(1) Cylinder head studs
Install the cylinder head studs with the following procedure:
- Coat the lower half of each stud with 1.5 mm (.06 inch) thick coating of 4C-4774 Water and Temperature Resistant Grease .
- Thoroughly clean the top of the cylinder block.
- Install the cylinder head studs.

Tighten the nuts by hand. Slowly release the pressure.
- Repeat Step 5.
(10) Tighten the side bolts according to the following procedure.
- Start at the front face of the block.
Tighten the side bolts on the side of the cap opposite the tab slot to the following torque. ... 215 ± 40 N·m (160 ± 30 lb ft)
- Start at the front face of the block.
Tighten the side bolts on the side of the cap with the tab slot to the following torque. ... 1825 ± 175 N·m (1340 ± 130 lb ft)
- Start at the front face of the block.
Tighten the side bolts on the side of the cap opposite the tab slot to the following torque. ... 1825 ± 175 N·m (1340 ± 130 lb ft)
(11) Width of main bearing cap ... 499.95 ± 0.03 mm (19.683 ± .001 inch)
