Engine Torque Specifications
All torque specifications provided in this table are those recommended by FORD. If you use special bolts, follow the torque specifications provided by the manufacturer. I recommend that you use the 3 step torque technique where you torque down the bolts in three equal steps. Once you have reached the maximum recommended torque setting, go around one more time. Do not torque in a circular pattern. Always torque cross to cross or pattern specified by FORD. Many specs are given in inch pounds. 12 inch pounds is equal to 1 foot pound. The use of a inch pound torque wrench is desirable because it is more accurate at most lower settings.
