Hi All, Long story but the instructions that came with my Torque Wrench were incorrect resulting in readings being short by 10 ft/lbs, the manufacturer has since reissued correct instructions. I had a slight weep from my thermotat housing which until the new instructions were issued would have been tightened down at 20 ft/lbs, now I have tightened to 30 ft/lbs all is ok. I replaced the water pump a few weeks ago which means I would have also tightened to 20 ft/lbs and it should have been 30ft/lbs, it has not leaked. Should I re tighten to 30ft/lbs or leave it alone. Do I risk starting a leak by tightening to correct torque at this late stage. I used gaskets and Permatex 2. Your comments would be much appreciated.
