Detailed Guide for

Automotive Service Technicians and Mechanics in California

May also be called: Auto Technicians; Auto Brake Mechanics; Fuel Injection Servicers; and Auto Transmission Specialists

Specialties within this occupation include: Automotive Air-Conditioning Repairers; Brake Repairers; Undercar Technicians; Transmission Technicians; and Engine Performance Technicians

What Would I Do?

Automotive Service Technicians inspect, repair, and maintain automobiles and other gasoline, diesel, or alternate-fueled vehicles. In smaller shops, Technicians complete a wide variety of repairs from simple engine tune-ups to tearing down, repairing, and rebuilding of complete power systems. They also service and repair electrical systems; align and service suspension, braking, and steering systems; repair and service air conditioning, heating, and engine-cooling systems. In larger shops, some of this work is completed by specially-trained Technicians who are assigned by their specialty area, such as brake repairers, undercar or transmission mechanics.

To diagnose an automotive malfunction, Technicians may need to test drive a vehicle or use a variety of testing equipment, such as onboard and hand-held diagnostic computers or compression gauges to identify the source of the problem. These tests indicate whether a part is salvageable or whether a new part is needed to repair the vehicle.

Today’s automobiles are run by complex computers and integrated electronic systems. The work of Automotive Service Technicians has progressed from mechanical repair into a high-technology job. The advances in automotive technology create a need for workers who can use computerized shop equipment and work with electronic components while maintaining their skills with traditional hand tools.

Automotive Air-Conditioning Repairers install and repair air-conditioners and service their components, such as compressors, condensers, and controls. They complete special training concerning the handling and disposal of refrigerants to comply with federal and State regulations.

Brake Repairers adjust brakes, replace brake linings and pads, and make other repairs on brake systems. They also diagnose and repair computer controlled anti-lock brake systems and traction control.

Undercar Specialists align and balance wheels and repair steering mechanisms and suspension systems.

Transmission Technicians work on gear trains, couplings, hydraulic pumps, and other parts of transmissions. Transmissions are very complex components that involve some of the most sophisticated technology used in vehicles.

Engine Performance Technicians service emission control systems and adjust valves or replace spark plugs and other parts to ensure efficient engine performance and the proper operation of emission control systems.

Working Conditions

Automotive Service Technicians usually work indoors in well-ventilated and lighted repair shops. However, some shops are drafty and noisy. They work with dirty and greasy parts and in awkward positions. Automotive Technicians risk injury from lifting heavy parts and tools. Minor cuts, burns, and bruises are common but the risk of injury is reduced if the shop is kept in an orderly condition where safety practices are observed.

Many Automotive Service Technicians work more than 40 hours a week. Some may also work evenings and weekends to meet customer needs.

Most Technicians must provide their own tools, which can be very expensive. Technicians have often invested thousands of dollars in their tools by the time they reach journey level. Employers usually supply the more expensive power tools, engine analyzers, and other diagnostic equipment.

Some Automotive Service Technicians are members of labor unions such as the International Association of Machinists and Aerospace Workers, the Sheet Metal Workers’ International Association, and the International Brotherhood of Teamsters.

Will This Job Fit Me?

The job of Automotive Service Technician may appeal to those who enjoy activities that involve practical, hands-on problems and solutions. Automotive Technicians occupations satisfy those with realistic interests. Realistic occupations involve technical or mechanical activities.

What Wages and Benefits Can I Expect?

Automotive Service Technicians may expect to receive benefits that include health insurance, retirement plans, paid holidays, and vacation.

What is the Job Outlook?

The need for Automotive Service Technicians will remain very strong as the number of vehicles in operation increases, reflecting the continued growth in the number of multi-car families. Job opportunities in this occupation are expected to be very good for persons who complete automotive training programs in high school, vocational and technical schools, or community colleges. Persons with good diagnostic and problem-solving abilities, and whose training includes basic electronics and computer courses, should have the best opportunities. However, persons without formal automotive training are likely to face competition for entry-level jobs. Additional job openings will be due to the need to replace a growing number of retiring technicians, who tend to be the most experienced workers.
Most persons who enter the occupation can expect steady work, even through downturns in the economy.

Employment growth will continue to be concentrated in automobile dealerships and independent automotive repair shops. Employment of automotive service technicians and mechanics in gasoline service stations will continue to decline, as fewer stations offer repair services.

Projections of Employment

In California, the number of Automotive Service Technicians and Mechanics is expected to decline between 2018 and 2028.

How Do I Qualify?

Education, Training, and Other Requirements

Due to the complexity of today’s automotive technology, most employers prefer to hire employees with a high school diploma who have completed a postsecondary vocational or community college automotive technician training program. Applicants must be physically able to perform all phases of the work and have the ability to distinguish color differences. Many employers also require a valid California driver license because Automotive Technicians often test drive vehicles to diagnose mechanical problems.


The amount and type of work experience required varies from company to company. However, Automotive Service Technicians’ apprenticeship programs usually require 8,000 work hours and completion of 144 hours a year of technical classroom instruction. Instruction is available at various California community colleges.

Early Career Planning

High school students interested in Automotive Technician careers should take courses in English, mathematics, computer technology, electronics, physics, and auto and machine shop. Technicians need good reading, mathematics, and computer skills to study technical manuals and to keep abreast of new technology and learn new repair procedures.

Apprenticeship and Work Study Programs

Apprentices learn their trade while working on the job. They also attend evening classes for technical instruction. Many apprenticeship programs require a high school diploma or equivalent. For more information on apprenticeship programs currently available, visit the State of California's Department of Industrial Relations, Division of Apprenticeship Standards Web site.

Training programs for Automotive Technicians are also available through Regional Occupational Programs. Applicants in the program must be physically able to complete all stages of automotive work. Also, they must be a minimum of 18 years old or 17 years old with parental consent. To find an ROP program near you, go to the California Association of Regional Occupational Centers and Programs Web site.

Continuing Education

It is very important for Automotive Service Technicians to keep up to date with the latest developments in automotive technology. They must retest every five years to obtain the National Institute for Automotive Service Excellence recertification.

Licensing and Certification

Technicians working as Brake/Lamp Adjusters or Smog Check Technicians must be licensed through the California Department of Consumer Affairs. The Brake/Lamp Adjuster license is valid for four years and the Smog Check Technician license is valid for two years.
