Replacing timing belt is a big job and requires a reasonable selection of hand tools. Replacement of the timing belt is important for the reliability of your engine but its replacement must follow precise instructions! Definitely get a workshop manual specific to your car they are inexpensive. You can get one here http://bit.ly/online_repair_manuals Look on Autozone web site they have many manuals on line for free. I would send you a direct like to the page you need but there site is down right now. Your engine is an non interference engine show it is somewhat forgiving if you make a mistake.
