the tensioner should move, certainly enough for you to remove the belt off all the pulley wheels, you have to get at the tensioner from underneath, it all can be done without removing the shroud but its tricky, it is best to remove the shroud completely so you can see what your doing, to get the alternator out you have to remove some of the pipes out of the way up top, (plus aux battery if fitted) unless you have little tiny hands, I don't, that tensioner should move easily, if it doesn't it is probably seized & needs replacing anyway, inspect the bolt as sometimes they fit a shorter bolt but it is not long enough to allow the tensioner to move freely, throw a new belt on but buy an original one from Nissan, keep the other in your truck for a spare, to tell an original from aftermarket the original will have V grooves in the belt & aftermarket have solid square grooves, the difference is the original will allow crap, water, silty muddy water to disperse from itself & the aftermarket will not, often doing water crossings the belt will squeal like a pig, the original will quiten down quicker & stay quite, aftermarket will squeal for ages & usually every morning for weeks until it has defecated the crap out of the grooves
