Torque Spec for Fan-to-Clutch and Water Pump Pulley (Not in FSM)?

It's not specified in the '94 FSM.
I would refer to the standard torque recommendations:

Going from memory, I'm guessing they're 6mm studs, and unmarked, so presumed to be "4T". That would be 48 or 52 inch-pounds.
Again going from memory, I vaguely recall that the belts can pull the water pump pulley to the side a bit, causing you to fight a bunch more friction while trying to tighten down the nuts. This would give a false reading and result in under-torqued, over-stressed fasteners. Just something to watch out for.

Forgot I'd been down this road before, when the PO put 'em on so tight I had to chew them off (so to speak), piece by piece...tight enough until you think they won't come off

I snug mine down and put torque check paste on them. So far, none have moved
