General Motors Torque Specs

Engine Torque Specs     Choose the GM engine family. Head bolts, mains, rods, manifolds, covers, and other fasteners belong with the engine that actually uses them.

Transmission Torque Specs     Choose the GM transmission model. Band adjustments, valve bodies, pumps, pans, housings, and other hardware need the model-specific values and procedures.

Bottom Line

Find the right engine family or transmission model first. Then use its torque values and procedures. A familiar badge won’t tighten the wrong bolt for you.
