Cylinder Head Bolt Torque Specification GM 3 1L and 3 4L Engines

if the 8th number om your VIN is a "J" then this is the correct prossess 3.1LTorque sequence --------- ' 6 2 3 7 ' ' 5 1 4 8 ' --------- Step 1: torque in sequence to 37 Ft/Lbs Step 2: turn an additional 90 degrees 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.Always coat bolt threads with the proper sealant.

if the 8th number on your VIN is a "M" then this is the correct prossess 3.8LTorque sequence --------- ' 6 2 3 7 ' ' 5 1 4 8 ' --------- Step 1: torque in sequence to 37 Ft/Lbs Step 2: turn an additional 90 degrees 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.Always coat bolt threads with the proper sealant.

Please refer to the following "GM Tech Solutions Guide" on the Head bolt torque procedure for the 3.1 and the 3.4 V6 engines, Follow the link please.

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.

B2500 4 Cylinder

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!

heres the torque specs and the way to tighten the head bolts for your 1998 toyota sienna, hope this helps,
