Automobile repair involves diagnosing and fixing issues in vehicles to ensure they operate safely and efficiently. This process can include routine maintenance, such as oil changes and tire rotations, as well as more complex repairs like engine overhauls or transmission replacements. Technicians, often referred to as mechanics, use specialized tools and equipment to identify problems and perform repairs. They may work in auto repair shops or dealerships, and their expertise is essential for keeping vehicles in good working condition and extending their lifespan.
