Some mechanics specialize in both brake and front-end work. Automotive-radiator mechanics clean radiators with caustic solutions, locate and solder leaks, and install new radiator cores or complete replacement radiators. They also may repair heaters and air-conditioners, and solder leaks in gasoline tanks. The ability to diagnose mechanical and electrical problems quickly is one of the mechanic's most valuable skills. Generally, mechanics work indoors.
Most repair shops are well ventilated and lighted, but some are drafty and noisy.
Mechanics frequently work with dirty and greasy parts, and in awkward positions. They often must lift heavy parts and tools. Minor cuts, burns, and bruises are common, but serious accidents are avoided when the shop is kept clean and orderly and safety practices are observed. Employment Automotive mechanics held about 739,000 jobs in 1992. The majority worked for retail and wholesale automotive dealers, independent automotive repair shops, and gasoline service stations.
