How do you get the correct tooth for the timing belt?
The timing belt itself how do you really get it on? I know the zero tolerance for teeth but whats is the correct way of putting it back on?

assuming you have the right tools, you need to lock the crank shaft, and lock the cam shafts with the cam lock bar. Then pop the sprockets loose. Replace your rollers, pump etc with the lock bar in place. put the t-belt back on. You do not need to count teeth because everything is locked in place. tension the belt, and then Tighten the sprockets.

No...
Your setup should look like this. the pic is from a 2.8 but it the same. The bar across teh engine is locked on the cam sprockets.
(edit: added) You need to loosen the bolt in the center of each sprocket with the cam lock bar on. Then use a gear puller to pop them loose from the cam shaft. They are held on by compression. Once they are loose, then put the belt on, tension the roller, pull the pin and THEN tighten the cam sprockets. The theory is, if cams and crank are locked, it does not matter where the teeth are. Its hard to understand this at first but once you get it it makes complete sense.
