The Head Bolt Torque

Torque sequence -------------- front ' 6 1 3 7 ' of ' ' engine ' 5 2 4 8 ' -------------- Step 1: torque to 20 Ft/Lbs Step 2: torque to 47 Ft/Lbs recheck final torque in sequence

Cylinder head bolt torque sequence
The Rod Bearing Cap Torque
The Main Bearing Cap Torque 38 Foot pounds (Final torque)


Step 1: Torque 10-12 Ft/LbsStep 2: Torque 17-21 Ft/Lbs


Note :
Torque sequence ------------------------

------------------------
Step 1: Torque all bolts in sequence 22 Ft/Lbs
Step 2: Torque all bolts in sequence 47 Ft/Lbs
Step 3: Loosen all bolts in reverse sequence
Step 4: Retorque all bolts in sequence 22 Ft/Lbs
Step 5: Retorque all bolts in sequence 43-51 Ft/Lbs
Step 6: Retorque bolts 11 thru 15 in sequence an
additional 4-6 Ft/Lbs
** CAUTION ** This engine uses 2 different length head
bolts. "#1" Is the long bolt, while remaining bolts
are short. **Do not confuse location of these bolts**
recheck final torque in sequence

Torque sequence ------------ front ' 6 4 2 8 ' ' 5 1 3 7 ' ------------ Step 1: torque in sequence to 59 Ft/Lbs Step 2: loosen all bolts in sequence (1) full turn Step 3: torque in sequence to 40 Ft/Lbs Step 4: torque in sequence to 73 Ft/Lbs recheck final torque in sequence

Torque sequence: ----------------- there are two rows of fasteners and you need to start with the middle 2 fasteners first and then work your way toward the front and back in steps. Step 1: torque head bolts #1,2,3,4,5,6,7, & 9 in sequence to 10 Ft/Lbs Step 2: torque head bolts #1,2,3,4,5,6,7, & 9 in sequence to 20 Ft/Lbs Step 3: torque head bolts #1,2,3,4,5,6,7, & 9 in sequence to 29 Ft/Lbs Step 4: turn all head bolts in sequence an additional 90 degrees Step 5: turn all head bolts in sequence an additional 90-degrees recheck final torque in sequence. Fasteners are supposed to be replaced if they are removed since they are torque-to-yeild fasteners.

Since you didn't say which engine you have, I've pulled torque specs for 3 different engines. Also, since I can't include a diagram showing the relative locations of the numbered head-bolt locations, it would be a good idea for you to purchase a vehicle specific repair guide that will show this info.

Take particular note about the TTY (Torque to Yield) bolts used on 2 of the 3 engines shown. It is said that new head bolts MUST BE USED when head is replaced or re-installed to obtain the proper torque.

Torque sequence: --------- ' 10 6 2 4 8 ' front ' ' ' 7 3 1 5 9 ' -----------Step 1: torque in sequence to 51 Ft/Lbs Step 2: torque again in sequence to 51 Ft/Lbs Step 3: final tighten all bolts an additional 90 to 100 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.

B3000 3.0 6 Cylinder

Torque sequence ---------- ' 6 4 2 8 ' ' ' ' 5 1 3 7 ' ---------- Step 1: torque to 59 Ft/Lbs Step 2: loosen in sequence (1) full turn Step 3: torque to 41 Ft/Lbs Step 4: torque to 73 Ft/Lbs

B4000 4.0 6 Cylinder

Torque sequence --------- ' 5 1 3 7 ' ' ' ' 6 4 2 8 ' --------- Step 1: torque cylinder head bolts in sequence to 26 Ft/Lbs Step 2: torque cylinder head bolts to 56 Ft/Lbs Step 3: turn cylinder head bolts in sequence 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.

Good luck with this job!

Cylinder heat bolt torque:
Torque sequence --------- front | 7 3 1 5 | | 8 4 2 6 | --------- Step 1: Torque all bolts in sequence to 14 Ft/Lbs Step 2: Torque all bolts in sequence to 29 Ft/Lbs Step 3: Torque all bolts in sequence to 36 Ft/Lbs Step 4: in the sequence, loosen the cylinder head bolts three turns. Step 5: Tighten short bolt to 15 - 32 Ft/Lbs Step 6: Tighten long bolt to 30 - 36 Ft/Lbs Step 7: Tighten all bolt to 175- 185 degree note: Do not loosen all of the cylinder head bolts at one time. Each cylinder head bolt must be loosened and the final tightening prior on the next bolt in the sequence.
