Bolts-Cylinder Head






NOTE: 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.
Necking can be checked by holding a straight edge against the threads. If all the threads do not contact the scale, the bolt should be replaced.

NOTE: The cylinder head bolts are tightened using an torque angle procedure.

Tighten the bolts in sequence using the following steps and torque values:
- Step 1: Tighten bolts 1-10, 20 Nm (15 ft. lbs.).
- Step 2: Tighten bolts 1-10, 47 Nm (35 ft. lbs.). Tighten bolts 11-14, 25 Nm (18 ft. lbs.).
- Step 3: Tighten bolts 1-10, 90 degrees. Tighten bolts 11-14, 30 Nm (22 ft. lbs.).
