PICT0017 is the new belt installed with a bungee holding the tensioner pulley in place before the new tensioner went in. This is the point where you check that all the marks line up. PICT0014 is the markings on the crank tensioner and belt. Note that aluminum cover has been removed. PICT0011 is another angle. PICT0008 is the old belt before being removed. Remember to also mark the direction the belt travels.

The marks on the tensioner and the belt will not line up again once you have turned the belt over one full rotation. On the 94 the marks were off by 2 teeth after every rotation. It might be a different number on the later design belt. It pays to double and triple check, the number of teeth between the old and new belt. You can even line up the two belts together and visually check.
After you have the new belt installed and you are sure that everything all your calculations are correct, turn the engine over by hand a couple of revolutions to check that there is no interference between the pistons and valves. Also you can check that the new belt is running in the middle of all the pulleys so there is no chance it will pop off. When you start up the engine the first time, do so with the belt cover off. After that give it another visual inspection. This is not a difficult job but patience does pay dividends.
Also there is a curved aluminum cover underneath the crank pulley. Its a bit of a pain to remove and it has to be reinstalled before the new serpentine belt. Don't ask me how I figured that one out. Patience is a virtue.
Good luck
