Head bolts |
The head bolts require an additional torque turn procedure. The numbers (1, 3, 4) are three long cylinder head bolts. All the other bolts are short bolts. The tightening sequence is shown in illustration 1.
- Place an index mark on the top of each bolt head. Tighten the short bolts for the additional amount. ... 225 degrees
- Place an index mark on the top of each bolt head. Tighten the long bolts for the additional amount. ... 270 degrees
