Cylinder Head Assembly

CYLINDER HEAD ASSEMBLY






Tighten the bolts in sequence using the following steps and torque values:
Tighten bolts 1 - 10 27 Nm (20 ft. lbs.).
Verify that bolts 1 - 10 have all reached 27 Nm (20 ft. lbs.), by repeating step 1 without loosening the bolts.
Tighten bolts 11 - 14 14 Nm (89 in. lbs.).
Rotate bolts 1 - 10 an additional 90°.
Rotate bolts 1 - 10 an additional 90° again.
Tighten bolts 11 - 14 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.
