CYLINDER HEAD TORQUE & SEQUENCE






Tighten the bolts in sequence using the following steps and torque values:
Step 1: Bolts 1-8 27 Nm (20 ft. lbs.).
Step 2: Verify that bolts 1-8, all reached 27 Nm (20 ft. lbs.), by repeating step-1 without loosening the bolts Tighten bolts 9 through 12 to 14 Nm (10 ft. lbs.).
Step 3: Tighten bolts 1-8 90 °.
Step 4: Tighten bolts 1-8 90 °, again. Tighten bolts 9-12, 26 Nm (19 ft. lbs.)
