Autozone tool loan
Thanks for all the info on torque wrenches. I went looking, today, and discovered that Autozone has a tool loan program. They had a click-ratchet torque wrench which I took. There is a $90 deposit but no cost for the loan. The only problem is that when I got it home I realized the torque range is 47.5-345.7 Nm (30-250 ft/lbs) which is too big for my job. As tcane and others have noted, more than one size torque wrench may be needed. I think Autozone had only one size. At least it's not costing my anything.
I'm change transmission fluid and motor mounts. The transmission pan bolts take just 7 Nm, which isn't much more than hand tight, I guess.
