Alternator replacement - bolt torques

Just replaced my alternator. I couldn't find a torque for the pulley nut or any of the other 3 bolts for mounting the alternator. I looked in my shop manual and the Haynes manual. Did I completely miss these torques? Anyone know what they are?

I've had mine off many times, quick shot with the impact gun on the pulley nut and tighten the 3 bolts on the brackets with a ratchet and your good to go.

Thanks for the advice, but I always like to have numbers.

Re: Alternator replacement - bolt torques

Tighten the mounting bolts on the front of the alternator with a torque wrench to 37 foot pounds and torque the mounting bolt on the rear bracket to 18 foot pounds. Torque the nut on the alternator stud to 16 foot pounds.
