Need torque specs for thermostat stud nuts & bolt

Hi folks - Daughter's 2012 Prius v threw a coolant overheating light for a few secs the other night on her way home from work so I just ordered a new pump and thermostat. Busted one of the thermostat studs taking the old one off. Had to torch the half that was left in the engine block to wrench out w vice grips but would prefer to put the brand new studs (2) and bolt (1) back in with proper torque ... not too much to break another stud but not too little to wind up with a leaky thermostat seal.

FYI, found signs the old one was leaking when I removed the air intake to get to it but probably hadn't lost much judging from the level in the expansion chamber, which was about where it always is. 148k total miles on the car and changed the coolant @136k.

Anyone know the torque specs for the 2 stud nuts and the bolt for the thermostat housing?

Thanks!

Attached pic of the leaky old one before I cracked it off.

 

Oh, might be nice if someone could also confirm same for water pump. Guy I found who had a YouTube video showing how to replace the pump offered these up:
19 ft. lbs - 2 Long Bolts (rear) on water pump
15 ft. lbs - 3 Short Bolts (2 forward and 1 bottom) on water pump

 

@Elektroingenieur - Thank you, sir (madam?)!
