Engine Torque Specifications

TORQUE






CYLINDER HEAD TORQUE & SEQUENCE










Tighten the cylinder head bolts 1-8 in sequence shown. Using the 4 step torque turn method, tighten according to the following values:
Step 1: Bolts 1 - 8 61 Nm (45 ft. lbs.)
Step 2: Bolts 1 - 8 88 Nm (65 ft. lbs.)
Step 3: Bolts 1 - 8 (again) 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.

HEAD BOLT REUSE/REPLACE






The cylinder head bolts should be examined BEFORE reuse. If the threads are necked down, the bolts must be replaced.

INTAKE MANIFOLD TORQUE & SEQUENCE

Lower Intake Manifold










Initially tighten all bolts to 1 Nm (10 in lbs.). Finish tightening the bolts in two steps, first to 22 Nm (200 in. lbs.) in the sequence shown, then again to 22 Nm (200 in. lbs.) in the sequence shown.

Upper Intake Manifold










Install and tighten bolts in the sequence shown to 12 Nm (105 in. lbs.).

ROD BEARING CAP TORQUE






Install connecting rod bolts and tighten to 7 Nm (5 ft. lbs) initially. Tighten the bolts an additional 21 Nm (15 ft. lbs.) and then turn each bolt 90° to final clamping load.
