Using a Torque wrench
I got a new torque wrench for Christmas and wanted to know how to determine I got to the correct "torque"? I read the manual and it stated you will hear an audible click when the correct torque has been applied. However, you can over torque it if you miss the point. Is it a soft click or can you feel thru the wrench? Thanks

wrench
It'll be pretty hard to miss unless you are in a very noisy environment.
Just to experiment, set it low...like 25-40 lbs, then put it on a lugnet on your car. Turn to tighten and it'll click long before you over tighten the lug. Thats the sound you'll hear.

And read all instructions regarding installation of part to be torqued, as some things require an additional 1/4 turn? beyond the torque setting, from my distant memory. Anyone else here want to confirm or deny this?

Some head bolts ask for a specific torque setting and then an additional 1/4 turn or so for proper tightening. It all depends on instructions from the shop manual. It is not a routine thing to do with most bolts however.
