Its got a timing belt. If you don't have the proper tools and experience in working on cars you would probably be sorry you under took doing the job yourself at home. If you have power steering and a/c its about a 4 hour job to replace the timing belt. If you wanted to see how the work is carried out Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_info. and get an online repair manual subscription.
