how do i replace my timing belt on the 3.0l v 6 enging and do i need a manuel ?

Go to wwww.alldatadiy.com and spend the $26.95.

It's a 4 to 4.5 hour job for a trained mechanic and is not to be taken on lightly at home without having proper instructions (Alldata is the best) but proper tools and automotive knowledge is needed to properly do the work.
