i had the same exact vehicle. you don't release the tensioner, you'll have to take the presure off with a ratchet and socket. on the front of the tensioner pulley there is an arrow that has "loosen" next to it . get a socket that fits on the bolt in the middle of the pulley. ratchet the pulley towards the loosen side. there will be alot of tension so be careful. the belt will loosen when you turn it. slip the belt off the pulley and very slowly release the pressure off. it will pull against you alot but it will stop. just reverse this when putting the belt back on. also try to not take all the belt off if you don't have to, this will help w/putting the belt back on.
