The correct tourqe is 30ft/lbs. Ford has issues this in one of their TSB's telling people to re-tourqe them to 30ft/lbs.
The kit that I used on Friday was made by Heli-Coil and came as a pack I got a Tap, Set tool, and 3 different solid inserts. This kit only cost me $32.23+tax and only set me back about 20min repaired and running. It doesn,t look like a temporary fix style kit to me and I will use it again. But, I would recommend possibly putting one in your glove box and hope you never have to use it. Also don't forget to throw in a small package of grease and wipes.
If you want the Heli-coil part number for this kit I can get it and you can get just the inserts so you could use the Tap and set tool again if need be.
