What makes you think the pulley will be in the correct place for the new belt?
You need to slacken the alternator mounting bolts and the engine end of the tensioner strap as well, and don't forget to tighten them again afterwards.
Only slacken the tensioner bolt the minimum amount to let it turn, otherwise the adjuster pinion will slip off of the side of the rack and damage its teeth.
Tighten the belt for about 10mm of deflection on the longest run when you push it with a finger, and check it again next week.
