Torque sequence -----------
' 9 7 3 1 5 '
' 8 4 2 6 ' ----------- Step
1: torque in sequence to 45 Ft/Lbs Step 2: torque in sequence to 65
Ft/Lbs Step 3: torque in sequence to 65 Ft/Lbs again plus 1/4
turn Step 4: Torque small bolt in rear of head to 25 Ft/Lb Recheck
final torque in sequence *** CAUTION ***engine uses
Torque To Yield head bolts (TTY) thatpermanently stretch during the
initial installation.New head bolts must be used when cylinder head
isreplaced or re-installed to obtain proper torque. 3.3L
the torque specs for your intake are the first pass to 44in/lb the second pass to 89in/lb. and the tightening sequence is as follows:
start on the passenger side (right side) the 3rd bolt (from front) is #1 then on the driver side (left side) 3rd bolt is #2 and 4th bolt is #3.Back to right side 2nd bolt is #4 and 4th bolt is #5. Left side 2nd bolt is #6 and 1st bolt is #7. Right side 5th bolt or rear most bolt is #8, left side rear bolt is #9. Then finish with right side 1st bolt is # 10.
Do that the first time at 44 in/lb then same thing over again at 89 in/lb
Step 1: torque long bolts 8,4,1,5, & 9 to 46 Ft/Lbs
torque short bolts 7,3,2,6, & 10 to 43 Ft/Lbs Step 2: torque all bolts 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.
Cylinder Head Bolt (Preferred Method)
All Bolts First Pass in Sequence
Long Bolt Final Pass in Sequence
Medium Bolt Final Pass in Sequence
Short Bolt Final Pass in Sequence
Cylinder Head Bolt (Optional On-Vehicle Strategy)
First Pass in Sequence
Second Pass in Sequence
Final Pass in Sequence
