What is the torque value on the tensioner bolt on a 98 s10 2.2? I have the Haynes repair manual and it doesn't say..

It would also be nice to correct the mis guided Haynes and store bought chiltons manual on torque specs for the pinion shaft yoke to u joint strap "bolts". Their book says 180 ft. lbs of torque which i know cannot be right. I have already busted off 3 bolts in the past attempting this (and yes they were all grade 8 or higher bolts). With those size bolts...your lucky to see 75 ft. lbs before they twist and break.

The Haynes book says "180 inch lbs"... Thats only about 15 lbs/ft. ??? Confused???

In the process of rebuilding my 2.2L, anybody know where I can find replacement hardware for engine and attaching hardware for components?
