SOURCE: head bolts torque settings

According to my haynes manual for G-S reg, 1989-1998 it goes as follows,
Stage 1:- Tighten all bolts by hand until bolt heads just contact cyl. head.
Stage 2:-Tighten all bolts to 40Nm or 30lb ft.
Stage 3:-Angle tighten all bolts a further 60 degrees.
Stage 4:-Angle tighten all bolts again a further 60 degrees.
Stage 5:- M12 x 140mm bolts ONLY angle tighten a further 20 degrees.
Hope this helps everyone, sorry it seems longwinded but that is how it's written in the manual.

SOURCE: Head bolt torque specs needed for 96 tbird 3.8

Head bolts are torque to yeild so you MUST use new bolts.
Tighten cylinder head retaining bolts in numerical sequence in three steps as follows:

  1. 20 Nm (15 lb-ft).
  1. 40 Nm (30 lb-ft).
  1. 50 Nm (37 lb-ft)
Loosen retaining bolts one at a time two to three revolutions and retighten as follows:

Long bolts:
  • Tighten to 40-50 Nm (30-37 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
Short Bolts:
  • Tighten to 20-30 Nm (15-22 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
Here is a pic of the sequence

Cylinderhead torque settings


I'm not sure what engine you have in your 95 grand am SO I will give you both the 4cyl and 6cyl Specs. Also you didn't ask for the torque sequence. I will include that as well for both. 2.3 DOHC Quad 4cyl: Torque sequence---> front ' 7 3 1 5 9 ' of engine ' 8 6 2 4 10 ' Step 1: torque bolts 1 thru 6 (26 Ft/Lbs & 90 degree turn) Step 2: torque bolts 7 & 8 (15 Ft/Lbs & 90 degree turn) Step 3: torque bolts 9 & 10 (22 Ft/Lbs & 90 degree turn) Recheck final torque in sequence *** CAUTION *** This engine uses "Torque To Yield" (TTY) head bolts that means they permanently stretch during the initial installation. New head bolts must be used when cylinder head is replaced or re-installed in order to obtain proper torque. 3.1 liter V6 Torque sequence--> ' 6 2 3 7 ' ' 5 1 4 8 ' Step 1: torque bolts in sequence to 33 Ft/Lbs Step 2: turn an additional 90 degrees Recheck final torque in sequence *** CAUTION *** This particular engine uses "Torque To Yield" head bolts(TTY) (that means the bolts permanently stretch during the initial installation.) You MUST use NEW head bolts when replacing or reinstalling the cylinder head in order to obtain the proper torque.

What is the cylinder head bolt torque settings fir a 4g69 mitsubishi engine ?


BOLT INSTALLATION


Apply engine oil to the thread of the bolts and to the washers.
Tighten the bolts to the specified torque, using the tightening sequence shown.
Tightening torque: 54 ft-lb +/- 2 ft-lb
Loosen all bolts fully in the reverse order of tightening.
Re-tighten the loosened bolts to the specified torque in the tightening sequence shown.
Tightening torque: 15 ft-lb +/- 1 ft-lb
This step is to make it easier to ensure you are making 90 degree turns. Make a paint mark across each bolt head and cylinder head.
Tighten the cylinder head bolts 90 degrees in the specified order.
Tighten the bolts another 90 degrees in the specified order and check that the paint marks on the cylinder head bolts are aligned with the paint marks on the cylinder head.

What are the torque specs for the main & rod bearing caps on a 2000 chevy s-10 2.2?


The head bolts are toque to yield on these engines, meaning that once they have been torqued to specification, they must be replaced when removed. If it is an OHV engine (solid push rods with and internal camshaft and rockers on the head studs) there is a sequence to tightening the head bolts. First, tighten all bolts in a circular motion, starting from the center and working outwards. I prefer to go in a clockwise rotation, but as long as it is in the correct order, rotation is not important. The long bolts must first be tightened to 22 lb/ft and the short ones to 23 lb/ft. Next, in the same order as before, tighten the long bolts to 43 lb/ft and the short bolts to 46 lb/ft. Finally, in the same order as the previous two steps, torque all the bolts an ADDITIONAL 100 degrees (10 degrees past 1/4 turn). A torque angle meter is required to do this properly and to specification. A routine of mine that is not necessary, but I have found helps prevent warping when torquing the head, is when torquing to final spec of 100 degrees, first tighten 60 degrees on all the bolts in the same order as the first two steps, then an additional 40 degrees all around in the same order.


Tightening order:
8 4 1 5 9
7 3 2 6 10
