Getting the engine of your Cadillac tuned up can help give you a few more miles to the gallon, and with the ever-increasing cost of gas, it is a sensible thing to do. You can save some money during the process by completing the job yourself, with guidance from the Cadillac repair manual. You can find the correct version for your vehicle, often with a choice between several publishers, in our large online catalog, and always at a great price. The Cadillac repair manual will guide you through the process, step by step, listing all of the items that must be changed, such as the spark plugs, spark plug wires, and filters. Using illustrations and photographs, it will show you the locations of the components and demonstrate some of the more difficult steps. When the spark plugs are removed, there is a guide in the back of the Cadillac repair manual that will help you diagnose engine problems, by showing you common spark plug conditions and explaining the causes of the conditions. The Cadillac repair manual can also walk you through almost any other repair, ranging from testing and replacing the alternator, to changing the valve cover and head gaskets. It also contains a large amount of reference material, such as a detailed troubleshooting guide and a full maintenance schedule.
