Hey Doc do you have the torque requirements for part #90116-08270? These are the three stud bolts that the water pump slides onto and then the thermostat housing is fastened with three nuts. I think all the nuts call for 14ft lbs but have been unable to find the stud bolt torque spec. Thank you
You can probably use the same spec as the nuts but it's not as critical since there is no clamping force created by the stud, rather the nuts do that; you just don't want these backing out. I would use thread locker on the stud threads. Regardless, it would be a good add to the first page.
EDIT: the studs are mentioned here under Cooling System --> http://www.toyota-4runner.org/3rd-gen-t4rs/200181-torque-specs-service-information-revisited.html
Cylinder Head Cover is the same as Valve Cover?Cylinder head cover x Cylinder head-53 in.·lb
