3. The cylinder head bolts are torqued using the torque yield method, they should be examined BEFORE reuse. If the
the bolts must be replaced (Fig. 51).

4. Necking can be checked by holding a scale or straight edge against the threads. If all the threads do not contact the scale t

5. Tighten the cylinder head bolts 1 8 in the sequence shown in (Fig. 52). Using the 4 step torque turn method, tighten accord
? Step 1: Bolts 1 8 to 61 N.M (45 ft. Lbs.)
? Step 2: Bolts 1 8 to 88 N.M (65 ft. Lbs.)
? Step 3: Bolts 1 8 (again) to 88 N.M (65 ft. Lbs.)
? Step 4: Bolts 1 8 turn an additional 1/4 Turn.
Do not use torque wrench for final step also just replace bolts do not reuse old bolts. Tighten per sequence shown in pic

Tighten the cylinder head bolts 1-8 in the sequence shown in (Fig. 20). Using the 4 step torque turn method, tighten according to the following values:

Step 1: Bolts 1 - 8 to 61 Nm (45 ft. lbs.)
Step 2: Bolts 1 - 8 to 88 Nm (65 ft. lbs.)
Step 3: Bolts 1 - 8 (again) to 88 Nm (65 ft. lbs.)
Step 4: Bolts 1 - 8 turn an additional 1/4 Turn. (Do not use a torque wrench for this step.)

NOTE: Bolt torque after 1/4 turn should be over 122 Nm (90 ft. lbs.) . If not, replace the bolt.

Torque lower intake manifold bolts in 3 steps. Step 1: Tighten all bolts in sequence to 1 Nm (10 in. lbs.) .

Step 2: Tighten all bolts in sequence to 22 Nm (200 in. lbs.) .
Step 3: Tighten all bolts in sequence (again) to 22 Nm (200 in. lbs.) .

UPPER INTAKE MANIFOLD
Tighten intake manifold bolts in sequence to 12 Nm (105 in. lbs.) .
