An auto mechanic performs maintenance work on a vehicle in order to prevent damage from occurring.  If damage does occur, the auto mechanic also diagnosis the problem and makes repairs on the vehicle.  Years ago, making repairs to a vehicle mostly involved using tools and working on the mechanics of the vehicle.  Today, auto mechanics must also be able to use computerized equipment in order to diagnose problems with the vehicle and in order to make the necessary repairs.

Auto mechanics are also called upon to perform inspections on vehicles. When performing these inspections, they must lubricate and test parts while also checking to determine if they are worn out.  In order to perform these and all other duties, the auto mechanic has to use power tools, machine tools, welding tools, and more.
