Torque's for water pump bolts needed

[LEO5651]

Can anyone give me the torque's values for the four water pump mount bolts.
Seems as both my books show how to re-build a water pump but no info on installation, sealants (if any), nor torque values.
I know its a one job but would like the torque's for reference. 2F engine.
Thank you in advance.

Try google for "ih8mud: torque"

You'll see a link with "misc torque specs" in it - it's in the MUD FAQ - water pump bolts should be in there

Thanks I did see that and the only W/P torque was for an F engine from 1964 FSM, might be the same as our 1980 CND 2F.
Not a big deal I will sit down and compute the torque values from my generic torque table as I was trained to do. Just looking to save a few minutes.
Just picked up new bolts for thermo housing and pump so I will use them as reference.
Thanks again.

Maybe 27ft/lbs... google of "ih8mud: 2f water pump torque" produced THIS

I can't imagine that physics or materials science changed much since '64.

The two things that change are:
WP construction: E-74 are cast iron.
75-newer is AL

And the bolt pitch: E-84 are M10x1.5 (coarse thread).
85-later are M10x1.25 (fine).

Well I got my lazy butt into gear and found the torques I needed. If anything I need to post the findings for the next guy, that would be the nice thing to do since you guys took the time. It's the snow.
Jim is absolutely correct in what he says - materials change in the years and so do the requirements.
Thanks guys I appreciate you help and time.
Findings

Torques for mounting bolts-1980 FJ40 2F - water pump - W/O oil cooler - with fan clutch.

1 bolt W/P - longer for alternator bracket and spacer PN 90101-10269, #7, 10mm x 60mm with 1.5 pitch Torque 27-37 ft. lbs.
3 bolts W/P - short for W/P body PN 91212-51040, #5, 10mm x 45mm with 1.5 pitch Torque 20-30 ft. lbs.

Torque for thermostat housing to engine head

2 bolts T/S PN 91612-61025, #6, 10mm x 20mm with 1.25 pitch Torque 22-32 ft. lbs.

Torques are for when no extension device are used.

I've always heard that torque values are for the BOLT being torqued, not the item being fastened. I'm sure there is an equation for the material the bolt is threaded in to as well, such as aluminum, steel or cast iron, but I'm not smart enough to know all that...lol. Good on ya to post up those findings! Good luck on your build!
