the crankshaft pulley has a alignment mark on it and it should align with the mark on the timing belt cover, diagram shows it at 6 o'clock. I'm pretty sure when you get the #1 cyl at TDC the mark should be aligned. The cam pulley also has a knotch on it and that should align with the mark on the cover, diagram shows it at 12 o'clock.
You'll want to pay attention to the marks alignments after you put the belt on and set the tensioner. It sometimes will not be where you think it is and once the tension is set it may be a tooth off. You need to allow for the tension because when you tighten it up the belt will move the pulleys and could throw it off some.
