Developed during a project designed to provide continuous, performance-based vocational training at the secondary and postsecondary levels, this instructional guide is intended to help teachers implement a laterally and vertically articulated secondary level automotive mechanics program. Introductory materials include descriptions of Automotive Mechanics I and II, descriptions of secondary and postsecondary automotive mechanics programs, postsecondary course descriptions, secondary level automotive mechanics objectives, suggested automotive mechanics curriculum levels, suggested guidelines, discussion of sample tests provided in the guide, and suggested instructional time. Topics covered in the 13 units include an introduction; lubrication and vehicle operating maintenance; automotive engine maintenance, repair, and overhaul; fuel system maintenance and repair; emission controls and exhaust systems; cooling system, heater, and air conditioner maintenance and repair; electrical ignition systems; drive train; wheels and tires; steering and suspension; braking system maintenance and repair; automotive servicing; and servicing diesel fuel injection systems. Suggested instructional time and task listings begin each unit. For each task in a unit, some or all of the following are provided: performance objectives, performance actions, performance standards, recommended sources, related technical information, and other information the teacher might need. Appended to the basic document are: (1) a set of appendices that are relatively standard for the items in this series, and (2) a set of outcome-referenced tests. (YLB)
