Diesel Mechanic Schools in California

Diesel service mechanics are trained to inspect and repair vehicles with diesel engines. This career can be ideal for people who have strong customer service, mechanical, technical and problem-solving skills. Those who have a steady hand and enjoy math and computers also make excellent diesel service technicians. These type of mechanics are often responsible for inspecting equipment and materials in order to identify the cause of defect or error. They may also analyze data and information to determine the best solution for a mechanical problem. They must be knowledgeable about machines, tools, equipment, and transportation policies and regulations.

While some diesel mechanics may learn the trade from on-the-job training, many jobs in this field require a minimum of a high school diploma for employment. In recent years, an increasing number of employers prefer candidates with postsecondary training in the field. There are a large number of diesel mechanic schools in California that can prepare students for a career as a diesel mechanic.

According to national findings reported by the Bureau of Labor Statistics (BLS) in 2010, the majority of diesel mechanics worked for private companies, and 11 percent worked for the government. Approximately 18 percent of all diesel mechanics belonged to a union. Potential jobs include specializing in general freight trucking, automotive repair and maintenance, motor vehicle and parts wholesalers, and specialized freight trucking. According to the BLS, as of May 2011, California has the second-highest employment levels for diesel engine specialists (along with bus and truck mechanics).

Certification is not required for employment as a diesel mechanic, but may be preferred by many employers and can often increase chances of employment. Additionally, earning certification communicates education, experience and expertise to potential clients. The National Institute for Automotive Service Excellence (ASE), the nationally recognized institution that certifies automotive professionals, requires certification candidates to pass an exam and have two years work experience. ASE offers exam prep and training, including free study guides and webinars, and testing for those interested in earning a credential in the industry, including diesel mechanic certification. The certification test consists of 45 questions and tests knowledge about electronic diesel engine controls, the diagnosis of diesel engines and diesel fuel systems. Once certification is achieved, diesel mechanics must retake the exam every five years to keep the credential current.
