what are the head torque specs?


1996 Isuzu Truck Hombre 2.2L SFI 4cyl

zjlimited_545.jpg

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).

intake to head bolt torque


Intake bolt torque is 11-14 foot pounds. Note:
to torque bolts & nuts, start in center using
crisscross pattern working outward. And as Far as the sealant goes, you shouldn't need any additional sealant since the new gasket has sealant.(just make sure both surfaces are clean an free of oil.) sometimes if the head or the block show signs of pitting on the matteing surfaces then you could use a litttle of that cooper spray gasket to coat the new gasket.
