Mechanics work to diagnose, troubleshoot, and fix vehicle malfunctions through a series of visual and diagnostic testing, test drives, and other methods. A mechanic is responsible for performing routine maintenance such as oil changes, tire rotations, structural work, and repairs from auto accidents. They must speak to customers about their automobiles’ performance and history, inspect mechanical components, and prepare repair cost estimates. The mechanic establishes repair work timelines, and discusses options with customers. They must be mechanically minded and proficient in using diagnostic equipment, hand tools, and other necessary equipment. Mechanics often work in car dealerships, repair shops, service centers, or other auto body settings.
