Nature of the Work

Automotive service technicians inspect, maintain, and repair automobiles and light trucks that run on gasoline, diesel, or alternative fuels such as ethanol. They perform basic care maintenance, diagnose problems, and plan and execute vehicle repairs. The responsibilities of automotive service technicians and mechanics have evolved from simple mechanical repairs to high-level technology-related work. Today, integrated electronic systems and complex computers regulate vehicles and their performance while on the road. This increasing sophistication of automobiles requires workers to use computerized shop equipment and work with electronic components while maintaining their skills with traditional hand tools. Technicians must have a broad knowledge of how vehicles' complex components work and interact.

To locate problems, technicians use a diagnostic approach. They first test to see whether components and systems are secure and working properly. They then isolate the components or systems that might be the cause of the problems. Service technicians use a variety of tools in their work. They use pneumatic wrenches and other power tools 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.
