Torque specs! i have a 1996 subaru outback and i want to know what i should torque the cylinder head bolts to?

The torque specs are
-for intake manifold-to-cylinder head bolts/nuts
1996 and later-----132 in-lbs
-for intake manifold, upper to lower bolts
1995 and later-----89 in-lbs
-for cylinder head bolts
2001 and later----step 1--37
step 2--Turn an additional 120 degrees
I hope that this helps you out.

In sequence,
torque the cylinder head bolts. Torque: 30 Nm (22 ft-lbs).
In sequence,
torque all bolts. Torque: 50 Nm (37 ft-lbs)
In sequence, turn each bolt an
additional 90 degrees.

Tighten the cylinder head bolts to 50 N·m (37 lb ft) in sequence.

Use a torque angle meter to rotate each cylinder head bolt 120 degrees in sequence.

Use a torque angle meter to rotate the four center cylinder head bolts an additional 30 degrees in sequence...

I hope this helps.

1996 Isuzu Truck Hombre 2.2L SFI 4cyl

Fig.: Cylinder head bolt torque sequence-2.2L engine

Apply a coating of 1052080 or equivalent sealer to the cylinder head bolt threads. Install the cylinder head bolts (within 15 minutes of sealer application), then tighten them in the proper sequence first to a torque of 46 ft. lbs. (63 Nm) for long bolts or to 43 ft. lbs. (58 Nm) for short bolts and then tighten all bolts an additional 90 degree turn using a torque angle meter.

Hope this helps (remember to rate this answer).

sure. 2.5 liter engine, right? Thanks for using FixYa!

Secure the head in place with the mounting bolts. Coat each bolts with clean engine oil, and hand-tighten. Tighten the cylinder head bolts to the following specifications:

1. Step 1: all bolts to 22 ft. lbs. (29 Nm).
2. Step 2: all bolts to 51 ft. lbs. (69 Nm).
3. Step 3: loosen all bolts by 180 degrees, then loosen an additional 180 degrees.
4. Step 4: bolts 1 and 2 to 25 ft. lbs. (24 Nm).
5. Step 5: bolts 3, 4, 5 and 6 to 11 ft. lbs. (15 Nm).
6. Step 6: all bolts plus 80-90 degrees.
7. Step 7: All bolts plus 80-90 degrees.

Position the cylinder head on the cylinder block. Tighten the cylinder head bolts in 2 steps following the proper torque sequence. The first step is 37 ft. lbs. (50 Nm) and the second step is 68 ft. lbs. (92 Nm).

For 1996 Chevrolet Cavalier 2.2L SFI OHV 4cyl the check the next Head Bolt Torque sequence...

------------ front | 8 4 1 5 9 | of | | engine | 7 3 2 6 10 | ------------

Step 1: torque long bolts 8,4,1,5, & 9 to 46 Ft/Lbs torque short bolts 7,3,2,6, & 10 to 43 Ft/Lbs
Step 2: torque all bolts 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.

Hope helps (remnember rated this).

The cylinder head bolt torque is a 2 step process.

First: Torque all of the bolts to 45 Nm (450 Kgf-cm or 33 ft lbs.)
Replace any head bolt that will not torque to the above specs.

Second: after all ten bolts are torqued to the above specs, the head bolts are then "Torqued to Distance"...

Starting at the center bolts, retorque all ten bolts an additional 90 degrees.

Hope this helps, the graciousness of a FixYa rating would be greatly appreciated.
