It should say in the BGB. Which you can view for free at celicatech.com if you don't have one

The bgb that Walker and are are using doesn't seem to say anything about a snapped timing belt, just how to replace the existing one.

Unless we missed that portion....

unlike the crankshaft which revs two times per engine cycle, the camshaft only revs once. so you can turn the camshaft pulley until you see the U-notch without messing up the timing.

the real problem lies with the crankshaft. the bgb doesn't tell you how to set the crank after the belt snaps. since your belt snapped on you, you won't know whether the 1st piston (the one closest to the timing belt) is in the beginning of the intake stage or combustion stage of the engine cycle while the crankshaft pulley is on the zero degree mark. but there is a way to figure it out. you need to set it to the beginning of the intake stage (ie. piston at TDC), here's how:

Alternative method: This step may require 2 people to do. Remove the #1 spark plug, put your thumb or hand over the spark plug hole to seal it and turn the crankshaft pulley until you feel the air push out. This means the piston is in the compression stage. You need one more revolution to be at the beginning of the cycle (ie. at the beginning of the intake stage and end of the exhaust stage). Use a long straight object like a straightened coat hanger and put it through the spark plug hole lighly resting on the piston inside. As you turn the pulley on its final revolution, the coat hanger should rise to the highest position. Adjust going back and forth on the crankshaft pulley per unit degree until you reach maximum height.

Perfect - thats what I needed; thank you Gerald.
