ABOUT THIS CAREER

Duties

Automotive service technicians and mechanics typically do the following:

Although service technicians work on traditional mechanical systems, such as engines, transmissions, and drivebelts, they also must be familiar with a growing number of electronic systems. Braking, transmission, and steering systems, for example, are controlled primarily by computers and electronic components.

Other integrated electronic systems, such as accident-avoidance sensors, are becoming common as well. In addition, a growing number of technicians are required to work on vehicles that use electricity or alternative fuels, such as ethanol.

Service technicians use many different tools, including computerized diagnostic tools and power tools such as pneumatic wrenches, lathes, welding torches, and jacks and hoists. These tools usually are owned by their employers.

Service technicians also use many common hand tools, such as wrenches, pliers, and sockets and ratchets. Service technicians generally own these tools themselves. In fact, experienced workers often have thousands of dollars invested in their personal tool collection. For example, some invest in their own set of pneumatic tools—such as impact wrenches—powered by compressed air.

The following are examples of types of service technicians:

Automotive air-conditioning technicians install and repair air-conditioners and parts, such as compressors, condensers, and controls. These workers must be trained and certified in handling refrigerants.

Brake technicians diagnose brake system problems, adjust brakes, replace brake rotors and pads, and make other repairs on brake systems. Some technicians specialize in both brake and front-end work. (See “Front-end technicians.”)

Drivability technicians, also known as diagnostic technicians, use their extensive knowledge of engine management and fuel, electrical, ignition, and emissions systems to diagnose issues that prevent engines from performing efficiently. They often use the onboard diagnostic system of a car and electronic testing equipment such as scan tools and multimeters to find the malfunction.

Front-end technicians diagnose ride, handling, and tire wear problems. To correct these problems, they frequently use special alignment equipment and wheel-balancing machines.

Transmission technicians and rebuilders work on gear trains, couplings, hydraulic pumps, and other parts of transmissions. An extensive knowledge of computer controls and the ability to diagnose electrical and hydraulic problems are needed to work on these complex components.

Dielsel service technicians and mechanics are technicians who work on large trucks and buses.

Heavy vehicle mobile equipment service technicians incude technicians who work on farm equipment, construction vehicles, and railcars.

Small engine mechanics include mechanics who repair and service motorcycles, motorboats, and small all-terrain vehicles.

AT A GLANCE

FAST FACTS:

What Automotive Service Technicians and Mechanics Do

Automotive service technicians and mechanics inspect, maintain, and repair cars and light trucks.

Work Environment

Most automotive service technicians and mechanics work in well-ventilated and well-lit repair shops. Although technicians often identify and fix automotive problems with computers, they commonly work with greasy parts and tools, sometimes in uncomfortable positions.

Pay

The median annual wage for automotive service technicians and mechanics was $42,090 in May 2019.
