Water pump body nut torque?

When installing the water pump, per the manual it says torque to 60-90 lbs In. (7-10 N.m) and the screw to 30-40 lbs In. (3-5 N.m) what does that translate to in ft. lbs? I do not have a torque wrench with Inch lbs

snug using a 1/4 drive socket and a weak wrist.do not distort the plastic housing.

Re: Water pump body nut torque?

divide by 12 (12 inches in a ft.) for in/lbs to ft. lbs...

60-90 in/lbs is, 5ft/lbs-7.5 ft/lbs

30-40 in/bls is, 2.5 ft/lbs-3.33333 ft/lbs

most ft/lb torque wrenches i've seen didn't go low enough....

bd might have the way for ya if yer not gonna get a new torque wrench..
