What bolt is this your tightening? As long as you have applied the correct Torque setting and the correct number of Degrees you don't need to worry about the final torque reading on the bolt. For areas like cylinder head bolts the final reading will be slightly different for each bolt.

TORQUE SPECIFICATIONS all readings in ft. lbs.

This for 2000 model I do not know the yuear of your car.

The head torquing sequence is as below:-

9....5....1....3....7
Front
10...6....2....4....8

Carry out the sequence at least three times, once at about half the torque value and then at least twice at the full value.

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!

hope this helps...please vote thanks
