Brief Description: Tools: ACDelco digital torque adapter
Important to torque everything as specified by the manual, and I found this works perfectly. The most common torque spec is 70 inch-pounds, but most torque wrenches read in foot-pounds, and start at 10 ft/lbs, which would be a minumum of 120 in/lbs. This instrument is small, accurate, fits on your existing 3/8" socket wrenches, and will read in all types of measurements, but you can set it to default in inch-pounds. It's also good about remembering the last max torque you set, and gives an audible warning before and when the torque target is reached. $60 from Amazon.
