Auto mechanics work on a wide range of vehicles, from small passenger cars to motorcycles to diesel trucks and buses, performing maintenance and repairs. Many mechanics specialize in particular areas of repair, such as engine work, auto body work, and electronic systems. There are a variety of auto mechanic jobs available because there is so much room for specialization.
Many auto mechanics work as part of a team of service technicians in independent shops. Preventative maintenance, such as replenishing various fluids, changing filters, rotating tires, and diagnosing engines, is frequently performed general mechanics. They may use troubleshooting guidelines to diagnose problems and repair or replace damaged parts when an automobile is not running properly.
Auto mechanic jobs frequently necessitate a thorough understanding of a specific aspect of vehicles. Transmission mechanics, for example, specialize in gears, drive shafts, bearings, and casings, among other components of automatic and manual transmission systems. Brake specialists diagnose brake system issues, replenish brake fluids, and replace brake pads. Mechanics may also specialize in servicing complex electrical systems, which vary widely between vehicle types. Front end repair, bodywork, and ignition system maintenance are examples of other specialties.
Diesel mechanics work on passenger cars, commercial trucks, and buses with diesel engines. Diesel-powered vehicles operate differently than gasoline-powered vehicles, and they often necessitate very different maintenance and repair procedures. Diesel mechanics, like other auto mechanics, often specialize in transmission repair, brake repair, computer systems, or other areas. They may work for small repair shops or companies with a large fleet of diesel vehicles that require routine maintenance.
To work as an auto mechanic in any specialty, a person typically needs a high school diploma and previous repair experience. Many employers prefer to hire mechanics who have completed vocational school or community college training programs. Though specific certification is not always required, many beginning mechanics take a test offered a nationally recognized institution to improve their credentials and increase their chances of finding auto mechanic jobs. The National Institute for Automotive Service Excellence in the United States offers certification in a variety of areas, including brake repair, air conditioning and heating, and electronic systems.
The number of different auto mechanic jobs continues to grow as automotive technology advances and alternative fuel vehicles become more popular. Computer and electronic system specialists are in high demand to maintain the complex systems found in many modern vehicles. Electric, hydrogen, and biofuel vehicles necessitate the expertise of highly specialized maintenance and repair mechanics.
