Anyone whose car or light truck has broken down knows the importance of the jobs of automotive service technicians and mechanics. The ability to diagnose the source of a problem quickly and accurately requires good reasoning ability and a thorough knowledge of automobiles. Many technicians consider diagnosing hard-to-find troubles one of their most challenging and satisfying duties.
The work of automotive service technicians and mechanics has evolved from mechanical repair to a high technology job. As a result, these workers are now usually called “technicians” in automotive services and the term “mechanic” is falling into disuse. Today, integrated electronic systems and complex computers run vehicles and measure their performance while on the road. Technicians must have an increasingly broad base of knowledge about how vehicles’ complex components work and interact, as well as the ability to work with electronic diagnostic equipment and computer-based technical reference materials.
Automotive service technicians use their high-tech skills to inspect, maintain, and repair automobiles and light trucks that run on gasoline, ethanol and other alternative fuels, such as electricity. The increasing sophistication of automotive technology now requires workers who can use computerized shop equipment and work with electronic components while maintaining their skills with traditional hand tools. (Service technicians who work on diesel-powered trucks, buses, and equipment are discussed in the Handbook section on diesel service technicians and mechanics. Motorcycle technicianswho repair and service motorcycles, motor scooters, mopeds, and, occasionally, small all-terrain vehiclesare discussed in the Handbook section on small engine mechanics.)
When mechanical or electrical troubles occur, technicians first get a description of the symptoms from the owner or, if they work in a large shop, from the repair service estimator or service advisor who wrote the repair order. To locate the problem, technicians use a diagnostic approach. First, they test to see whether components and systems are proper and secure. Then, they isolate the components or systems that could not logically be the cause of the problem. For example, if an air-conditioner malfunctions, the technician’s diagnostic approach can pinpoint a problem as simple as a low coolant level or as complex as a bad drive-train connection that has shorted out the air conditioner. Technicians may have to test drive the 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 may indicate whether a component is salvageable or whether a new one is required to get the vehicle back in working order.
During routine service inspections, technicians test and lubricate engines and other major components. In some cases, the technician may repair or replace worn parts before they cause breakdowns that could damage critical components of the vehicle. Technicians usually follow a checklist to ensure that they examine every critical part. Belts, hoses, plugs, brake and fuel systems, and other potentially troublesome items are among those closely watched.
Service technicians use a variety of tools in their workpower tools, such as pneumatic wrenches to remove bolts quickly; machine tools like lathes and grinding machines to rebuild brakes; welding and flame-cutting equipment to remove and repair exhaust systems, and jacks and hoists to lift cars and engines. They also use common hand tools, such as screwdrivers, pliers, and wrenches, to work on small parts and in hard-to-reach places.
Computers also have become commonplace in modern repair shops. Service technicians compare the readouts from computerized diagnostic testing devices with the benchmarked standards given by the manufacturer of the components being tested. Deviations outside of acceptable levels are an indication to the technician that further attention to an area is necessary. A shop’s computerized system provides automatic updates to technical manuals and unlimited access to manufacturers’ service information, technical service bulletins, and other databases that allow technicians to keep current on problem spots and to learn new procedures.
Automotive service technicians in large shops have increasingly become specialized. For example, transmission technicians and rebuilders work on gear trains, couplings, hydraulic pumps, and other parts of transmissions. Extensive knowledge of computer controls, the ability to diagnose electrical and hydraulic problems, and other specialized skills are needed to work on these complex components, which employ some of the most sophisticated technology used in vehicles. Tuneup technicians adjust the ignition timing and valves, and adjust or replace spark plugs and other parts to ensure efficient engine performance. They often use electronic testing equipment to isolate and adjust malfunctions in fuel, ignition, and emissions control systems.
Automotive air-conditioning repairers install and repair air-conditioners and service their components, such as compressors, condensers, and controls. These workers require special training in Federal and State regulations governing the handling and disposal of refrigerants. Front-end mechanics align and balance wheels and repair steering mechanisms and suspension systems. They frequently use special alignment equipment and wheel-balancing machines. Brake repairers adjust brakes, replace brake linings and pads, and make other repairs on brake systems. Some technicians specialize in both brake and front-end work. Even though electronics and electronic systems in automobiles were a specialty in the past, electronics are now so common that it is essential for all types of service technicians to be familiar with at least the basic principles of electronics.
Nearly half of automotive service technicians work more than 40 hours a week. Some may also work evenings and weekends to satisfy customer service needs. Generally, service technicians work indoors in well-ventilated and -lighted repair shops. However, some shops are drafty and noisy. Although some problems can be fixed with simple computerized adjustments, technicians frequently work with dirty and greasy parts, and in awkward positions. They often lift heavy parts and tools. Minor cuts, burns, and bruises are common, but technicians can usually avoid serious accidents if the shop is kept clean and orderly, and safety practices are observed.
Automotive technology is rapidly increasing in sophistication, and most training authorities strongly recommend that persons seeking automotive service technician and mechanic jobs complete a formal training program in high school, or in a postsecondary vocational school or community college. However, some service technicians still learn the trade solely by assisting and learning from experienced workers. Courses in automotive repair, electronics, physics, chemistry, English, computers, and mathematics provide a good educational background for a career as a service technician.
High school programs, while an asset, vary greatly in scope. Some aim to equip graduates with enough skills to get a job as a technician’s helper or trainee technician. Other programs offer only an introduction to automotive technology and service for the future consumer or hobbyist. Some of the more extensive programs participate in Automotive Youth Education Service (AYES), which has about 500 participating schools and more than 4000 participating dealers. Students who complete these programs receive an AYES certification and upon high school graduation are better prepared to enter entry-level technician positions, or to advance their technical education.
Postsecondary automotive technician training programs vary greatly in format, but normally provide intensive career preparation through a combination of classroom instruction and hands-on practice. Some trade and technical school programs provide concentrated training for 6 months to a year, depending on how many hours the student attends each week, and award a certificate. Community college programs normally award an associate degree or certificate and usually spread the training over 2 years by supplementing the automotive training with instruction in English, basic mathematics, computers, and other subjects. Some students earn repair certificates in one particular skill and opt to leave the program to begin their career before graduation. Recently, some programs have added to their curriculums training on employability skills such as customer service and stress management. Employers find that these skills help technicians handle the additional responsibilities of dealing with the customers and parts vendors.
The various automobile manufacturers and their participating dealers sponsor 2-year associate degree programs at postsecondary schools across the Nation. The Accrediting Commission of Career Schools and Colleges of Technology (ACCSCT) currently certifies a number of automotive and diesel technology schools. Schools update their curriculums frequently to reflect changing technology and equipment. Students in these programs typically spend alternate 6- to 12-week periods attending classes full time and working full time in the service departments of sponsoring dealers. At these dealerships, students get practical experience while assigned to an experienced worker who provides hands-on instruction and timesaving tips.
The ASE certification is a nationally recognized standard for programs offered by high schools, postsecondary trade schools, technical institutes, and community colleges that train automobile service technicians. Some automotive manufacturers provide ASE-certified instruction programs with service equipment and current-model cars on which students practice new skills and learn the latest automotive technology. While ASE certification is voluntary, it does signify that the program meets uniform standards for instructional facilities, equipment, staff credentials, and curriculum. To ensure that programs keep up with ever-changing technology, repair techniques, and ASE standards, the certified programs are subjected to periodic compliance reviews and mandatory recertification, as are the ASE standards themselves. In 2004, about 2000 high school and postsecondary automotive service technician training programs had been certified by ASE.
For trainee automotive service technician jobs, employers look for people with strong communication and analytical skills. Technicians need good reading, mathematics, and computer skills to study technical manuals and to keep abreast of new technology and learn new service and repair procedures and specifications. Trainees also must possess mechanical aptitude and knowledge of how automobiles work. Most employers regard the successful completion of a vocational training program in automotive service technology as the best preparation for trainee positions. Experience working on motor vehicles in the Armed Forces or as a hobby also is valuable. Because of the complexity of new vehicles, a growing number of employers require completion of high school and additional postsecondary training.
Many new cars have several onboard computers, operating everything from the engine to the radio. Engine controls and dashboard instruments were among the first components to use electronics, but today most automotive systems, such as braking, transmission, and steering systems, are controlled primarily by computers and electronic components. Some of the more advanced vehicles have global positioning systems, Internet access, and other high-tech features integrated into the functions of the vehicle. The training in electronics is vital because electrical components, or a series of related components, account for nearly all malfunctions in modern vehicles.
In addition to electronics and computers, automotive service technicians will have to learn and understand the science behind the alternate-fuel vehicles that have begun to enter the market. The fuel for these vehicles will come from the dehydrogenization of water, electric fuel cells, natural gas, solar power, and other non-petroleum-based sources. Hybrid vehicles, for example, use the energy from braking to recharge batteries that power an electric motor, which supplements a gasoline engine. As vehicles with these new technologies become more common, technicians will need additional training to learn the science and engineering that makes them possible. Currently, the manufacturers of these alternate-fuel vehicles are providing the necessary training. However, as the warrantees begin to expire, technicians in all industries will need to be trained to service these vehicles. As the number of these automobiles on the road increases, some technicians will likely specialize in the service and repair of these vehicles.
Those new to automotive service usually start as trainee technicians, technicians’ helpers, or lubrication workers, and gradually acquire and practice their skills by working with experienced mechanics and technicians. With a few months’ experience, beginners perform many routine service tasks and make simple repairs. While some graduates of postsecondary automotive training programs are often able to earn promotion to the journey level after only a few months on the job, it typically takes 2 to 5 years of experience to become a journey level service technician, who is expected to quickly perform the more difficult types of routine service and repairs. An additional 1 to 2 years of experience familiarizes technicians with all types of repairs. Complex specialties, such as transmission repair, require another year or two of training and experience. In contrast, brake specialists may learn their jobs in considerably less time because they do not need a complete knowledge of automotive repair.
At work, the most important possessions of technicians are their hand tools. Technicians usually provide their own tools, and many experienced workers have thousands of dollars invested in them. Employers typically furnish expensive power tools, engine analyzers, and other diagnostic equipment, but technicians accumulate hand tools with experience. Some formal training programs have alliances with tool manufacturers that help entry-level technicians accumulate tools during their training period.
Employers increasingly send experienced automotive service technicians to manufacturer training centers to learn to repair new models or to receive special training in the repair of components, such as electronic fuel injection or air-conditioners. Motor vehicle dealers and other automotive service providers also may send promising beginners to manufacturer-sponsored technician training programs; most employers periodically send experienced technicians to manufacturer-sponsored technician training programs for additional training to maintain or upgrade employees’ skills and thus increase the employees’ value to the employer. Factory representatives also visit many shops to conduct short training sessions.
Voluntary certification by the National Institute for Automotive Service Excellence (ASE) has become a standard credential for automotive service technicians. Certification is available in 1 or more of 8 different areas of automotive service, such as electrical systems, engine repair, brake systems, suspension and steering, and heating and air-conditioning. For certification in each area, technicians must have at least 2 years of experience and pass the examination. Completion of an automotive training program in high school, vocational or trade school, or community or junior college may be substituted for 1 year of experience. For ASE certification as a master automobile technician, technicians must be certified in all eight areas. Technicians must retake each examination once every 5 years to maintain their certifications.
Experienced technicians who have leadership ability sometimes advance to shop supervisor or service manager. Those who work well with customers may become automotive repair service estimators. Some with sufficient funds open independent repair shops.
Automotive service technicians and mechanics held about 803,000 jobs in 2004. The majority worked for automotive repair and maintenance shops, automobile dealers, and retailers and wholesalers of automotive parts, accessories, and supplies. Others found employment in gasoline stations; home and auto supply stores; automotive equipment rental and leasing companies; Federal, State, and local governments; and other organizations. More than 16 percent of service technicians were self-employed, more than twice the proportion for all installation, maintenance, and repair occupations.
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 as employers report difficulty in finding workers with the right skills. Persons with good diagnostic and problem-solving abilities, and whose training includes basic electronics and computer courses, should have the best opportunities. For well-prepared people with a technical background, automotive service technician careers offer an excellent opportunity for good pay and the satisfaction of highly skilled work with vehicles incorporating the latest in advanced technology. However, persons without formal automotive training are likely to face competition for entry-level jobs.
Employment of automotive service technicians and mechanics is expected to increase as fast as the average through the year 2014. Over the 2004-14 period, demand for technicians will grow as the number of vehicles in operation increases, reflecting continued growth in the number of multi-car families. Growth in demand will be offset somewhat by slowing population growth and the continuing increase in the quality and durability of automobiles, which will require less frequent service. 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. While car owners may postpone maintenance and repair on their vehicles when their budgets become strained, and employers of automotive technicians may cutback hiring new workers, changes in economic conditions generally have minor effects on the automotive service and repair business.
Employment growth will continue to be concentrated in automobile dealerships and independent automotive repair shops. Many new jobs also will be created in small retail operations that offer after-warranty repairs, such as oil changes, brake repair, air-conditioner service, and other minor repairs generally taking less than 4 hours to complete. Employment of automotive service technicians and mechanics in gasoline service stations will continue to decline, as fewer stations offer repair services.
Median hourly earnings of automotive service technicians and mechanics, including commission, were $15.60 in May 2004. The middle 50 percent earned between $11.31 and $20.75 per hour. The lowest 10 percent earned less than $8.70, and the highest 10 percent earned more than $26.22 per hour. Median annual earnings in the industries employing the largest numbers of service technicians in May 2004 were as follows:
Automotive repair and maintenance
Automotive parts, accessories, and tire stores
Many experienced technicians employed by automobile dealers and independent repair shops receive a commission related to the labor cost charged to the customer. Under this method, weekly earnings depend on the amount of work completed. Employers frequently guarantee commissioned technicians a minimum weekly salary.
Some automotive service technicians are members of labor unions such as the International Association of Machinists and Aerospace Workers; the International Union, United Automobile, Aerospace and Agricultural Implement Workers of America; the Sheet Metal Workers’ International Association; and the International Brotherhood of Teamsters.
