These OTC System 2000 manuals are great resources for anyone working on 1981 - 1989 GM vehicles or 1989 Asian imports. To use them, simply flip through the pages to find the information you need. Whether it's for basic maintenance or more complex repairs, they've got you covered. When handling the manuals, be gentle as the covers are a bit soiled and the Imports manual has some dog - eared pages. To keep them in good shape, store them in a dry and clean place. Avoid getting them wet or dirty. If you want to mark important pages, use a bookmark instead of folding the corners. With proper care, these manuals will serve you well for a long time.
