Auto mechanic
An auto mechanic (automotive technician in most of North America, light vehicle technician in British English, and motor mechanic in Australian English) is a mechanic with a variety of automobile makes or either in a specific area or in a specific make of automobile. In repairing cars, their main role is to diagnose the problem accurately and quickly. They often have to quote prices for their customers before commencing work or after partial disassembly for inspection. Their job may involve the repair of a specific part or the replacement of one or more parts as assemblies. Basic vehicle  maintenance is a fundamental part of a mechanic's work in modern industrialized countries, while in others they are only consulted when a vehicle is already showing signs of malfunction. Preventive maintenance is also a fundamental part of a mechanic's job, but this is not possible in the case of vehicles that are not regularly maintained by a mechanic. One misunderstood aspect of preventive maintenance is "scheduled replacement" of various parts, which occurs before failure to avoid far more expensive damage. With the rapid advancement in technology, the mechanic's job has evolved from purely mechanical, to include electronic  technology. Because vehicles today possess complex computer and electronic systems, mechanics need to have a broader base of knowledge than in the past. Due to the increasingly labyrinthine nature of the technology that is now incorporated into automobiles, most automobile dealerships and independent workshops now provide sophisticated diagnostic computers to each technician, without which they would be unable to diagnose or repair a vehicle. Education. United States. In the United States, many programs and schools offer training for those interested in pursuing competencies as automotive mechanics or technicians. Areas of training include automobile repair and maintenance, collision repair, painting and  restoring, electronics, air-conditioning and heating systems, and truck and diesel mechanics. The National Automotive Technicians Education Foundation (NATEF) is responsible for evaluating technician training programs against standards developed by the automotive industry. NATEF accredits programs in four different categories: automotive, collision, trucks (diesel technology) and alternative fuels. NATEF lists secondary and post secondary schools with accredited programs on their website. Some mechanics are ASE certified, which is a standardized method of testing skill and knowledge level. While it's not required by law for a mechanic to be certified, some companies only hire or promote employees who have passed  ASE tests. The technology used in automobiles changes very rapidly and the mechanic must be prepared to learn these new technologies and systems. The auto mechanic has a physically demanding job, often exposed to extreme temperatures, lifting heavy objects and staying in uncomfortable positions for extended periods. They also may deal with exposure to toxic chemicals. The internet is being applied to the field increasingly often, with mechanics providing advice on-line. Mechanics themselves now regularly use the internet for information to help them in diagnosing and/or repairing vehicles. Paper based service manuals for vehicles have become significantly less prevalent  with computers that are connected to the Internet taking their position, giving quick access to a plethora of technical manuals and information. In addition online appointment platforms have surged allowing customers to schedule vehicle repairs by making appointments. A newer method of mobile mechanic services has emerged where the online appointment made by a person seeking repairs turns into a dispatch call and the mechanics travel to the customers location to perform the services. Related careers. A mechanic usually works from the workshop in which the (well equipped) mechanic has access to a vehicle lift to access areas that are  difficult to reach when the car is on the ground. Beside the workshop bound mechanic, there are mobile mechanics like those of the UK Automobile Association (the AA) which allow the car owner to receive assistance without the car necessarily having to be brought to a garage. A mechanic may opt to engage in other careers related to his or her field. Teaching of automotive trade courses, for example, is almost entirely carried out by qualified mechanics in many countries. There are several other trade qualifications for working on motor vehicles, including "panel beater", "spray painter", "body builder" and "motorcycle  mechanic". In most developed countries, these are separate trade courses, but a qualified tradesperson from one sphere can change to working as another. This usually requires that they work under another tradesperson in much the same way as an apprentice. Auto body repair involves less work with oily and greasy parts of vehicles, but involves exposure to particulate dust from sanding bodywork and potentially toxic chemical fumes from paint and related products. Salespeople and dealers often also need to acquire an in-depth knowledge of cars, and some mechanics are successful in these roles because of their knowledge. Auto mechanics  also need to stay updated with all the leading car companies as well as newly launched cars. Mechanics have to study continuously on new technology engines and their work systems.
