The 2.0Liter engine is an interference fit engine serious damage occcurs if the timing belt breaks , not sure about the 2.5 Lite V6 engine. Autozone have some free on line manuals for popular cars on there web site but if you do work on your own car there is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You get a one year subscription to year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual. http://www.alldatadiy.com/
