Head Bolt Torque Specs
Head Bolt Torque Specs
HELP! Have misplaced the specs for the head bolts on my 97 2500 12-valve. This is the second time to replace this head (first time did not have it milled, big mistake). I need to know the sequence and ft. lbs. for each set of bolts.
Step 1-Tighten all bolts, in sequence, to 90 Nm (66 ft. lbs.) torque. Check the torque. If lower than 90 Nm (66 ft. lbs.) , tighten to this torque.
Step 2-Tighten all long 12 mm bolts (Nos. 4, 5, 12, 13, 20 and 21), in sequence, to 120 Nm (89 ft. lbs.) torque. Check the torque. If lower than 120 Nm (89 ft. lbs.) , tighten to this torque.
Step 3-Tighten all bolts, in sequence, an additional 90 degrees.
This is how alldata shows the proper torque procedure....
