Normally, the use of special factory tools are avoided for repair procedures, since these are not readily available for the do-it-yourself mechanic. When it is possible to perform the job with more commonly available tools, it will be pointed out, but occasionally, a special tool was designed to perform a specific function and should be used. Before substituting another tool, you should be convinced that neither your safety nor the performance of the car will be compromised.
When a special tool is indicated, it will be referred to by a manufacturer's part number. Where possible, an illustration of the tool will be provided so that an equivalent tool may be used. Some special tools are available commercially from major tool manufacturers. Others can be purchased from: General Motors Service Tool Division, Kent-Moore, 29784 Little Mack, Roseville, MI 48066-2298.
