The tensioner has a little square in it that's meant to accept a ratchet or beaker bar. It's in the front side of the tensioner arm. You put a ratchet in that and push or pull the tensioner until the belt is loose. Remove the belt. Then while holding the tensioner arm still with one ratchet, you use another to loosen the pulley that's on the tensioner arm.
I've been meaning to replace mine for months now. I've got a new pulley but just haven't done it. It's been too damn cold and sloppy outside. I have looked it over though and it looks simple enough. I replaced the upper idler pulley and it can't be much different than that.
Someone correct me if there's a better way.
