Gmcuokan6.0engin head torque set


If you're asking about head torque specs for a GM Yukon 6.0L engine, it depends on the year and the bolt used. If it's 97-03, it should have unequal length bolts and the stock GM bolts should be torqued in sequence to 22ft lb then another pass 90 degrees and a third pass 90 on the long, 50 on the short. The 8mm bolts near the intake are torqued to 22ft lb.
make sure all bolt holes are clean and have no liquid in them or else you risk severe problems including cracking the block. The sequence can be found using google. Type "LS1 head torque sequence"

Head Bolts
Torque sequence --------- ' 6 2 3 7 ' ' 5 1 4 8 ' --------- Step 1: torque in sequence to 33 Ft/Lbs Step 2: turn an additional 90 degrees recheck final torque in sequence *** CAUTION ***engine uses Torque To Yield head bolts (TTY) that permanently stretch during the initial installation.New head bolts must be used when cylinder head is replaced or re-installed to obtain proper torque.Always coat bolt threads with the proper sealant.
The Intake Bolt Torque 10 Foot pounds (Final torque)
Note:to torque bolts & nuts, start in center using crisscross pattern working outward
