Cylinder Head Assembly

CYLINDER HEAD ASSEMBLY










Tighten the bolts in sequence using the following steps and torque values :
Step 1: Tighten 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 thru 12 14 Nm (10 ft. lbs.).
Step 3: Tighten bolts 1-8, 90 degrees.
Step 4: Tighten bolts 1-8, 90 degrees, again.
Tighten bolts 9-12 26 Nm (19 ft. lbs.)

BOLT RE-USABILITY






The cylinder head bolts are tightened using a torque plus angle procedure. The bolts must be examined BEFORE reuse. If the threads are necked down (2) the bolts should be replaced.
