Automotive technology coursework begins with basic shop practices. Students become adept at differentiating between tools that include wrenches, screwdrivers, mallets, dollies and spoons. They're trained to effectively and safely use tools for techniques such as prying, drilling, loosening and tightening. The proper storage of tools and hazardous materials is covered, as well as general shop maintenance protocol.
Cars contain a number of electrical components. The theories and concepts around electricity, including Ohm's Law equations, are introduced in automotive electricity classes. Students learn to identify malfunctions in electrical systems. They become proficient in reading wiring diagrams necessary to repair parts such as the battery, ignition switch and starter motor. The use of analog meters, test probes and other testing equipment is mastered. Students also become familiar with series and parallel circuitry.
Automatic transmissions, drive trains and transaxles for passenger vehicles are explored in automotive transmission and transaxle classes. Students learn to use scan tools and retrieve trouble codes. They review clutches and clutch operation devices. Servicing the torque converter and other components of a vehicle's automatic transmission is covered. Automatic transmission maintenance, including performing basic procedures like changing transmission fluid, is reviewed.
In steering and suspension classes, students receive an overview of the theory behind automotive chassis and steering systems. Hands-on training in chassis repair is a focus. Four-wheel alignment is studied also, as well as the disassembly and troubleshooting of both manual and power racks. Students are taught to inspect and replace malfunctioning power steering pumps, mounts, seals, belts and pulleys. They receive training in the installation of coil springs and spring insulators.
A course in engines familiarizes an automotive technology student with the healthy operation and repair of engines. Areas of focus include an introduction to ignition components and systems, fuel delivery and emission control devices. Upon completion, a student is able to execute tasks such as reading spark conditions and fuel levels, as well as resolve the full gamut of engine running problems.
In classes that concentrate on brakes, students learn to use brake system pressure and travel calculations. They complete service work orders and diagnose poor stopping, pulling or dragging caused by a faulty hydraulic system. They determine how to inspect brake lines and hoses. Drum brake repair and replacement procedures are presented. Through hands-on body shop activities, students are taught to remove, inspect and service bearing and hub assemblies.
The HVAC systems of cars are the focus of heating and air conditioning classes. Students are shown the basic principles of refrigeration cycles. They learn the relationship between heating and cooling and how to diagnose malfunctions. Guidelines for handling refrigerants and refrigerant replacements are introduced. Upon completion, students should have the ability to open the hood of most cars and restore their heating or cooling levels.
