X2 - What Ritter said. I have one of those, picked it up at Autozone some time back. If it won't spin far enough to get to the ft/lbs you want, loosen the nut a little more. Once you got it set, you can tighten the nut back down to hold the torque without slipping.


- oh I see yours is screwed. never mind, take it back.

You also should really tighten bolts in a sequence by "sneaking" up on the recommended torque value. If you have a bolt that requires it be tightened to 90 ft. lbs. then I would set the wrench to 30 ft. lbs. tighten the bolts in the proper sequence and reset the torque wrench for 60 ft. lbs, repeat the tightening sequence and finally set it for the 90 ft. lbs. and finish torquing.

A torque wrench is something that you should really spend good money on and Autozone would be the LAST place I would buy a precision tool from.

x2 what he said And a good manual or at least at the very minimum look it up on the internet for the proper torque spec and tightening sequence.. Also some require the bolt threads/bolt head to be lubed with fresh oil or if you use aftermarket bolts they sometimes can require a different torque value as well. As for the digital one's i bought a Snap-on 1/2 in drive for 300 a while back without the angle meter.... I recently bought a Cornwell 3/8 digital with a built in angle meter for a around the same. I use mine quite a bit at work and here at home so If you plan on doing a lot of engine work then it's definitely worth the money. Also DO NOT DROP it or use one as a breaker bar/hammer as it will throw the calibration off. Most tool dealers have a torque guage to to test them and if not up to par then send them out for calibration/repair.. The price on the digital one has come down quite bit lately and even a moderately priced one should to the trick. These are hella cheap 8) i may have to get me one for the house and keep the good ones at work!

Well I have a cheap one from Autozone. I actually used it yesterday, and it works good enough for me. As long as you know how to use a torque wrench....

You can rent one like that craftsman from the parts store loan a tool program. Its a $100 deposit though.

If your putting heads on a 3.8 you need a angle toque wrench to do them the right way..also new head bolts. So that wrench you have is just as good as tightening from center out as tight as you can get them.

the torque to yield head bolts were used in 85 and up 3.8's
