About AUTO MECHANICS

Auto Mechanics (also known as Automobile Technology) is a technical and vocational subject that deals with the maintenance, repair, and servicing of motor vehicles. It involves understanding how different vehicle systems work — such as the engine, brakes, transmission, electrical system, and more — and how to diagnose and fix faults.

The subject equips students with practical skills in vehicle inspection, engine repair, parts replacement, lubrication, diagnostics, and safe workshop practices. It prepares learners for careers as auto technicians, mechanics, vehicle inspectors, and garage operators, and also supports entrepreneurship in the auto industry.
