I take it that you're trying to leave the crank pulley in place and just work on the cam alignment?
The tensioner has to come off on both the I4 and V6 to give you enough slack. After that, on the V6, you either remove the belt from the rear bank or loosen/remove the idler. The idler may be difficult to put back if you loosened/removed it and there wasn't enough slack however.
But the key when it's a little off is to use a breaker bar and socket to rotate the cam sprocket to help align the belt while it's loose, instead of moving the belt itself.
And when you are all done, reinstall the tensioner, rotate the crank 2 revolutions and double check the timing marks.
