    This is actually for our 98 mustang 3.8L V6. I have a under drive pulley but I am wondering if there is a torque spec. I have a torque wrench.

    Just did mine, and going from memory (this is for the '01 too), the crank bolt is 125 ft/lb and the pulley bolts are like 30 ft/lb. To tighten the crank bolt, you'll need to keep the engine from turning. 125 ft/lb is a lot.

    that sounds right to me, I was going to say it, but didn't want to just throw out a guess.
