civic timing belt adj bolt?

I have the helm shop manual and it refers to the timing belt adjustment bolt
after the crank is rotated to TDC. I can't see the adjusting bolt - do I
have to remove the plastic timing belt shield behind the crank pulley? I am
in the process of replacing the head gasket. 1994 civic lx 4 door sedan 1.5L
5 speed.

there's a black rubber blanking plug in the plastic cover, roughly half
way between the cam & the crank pulleys, slightly towards the rear.
take the plug out and you can get a socket wrench on it from there. all
you need to do is loosen it, then re-tighten - the tensioner is spring
loaded & does the adjustment for you. make sure you loosen it a
reasonable amount, not just barely. also make sure you bring the crank
to tdc /while/ the tensioner is loose - ***ABSOLUTELY DO NOT ALLOW THE
CRANK TO TURN THE WRONG WAY WHILE DOING THIS*** - so that it really does
pull the slack out of the belt.

You need to pull the tensioner down a bit before re-releasing it.

On the DOHC Integra, this is done by:

1) Loosen the tensioner bolt (a thinwall socket helps here), and turn the
crank *CLOCKWISE* THREE TEETH ONLY as measured at the cam pulleys.
2) Then you tighten the bolt to lock the tensioner in place.
3) Let go of the crank.
4) Loosen the tensioner again. You'll hear a noise as the spring pulls the
tensioner back up again.
5) Retighten the bolt.

Rotate the engine COUNTER-clockwise and make sure the belt has slack at
some point in its rotation. If the belt is always very snug, then it's too
tight.
