FOREWARD/TABLE OF CONTENTS FOREWARD This program was conceived and produced by NAPA manufacturers as a part of their effors to maintain the high standard of product knowledge and helpfulness to the customer that has characterized NAPA for years. The following NAPA manufacturers have made sub stantial contributions to the production of this manual: Echlin, NAPA Batteries, Rayloc, NAPA Lamps, NAPA/ Champion Spark Plugs, NAPA Exhaust, Belden, and NAPA Filters. When you complete this course you should know about each of the important systems on a car, basically how it works and how it is kept in good repair. This part of the: study course deals with the electrical, fuel and emission systems, their components and what is needed to maintain them. When you've worked your way through this manual, you'll be able to recognize the parts of each of these systems, and you will have important information about things you should con sider in their repair and maintenance. As you read through the manual you'll notice that the material is presented in two different kinds of type. The material in this type is of a more general nature and is important to anyone who wants to know about the system. The material in lighter type (like this) is more technical and usually deals with topics such as problems and solutions and installation procedures.
