I need the torque specs and sequence pattern for a water pump on a '97 F250 w/ 351 no AC ???

Answer 1

I looked it up. 20-25 FT LBS. the heads are more important as far as tightening sequence and so that is always called out.
On a water pump I would snug up the bolts going around in a circle then skipping every other one and keep that pattern and tighten to the spec. So make the sequence twice once for snug then to torque.
