Auto repair is the process of diagnosing, servicing, and repairing a vehicle in order to restore it to its original condition. This may include inspecting, replacing, or repairing parts such as brakes, engines, exhaust systems, transmission systems, and other components. Auto repair technicians use specialized tools and diagnostic equipment to identify problems with a car’s systems and then make repairs accordingly. They also provide preventive maintenance services such as oil changes and tune-ups. In addition to these services, auto repair shops can offer additional services such as detailing and customizing vehicles.
