To my knowledge it will work on both engines. I never use the holding wrench because a figured out a way to do the whole job in about 30-35 minutes. I just put the two wrenches together ; if the tolerence needs to decrease, I will turn the top one to the right and tighten the bottom nut against it. If the tolerance needs to increase, I will hold the top nut and move the bottom nut to the left and tighten the top one on it. Works great.
