
Vehicle maintenance tools are necessary for students to gain hands-on mechanical practice, and they may need to be purchased separately.
