not sure about the v8's, but on an I6 you have to replace the whole thing, it's a sealed unit. As for the tensioner, if it's the same as the 6's then it should have a spring loaded pulley somewhere that you push in to release the tension

the tensioer is self adjusting, use a 1/2 or 3/8 (cant remember) drive socket to 'lever' the tensioner pulley and release the belt pressure, its on the drivers side beneth the alternator.

Pretty sure it's a 3/8 drive that does it.

Oh. That makes sense. Punctuation and proper grammar is all important, isn't it. I thought he said "You don't replace the belt" (when he actually meant "You don't. Replace the belt"), and I was thinking, well, what happens if it breaks?
