Auto and Shop Information for Armed Services Vocational Aptitude Battery (ASVAB) Study Guide

Updated on Jul 5, 2011


This article tells you how to prepare for the Auto and Shop Information subtest of the ASVAB. You'll learn about commonly tested concepts, including basic automotive components and systems, shop tools, and basic construction materials and procedures. As a bonus, you'll find sample questions for practice at the end of the article.

Repairing a vehicle, constructing a temporary shelter, pouring a foundation for a permanent structure— these are skills that many armed services personnel use regularly. If you choose a Military Occupational Specialty that focuses on automotive or shop concepts, you'll be preparing for a civilian career as well, as skilled workers in these fields are always in demand.

The Auto and Shop Information subtest on the ASVAB is used to help determine whether you can enter a specialty that requires this kind of knowledge. You'll do best on this subtest if you already have a fair amount of background in this area, whether from high school shop classes, jobs you've held, or just puttering around with cars and carpentry.

This article can help you review what you already know about how machines work. If you're relatively new to this area, you'll find this chapter makes a good basic introduction to Auto and Shop Information. You'll learn some of the most commonly tested tools, concepts, materials, and procedures. There are suggestions for ways to improve your knowledge by gaining hands-on experience. At the end of the chapter, you can test your knowledge with sample questions similar to those found on the ASVAB.

What Auto and Shop Information Questions Are Like

The Auto and Shop Information subtest covers a wide range of topics. The questions are multiple choice, with four possible answers. You will have 11 minutes to answer 25 questions, many of which are accompanied by pictures. Most people find that they can answer all 25 questions in the time allowed. Though some questions include all the information you need to find the correct answer, most will rely on your previous knowledge of auto and shop concepts.

A typical Auto and Shop Information question will look something like this:

  1. Which of the following is NOT part of a typical automotive cooling system?
    1. the radiator
    2. the oil filter
    3. the water pump
    4. the thermostat

The correct answer is b, the oil filter. You'll find that a few questions are like this one, using the word NOT to signal the correct answer. The oil filter is the part of the internal combustion engine that cleans the lubrication oil, so it is not part of the cooling system.

Auto Information

Much of the Auto and Shop Information subtest, as you might expect, covers automobiles and other vehicles that use an internal combustion engine. Concepts you can expect to find on the ASVAB include the various systems of an automobile and their functions, as well as how to maintain and repair a vehicle.

Automotive Systems

Cars, trucks, buses, and other vehicles all use literally thousands of components, or parts. A combination of several components that work together to perform a specific function is called a system. There are several main systems that perform key functions in the automobile: providing power, transferring energy from the engine to the wheels, keeping the engine cool, smoothing out the bumps in the road, and more. You'll learn about the most important systems and components in this section.
