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.

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.
