It would be hard to explain without illustrations. Autozone have some popular workshop manuals for free on line once you register (for free) on their website There is also a company that independent auto repair shops buy their information from that the same information inexpensively to do it yourselfers. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate
