1. Clean and inspect the head bolts and threads. Replace any damaged bolts or threads.
2. Apply a thin coat of engine oil to the head bolts.
3. Insert the head bolts into the cylinder head and hand-tighten them until snug.
4. Follow the torque sequence below, tightening each bolt in increments until they are fully tightened.
Sequence:
| Step | Bolt Number | Torque (ft-lbs) |
|---|---|---|
| 1 | 1 & 18 | 25 |
| 2 | 14 & 13 | 25 |
| 3 | 3 & 16 | 25 |
| 4 | 2 & 17 | 25 |
| 5 | 5 | 25 |
| 6 | 8 & 11 | 25 |
| 7 | 6 & 12 | 25 |
| 8 | 9 & 10 | 25 |
5. Recheck the tightness of all the head bolts after the engine has cooled.
