It really depends on your technical / mechanical skills and tools. I'd strongly suggest to take your vehicle to a repair shop to have this kind of work done, since you'd risk a serious engine damage. If you think you can handle it with 100% confidence, you can find great repair manuals with step-by-step instructions, diagrams, parts locations and other important information here: http://bit.ly/mitchell_repair_manuals_online
