This manual was prepared in close cooperation with British Leyland Motors in order to provide complete, authentic, and up-to-date maintenance and repair information to owners, dealership service departments, and other professional mechanics. The Workshop Manual is the official factory manual and includes information from the Driver's Handbook, which is the handbook provided with every new Austin-Healey. This manual contains emission control information that applies specifically to Austin-Healeys manufactured for the United Kingdom and North American markets, and a complete, illustrated catalogue of special tools. Because the value of Austin-Healey 100-Six and 3000 sports cars is increasing, it is impossible to overstate the importance of correct maintenance and repair. This manual has been published in order to supply complete, accurate, and comprehensive maintenance and repair data to both car owners and professional mechanics.
