noooo....use a little locktight on the threads.its only wrist tight.do not use the full lever value of the handle of the wrench.go too tight,youl be back with some more questionsI dont have a torque wrench, how tight should I tighten the water impeller nut? As tight as I can?
Snap. Yep that was to tight.
The second question is how much work does it take to fix a snapped off set of threads. It has been done and you don't want to know.
Also Harbor freight has basic 1/4 drive torque wrenches. Some may argue that they aren't calibrated right but 0-10 pounds is just fine.
I just torqued some head bolts on a Jeep with the 1/2 inch Harbor freight torque wrench. Then I went to use it on the valve cover gasket. 140 pounds to 8. Watched my buddy snap the bolt off. So I grabbed the wrench and did the same. Totally not accurate less than ? pounds.
