SOURCE: chevy trailblazer 4.2 6 cylinder head bolt torque in ft/lbs only and sequence

That makes no sense as the haynes manual says 22lbs per foot for bolts 1 through 14 then an additional 155 degrees for second pass and the front two short bolta where timing chain is 5.16 and front middle long bolt 3.66 lbs per foot then how can any of these specs work for a 2004 trailblazer 6cyl. When the book says this

Page 3-26 of Chilton's reads:
14. Using no sealer whatsoever, install the new head gasket(s) to the block. Clean, dry and lightly oil all head bolts threads. Install the heads and install the head bolts.

Tighten head bolts in sequence to 50 ft. lbs. (68Nm). Repeat the sequence retightening the bolts to a final torque of 105 ft. lbs. (143 Nm) and repeat the second step to ensure that all bolts are accurately torqued.

torgue chart from chilton (page 3-11) for your engine and year show:
main bearing bolts 85 ft lbs
rod bearing bolts 45 ft lbs
crankshaft damper bolts 135 ft lbs
flywheel bolts 55 lbs

Correct pressure for torque the head of mazda pickup 1998


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!

Can you tell me the torque spec.on head bolts for a 1985 ltd 3.8 thank you


Six IN LINE - 6L

zjlimited_510.jpg

Fig.: Cylinder head torque sequence - 6 -cylinder engine



Cylinder head torquing should proceed in three steps and in the prescribed order. Tighten them first to 50-55 ft. lbs. (65-71 Nm), then give them a second tightening to 60-65 ft. lbs. (78-84 Nm). The final step is to 70-75 ft. lbs. (91-97 Nm), at which they should remain undisturbed.


Six IN V - 6V

zjlimited_511.jpg

Fig.: Cylinder head bolt torque sequence - 6 -cylinder engine

Tighten the head, according to the illustrated sequence in three progressive steps. Tighten the bolts to 50-55 ft. lbs. (68-74 Nm), then 60-65 ft. lbs. (81-88 Nm) and finally to 75 ft. lbs. (102 Nm).


Hope this helps (remember to rate and commene this answer).
