What Are the Business Scopes of Category III Auto Maintenance?
3 Answers
Category III auto maintenance scopes include: automobile engines, bodywork, electrical systems, automatic transmissions, body cleaning and maintenance, painting, tire dynamic balancing and repair, four-wheel alignment inspection and adjustment, fuel system maintenance and oil replacement, fuel injection pump and injector repair, crankshaft grinding, cylinder boring and honing, radiator (cooling tank), air conditioning repair, automobile decoration (canopies, seat cushions, and interior decoration), window glass installation, and other specialized maintenance operations (Category III). Below is relevant information: 1. Second Maintenance Items: The second maintenance items for automobiles include the inspection, adjustment, and lubrication of the engine, chassis, electrical components, and tires; strictly speaking, according to regulations, Category III auto repair shops definitely do not have the business rights for the second maintenance of automobiles (because Category III shops can have at most three business items, while the second maintenance of automobiles already includes four items); however, technically speaking, if a Category III auto repair shop has business rights for the engine, chassis, and electrical system, the tire part has very low technical content in auto repair. 2. Automobile Maintenance: Automobile maintenance is a general term for automobile upkeep and repair. It refers to the use of technical means to diagnose faulty automobiles, identify the cause of the fault, and take certain measures to eliminate the fault and restore the automobile to a certain performance and safety standard. Automobile maintenance includes major repairs and minor repairs. Major repairs refer to restorative repairs that use methods of repairing or replacing any automobile parts (including basic parts) to restore the automobile's sound technical condition and completely (or nearly completely) restore the automobile's lifespan.
I've been running an auto repair shop in a small county for over a decade, specializing in three categories of specialized repairs. To put it plainly, our business scope focuses on specific components rather than being a comprehensive garage that can fix anything. The most common services include engine repairs, such as replacing piston rings and repairing crankshafts—these are core components. For body repairs, we mainly do sheet metal shaping and full-car repainting. Electrical system work includes fixing car lights, replacing wiring, and repairing generators. Automatic transmission repairs are the most technically demanding projects, requiring expertise in disassembling and maintaining valve bodies. Radiator repairs are also frequent orders for us. Additionally, services like AC refrigerant refilling, brake disc replacements, and tire balancing fall under the three-category repair scope. These projects don't require large spaces; just two or three work bays are enough to get started, with minimal investment, making them particularly suitable for small-scale operators like us.
My brother has been running a Class III auto repair shop for nearly seven years, with services mainly divided into several areas: engine maintenance such as replacing cylinder head gaskets and cleaning carbon deposits; bodywork including dent repair and partial painting; electrical system checks for audio, air conditioning, and circuits; automatic transmission disassembly and repair being the most technically demanding; and frequent work on brake systems like replacing calipers and discs. Additionally, we can repair fuel pumps, adjust steering gears, and fix radiator leaks. The advantage of a Class III repair shop lies in its specialization, unlike large shops that do everything but master nothing. For example, we specialize in automatic transmissions, having invested over 100,000 yuan in disassembly tools alone, resulting in exceptionally smooth gear shifts in repaired vehicles. With the rise of new energy vehicles, we're also researching battery testing and repair services.
