Automotive-radiator mechanics clean radiators with caustic solutions, locate and solder leaks, and install new radiator cores or replacement radiators. They also may repair heaters and air-conditioners, and solder leaks in gasoline tanks. Front-end mechanics align and balance wheels, and repair steering mechanisms and suspension systems. They frequently use special alignment equipment and wheel-balancing machines. Brake repairers adjust brakes, replace brake linings and pads, and make other repairs on brake systems.
Some mechanics specialize in both brake and front-end work.
Automotive body repairers use special equipment to restore damaged metal frames and body sections. They chain or clamp the frames and sections to alignment machines that use hydraulic pressure to align damaged components. To do so, repairers use bench systems to make accurate measurements of how much each section is out of alignment and hydraulic machinery to return the vehicle back to its original shape. Mechanics use power tools such as pneumatic wrenches to remove bolts quickly, machine tools like lathes and grinding machines to rebuild brakes, welding and flame-cutting equipment to remove and repair exhaust systems, and jacks and hoists to lift cars and engines. They also use common hand tools like screwdrivers, pliers, and wrenches.
