The Auto and Shop Information section of the ASVAB test measures your knowledge of vehicles and their parts, as well as the basic tools and practices used in automotive shops. This section is more in depth as it requires students to know about the different components of vehicle engines and operating systems, as well as the proper protocols used in shops. When studying for this section of the test, pay close attention to the different components involved in a functioning vehicle, the common practices followed in automotive shops, and the different types of equipment being used. With a total of 25 questions, Auto and Shop Information section must be answered in a maximum of 11 minutes.
Study the basic engine components and how they function—including how different parts of the car interact with the engine, how fuel enters and supports the engine, and how the electrical components of the vehicle impact the overall function of the engine. Know how the engine would react to malfunctioning equipment, such as a fuel injector or thermostat. You should also be familiar with the different engine types and sizes, as well as their maintenance and fix.
The operating system of a vehicle covers all aspects of a vehicle apart from the engine. This includes the transmission, electrical system, brakes, steering, and ignition. To prepare for this, you should know the basics of these systems. Learn how to identify problems with any given system and its different components and functions. You must know the purpose of a transmission, the importance of accurate steering and brakes in a vehicle, and the potential dangers present in the electrical systems of vehicles.
In addition to the basic functions of different vehicle systems, students must also understand how computers come into play in the overall operation of vehicles. This includes knowing different codes displayed by vehicle computer systems and how to respond to these codes. Though older vehicles may not have computer-based reactions, all new vehicles come equipped with computers able to connect all aspects of a single vehicle.
Automotive shops contain numerous tools and types of equipment that must be accurately identified and used by all workers. When studying for this portion of the test, work to identify basic types of tools, as well as more specific or specialized tools including extractors, veining bits, and counter gauges. Familiarize yourself with the larger tools and equipment used in automotive shops. This may be as common as lifts used to suspend cars during work, or as small as a heavy-duty drill designed to remove high-pressure bolts. Apart from tools, you must be able to identify the proper procedures used in automotive garages—such as safety tips and tricks or the operation of heavy machinery. Also study different machines used in conjunction with vehicles, including how they are used, what purpose they serve, and the proper safety procedures to follow during use. As with all tests, be sure to focus first on the questions familiar to you. This is particularly important for this test, as you are only allotted 11 minutes to answer 25 questions. Complete all simple or familiar questions before coming back around to more difficult questions. If you do not know the answer, make an educated guess and move on. Implementing both these tricks and adequate study should result in a desirable score.
