This is very easy to do. you will need a open end wrench to place on the nut radiator side of the pulley moving this releases the tension and you can remove the belt. Before doing this take a picture and just memorize the directions the belt went (not that hard). release the tension and slid the belt to the side DO NOT REMOVE IT. then on do the bolts holding the tensioner on and replace with the new on (it can only go on in 1 direction so no worries) then using the picture or memory release the tension on the tensioner and replace the belt. Now enjoy your D...
I have a 99 and replaced mine already so when I say it is easy it is.
