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.

New Headbolts are recommended

Long bolts are torqued to 46'lbs + 90 degrees.

Short bolts are torqued 43'lbs + 90 degrees.

Start in the center, and work to the edges, torquing the bolts in two stages.

Rockers are torqued to 22'lbs.

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

I have a saturn 2.2 ecotec 2003 i resurface my cylinder heads and now i need to install them but i dont know the sequence and the torque for each bolt


The head bolts are t.t.y.
that means Torque To Yield.
the bolts must be tightened down to a set point, then tightened to a set degree point.
You must find this specific number for your engine......don't put it on until you have these numbers !!!

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.
