Jahan, The shop manual really doesn't specify either, however, I used loctite on mine. Anti-sieze compound can give you a false torque reading(grease in the threads) and then dry out leaving you with a loose bolt. Here is the tightening procedure from the Ford shop manual:
5. Note: Make sure key on crankshaft aligns with keyway of crankshaft pulley.
Install crankshaft pulley bolt and crankshaft pulley retaining washer. Tighten in four steps:
a. Tighten to 90 Nm (66 lb-ft).
b. Loosen one complete turn.
c. Tighten to 50 Nm (36 lb-ft).
d. Tighten an additional 90º.
You also want to use a little bit of sealant on the crankshaft keyway slot.
Hope this helps!
