Turn the crankshaft so that the little dimple in the sprocket
is at 7 o'clock.

The "Intermediate Sprocket" also has a dimple... align it
with the edge of the front flange (the 2 little red dots).

With the 2 little red dots aligned, remove the distributor
cap and make sure that the rotor is pointing at the #1 notch
in the distributor housing.

That just leaves the camshaft... there should also be a little
dimple on the sprocket, it needs to align with the edge of
the valve cover (alternator side).

Once everything is aligned, install the belt.

If you have any doubts, post pictures and we will confirm.

Is there any adjustment with the tensioner. Does anything need to be offset before everything is done.

When you route the belt, start at the camshaft, then down
to the intermediate shaft, around the crankshaft and then
past the tensioner.... this will ensure that all the belt
slack is by the tensioner.

Adjust the tensioner so that the belt can be twisted 90 deg
(grab belt 1/2 way between camshaft sprocket & intermediate
sprocket).

When a belt is too tight, the tensioner will whine.

When the belt is too loose, the belt will rattle against the
timing belt cover.

Don't forget to check/adjust timing after you get it running.

Some technicians may recommend that you replace the water pump during a timing belt job even if there is nothing wrong with it. This is because 90% of the labor to change the water pump has already been done with the timing belt job and some technicians consider it good insurance to replace the pump at this time.
